Available literature covers the principles for making manufacturing more sustainable, but there is little, if any, practical guidance to show how to apply these principles. Lower level guidelines are required to provide guidance on systematically analysing manufacturing facilities and to assist with the identification and selection of improvement opportunities. This paper reports on work to develop guidelines for Material, Energy and Waste (MEW) process flow modelling to support the pursuit of sustainable manufacturing. Using qualitative MEW process flow maps of a case facility, data was collected to build a spreadsheet model aligned to each of the MEW process flows. The quantitative analysis provided detailed insight into the MEW process flows within the system and assisted with the identification and selection of environmental efficiency improvements. The key learning points from conducting the analysis generated a set of guidelines to aid the analysis of manufacturing systems, using MEW process flow modelling. This paper documents the approach developed and the environmental performance improvement opportunities identified in the case facility. 链接:http://www.sciencedirect.com/science/article/pii/S0925527312000515 2. 标题:The Internet of Things: A survey • Article 出处:Computer Networks, Volume 54, Issue 15, October 2010, Pages 2787-2805 作者:Atzori, L.; Iera, A.; Morabito, G. 摘要:This paper addresses the Internet of Things. Main enabling factor of this promising paradigm is the integration of several technologies and communications solutions. Identification and tracking technologies, wired and wireless sensor and actuator networks, enhanced communication protocols (shared with the Next Generation Internet), and distributed intelligence for smart objects are just the most relevant. As one can easily imagine, any serious contribution to the advance of the Internet of Things must necessarily be the result of synergetic activities conducted in different fields of knowledge, such as telecommunications, informatics, electronics and social science. In such a complex scenario, this survey is directed to those who want to approach this complex discipline and contribute to its development. Different visions of this Internet of Things paradigm are reported and enabling technologies reviewed. What emerges is that still major issues shall be faced by the research community. The most relevant among them are addressed in details. 链接:http://www.sciencedirect.com/science/article/pii/S1389128610001568 1 3. 标 题 : Synthesis and surface engineering of iron oxide nanoparticles for biomedical applications • Review article 出处:Biomaterials, Volume 26, Issue 18, June 2005, Pages 3995-4021 作者:Gupta, A.K.; Gupta, M. 摘要:Superparamagnetic iron oxide nanoparticles (SPION) with appropriate surface chemistry have been widely used experimentally for numerous in vivo applications such as magnetic resonance imaging contrast enhancement, tissue repair, immunoassay, detoxification of biological fluids, hyperthermia, drug delivery and in cell separation, etc. All these biomedical and bioengineering applications require that these nanoparticles have high magnetization values and size smaller than 100 nm with overall narrow particle size distribution, so that the particles have uniform physical and chemical properties. In addition, these applications need special surface coating of the magnetic particles, which has to be not only non-toxic and biocompatible but also allow a targetable delivery with particle localization in a specific area. To this end, most work in this field has been done in improving the biocompatibility of the materials, but only a few scientific investigations and developments have been carried out in improving the quality of magnetic particles, their size distribution, their shape and surface in addition to characterizing them to get a protocol for the quality control of these particles. Nature of surface coatings and their subsequent geometric arrangement on the nanoparticles determine not only the overall size of the colloid but also play a significant role in biokinetics and biodistribution of nanoparticles in the body. The types of specific coating, or derivatization, for these nanoparticles depend on the end application and should be chosen by keeping a particular application in mind, whether it be aimed at inflammation response or anti-cancer agents. Magnetic nanoparticles can bind to drugs, proteins, enzymes, antibodies, or nucleotides and can be directed to an organ, tissue, or tumour using an external magnetic field or can be heated in alternating magnetic fields for use in hyperthermia. This review discusses the synthetic chemistry, fluid stabilization and surface modification of superparamagnetic iron oxide nanoparticles, as well as their use for above biomedical applications. 链接:http://www.sciencedirect.com/science/article/pii/S0142961204009317 4. 标 题 : A review on polymer nanofibers by electrospinning and their applications in nanocomposites • Article 出处:Composites Science and Technology, Volume 63, Issue 15, November 2003, Pages 2223-2253 作者:Huang, Z.-M.; Zhang, Y.-Z.; Kotaki, M.; Ramakrishna, S. 摘要:Electrospinning has been recognized as an efficient technique for the fabrication of polymer nanofibers. Various polymers have been successfully electrospun into ultrafine fibers in recent years mostly in solvent solution and some in melt form. Potential applications based on such fibers specifically their use as reinforcement in nanocomposite development have been realized. In this paper, a comprehensive review is presented on the researches and developments related to electrospun polymer nanofibers including processing, structure and property characterization, applications, and modeling and simulations. Information of those polymers together with their processing conditions for electrospinning of ultrafine fibers has been summarized in the paper. Other issues regarding the technology limitations, research challenges, and future trends are also discussed. 2 链接:http://www.sciencedirect.com/science/article/pii/S0266353803001787 5. 标题:Project management: cost, time and quality, two best guesses and a phenomenon, its time to accept other success criteria • Article 出处:International Journal of Project Management, Volume 17, Issue 6, December 1999, Pages 337-342 作者:Atkinson, Roger 摘要:This paper provides some thoughts about success criteria for IS–IT project management. Cost, time and quality (The Iron Triangle), over the last 50 years have become inextricably linked with measuring the success of project management. This is perhaps not surprising, since over the same period those criteria are usually included in the description of project management. Time and costs are at best, only guesses, calculated at a time when least is known about the project. Quality is a phenomenon, it is an emergent property of peoples different attitudes and beliefs, which often change over the development life-cycle of a project. Why has project management been so reluctant to adopt other criteria in addition to the Iron Triangle, such as stakeholder benefits against which projects can be assessed? This paper proposes a new framework to consider success criteria, The Square Route. 链接:http://www.sciencedirect.com/science/article/pii/S0263786398000696 6. 标题:Data-intensive applications, challenges, techniques and technologies: A survey on Big Data • Article 出处:Information Sciences, Volume 275, August 2014, Pages 314-347 作者:Philip Chen, C.L.; Zhang, C.Y. 摘要:It is already true that Big Data has drawn huge attention from researchers in information sciences, policy and decision makers in governments and enterprises. As the speed of information growth exceeds Moore’s Law at the beginning of this new century, excessive data is making great troubles to human beings. However, there are so much potential and highly useful values hidden in the huge volume of data. A new scientific paradigm is born as data-intensive scientific discovery (DISD), also known as Big Data problems. A large number of fields and sectors, ranging from economic and business activities to public administration, from national security to scientific researches in many areas, involve with Big Data problems. On the one hand, Big Data is extremely valuable to produce productivity in businesses and evolutionary breakthroughs in scientific disciplines, which give us a lot of opportunities to make great progresses in many fields. There is no doubt that the future competitions in business productivity and technologies will surely converge into the Big Data explorations. On the other hand, Big Data also arises with many challenges, such as difficulties in data capture, data storage, data analysis and data visualization. This paper is aimed to demonstrate a close-up view about Big Data, including Big Data applications, Big Data opportunities and challenges, as well as the state-of-the-art techniques and technologies we currently adopt to deal with the Big Data problems. We also discuss several underlying methodologies to handle the data deluge, for example, granular computing, cloud computing, bio-inspired computing, and quantum computing. 链接:http://www.sciencedirect.com/science/article/pii/S0020025514000346 3 7. 标题:A survey on security issues in service delivery models of cloud computing • Review article 出处:Journal of Network and Computer Applications, Volume 34, Issue 1, January 2011, Pages 1-11 作者:Subashini, S.; Kavitha, V. 摘要:Cloud computing is a way to increase the capacity or add capabilities dynamically without investing in new infrastructure, training new personnel, or licensing new software. It extends Information Technology’s (IT) existing capabilities. In the last few years, cloud computing has grown from being a promising business concept to one of the fast growing segments of the IT industry. But as more and more information on individuals and companies are placed in the cloud, concerns are beginning to grow about just how safe an environment it is. Despite of all the hype surrounding the cloud, enterprise customers are still reluctant to deploy their business in the cloud. Security is one of the major issues which reduces the growth of cloud computing and complications with data privacy and data protection continue to plague the market. The advent of an advanced model should not negotiate with the required functionalities and capabilities present in the current model. A new model targeting at improving features of an existing model must not risk or threaten other important features of the current model. The architecture of cloud poses such a threat to the security of the existing technologies when deployed in a cloud environment. Cloud service users need to be vigilant in understanding the risks of data breaches in this new environment. In this paper, a survey of the different security risks that pose a threat to the cloud is presented. This paper is a survey more specific to the different security issues that has emanated due to the nature of the service delivery models of a cloud computing system. 链接:http://www.sciencedirect.com/science/article/pii/S1084804510001281 8. 标题:Surface plasmon resonance sensors: review • Article 出处:Sensors and Actuators B: Chemical, Volume 54, Issue 1-2, January 1999, Pages 3-15 作者:Homola, J.; Yee, S.S.; Gauglitz, G. 摘要:Since the first application of the surface plasmon resonance (SPR) phenomenon for sensing almost two decades ago, this method has made great strides both in terms of instrumentation development and applications.

SMAs have drawn significant attention and interest in recent years in a broad range of commercial applications, due to their unique and 4 superior properties; this commercial development has been supported by fundamental and applied research studies. This work describes the attributes of SMAs that make them ideally suited to actuators in various applications, and addresses their associated limitations to clarify the design challenges faced by SMA developers. This work provides a timely review of recent SMA research and commercial applications, with over 100 state-of-the-art patents; which are categorised against relevant commercial domains and rated according to design objectives of relevance to these domains (particularly automotive, aerospace, robotic and biomedical). Although this work presents an extensive review of SMAs, other categories of SMMs are also discussed; including a historical overview, summary of recent advances and new application opportunities. 链接:http://www.sciencedirect.com/science/article/pii/S0261306913011345 10. 标题:The "real" success factors on projects • Article 出处:International Journal of Project Management, Volume 20, Issue 3, April 2002, Pages 185-190 作者:Cooke-Davies, Terry 摘要:A comprehensive answer to the question of which factors are critical to project success depends on answering three separate questions: “What factors lead to project management success?”, “What factors lead to a successful project?” and “What factors lead to consistently successful projects?” This paper draws on new empirical research from more than 70 large multi-national or national organizations to answer each of these three questions, and to identify 12 factors that are, in one way or another, critical to project success 链接:http://www.sciencedirect.com/science/article/pii/S0263786301000679 11. 标题:Wireless sensor networks: a survey • Article 出处:Computer Networks, Volume 38, Issue 4, March 2002, Pages 393-422 作者:Akyildiz, I.F.; Su, W.; Sankarasubramaniam, Y.; Cayirci, E. 摘要:This paper describes the concept of sensor networks which has been made viable by the convergence of micro-electro-mechanical systems technology, wireless communications and digital electronics.

In this work, a review has been carried out of the history of thermal energy storage with solid–liquid phase change. Three aspects have been the focus of this review: materials, heat transfer and applications. The paper 5 contains listed over 150 materials used in research as PCMs, and about 45 commercially available PCMs. The paper lists over 230 references. 链接:http://www.sciencedirect.com/science/article/pii/S1359431102001928 13. 标题:Leadership competency profiles of successful project managers • Article 出处:International Journal of Project Management, Volume 28, Issue 5, July 2010, Pages 437-448 作者:Müller, Ralf; Turner, Rodney 摘要:This study examines the leadership competency profiles of successful project managers in different types of projects. Four hundred responses to the Leadership Development Questionnaire (LDQ) were used to profile the intellectual, managerial and emotional competences (IQ, MQ and EQ, respectively) of project managers of successful projects. Differences by project type were accounted for through categorization of projects by their application type (engineering & construction, information & telecommunication technology, organizational change), complexity, importance and contract type. Results indicate high expressions of one IQ sub-dimension (i.e. critical thinking) and three EQ sub-dimensions (i.e. influence, motivation and conscientiousness) in successful managers in all types of projects. Other sub-dimensions varied by project type. Comparison was made to existing profiles for goal oriented, involving and engaging leadership styles. Implications derived are the need for practitioners to be trained in the soft factors of leadership, particular for their types of projects. Theoretical implications include the need for more transactional styles in relatively simple projects and more transformational leadership styles in complex projects. 链接:http://www.sciencedirect.com/science/article/pii/S0263786309000970 14. 标题:Exploring the value of project management: Linking Project Management Performance and Project Success • Article 出处:International Journal of Project Management 作者:Mir, Farzana Asad; Pinnington, Ashly H. 摘要:The literature on Project Management (PM) shows that, in spite of advancement in PM processes, tools and systems, project success has not significantly improved. This problem raises questions about the value and effectiveness of PM and PM systems. This paper reports a research study which tests the relationship between PM performance and project success drawing from empirical data on PM professionals working in UAE project-based organisations. Multi-dimensional frameworks are validated and used in this study to measure PM performance and project success. A total of 154 completed questionnaires were analysed. Bi-variate correlation and multiple regression tests found a positive influence of PM performance and its contributing variables on project success. Additionally, new variable relationships that have not previously been identified are explored between individual variables of PM performance and project success. 链接:http://www.sciencedirect.com/science/article/pii/S0263786313000884 15. 标题:A review on buildings energy consumption information • Article 出处:Energy and Buildings, Volume 40, Issue 3, January 2008, Pages 394-398 作者:Perez-Lombard, L.; Ortiz, J.; Pout, C. 摘要:The rapidly growing world energy use has already raised concerns over supply difficulties, 6 exhaustion of energy resources and heavy environmental impacts (ozone layer depletion, global warming, climate change, etc.). The global contribution from buildings towards energy consumption, both residential and commercial, has steadily increased reaching figures between 20% and 40% in developed countries, and has exceeded the other major sectors: industrial and transportation. Growth in population, increasing demand for building services and comfort levels, together with the rise in time spent inside buildings, assure the upward trend in energy demand will continue in the future. For this reason, energy efficiency in buildings is today a prime objective for energy policy at regional, national and international levels. Among building services, the growth in HVAC systems energy use is particularly significant (50% of building consumption and 20% of total consumption in the USA). This paper analyses available information concerning energy consumption in buildings, and particularly related to HVAC systems. Many questions arise: Is the necessary information available? Which are the main building types? What end uses should be considered in the breakdown? Comparisons between different countries are presented specially for commercial buildings. The case of offices is analysed in deeper detail. 链接:http://www.sciencedirect.com/science/article/pii/S0378778807001016 16. 标题:Scaffolds in tissue engineering bone and cartilage • Article 出处:Biomaterials, Volume 21, Issue 24, December 2000, Pages 2529-2543 作者:Hutmacher, D.W. 摘要:Musculoskeletal tissue, bone and cartilage are under extensive investigation in tissue engineering research. A number of biodegradable and bioresorbable materials, as well as scaffold designs, have been experimentally and/or clinically studied. Ideally, a scaffold should have the following characteristics: (i) three-dimensional and highly porous with an interconnected pore network for cell growth and flow transport of nutrients and metabolic waste; (ii) biocompatible and bioresorbable with a controllable degradation and resorption rate to match cell/tissue growth in vitro and/or in vivo; (iii) suitable surface chemistry for cell attachment, proliferation, and differentation and (iv) mechanical properties to match those of the tissues at the site of implantation. This paper reviews research on the tissue engineering of bone and cartilage from the polymeric scaffold point of view. 链接:http://www.sciencedirect.com/science/article/pii/S0142961200001216 17. 标题:A framework for supply chain performance measurement • Article 出处:International Journal of Production Economics, Volume 87, Issue 3, February 2004, Pages 333-347 作者:Gunasekaran, A; Patel, C; McGaughey, Ronald E 摘要:Supply chain management (SCM) has been a major component of competitive strategy to enhance organizational productivity and profitability. The literature on SCM that deals with strategies and technologies for effectively managing a supply chain is quite vast. In recent years, organizational performance measurement and metrics have received much attention from researchers and practitioners. The role of these measures and metrics in the success of an organization cannot be overstated because they affect strategic, tactical and operational planning and control. Performance measurement and metrics have an important role to play in setting objectives, evaluating performance, and determining future courses of actions. Performance measurement and metrics pertaining to SCM have not received adequate attention from 7 researchers or practitioners. We developed a framework to promote a better understanding of the importance of SCM performance measurement and metrics. Using the current literature and the results of an empirical study of selected British companies, we developed the framework presented herein, in hopes that it would stimulate more interest in this important area. 链接:http://www.sciencedirect.com/science/article/pii/S0925527303002561 18. 标题:Wireless sensor network survey • Article 出处:Computer Networks, Volume 52, Issue 12, August 2008, Pages 2292-2330 作者:Yick, J.; Mukherjee, B.; Ghosal, D. 摘要:A wireless sensor network (WSN) has important applications such as remote environmental monitoring and target tracking. This has been enabled by the availability, particularly in recent years, of sensors that are smaller, cheaper, and intelligent. These sensors are equipped with wireless interfaces with which they can communicate with one another to form a network. The design of a WSN depends significantly on the application, and it must consider factors such as the environment, the application’s design objectives, cost, hardware, and system constraints. The goal of our survey is to present a comprehensive review of the recent literature since the publication of [I.F. Akyildiz, W. Su, Y. Sankarasubramaniam, E. Cayirci, A survey on sensor networks, IEEE Communications Magazine, 2002]. Following a top-down approach, we give an overview of several new applications and then review the literature on various aspects of WSNs. We classify the problems into three different categories: (1) internal platform and underlying operating system, (2) communication protocol stack, and (3) network services, provisioning, and deployment. We review the major development in these three categories and outline new challenges. 链接:http://www.sciencedirect.com/science/article/pii/S1389128608001254 19. 标题:The project benefits of Building Information Modelling (BIM) • Article 出处:International Journal of Project Management, Pages 971-980 作者:Bryde, David; Broquetas, Martí; Volm, Jürgen Marc 摘要:Theoretical developments in Building Information Modelling (BIM) suggest that not only is it useful for geometric modelling of a building's performance but also that it can assist in the management of construction projects. The purpose of this paper is to explore the extent to which the use of BIM has resulted in reported benefits on a cross-section of construction projects. This exploration is done by collecting secondary data from 35 construction projects that utilised BIM. A set of project success criteria were generated and content analysis was used to establish the extent to which each individual project met a criterion. The most frequently reported benefit related to the cost reduction and control through the project life cycle. Significant time savings were also reported. Negative benefits were mainly focused on the use of BIM software. Cost/benefit analysis, awareness raising and education and training are important activities to address the challenges of BIM usage. 链接: http://www.sciencedirect.com/science/article/pii/S0263786312001779 20. 标题:A review of solar collectors and thermal energy storage in solar thermal applications • Article 出处:Applied Energy, Volume 104, April 2013, Pages 538-553 作者:Tian, Y.; Zhao, C.Y. 8 摘要:Thermal applications are drawing increasing attention in the solar energy research field, due to their high performance in energy storage density and energy conversion efficiency. In these applications, solar collectors and thermal energy storage systems are the two core components. This paper focuses on the latest developments and advances in solar thermal applications, providing a review of solar collectors and thermal energy storage systems. Various types of solar collectors are reviewed and discussed, including both non-concentrating collectors (low temperature applications) and concentrating collectors (high temperature applications). These are studied in terms of optical optimisation, heat loss reduction, heat recuperation enhancement and different sun-tracking mechanisms. Various types of thermal energy storage systems are also reviewed and discussed, including sensible heat storage, latent heat storage, chemical storage and cascaded storage. They are studied in terms of design criteria, material selection and different heat transfer enhancement technologies. Last but not least, existing and future solar power stations are overviewed. 链接:http://www.sciencedirect.com/science/article/pii/S0306261912008549 21. 标题:Sustainable supply chains: An introduction • Article 出处:Journal of Operations Management, Volume 25, Issue 6, November 2007, Pages 1075-1082 作者:Linton, Jonathan D.; Klassen, Robert; Jayaraman, Vaidyanathan 摘要:Consideration is given to the convergence of supply chains and sustainability. In doing so, the focus on environmental management and operations is moved from local optimization of environmental factors to consideration of the entire supply chain during the production, consumption, customer service and post-disposal disposition of products. This is a critical and timely topic that captures increasing concerns over sustainability, whether driven by current legislation, public interest, or competitive opportunity. As such, sustainable development is a rich area for academic research that is still in its infancy and has the potential to affect future government policy, current production operations, and identify new business models. This paper provides a background to better understand current trends in this multidisciplinary field that intersect with operations management, and the research opportunities and challenges it presents. 链接:http://www.sciencedirect.com/science/article/pii/S0272696307000149 22. 标题:Trends in big data analytics • Article 出处:Journal of Parallel and Distributed Computing, Volume 74, Issue 7, July 2014, Pages 2561-2573 作者:Kambatla, K.; Kollias, G.; Kumar, V.; Grama, A. 摘要:One of the major applications of future generation parallel and distributed systems is in big-data analytics. Data repositories for such applications currently exceed exabytes and are rapidly increasing in size. Beyond their sheer magnitude, these datasets and associated applications’ considerations pose significant challenges for method and software development. Datasets are often distributed and their size and privacy considerations warrant distributed techniques. Data often resides on platforms with widely varying computational and network capabilities. Considerations of fault-tolerance, security, and access control are critical in many applications (Dean and Ghemawat, 2004; Apache hadoop). Analysis tasks often have hard deadlines, and data quality is a major concern in yet other applications. For most emerging applications, data-driven models and methods, capable of operating at scale, are as-yet unknown. 9 Even when known methods can be scaled, validation of results is a major issue. Characteristics of hardware platforms and the software stack fundamentally impact data analytics. In this article, we provide an overview of the state-of-the-art and focus on emerging trends to highlight the hardware, software, and application landscape of big-data analytics. 链接:http://www.sciencedirect.com/science/article/pii/S0743731514000057 23. 标题:Hydrogels for tissue engineering: scaffold design variables and applications • Review article 出处:Biomaterials, Volume 24, Issue 24, November 2003, Pages 4337-4351 作者:Drury, J.L.; Mooney, D.J. 摘要:Polymer scaffolds have many different functions in the field of tissue engineering. They are applied as space filling agents, as delivery vehicles for bioactive molecules, and as three-dimensional structures that organize cells and present stimuli to direct the formation of a desired tissue. Much of the success of scaffolds in these roles hinges on finding an appropriate material to address the critical physical, mass transport, and biological design variables inherent to each application. Hydrogels are an appealing scaffold material because they are structurally similar to the extracellular matrix of many tissues, can often be processed under relatively mild conditions, and may be delivered in a minimally invasive manner. Consequently, hydrogels have been utilized as scaffold materials for drug and growth factor delivery, engineering tissue replacements, and a variety of other applications. 链接:http://www.sciencedirect.com/science/article/pii/S0142961203003405 24. 标题:Advances in the science and technology of carbon nanotubes and their composites: a review • Article 出处:Composites Science and Technology, Volume 61, Issue 13, October 2001, Pages 1899-1912 作者:Thostenson, E.T.; Ren, Z.; Chou, T.-W. 摘要:Since their first observation nearly a decade ago by Iijima (Iijima S. Helical microtubules of graphitic carbon Nature. 1991; 354:56–8), carbon nanotubes have been the focus of considerable research. Numerous investigators have since reported remarkable physical and mechanical properties for this new form of carbon. From unique electronic properties and a thermal conductivity higher than diamond to mechanical properties where the stiffness, strength and resilience exceeds any current material, carbon nanotubes offer tremendous opportunities for the development of fundamentally new material systems. In particular, the exceptional mechanical properties of carbon nanotubes, combined with their low density, offer scope for the development of nanotube-reinforced composite materials. The potential for nanocomposites reinforced with carbon tubes having extraordinary specific stiffness and strength represent tremendous opportunity for application in the 21st century. This paper provides a concise review of recent advances in carbon nanotubes and their composites.

Nelson, S.G. Winter, An Evolutionary Theory of Economic Change, Harvard University Press, Cambridge, MA, 1982]. This paper examines the effects of three contextual factors, plant size, plant age and unionization status, on the likelihood of implementing 22 manufacturing practices that are key facets of lean production systems. Further, we postulate four “bundles” of inter-related and internally consistent practices; these are just-in-time (JIT), total quality management (TQM), total preventive maintenance (TPM), and human resource management (HRM). We empirically validate our bundles and investigate their effects on operational performance. The study sample uses data from IndustryWeek’s Census of Manufacturers. The evidence provides strong support for the influence of plant size on lean implementation, whereas the influence of unionization and plant age is less pervasive than conventional wisdom suggests. The results also indicate that lean bundles contribute substantially to the operating performance of plants, and explain about 23% of the variation in operational performance after accounting for the effects of industry and contextual factors. 链接:http://www.sciencedirect.com/science/article/pii/S0272696302001080 二、Elsevier Science Direct Top 25 (化学类) (来源:http://www.sciencedirect.com/) 1. 标题:UV-assisted in situ synthesis of silver nanoparticles on silk fibers for antibacterial applications • Article 出处:Colloids and Surfaces A: Physicochemical and Engineering Aspects, Volume 447, April 2014, Pages 1-7 作者:Lu, Z.; Meng, M.; Jiang, Y.; Xie, J. 摘要:To overcome the bacteria-caused degradation of silk, an ultraviolet light (UV)-assisted in situ synthesis approach is developed to immobilize silver nanoparticles (AgNPs) on degummed silk fibers for antibacterial applications. Results show that AgNPs with excellent crystalline structures are efficiently attached on the silk surface in an irradiation time-dependent manner. The immobilization of AgNPs could greatly delay the thermal degradation of silk. The antibacterial activity of the AgNPs-coated silk is evaluated by the growth curve of bacteria, zone of inhibition and dual staining assays, clearly demonstrating its bacterial growth inhibition ability and bactericidal effects. This work offers potentials to produce specific AgNPs-coated antimicrobial silk for various applications in textile industry. 链接:http://www.sciencedirect.com/science/article/pii/S0927775714001034 2. 标题:ZFN, TALEN, and CRISPR/Cas-based methods for genome engineering • Review article 出处:Trends in Biotechnology, Volume 31, Issue 7, July 2013, Pages 397-405 作者:Gaj, T.; Gersbach, C.A.; Barbas, C.F. 摘要:Zinc-finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs) 11 comprise a powerful class of tools that are redefining the boundaries of biological research. These chimeric nucleases are composed of programmable, sequence-specific DNA-binding modules linked to a nonspecific DNA cleavage domain. ZFNs and TALENs enable a broad range of genetic modifications by inducing DNA double-strand breaks that stimulate error-prone nonhomologous end joining or homology-directed repair at specific genomic locations. Here, we review achievements made possible by site-specific nuclease technologies and discuss applications of these reagents for genetic analysis and manipulation. In addition, we highlight the therapeutic potential of ZFNs and TALENs and discuss future prospects for the field, including the emergence of clustered regulatory interspaced short palindromic repeat (CRISPR)/Cas-based RNA-guided DNA endonucleases. 链接:http://www.sciencedirect.com/science/article/pii/S0167779913000875 3. 标题:Hydrolysis of lignocellulosic materials for ethanol production: a review • Article 出处:Bioresource Technology, Volume 83, Issue 1, May 2002, Pages 1-11 作者:Sun, Y.; Cheng, J. 摘要:Lignocellulosic biomass can be utilized to produce ethanol, a promising alternative energy source for the limited crude oil. There are mainly two processes involved in the conversion: hydrolysis of cellulose in the lignocellulosic biomass to produce reducing sugars, and fermentation of the sugars to ethanol. The cost of ethanol production from lignocellulosic materials is relatively high based on current technologies, and the main challenges are the low yield and high cost of the hydrolysis process. Considerable research efforts have been made to improve the hydrolysis of lignocellulosic materials. Pretreatment of lignocellulosic materials to remove lignin and hemicellulose can significantly enhance the hydrolysis of cellulose. Optimization of the cellulase enzymes and the enzyme loading can also improve the hydrolysis. Simultaneous saccharification and fermentation effectively removes glucose, which is an inhibitor to cellulase activity, thus increasing the yield and rate of cellulose hydrolysis. 链接:http://www.sciencedirect.com/science/article/pii/S0960852401002127 4. 标 题 : Synthesis and surface engineering of iron oxide nanoparticles for biomedical applications • Review article 出处:Biomaterials, Volume 26, Issue 18, June 2005, Pages 3995-4021 作者:Gupta, A.K.; Gupta, M. 摘要:Superparamagnetic iron oxide nanoparticles (SPION) with appropriate surface chemistry have been widely used experimentally for numerous in vivo applications such as magnetic resonance imaging contrast enhancement, tissue repair, immunoassay, detoxification of biological fluids, hyperthermia, drug delivery and in cell separation, etc. All these biomedical and bioengineering applications require that these nanoparticles have high magnetization values and size smaller than 100 nm with overall narrow particle size distribution, so that the particles have uniform physical and chemical properties. In addition, these applications need special surface coating of the magnetic particles, which has to be not only non-toxic and biocompatible but also allow a targetable delivery with particle localization in a specific area. To this end, most work in this field has been done in improving the biocompatibility of the materials, but only a few scientific investigations and developments have been carried out in improving the quality of magnetic particles, their size distribution, their shape and surface in addition to characterizing 12 them to get a protocol for the quality control of these particles. Nature of surface coatings and their subsequent geometric arrangement on the nanoparticles determine not only the overall size of the colloid but also play a significant role in biokinetics and biodistribution of nanoparticles in the body. The types of specific coating, or derivatization, for these nanoparticles depend on the end application and should be chosen by keeping a particular application in mind, whether it be aimed at inflammation response or anti-cancer agents. Magnetic nanoparticles can bind to drugs, proteins, enzymes, antibodies, or nucleotides and can be directed to an organ, tissue, or tumour using an external magnetic field or can be heated in alternating magnetic fields for use in hyperthermia. This review discusses the synthetic chemistry, fluid stabilization and surface modification of superparamagnetic iron oxide nanoparticles, as well as their use for above biomedical applications. 链接:http://www.sciencedirect.com/science/article/pii/S0142961204009317 5. 标题:Biodiesel production: a review • Article 出处:Bioresource Technology, Volume 70, Issue 1, October 1999, Pages 1-15 作者:Ma, F.; Hanna, M.A. 摘要:Biodiesel has become more attractive recently because of its environmental benefits and the fact that it is made from renewable resources. The cost of biodiesel, however, is the main hurdle to commercialization of the product. The used cooking oils are used as raw material, adaption of continuous transesterification process and recovery of high quality glycerol from biodiesel by-product (glycerol) are primary options to be considered to lower the cost of biodiesel. There are four primary ways to make biodiesel, direct use and blending, microemulsions, thermal cracking (pyrolysis) and transesterification. The most commonly used method is transesterification of vegetable oils and animal fats. The transesterification reaction is affected by molar ratio of glycerides to alcohol, catalysts, reaction temperature, reaction time and free fatty acids and water content of oils or fats. The mechanism and kinetics of the transesterification show how the reaction occurs and progresses. The processes of transesterification and its downstream operations are also addressed. 链接:http://www.sciencedirect.com/science/article/pii/S0960852499000255 6. 标题:Biodiesel from microalgae • Review article 出处:Biotechnology Advances, Volume 25, Issue 3, May 2007, Pages 294-306 作者:Chisti, Y. 摘要:Continued use of petroleum sourced fuels is now widely recognized as unsustainable because of depleting supplies and the contribution of these fuels to the accumulation of carbon dioxide in the environment. Renewable, carbon neutral, transport fuels are necessary for environmental and economic sustainability. Biodiesel derived from oil crops is a potential renewable and carbon neutral alternative to petroleum fuels. Unfortunately, biodiesel from oil crops, waste cooking oil and animal fat cannot realistically satisfy even a small fraction of the existing demand for transport fuels. As demonstrated here, microalgae appear to be the only source of renewable biodiesel that is capable of meeting the global demand for transport fuels. Like plants, microalgae use sunlight to produce oils but they do so more efficiently than crop plants. Oil productivity of many microalgae greatly exceeds the oil productivity of the best producing oil crops. Approaches for making microalgal biodiesel economically competitive with 13 petrodiesel are discussed. 链接:http://www.sciencedirect.com/science/article/pii/S0734975007000262 7. 标题:Event extraction for systems biology by text mining the literature • Review article 出处:Trends in Biotechnology, Volume 28, Issue 7, July 2010, Pages 381-390 作者:Ananiadou, S.; Pyysalo, S.; Tsujii, J.; Kell, D.B. 摘要:Systems biology recognizes in particular the importance of interactions between biological components and the consequences of these interactions.

A distinction is made between the film-forming techniques that are used currently such as spincoating, doctor blading and casting and the, from a processing point of view, more desirable film-forming techniques such as slot-die coating, gravure coating, knife-over-edge coating, off-set coating, spray coating and printing techniques such as ink jet printing, pad printing and screen printing. The former are used almost exclusively and are not suited for high-volume production whereas the latter are highly suited, but little explored in the context of polymer solar cells. A further distinction is made between printing and coating when a film is formed. The entire process leading to polymer solar cells is broken down into the individual steps and the available techniques and materials for each step are described with focus on the particular advantages and disadvantages associated with each case. 链接:http://www.sciencedirect.com/science/article/pii/S0927024808003486 12. 标题:Scaffolds in tissue engineering bone and cartilage • Article 出处:Biomaterials, Volume 21, Issue 24, December 2000, Pages 2529-2543 作者:Hutmacher, D.W. 摘要:Musculoskeletal tissue, bone and cartilage are under extensive investigation in tissue engineering research. A number of biodegradable and bioresorbable materials, as well as scaffold designs, have been experimentally and/or clinically studied. Ideally, a scaffold should have the following characteristics: (i) three-dimensional and highly porous with an interconnected pore network for cell growth and flow transport of nutrients and metabolic waste; (ii) biocompatible and bioresorbable with a controllable degradation and resorption rate to match cell/tissue growth in vitro and/or in vivo; (iii) suitable surface chemistry for cell attachment, proliferation, and differentation and (iv) mechanical properties to match those of the tissues at the site of implantation. This paper reviews research on the tissue engineering of bone and cartilage from the polymeric scaffold point of view. 15 链接:http://www.sciencedirect.com/science/article/pii/S0142961200001216 13. 标题:Silver nanoparticles as a new generation of antimicrobials • Review article 出处:Biotechnology Advances, Volume 27, Issue 1, January 2009, Pages 76-83 作者:Rai, M.; Yadav, A.; Gade, A. 摘要:Silver has been in use since time immemorial in the form of metallic silver, silver nitrate, silver sulfadiazine for the treatment of burns, wounds and several bacterial infections. But due to the emergence of several antibiotics the use of these silver compounds has been declined remarkably. Nanotechnology is gaining tremendous impetus in the present century due to its capability of modulating metals into their nanosize, which drastically changes the chemical, physical and optical properties of metals. Metallic silver in the form of silver nanoparticles has made a remarkable comeback as a potential antimicrobial agent. The use of silver nanoparticles is also important, as several pathogenic bacteria have developed resistance against various antibiotics. Hence, silver nanoparticles have emerged up with diverse medical applications ranging from silver based dressings, silver coated medicinal devices, such as nanogels, nanolotions, etc. 链接:http://www.sciencedirect.com/science/article/pii/S0734975008000918 14. 标题:Dye-sensitized solar cells • Review article 出处:Journal of Photochemistry and Photobiology C: Photochemistry Reviews, Volume 4, Issue 2, October 2003, Pages 145-153 作者:Gratzel, M. 摘要:The dye-sensitized solar cells (DSC) provides a technically and economically credible alternative concept to present day p–n junction photovoltaic devices. In contrast to the conventional systems where the semiconductor assume both the task of light absorption and charge carrier transport the two functions are separated here. Light is absorbed by a sensitizer, which is anchored to the surface of a wide band semiconductor. Charge separation takes place at the interface via photo-induced electron injection from the dye into the conduction band of the solid. Carriers are transported in the conduction band of the semiconductor to the charge collector. The use of sensitizers having a broad absorption band in conjunction with oxide films of nanocrstalline morphology permits to harvest a large fraction of sunlight. Nearly quantitative conversion of incident photon into electric current is achieved over a large spectral range extending from the UV to the near IR region. Overall solar (standard AM 1.5) to current conversion efficiencies (IPCE) over 10% have been reached. There are good prospects to produce these cells at lower cost than conventional devices. Here we present the current state of the field, discuss new concepts of the dye-sensitized nanocrystalline solar cell (DSC) including heterojunction variants and analyze the perspectives for the future development of the technology. 链接:http://www.sciencedirect.com/science/article/pii/S1389556703000261 15. 标题:Pretreatment technologies for an efficient bioethanol production process based on enzymatic hydrolysis: A review • Article 出处:Bioresource Technology, Volume 101, Issue 13, July 2010, Pages 4851-4861 作者:Alvira, P.; Tomas-Pejo, E.; Ballesteros, M.; Negro, M.J. 摘要:Biofuel produced from lignocellulosic materials, so-called second generation bioethanol shows energetic, economic and environmental advantages in comparison to bioethanol from starch 16 or sugar. However, physical and chemical barriers caused by the close association of the main components of lignocellulosic biomass, hinder the hydrolysis of cellulose and hemicellulose to fermentable sugars. The main goal of pretreatment is to increase the enzyme accessibility improving digestibility of cellulose. Each pretreatment has a specific effect on the cellulose, hemicellulose and lignin fraction thus, different pretreatment methods and conditions should be chosen according to the process configuration selected for the subsequent hydrolysis and fermentation steps. This paper reviews the most interesting technologies for ethanol production from lignocellulose and it points out several key properties that should be targeted for low-cost and advanced pretreatment processes. 链接:http://www.sciencedirect.com/science/article/pii/S0960852409015983 16. 标题:Arsenic removal from water/wastewater using adsorbents-A critical review • Review article 出处:Journal of Hazardous Materials, Volume 142, Issue 1-2, April 2007, Pages 1-53 作者:Mohan, D.; Pittman, C.U. 摘要:Arsenic's history in science, medicine and technology has been overshadowed by its notoriety as a poison in homicides. Arsenic is viewed as being synonymous with toxicity. Dangerous arsenic concentrations in natural waters is now a worldwide problem and often referred to as a 20th–21st century calamity. High arsenic concentrations have been reported recently from the USA, China, Chile, Bangladesh, Taiwan, Mexico, Argentina, Poland, Canada, Hungary, Japan and India. Among 21 countries in different parts of the world affected by groundwater arsenic contamination, the largest population at risk is in Bangladesh followed by West Bengal in India. Existing overviews of arsenic removal include technologies that have traditionally been used (oxidation, precipitation/coagulation/membrane separation) with far less attention paid to adsorption. No previous review is available where readers can get an overview of the sorption capacities of both available and developed sorbents used for arsenic remediation together with the traditional remediation methods. We have incorporated most of the valuable available literature on arsenic remediation by adsorption (∼600 references). Existing purification methods for drinking water; wastewater; industrial effluents, and technological solutions for arsenic have been listed. Arsenic sorption by commercially available carbons and other low-cost adsorbents are surveyed and critically reviewed and their sorption efficiencies are compared. Arsenic adsorption behavior in presence of other impurities has been discussed. Some commercially available adsorbents are also surveyed. An extensive table summarizes the sorption capacities of various adsorbents. Some low-cost adsorbents are superior including treated slags, carbons developed from agricultural waste (char carbons and coconut husk carbons), biosorbents (immobilized biomass, orange juice residue), goethite and some commercial adsorbents, which include resins, gels, silica, treated silica tested for arsenic removal come out to be superior. Immobilized biomass adsorbents offered outstanding performances. Desorption of arsenic followed by regeneration of sorbents has been discussed. Strong acids and bases seem to be the best desorbing agents to produce arsenic concentrates. Arsenic concentrate treatment and disposal obtained is briefly addressed. This issue is very important but much less discussed. 链接:http://www.sciencedirect.com/science/article/pii/S0304389407000349 17 17. 标题:Applications of nanotechnology in food packaging and food safety: Barrier materials, antimicrobials and sensors • Article 出处:Journal of Colloid and Interface Science, Volume 363, Issue 1, November 2011, Pages 1-24 作者:Duncan, T.V. 摘要:In this article, several applications of nanomaterials in food packaging and food safety are reviewed, including: polymer/clay nanocomposites as high barrier packaging materials, silver nanoparticles as potent antimicrobial agents, and nanosensors and nanomaterial-based assays for the detection of food-relevant analytes (gasses, small organic molecules and food-borne pathogens). In addition to covering the technical aspects of these topics, the current commercial status and understanding of health implications of these technologies are also discussed. These applications were chosen because they do not involve direct addition of nanoparticles to consumed foods, and thus are more likely to be marketed to the public in the short term. 链接:http://www.sciencedirect.com/science/article/pii/S0021979711008642 18. 标题:Titanium dioxide photocatalysis • Review article 出处:Journal of Photochemistry and Photobiology C: Photochemistry Reviews, Volume 1, Issue 1, June 2000, Pages 1-21 作者:Fujishima, A.; Rao, T.N.; Tryk, D.A. 摘要:Scientific studies on photocatalysis started about two and a half decades ago.

The development of new materials, however, is strongly required to provide enhanced performances with respect to the photocatalytic properties and to find new uses for TiO2 photocatalysis. In this review, recent developments in the area of TiO2 photocatalysis research, in terms of new materials from a structural design perspective, have been summarized. The dimensionality associated with the structure of a TiO2 material can affect its properties and functions, including its photocatalytic performance, and also more specifically its surface area, adsorption, reflectance, adhesion, and carrier transportation properties. We provide a brief introduction to the current situation in TiO2 photocatalysis, and describe structurally controlled TiO2 photocatalysts which can be classified into zero-, one-, two-, and three-dimensional structures. Furthermore, novel applications of TiO2 surfaces for the fabrication of wettability patterns and for printing are discussed. 链接:http://www.sciencedirect.com/science/article/pii/S1389556712000421 18 20. 标题:Recombinant protein expression in Escherichia coli • Review article 出处:Current Opinion in Biotechnology, Volume 10, Issue 5, October 1999, Pages 411-421 作者:Baneyx, F. 摘要:Escherichia coli is one of the most widely used hosts for the production of heterologous proteins and its genetics are far better characterized than those of any other microorganism.

Electrospinning, an electrostatic fiber fabrication technique has evinced more interest and attention in recent years due to its versatility and potential for applications in diverse fields. The notable applications include in tissue engineering, biosensors, filtration, wound dressings, drug delivery, and enzyme immobilization. The nanoscale fibers are generated by the application of strong electric field on polymer solution or melt. The non-wovens nanofibrous mats produced by this technique mimics extracellular matrix components much closely as compared to the conventional techniques. The sub-micron range spun fibers produced by this process, offer various advantages like high surface area to volume ratio, tunable porosity and the ability to manipulate nanofiber composition in order to get desired properties and function. Over the years, more than 200 polymers have been electropun for various applications and the number is still increasing gradually with time. With these in perspectives, we aim to present in this review, an overview of the electrospinning technique with its promising advantages and potential applications. We have discussed the electrospinning theory, spinnable polymers, parameters (solution and processing), which significantly affect the fiber morphology, solvent properties and melt electrospinning (alternative to solution electrospinning). Finally, we have focused on varied applications of electrospun fibers in different fields and concluded with the future prospects of this efficient technology. 链接:http://www.sciencedirect.com/science/article/pii/S0734975010000066 22. 标题:Hydrogels for tissue engineering: scaffold design variables and applications • Review article 出处:Biomaterials, Volume 24, Issue 24, November 2003, Pages 4337-4351 作者:Drury, J.L.; Mooney, D.J. 摘要:Polymer scaffolds have many different functions in the field of tissue engineering. They are applied as space filling agents, as delivery vehicles for bioactive molecules, and as three-dimensional structures that organize cells and present stimuli to direct the formation of a desired tissue. Much of the success of scaffolds in these roles hinges on finding an appropriate material to address the critical physical, mass transport, and biological design variables inherent to each application. Hydrogels are an appealing scaffold material because they are structurally similar to the extracellular matrix of many tissues, can often be processed under relatively mild 19 conditions, and may be delivered in a minimally invasive manner. Consequently, hydrogels have been utilized as scaffold materials for drug and growth factor delivery, engineering tissue replacements, and a variety of other applications. 链接:http://www.sciencedirect.com/science/article/pii/S0142961203003405 23. 标题:Inhibition of anaerobic digestion process: A review • Review article 出处:Bioresource Technology, Volume 99, Issue 10, July 2008, Pages 4044-4064 作者:Chen, Y.; Cheng, J.J.; Creamer, K.S. 摘要:Anaerobic digestion is an attractive waste treatment practice in which both pollution control and energy recovery can be achieved. Many agricultural and industrial wastes are ideal candidates for anaerobic digestion because they contain high levels of easily biodegradable materials. Problems such as low methane yield and process instability are often encountered in anaerobic digestion, preventing this technique from being widely applied. A wide variety of inhibitory substances are the primary cause of anaerobic digester upset or failure since they are present in substantial concentrations in wastes. Considerable research efforts have been made to identify the mechanism and the controlling factors of inhibition. This review provides a detailed summary of the research conducted on the inhibition of anaerobic processes. The inhibitors commonly present in anaerobic digesters include ammonia, sulfide, light metal ions, heavy metals, and organics. Due to the difference in anaerobic inocula, waste composition, and experimental methods and conditions, literature results on inhibition caused by specific toxicants vary widely. Co-digestion with other waste, adaptation of microorganisms to inhibitory substances, and incorporation of methods to remove or counteract toxicants before anaerobic digestion can significantly improve the waste treatment efficiency. 链接:http://www.sciencedirect.com/science/article/pii/S0960852407001563 24. 标题:Click hydrogels, microgels and nanogels: Emerging platforms for drug delivery and tissue engineering • Review article 出处:Biomaterials, Volume 35, Issue 18, June 2014, Pages 4969-4985 作者:Jiang, Y.; Chen, J.; Deng, C.; Suuronen, E.J.; Zhong, Z. 摘要:Hydrogels, microgels and nanogels have emerged as versatile and viable platforms for sustained protein release, targeted drug delivery, and tissue engineering due to excellent biocompatibility, a microporous structure with tunable porosity and pore size, and dimensions spanning from human organs, cells to viruses. In the past decade, remarkable advances in hydrogels, microgels and nanogels have been achieved with click chemistry. It is a most promising strategy to prepare gels with varying dimensions owing to its high reactivity, superb selectivity, and mild reaction conditions. In particular, the recent development of copper-free click chemistry such as strain-promoted azide-alkyne cycloaddition, radical mediated thiol-ene chemistry, Diels–Alder reaction, tetrazole-alkene photo-click chemistry, and oxime reaction renders it possible to form hydrogels, microgels and nanogels without the use of potentially toxic catalysts or immunogenic enzymes that are commonly required. Notably, unlike other chemical approaches, click chemistry owing to its unique bioorthogonal feature does not interfere with encapsulated bioactives such as living cells, proteins and drugs and furthermore allows versatile preparation of micropatterned biomimetic hydrogels, functional microgels and nanogels. In this review, recent exciting developments in click hydrogels, microgels and nanogels, as well as their biomedical 20 applications such as controlled protein and drug release, tissue engineering, and regenerative medicine are presented and discussed. 链接:http://www.sciencedirect.com/science/article/pii/S014296121400221X 25. 标题:Silver nanoparticles: Green synthesis and their antimicrobial activities • Review article 出处:Advances in Colloid and Interface Science, Volume 145, Issue 1-2, January 2009, Pages 83-96 作者:Sharma, V.K.; Yngard, R.A.; Lin, Y. 摘要:This review presents an overview of silver nanoparticles (Ag NPs) preparation by green synthesis approaches that have advantages over conventional methods involving chemical agents associated with environmental toxicity. Green synthetic methods include mixed-valence polyoxometallates, polysaccharide, Tollens, irradiation, and biological. The mixed-valence polyoxometallates method was carried out in water, an environmentally-friendly solvent. Solutions of AgNO3 containing glucose and starch in water gave starch-protected Ag NPs, which could be integrated into medical applications. Tollens process involves the reduction of Ag(NH3)2+ by saccharides forming Ag NP films with particle sizes from 50–200 nm, Ag hydrosols with particles in the order of 20–50 nm, and Ag colloid particles of different shapes. The reduction of Ag(NH3)2+ by HTAB (n-hexadecyltrimethylammonium bromide) gave Ag NPs of different morphologies: cubes, triangles, wires, and aligned wires. Ag NPs synthesis by irradiation of Ag+ ions does not involve a reducing agent and is an appealing procedure. Eco-friendly bio-organisms in plant extracts contain proteins, which act as both reducing and capping agents forming stable and shape-controlled Ag NPs. The synthetic procedures of polymer-Ag and TiO2–Ag NPs are also given. Both Ag NPs and Ag NPs modified by surfactants or polymers showed high antimicrobial activity against Gram-positive and Gram-negative bacteria. The mechanism of the Ag NP bactericidal activity is discussed in terms of Ag NP interaction with the cell membranes of bacteria. Silver-containing filters are shown to have antibacterial properties in water and air purification. Finally, human and environmental implications of Ag NPs to the ecology of aquatic environment are briefly discussed. 链接:http://www.sciencedirect.com/science/article/pii/S0001868608001449 三、IEL Top25 (来源:http://ieeexplore.ieee.org/) 1.标题:Data mining with big data 作者:Xindong Wu ; Xingquan Zhu ; Gong-Qing Wu ; Wei Ding 出处:Knowledge and Data Engineering, IEEE Transactions on Volume: 26 Issue: 1 Date : Jan. 2014 Page(s): 97 - 107 DOI: 10.1109/TKDE.2013.109 摘要:Big Data concern large-volume, complex, growing data sets with multiple, autonomous sources.

The term big data was coined to capture the meaning of this emerging trend. In addition to its sheer volume, big data also exhibits other unique characteristics as compared with traditional data. For instance, big data is commonly unstructured and require more real-time analysis. This development calls for new system architectures for data acquisition, transmission, storage, and large-scale data processing mechanisms. In this paper, we present a literature survey and system tutorial for big data analytics platforms, aiming to provide an overall picture for nonexpert readers and instill a do-it-yourself spirit for advanced audiences to customize their own big-data solutions. First, we present the definition of big data and discuss big data challenges. Next, we present a systematic framework to decompose big data systems into four sequential modules, namely data generation, data acquisition, data storage, and data analytics. These four modules form a big data value chain. Following that, we present a detailed survey of numerous approaches and mechanisms from research and industry communities. In addition, we present the prevalent Hadoop framework for addressing big data challenges. Finally, we outline several evaluation benchmarks and potential research directions for big data systems. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6842585 3.标题:Cellular architecture and key technologies for 5G wireless communication networks 作者:Cheng-Xiang Wang ; Haider, F. ; Xiqi Gao ; Xiao-Hu You ; Yang Yang ; Dongfeng Yuan ; Aggoune, H. ; Haas, H. ; Fletcher, S. ; Hepsaydir, E. 出处:Communications Magazine, IEEE Volume: 52 Issue: 2 Date : February 2014 Page(s): 122 - 130 DOI: 10.1109/MCOM.2014.6736752 摘要:The fourth generation wireless communication systems have been deployed or are soon to be deployed in many countries. However, with an explosion of wireless mobile devices and services, there are still some challenges that cannot be accommodated even by 4G, such as the spectrum crisis and high energy consumption. Wireless system designers have been facing the continuously increasing demand for high data rates and mobility required by new wireless 22 applications and therefore have started research on fifth generation wireless systems that are expected to be deployed beyond 2020. In this article, we propose a potential cellular architecture that separates indoor and outdoor scenarios, and discuss various promising technologies for 5G wireless communication systems, such as massive MIMO, energy-efficient communications, cognitive radio networks, and visible light communications. Future challenges facing these potential technologies are also discussed. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6736752 4.标题:Massive MIMO for next generation wireless systems 作者:Larsson, E. ; Edfors, O. ; Tufvesson, F. ; Marzetta, T. 出处:Communications Magazine, IEEE Volume: 52 Issue: 2 Date : February 2014 Page(s): 186 - 195 DOI: 10.1109/MCOM.2014.6736761 摘要:Multi-user MIMO offers big advantages over conventional point-to-point MIMO: it works with cheap single-antenna terminals, a rich scattering environment is not required, and resource allocation is simplified because every active terminal utilizes all of the time-frequency bins. However, multi-user MIMO, as originally envisioned, with roughly equal numbers of service antennas and terminals and frequency-division duplex operation, is not a scalable technology. Massive MIMO (also known as large-scale antenna systems, very large MIMO, hyper MIMO, full-dimension MIMO, and ARGOS) makes a clean break with current practice through the use of a large excess of service antennas over active terminals and time-division duplex operation. Extra antennas help by focusing energy into ever smaller regions of space to bring huge improvements in throughput and radiated energy efficiency. Other benefits of massive MIMO include extensive use of inexpensive low-power components, reduced latency, simplification of the MAC layer, and robustness against intentional jamming. The anticipated throughput depends on the propagation environment providing asymptotically orthogonal channels to the terminals, but so far experiments have not disclosed any limitations in this regard. While massive MIMO renders many traditional research problems irrelevant, it uncovers entirely new problems that urgently need attention: the challenge of making many low-cost low-precision components that work effectively together, acquisition and synchronization for newly joined terminals, the exploitation of extra degrees of freedom provided by the excess of service antennas, reducing internal power consumption to achieve total energy efficiency reductions, and finding new deployment scenarios. This article presents an overview of the massive MIMO concept and contemporary research on the topic. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6736752 5.标题:What Will 5G Be? 作者:Andrews, J.G. ; Buzzi, S. ; Wan Choi ; Hanly, S.V. ; Lozano, A. ; Soong, A.C.K. ; Zhang, J.C. 出处:Selected Areas in Communications, IEEE Journal on Volume: 32 Issue: 6 Date : June 2014 Page(s): 1065 - 1082 DOI: 10.1109/JSAC.2014.2328098 摘要:What will 5G be? What it will not be is an incremental advance on 4G. The previous four 23 generations of cellular technology have each been a major paradigm shift that has broken backward compatibility. Indeed, 5G will need to be a paradigm shift that includes very high carrier frequencies with massive bandwidths, extreme base station and device densities, and unprecedented numbers of antennas. However, unlike the previous four generations, it will also be highly integrative: tying any new 5G air interface and spectrum together with LTE and WiFi to provide universal high-rate coverage and a seamless user experience. To support this, the core network will also have to reach unprecedented levels of flexibility and intelligence, spectrum regulation will need to be rethought and improved, and energy and cost efficiencies will become even more critical considerations. This paper discusses all of these topics, identifying key challenges for future research and preliminary 5G standardization activities, while providing a comprehensive overview of the current literature, and in particular of the papers appearing in this special issue. 链接: http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6824752 6.标题:Millimeter Wave Mobile Communications for 5G Cellular: It Will Work! 作者:Rappaport, T.S. ; Shu Sun ; Mayzus, R. ; Hang Zhao ; Azar, Y. ; Wang, K. ; Wong, G.N. ; Schulz, J.K. ; Samimi, M. ; Gutierrez, F. 出处:Access, IEEE Volume: 1 Date : 2013 Page(s): 335 - 349 DOI: 10.1109/ACCESS.2013.2260813 摘要:The global bandwidth shortage facing wireless carriers has motivated the exploration of the underutilized millimeter wave (mm-wave) frequency spectrum for future broadband cellular communication networks. There is, however, little knowledge about cellular mm-wave propagation in densely populated indoor and outdoor environments. Obtaining this information is vital for the design and operation of future fifth generation cellular networks that use the mm-wave spectrum. In this paper, we present the motivation for new mm-wave cellular systems, methodology, and hardware for measurements and offer a variety of measurement results that show 28 and 38 GHz frequencies can be used when employing steerable directional antennas at base stations and mobile devices. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6824752 7. 标题:Image Quality Assessment for Fake Biometric Detection: Application to Iris, Fingerprint, and Face Recognition 作者:Galbally, J. ; Marcel, S. ; Fierrez, J. 出处:Image Processing, IEEE Transactions on Volume: 23 Issue: 2 Date : Feb. 2014 Page(s): 710 - 724 DOI: 10.1109/TIP.2013.2292332 Referenced in: Biometrics Compendium, IEEE 摘 要 : To ensure the actual presence of a real legitimate trait in contrast to a fake self-manufactured synthetic or reconstructed sample is a significant problem in biometric authentication, which requires the development of new and efficient protection measures. In this paper, we present a novel software-based fake detection method that can be used in multiple 24 biometric systems to detect different types of fraudulent access attempts. The objective of the proposed system is to enhance the security of biometric recognition frameworks, by adding liveness assessment in a fast, user-friendly, and non-intrusive manner, through the use of image quality assessment. The proposed approach presents a very low degree of complexity, which makes it suitable for real-time applications, using 25 general image quality features extracted from one image (i.e., the same acquired for authentication purposes) to distinguish between legitimate and impostor samples. The experimental results, obtained on publicly available data sets of fingerprint, iris, and 2D face, show that the proposed method is highly competitive compared with other state-of-the-art approaches and that the analysis of the general image quality of real biometric samples reveals highly valuable information that may be very efficiently used to discriminate them from fake traits. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6671991 8.标题:Agent-Based Cloud Computing 作者:Kwang Mong Sim 出处:Services Computing, IEEE Transactions on Volume: 5 Issue: 4 Date : Fourth Quarter 2012 Page(s): 564 - 577 DOI: 10.1109/TSC.2011.52 摘要:Agent-based cloud computing is concerned with the design and development of software agents for bolstering cloud service discovery, service negotiation, and service composition. The significance of this work is introducing an agent-based paradigm for constructing software tools and testbeds for cloud resource management. The novel contributions of this work include: 1) developing Cloudle: an agent-based search engine for cloud service discovery, 2) showing that agent-based negotiation mechanisms can be effectively adopted for bolstering cloud service negotiation and cloud commerce, and 3) showing that agent-based cooperative problem-solving techniques can be effectively adopted for automating cloud service composition. Cloudle consists of 1) a service discovery agent that consults a cloud ontology for determining the similarities between providers' service specifications and consumers' service requirements, and 2) multiple cloud crawlers for building its database of services. Cloudle supports three types of reasoning: similarity reasoning, compatibility reasoning, and numerical reasoning. To support cloud commerce, this work devised a complex cloud negotiation mechanism that supports parallel negotiation activities in interrelated markets: a cloud service market between consumer agents and broker agents, and multiple cloud resource markets between broker agents and provider agents. Empirical results show that using the complex cloud negotiation mechanism, agents achieved high utilities and high success rates in negotiating for cloud resources. To automate cloud service composition, agents in this work adopt a focused selection contract net protocol (FSCNP) for dynamically selecting cloud services and use service capability tables (SCTs) to record the list of cloud agents and their services. Empirical results show that using FSCNP and SCTs, agents can successfully compose cloud services by autonomously selecting services. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6042853 9.标题:Cloud computing-based forensic analysis for collaborative network security management system 25 作者:Chen, Zhen ; Han, Fuye ; Cao, Junwei ; Jiang, Xin ; Chen, Shuo 出处:Tsinghua Science and Technology Volume: 18 Issue: 1 Date : Feb. 2013 Page(s): 40 - 50 DOI: 10.1109/TST.2013.6449406 摘要:Internet security problems remain a major challenge with many security concerns such as Internet worms, spam, and phishing attacks. Botnets, well-organized distributed network attacks, consist of a large number of bots that generate huge volumes of spam or launch Distributed Denial of Service (DDoS) attacks on victim hosts. New emerging botnet attacks degrade the status of Internet security further. To address these problems, a practical collaborative network security management system is proposed with an effective collaborative Unified Threat Management (UTM) and traffic probers. A distributed security overlay network with a centralized security center leverages a peer-to-peer communication protocol used in the UTMs collaborative module and connects them virtually to exchange network events and security rules. Security functions for the UTM are retrofitted to share security rules. In this paper, we propose a design and implementation of a cloud-based security center for network security forensic analysis. We propose using cloud storage to keep collected traffic data and then processing it with cloud computing platforms to find the malicious attacks. As a practical example, phishing attack forensic analysis is presented and the required computing and storage resources are evaluated based on real trace data. The cloud-based security center can instruct each collaborative UTM and prober to collect events and raw traffic, send them back for deep analysis, and generate new security rules. These new security rules are enforced by collaborative UTM and the feedback events of such rules are returned to the security center. By this type of close-loop control, the collaborative network security management system can identify and address new distributed attacks more quickly and effectively. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6449406 10.标题:Security threats in cloud computing 作者:Shaikh, F.B. ; Haider, S. 出处:Internet Technology and Secured Transactions (ICITST), 2011 International Conference for Date : 11-14 Dec. 2011 Page(s): 214 - 219 摘要:Cloud computing is set of resources and services offered through the Internet. Cloud services are delivered from data centers located throughout the world. Cloud computing facilitates its consumers by providing virtual resources via internet. General example of cloud services is Google apps, provided by Google and Microsoft SharePoint. The rapid growth in field of “cloud computing” also increases severe security concerns. Security has remained a constant issue for Open Systems and internet, when we are talking about security cloud really suffers. Lack of security is the only hurdle in wide adoption of cloud computing. Cloud computing is surrounded by many security issues like securing data, and examining the utilization of cloud by the cloud computing vendors. The wide acceptance www has raised security risks along with the uncountable benefits, so is the case with cloud computing. The boom in cloud computing has brought lots of security challenges for the consumers and service providers. How the end users of cloud computing know that their information is not having any availability and security issues? 26 Every one poses, Is their information secure? This study aims to identify the most vulnerable security threats in cloud computing, which will enable both end users and vendors to know about the key security threats associated with cloud computing. Our work will enable researchers and security professionals to know about users and vendors concerns and critical analysis about the different security models and tools proposed. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6148380 11.标题:Sampling Circuits That Break the kT/C Thermal Noise Limit 作者:Kapusta, R. ; Haiyang Zhu ; Lyden, C. 出处:Solid-State Circuits, IEEE Journal of Volume: 49 Issue: 8 Date : Aug. 2014 Page(s): 1694 - 1701 DOI: 10.1109/JSSC.2014.2320465 摘要:Several circuit-level techniques are described which are used to reduce or cancel thermal noise and break the so-called kT/C limit. kT/C noise describes the total thermal noise power added to a signal when a sample is taken on a capacitor. In the first proposed technique, the sampled thermal noise is reduced by altering the relationship between the sampling bandwidth and the dominant noise source, providing a powerful, new degree of freedom in circuit design. In the second proposed technique, thermal noise sampled on an input capacitor is actively canceled using an amplifier, so that the noise at the amplifier output can be controlled independently of input capacitor size. Measurements from two test chips are presented which demonstrate sampled thermal noise power reduction of 48% and 67%, respectively, when compared with conventional kT/C-limited sampling. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6814935 12.标题:Image quality assessment: from error visibility to structural similarity 作者:Zhou Wang ; Bovik, A.C. ; Sheikh, H.R. ; Simoncelli, E.P. 出处:Image Processing, IEEE Transactions on Volume: 13 Issue: 4 Date : April 2004 Page(s): 600 - 612 DOI: 10.1109/TIP.2003.819861 摘要:Objective methods for assessing perceptual image quality traditionally attempted to quantify the visibility of errors (differences) between a distorted image and a reference image using a variety of known properties of the human visual system.

As a specific example of this concept, we develop a structural similarity index and demonstrate its promise through a set of intuitive examples, as well as comparison to both subjective ratings and state-of-the-art objective methods on a database of images compressed with JPEG and JPEG2000.

The integration of these new radio concepts, such as massive MIMO, ultra dense networks, moving networks, and device-to-device, ultra reliable, and massive machine communications, will allow 5G to support the expected increase in mobile data volume while broadening the range of application domains that mobile communications can support beyond 2020.

If x is known to be compressible by transform coding with a known transform, and we reconstruct via the nonlinear procedure defined here, the 29 number of measurements n can be dramatically smaller than the size m. Thus, certain natural classes of images with m pixels need only n=O(m1/4log5/2(m)) nonadaptive nonpixel samples for faithful recovery, as opposed to the usual m pixel samples. More specifically, suppose x has a sparse representation in some orthonormal basis (e.g., wavelet, Fourier) or tight frame (e.g., curvelet, Gabor)-so the coefficients belong to an lscrp ball for 0<ples1. The N most important coefficients in that expansion allow reconstruction with lscr2 error O(N1/2-1p/). It is possible to design n=O(Nlog(m)) nonadaptive measurements allowing reconstruction with accuracy comparable to that attainable with direct knowledge of the N most important coefficients. Moreover, a good approximation to those N important coefficients is extracted from the n measurements by solving a linear program-Basis Pursuit in signal processing. The nonadaptive measurements have the character of "random" linear combinations of basis/frame elements. Our results use the notions of optimal recovery, of n-widths, and information-based complexity. We estimate the Gel'fand n-widths of lscrp balls in high-dimensional Euclidean space in the case 0<ples1, and give a criterion identifying near- optimal subspaces for Gel'fand n-widths. We show that "most" subspaces are near-optimal, and show that convex optimization (Basis Pursuit) is a near-optimal way to extract information derived from these near-optimal subspaces 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=1614066 18.标题:Power-Electronic Systems for the Grid Integration of Renewable Energy Sources: A Survey 作者:Carrasco, J.M. ; Franquelo, L.G. ; Bialasiewicz, J.T. ; Galvan, E. ; Guisado, R.C.P. ; Prats, Ma.A.M. ; Leon, J.I. ; Moreno-Alfonso, N. 出处:Industrial Electronics, IEEE Transactions on Volume: 53 Issue: 4 Date : June 2006 Page(s): 1002 - 1016 DOI: 10.1109/TIE.2006.878356 摘要:The use of distributed energy resources is increasingly being pursued as a supplement and an alternative to large conventional central power stations.

This is achieved by separately considering the on-time and the off-time of the switching period. The derivation is shown in detail for a synchronous buck converter and the model for a boost converter is also presented. The model for the buck converter is then used for the design of two digital feedback controllers, which exploit the additional insight in the converter dynamics. First, a digital multiloop PID controller is implemented, where the design is based on loop-shaping of the proposed frequency-domain transfer functions. And second, the design and the implementation of a digital LQG state-feedback controller, based on the proposed time-domain state-space model, is presented for the same converter topology. Experimental results are given for the digital multiloop PID controller integrated on an application-specified integrated circuit in a 0.13 μm CMOS technology, as well as for the state-feedback controller implemented on an FPGA. Tight output voltage regulation and an excellent dynamic performance is achieved, as the dynamics of the converter under variable frequency operation are considered during the design of both implementations. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6472322 21.标题:A Computational Approach to Edge Detection 作者:Canny, John 出处:Pattern Analysis and Machine Intelligence, IEEE Transactions on Volume: PAMI-8 Issue: 6 Date : Nov. 1986 Page(s): 679 - 698 DOI: 10.1109/TPAMI.1986.4767851 摘要:This paper describes a computational approach to edge detection. The success of the approach depends on the definition of a comprehensive set of goals for the computation of edge points. These goals must be precise enough to delimit the desired behavior of the detector while making minimal assumptions about the form of the solution. We define detection and localization criteria for a class of edges, and present mathematical forms for these criteria as functionals on the operator impulse response. A third criterion is then added to ensure that the detector has only one response to a single edge. We use the criteria in numerical optimization to derive detectors for 31 several common image features, including step edges. On specializing the analysis to step edges, we find that there is a natural uncertainty principle between detection and localization performance, which are the two main goals. With this principle we derive a single operator shape which is optimal at any scale. The optimal detector has a simple approximate implementation in which edges are marked at maxima in gradient magnitude of a Gaussian-smoothed image. We extend this simple detector using operators of several widths to cope with different signal-to-noise ratios in the image. We present a general method, called feature synthesis, for the fine-to-coarse integration of information from operators at different scales. Finally we show that step edge detector performance improves considerably as the operator point spread function is extended along the edge. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=4767851 22.标题:Geometric Algebra for Electrical and Electronic Engineers 作者:Chappell, J.M. ; Drake, S.P. ; Seidel, C.L. ; Gunn, L.J. ; Iqbal, A. ; Allison, A. ; Abbott, D. 出处:Proceedings of the IEEE Volume: 102 Issue: 9 Date : Sept. 2014 Page(s): 1340 - 1363 DOI: 10.1109/JPROC.2014.2339299 摘要:In this paper, we explicate the suggested benefits of Clifford's geometric algebra (GA) when applied to the field of electrical engineering. Engineers are always interested in keeping formulas as simple or compact as possible, and we illustrate that geometric algebra does provide such a simplified representation in many cases. We also demonstrate an additional structural check provided by GA for formulas in addition to the usual checking of physical dimensions. Naturally, there is an initial learning curve when applying a new method, but it appears to be worth the effort, as we show significantly simplified formulas, greater intuition, and improved problem solving in many cases. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6876131 23.标题:An Introduction To Compressive Sampling 作者:Candes, E.J. ; Wakin, M.B. 出处:Signal Processing Magazine, IEEE Volume: 25 Issue: 2 Date : March 2008 Page(s): 21 - 30 DOI: 10.1109/MSP.2007.914731 摘要:Conventional approaches to sampling signals or images follow Shannon's theorem: the sampling rate must be at least twice the maximum frequency present in the signal (Nyquist rate). In the field of data conversion, standard analog-to-digital converter (ADC) technology implements the usual quantized Shannon representation - the signal is uniformly sampled at or above the Nyquist rate. This article surveys the theory of compressive sampling, also known as compressed sensing or CS, a novel sensing/sampling paradigm that goes against the common wisdom in data acquisition. CS theory asserts that one can recover certain signals and images from far fewer samples or measurements than traditional methods use. 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=4472240 32 24.标题:A tutorial on hidden Markov models and selected applications in speech recognition 作者:Rabiner, L. 出处:Proceedings of the IEEE Volume: 77 Issue: 2 Date : Feb 1989 Page(s): 257 - 286 DOI: 10.1109/5.18626 摘要:This tutorial provides an overview of the basic theory of hidden Markov models (HMMs) as originated by L.E. Baum and T. Petrie (1966) and gives practical details on methods of implementation of the theory along with a description of selected applications of the theory to distinct problems in speech recognition. Results from a number of original sources are combined to provide a single source of acquiring the background required to pursue further this area of research. The author first reviews the theory of discrete Markov chains and shows how the concept of hidden states, where the observation is a probabilistic function of the state, can be used effectively. The theory is illustrated with two simple examples, namely coin-tossing, and the classic balls-in-urns system. Three fundamental problems of HMMs are noted and several practical techniques for solving these problems are given. The various types of HMMs that have been studied, including ergodic as well as left-right models, are described 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=18626 25.标题:Overview of Control and Grid Synchronization for Distributed Power Generation Systems 作者:Blaabjerg, F. ; Teodorescu, R. ; Liserre, M. ; Timbus, A.V. 出处:Industrial Electronics, IEEE Transactions on Volume: 53 Issue: 5 Date : Oct. 2006 Page(s): 1398 - 1409 DOI: 10.1109/TIE.2006.881997 摘要:Renewable energy sources like wind, sun, and hydro are seen as a reliable alternative to the traditional energy sources such as oil, natural gas, or coal. Distributed power generation systems (DPGSs) based on renewable energy sources experience a large development worldwide, with Germany, Denmark, Japan, and USA as leaders in the development in this field. Due to the increasing number of DPGSs connected to the utility network, new and stricter standards in respect to power quality, safe running, and islanding protection are issued. As a consequence, the control of distributed generation systems should be improved to meet the requirements for grid interconnection. This paper gives an overview of the structures for the DPGS based on fuel cell, photovoltaic, and wind turbines. In addition, control structures of the grid-side converter are presented, and the possibility of compensation for low-order harmonics is also discussed. Moreover, control strategies when running on grid faults are treated. This paper ends up with an overview of synchronization methods and a discussion about their importance in the control 链接:http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=1705631 33 四、ACM 最新会议 (来源:http://www.acm.org/) 1. 会 议 名 称 : BICT '14: 8th International Conference on Bio-inspired Information and Communications Technologies (formerly BIONETICS) 会议时间: December 1st-3rd,2014 会议地点:Boston , MA USA 会议简介:8th International Conference on Bio-inspired Information and Communications Technologies (formerly BIONETICS) - BICT 2014 You are cordially invited to participate in BICT 2014 to be held at UMass Club, MA, USA, in December 2014.

Adversaries have an asymmetric advantage in that they have the time to study a system, identify its vulnerabilities, and choose the time and place of attack to gain the maximum benefit. The idea of moving-target defense (MTD) is to impose the same asymmetric disadvantage on the attacker by making systems dynamic and harder to predict. With a constantly changing system and its ever adapting attack surface, the attacker will have to deal with a great deal of uncertainty just like defenders do today. The ultimate goal is to level the cybersecurity playing field for defenders versus attackers. This workshop seeks to bring together researchers from academia, government, and industry to report on the latest research efforts on moving-target defense, and to have productive discussion and constructive debate on this topic. We solicit submissions on original research in the broad area of MTD, with possible topics such as those listed below. Since this is still a research area in a nascent stage, the list should only be used as a reference. We welcome all works that fall under the 37 broad scope of moving target defense, including research that shows negative results. System randomization Artificial diversity Cyber maneuver Bio-inspired defenses Dynamic network configuration Moving target in the cloud System diversification techniquesk Dynamic compilation techniques Adaptive defenses Analytical models for MTD Large-scale MTD (using multiple techniques) Paper Submissions Submitted papers must not substantially overlap papers that have been published or that are simultaneously submitted to a journal or a conference with proceedings.

With the aim to ensure its environmental sustainability for the future, the aviation industry has set stringent and ambitious future environmental goals. In order to achieve these goals it is now in pursuit of revolutionary greener alternatives to the conventional aircraft and propulsion systems– it has set out to discover disruptive technologies. The search for future disruptive technologies in aviation requires cross-disciplinary effort. This effort will be focused on feasible airframes and propulsion systems, their optimal integration, application of alternative fuels, aviation safety and reliability, noise reduction and operating cost amongst the key factors. Multi-objective assessments have indicated that significant changes in vehicle and propulsion system designs are required to meet the stringent environmental (ICAO, NASA’s N+3 and Flight path 2050) targets of the future. The assessments further indicate that, amongst many evaluated options and despite a significant number of technological challenges, Turbo-electric Distributed Propulsion (TeDP) on a Blended Wing Body (BWB) airframe has the required potential to eventually achieve these targets as this concept will change the nature of the way the aircraft will interact with and affect the environment. Conferences on propulsion have primarily focused on evolutionary improvements to conventional gas turbine technologies based on the Brayton Cycle. This special 2 day conference is aimed specifically at Distributed Propulsion and Turbo-electric systems, and presenting it as the next disruptive technology. The focus of the conference will be to: Discuss latest research and to share ideas on the subject, whilst engaging the younger generation of engineers to start thinking of the future of propulsion. Provide the airframe and propulsion industries with an insight into the state-of-the-art research. 40 conducted on Distributed Propulsion in the recent years and the benefits this technology may offer in terms of reduced environmental footprint of civil aviation.

This is the highest efficiency reported for pure sulfide Cu2ZnSnS4 prepared by any method. Consistent with literature, the optimal composition is Cu-poor and Zn-rich despite the precipitation of secondary phases (e.g., ZnS). Despite a very thin absorber thickness (similar to 600 nm), a reasonably good short-circuit 49 current was obtained. Time-resolved photoluminescence measurements suggest a minority carrier-diffusion length on the order of several hundreds of nanometers and relatively good collection of photo-carriers across the entire absorber thickness.

Our attention is focused on the design of full-and reduced-order filters that guarantee the filtering error system to be asymptotically stable with a prescribed H-infinity performance. Sufficient conditions for the obtained filtering error system are proposed by applying an input-output approach and a two-term approximation method, which is employed to approximate the time-varying delay. The corresponding full-and reduced-order filter design is cast into a convex optimization problem, which can be efficiently solved by standard numerical algorithms. Finally, simulation examples are provided to illustrate the effectiveness of the proposed approaches. 地址:Harbin Inst Technol, Harbin 150001, Peoples R China.

Both the sectorlike nonlinearities and the norm-bounded uncertainties enter into the system in random ways, and such randomly occurring uncertainties and randomly occurring nonlinearities obey certain mutually uncorrelated Bernoulli distributed white noise sequences. The mixed time delays consist of both the discrete and the distributed delays. The time-varying delays are allowed in state. By employing the idea of delay fractioning and constructing a new Lyapunov-Krasovskii functional, sufficient conditions are established to ensure the stability of the system dynamics in the specified sliding surface by solving a certain semidefinite programming problem. A full-state feedback SMC law is designed to guarantee the reaching condition. A simulation example is given to demonstrate the effectiveness of the proposed SMC scheme. 52 地址:Harbin Inst Technol, Res Inst Intelligent Control & Syst, Harbin 150001, Peoples R China.

Market forces demonstrate a drive towards products benign to natural environment increasing the importance of renewable materials. The development of second generation bioethanol from lignocellulosic biomass serves many advantages from both energy and environmental point of views. Biomass an inexpensive feedstock considered sustainable and renewable, is an option with the potential to replace a wide diversity of fossil based products within the energy sector; heat, power, fuels, materials and chemicals. Lignocellulose is a major structural component of woody and non-woody plants and consists of cellulose, hemicellulose and lignin. The effective utilization of all the three components would play a significant role in the economic viability of cellulosic ethanol. Biomass conversion process involves five major steps, choice of suitable biomass, effective pretreatment, production of saccharolytic enzymes-cellulases and hemicellulases, fermentation of hexoses and pentoses and downstream processing. Within the context of production of fuels from biomass, pretreatment has come to denote processes by which cellulosic biomass is made amenable to the action of hydrolytic enzymes. The limited effectiveness of current enzymatic process on lignocellulose is thought to be due to the relative difficulties in pretreating the feedstocks. The present review is a comprehensive state of the art describing the advancement in recent pretreaments, metabolic engineering approaches with special emphasis on the latest developments in consolidated biomass 53 processing, current global scenario of bioethanol pilot plants and biorefinery concept for the production of biofuels and bioproducts.

However, great challenges are also met due to the network-induced imperfections. Such network-induced imperfections are handled as various constraints, which should appropriately be considered in the analysis and design of NCSs. In this paper, the main methodologies suggested in the literature to cope with typical network-induced constraints, namely time delays, packet losses and disorder, time-varying transmission intervals, competition of multiple nodes accessing networks, and data quantization are surveyed; the constraints suggested in the literature on the first two types of constraints are updated in different categorizing ways; and those on the latter three types of constraints are extended. 地址:Harbin Inst Technol, Space Control & Inertial Technol Res Ctr, Harbin 150080, Peoples R China.

However, at the open-circuit condition, the carriers have no place to go. They build up in density, and ideally, they emit external luminescence that exactly balances the incoming sunlight. Any additional nonradiative recombination impairs the carrier density buildup, limiting the open-circuit voltage. At open circuit, efficient external luminescence is an indicator of low internal optical losses. Thus, efficient external luminescence is, counterintuitively, a necessity for approaching the Shockley-Queisser (SQ) efficiency limit. A great solar cell also needs to be a great light-emitting diode. Owing to the narrow escape cone for light, efficient external emission requires repeated attempts and demands an internal luminescence efficiency >> 90%. 地址:Univ Calif Berkeley, Lawrence Berkeley Natl Lab, Div Mat Sci, Berkeley, CA 94720 USA.

However, the commercialization of Li/S battery still cannot be realized due to many problematic issues, including short cycle life, low cycling efficiency, poor safety and a high self-discharge rate. All these issues are related to the dissolution of lithium polysulfide (PS), the series of sulfur reduction intermediates, in liquid electrolyte and to resulting parasitic reactions with the lithium anode and electrolyte components. On the other hand, the dissolution of PS is essential for the performance of a Li/S cell. Without dissolution of PS, the Li/S cell cannot operate progressively due to the non-conductive nature of elemental sulfur and its reduction products. In this review article, we start with the fundamental chemistry of elemental sulfur in order to discuss the problems and solutions of liquid electrolyte Li/S battery.

Here, we report a thin-film solar cell with solution-processed Cu(In,Ga)(S,Se)(2) (CIGS) absorber. The power conversion efficiency of 15.2% is the highest published value for a pure solution deposition technique for any photovoltaic absorber material and is on par with the best nonvacuum-processed CIGS devices. We compare the performance of our cell with a world champion vacuum-deposited CIGS cell and perform detailed characterization, such as biased quantum efficiency, temperature-dependent electrical measurement, time-resolved photoluminescence, and capacitance spectroscopy.

A new comparison model is proposed by employing a new approximation for time-varying delay state, and then, a delay partitioning method is used to analyze the scaled small gain of this comparison model. A sufficient condition on discrete-time T-S fuzzy systems with time-varying delays, which guarantees the corresponding closed-loop system to be asymptotically stable and has an induced l(2) disturbance attenuation performance, is derived by employing the scaled small-gain theorem. Then, the solvability condition for the induced l(2) DOF control is also established, by which the DOF controller can be solved as linear matrix inequality optimization problems. Finally, examples are provided to illustrate the effectiveness of the proposed approaches. 地址:Harbin Inst Technol, Space Control & Inertial Technol Res Ctr, Harbin 150001, Peoples R China.

In an effort to understand the benefits and drawbacks of existing methods, we empirically compare five state-of-the-art superpixel algorithms for their ability to adhere to image boundaries, speed, memory efficiency, and their impact on segmentation performance. We then introduce a new superpixel algorithm, simple linear iterative clustering (SLIC), which adapts a k-means clustering approach to efficiently generate superpixels. Despite its simplicity, SLIC adheres to boundaries as well as or better than previous methods. At the same time, it is faster and more memory efficient, improves segmentation performance, and is straightforward to extend to supervoxel generation. 地址:Ecole Polytech Fed Lausanne, Sch Comp & Commun Sci, Images & Visual Representat Grp, CH-1015 Lausanne, Switzerland.

The varying sprung and unsprung masses, the unknown actuator nonlinearity, and the suspension performances are taken into account simultaneously, and the corresponding mathematical model is established. The T-S fuzzy system is used to describe the original nonlinear system for the control-design aim via the sector nonlinearity approach. A sufficient condition is proposed for the asymptotical stability of the designing sliding motion. An adaptive sliding-mode controller is designed to guarantee the reachability of the specified switching surface. The condition can be converted to the convex optimization problems. Simulation results for a half-vehicle active suspension model are provided to demonstrate the effectiveness of the proposed control schemes. 地址:Univ Portsmouth, Sch Creat Technol, Intelligent Syst & Biomed Robot Grp, Portsmouth PO1 2DJ, Hants, England.

Based on the coupling identification concept, a novel coupled-least-squares (C-LS) parameter identification algorithm is introduced for the purpose of avoiding the matrix inversion in the multivariable recursive least-squares (RLS) algorithm for estimating the parameters of the multiple linear regression models. The analysis indicates that the C-LS algorithm does not involve the matrix inversion and requires less computationally efforts than the multivariable RLS algorithm, and that the parameter estimates given by the C-LS algorithm converge to their true values. Simulation results confirm the presented convergence theorems. 地址:Jiangnan Univ, Minist Educ, Key Lab Adv Proc Control Light Ind, Wuxi 214122, Peoples R China.

The mesostructure of biological materials, such as the outer calcitic shell of molluscs, is characterized by many parameters and the question arises as to what extent they all are, or need to be, controlled biologically. Here, we analyse the three-dimensional structure of the calcite-based prismatic layer of Pinna nobilis6, 7, 8, the giant Mediterranean fan mussel, using high-resolution synchrotron-based microtomography. We show that the evolution of the layer is statistically self-similar and, remarkably, its morphology and mesostructure can be fully predicted using classical materials science theories for normal grain growth9, 10, 11, 12, 13, 14, 15, 16. These findings are a fundamental step in understanding the constraints that dictate the shape of these biogenic minerals and shed light on how biological organisms make use of thermodynamics to generate complex morphologies. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4110.html 2.标题: Re-entrant solidification in polymer–colloid mixtures as a consequence of competing entropic and enthalpic attractions AOP 作者:Lang Feng, Bezia Laderman, Stefano Sacanna & Paul Chaikin 摘要:In polymer–colloid mixtures1, 2, non-adsorbing polymers dispersed with much larger colloids provide a universal yet specific entropic attraction between the colloids3, 4, 5, 6, 7, 8. Such so-called depletion interaction2, 3 arises from an osmotic-pressure imbalance caused by the polymers and is considered to be independent of temperature. Here we show that, for the most commonly used polymer–colloid depletion systems5, 6, the polymer undergoes a crossover from non-adsorbing to adsorbing9 and that, consequently, the effective colloidal interactions depend on temperature. We also find that a combination of the enthalpic (polymer bridging10, 11, 12) and entropic (polymer exclusion2, 3, 4) interactions, both attractive, leads to a re-entrant regime where the colloids are dispersed and form solids both on heating and on cooling. We provide a simple model to explain the observed transitions and to fill the theoretical gap at the polymer-adsorption crossover2, 9. Our findings open possibilities for colloidal self-assembly5, 13, the formation of colloidal crystals14, 15 and glasses16, and the behaviour of temperature-controlled viscoelastic materials. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4109.html 3.标题: Giant spin splitting of the two-dimensional electron gas at the surface of SrTiO3 AOP 作者:A. F. Santander-Syro, F. Fortuna, C. Bareille, T. C. Rödel, G. Landolt, N. C. Plumb, J. H. Dil & M. Radović 摘要:Two-dimensional electron gases (2DEGs) forming at the interfaces of transition metal oxides1, 2, 3 exhibit a range of properties, including tunable insulator–superconductor–metal transitions4, 5, 6, large magnetoresistance7, coexisting ferromagnetism and superconductivity8, 9, and a spin splitting of a few meV (refs 10, 11). Strontium titanate (SrTiO3), the cornerstone of such oxide-based electronics, is a transparent, non-magnetic, wide-bandgap insulator in the bulk, and has recently been found to host a surface 2DEG (refs 12, 13, 14, 15). The most strongly confined carriers within this 2DEG comprise two subbands, separated by an energy gap of 90 58 meV and forming concentric circular Fermi surfaces12, 13, 15. Using spin- and angle-resolved photoemission spectroscopy (SARPES), we show that the electron spins in these subbands have opposite chiralities. Although the Rashba effect might be expected to give rise to such spin textures, the giant splitting of almost 100 meV at the Fermi level is far larger than anticipated16, 17. Moreover, in contrast to a simple Rashba system, the spin-polarized subbands are non-degenerate at the Brillouin zone centre. This degeneracy can be lifted by time-reversal symmetry breaking, implying the possible existence of magnetic order. These results show that confined electronic states at oxide surfaces can be endowed with novel, non-trivial properties that are both theoretically challenging to anticipate and promising for technological applications. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4107.html 4.标题: Liquid-like pseudoelasticity of sub-10-nm crystalline silver p 标题:s AOP 作者:Jun Sun, Longbing He, Yu-Chieh Lo, Tao Xu, Hengchang Bi, Litao Sun, Ze Zhang, Scott X. Mao & Ju Li 摘要:In nanotechnology, small-volume metals with large surface area are used as electrodes, catalysts, interconnects and antennae1, 2, 3, 4. Their shape stability at room temperature has, however, been questioned. Using in situ high-resolution transmission electron microscopy, we find that Ag nanoparticles can be deformed like a liquid droplet but remain highly crystalline in the interior, with no sign of dislocation activity during deformation5, 6. Surface-diffusion-mediated pseudoelastic deformation is evident at room temperature, which can be driven by either an external force or capillary-energy minimization. Atomistic simulations confirm that such highly unusual Coble pseudoelasticity can indeed happen for sub-10-nm Ag particles at room temperature and at timescales from seconds to months. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4105.html 5.Resonant energy transfer of triplet excitons from pentacene to PbSe nanocrystals AOP 作者:Maxim Tabachnyk, Bruno Ehrler, Simon Gélinas, Marcus L. Böhm, Brian J. Walker, Kevin P. Musselman, Neil C. Greenham, Richard H. Friend & Akshay Rao 摘要: The efficient transfer of energy between organic and inorganic semiconductors is a widely sought after property, but has so far been limited to the transfer of spin-singlet excitons. Here we report efficient resonant-energy transfer of molecular spin-triplet excitons from organic semiconductors to inorganic semiconductors. We use ultrafast optical absorption spectroscopy to track the dynamics of triplets, generated in pentacene through singlet exciton fission, at the interface with lead selenide (PbSe) nanocrystals. We show that triplets transfer to PbSe rapidly (<1 ps) and efficiently, with 1.9 triplets transferred for every photon absorbed in pentacene, but only when the bandgap of the nanocrystals is close to resonance (±0.2 eV) with the triplet energy. Following triplet transfer, the excitation can undergo either charge separation, allowing photovoltaic operation, or radiative recombination in the nanocrystal, enabling luminescent harvesting of triplet exciton energy in light-emitting structures. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4093.html 6.标 题 :Energy harvesting of non-emissive triplet excitons in tetracene by emissive PbS nanocrystals AOP 作者:Nicholas J. Thompson, Mark W. B. Wilson, Daniel N. Congreve, Patrick R. Brown, Jennifer 59 M. Scherer, Thomas S. Bischof, Mengfei Wu, Nadav Geva, Matthew Welborn, Troy Van Voorhis, Vladimir Bulović, Moungi G. Bawendi & Marc A. Baldo 摘要:Triplet excitons are ubiquitous in organic optoelectronics, but they are often an undesirable energy sink because they are spin-forbidden from emitting light and their high binding energy hinders the generation of free electron–hole pairs. Harvesting their energy is consequently an important technological challenge. Here, we demonstrate direct excitonic energy transfer from ‘dark’ triplets in the organic semiconductor tetracene to colloidal PbS nanocrystals, thereby successfully harnessing molecular triplet excitons in the near infrared. Steady-state excitation spectra, supported by transient photoluminescence studies, demonstrate that the transfer efficiency is at least (90 ± 13)%. The mechanism is a Dexter hopping process consisting of the simultaneous exchange of two electrons. Triplet exciton transfer to nanocrystals is expected to be broadly applicable in solar and near-infrared light-emitting applications, where effective molecular phosphors are lacking at present. In particular, this route to ‘brighten’ low-energy molecular triplet excitons may permit singlet exciton fission sensitization of conventional silicon solar cells. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4097.html 7.标题:Oligopeptide complex for targeted non-viral gene delivery to adipocytes AOP 作者:Young-Wook Won, Partho Protim Adhikary, Kwang Suk Lim, Hyung Jin Kim, Jang Kyoung Kim & Yong-Hee Kim 摘要: Commercial anti-obesity drugs acting in the gastrointestinal tract or the central nervous system have been shown to have limited efficacy and severe side effects. Anti-obesity drug development is thus focusing on targeting adipocytes that store excess fat. Here, we show that an adipocyte-targeting fusion-oligopeptide gene carrier consisting of an adipocyte-targeting sequence and 9-arginine (ATS–9R) selectively transfects mature adipocytes by binding to prohibitin. Injection of ATS–9R into obese mice confirmed specific binding of ATS–9R to fat vasculature, internalization and gene expression in adipocytes. We also constructed a short-hairpin RNA (shRNA) for silencing fatty-acid-binding protein 4 (shFABP4), a key lipid chaperone in fatty-acid uptake and lipid storage in adipocytes. Treatment of obese mice with ATS–9R/shFABP4 led to metabolic recovery and body-weight reduction (>20%). The ATS–9R/shFABP4 oligopeptide complex could prove to be a safe therapeutic approach to regress and treat obesity as well as obesity-induced metabolic syndromes. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4092.html 8.标题:Extreme electronic bandgap modification in laser-crystallized silicon optical fibres AOP 作者:Noel Healy, Sakellaris Mailis, Nadezhda M. Bulgakova, Pier J. A. Sazio, Todd D. Day, Justin R. Sparks, Hiu Y. Cheng, John V. Badding & Anna C. Peacock 摘要:For decades now, silicon has been the workhorse of the microelectronics revolution and a key enabler of the information age. Owing to its excellent optical properties in the near- and mid-infrared, silicon is now promising to have a similar impact on photonics. The ability to incorporate both optical and electronic functionality in a single material offers the tantalizing prospect of amplifying, modulating and detecting light within a monolithic platform. However, a direct consequence of silicon’s transparency is that it cannot be used to detect light at telecommunications wavelengths. Here, we report on a laser processing technique developed for our silicon fibre technology through which we can modify the electronic band structure of the 60 semiconductor material as it is crystallized. The unique fibre geometry in which the silicon core is confined within a silica cladding allows large anisotropic stresses to be set into the crystalline material so that the size of the bandgap can be engineered. We demonstrate extreme bandgap reductions from 1.11 eV down to 0.59 eV, enabling optical detection out to 2,100 nm. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4098.html 9.标题: Vertical and in-plane heterostructures from WS2/MoS2 monolayers AOP 作者:Yongji Gong, Junhao Lin, Xingli Wang, Gang Shi, Sidong Lei, Zhong Lin, Xiaolong Zou, Gonglan Ye, Robert Vajtai, Boris I. Yakobson, Humberto Terrones, Mauricio Terrones, Beng Kang Tay, Jun Lou, Sokrates T. Pantelides, Zheng Liu, Wu Zhou & Pulickel M. Ajayan 摘要:Layer-by-layer stacking or lateral interfacing of atomic monolayers has opened up unprecedented opportunities to engineer two-dimensional heteromaterials. Fabrication of such artificial heterostructures with atomically clean and sharp interfaces, however, is challenging. Here, we report a one-step growth strategy for the creation of high-quality vertically stacked as well as in-plane interconnected heterostructures of WS2/MoS2 via control of the growth temperature. Vertically stacked bilayers with WS2 epitaxially grown on top of the MoS2 monolayer are formed with preferred stacking order at high temperature. A strong interlayer excitonic transition is observed due to the type II band alignment and to the clean interface of these bilayers. Vapour growth at low temperature, on the other hand, leads to lateral epitaxy of WS2 on MoS2 edges, creating seamless and atomically sharp in-plane heterostructures that generate strong localized photoluminescence enhancement and intrinsic p–n junctions. The fabrication of heterostructures from monolayers, using simple and scalable growth, paves the way for the creation of unprecedented two-dimensional materials with exciting properties. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4091.html 10.标题:Direct correlation of single-molecule properties with bulk mechanical performance for the biomimetic design of polymers AOP 作者:Jaeyoon Chung, Aaron M. Kushner, Adam C. Weisman & Zhibin Guan 摘要:For rational design of advanced polymeric materials, it is critical to establish a clear mechanistic link between the molecular structure of a polymer and the emergent bulk mechanical properties. Despite progress towards this goal, it remains a major challenge to directly correlate the bulk mechanical performance to the nanomechanical properties of individual constituent macromolecules. Here, we show a direct correlation between the single-molecule nanomechanical properties of a biomimetic modular polymer and the mechanical characteristics of the resulting bulk material. The multi-cyclic single-molecule force spectroscopy (SMFS) data enabled quantitative derivation of the asymmetric potential energy profile of individual module rupture and re-folding, in which a steep dissociative pathway accounted for the high plateau modulus, while a shallow associative well explained the energy-dissipative hysteresis and dynamic, adaptive recovery. These results demonstrate the potential for SMFS to serve as a guide for future rational design of advanced multifunctional materials. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4090.html 11.标题: Topologically protected excitons in porphyrin thin films AOP 作者:Joel Yuen-Zhou, Semion K. Saikin, Norman Y. Yao & Alán Aspuru-Guzik 61 摘要:The control of exciton transport in organic materials is of fundamental importance for the development of efficient light-harvesting systems. This transport is easily deteriorated by traps in the disordered energy landscape. Here, we propose and analyse a system that supports topological Frenkel exciton edge states. Backscattering of these chiral Frenkel excitons is prohibited by symmetry, ensuring that the transport properties of such a system are robust against disorder. To implement our idea, we propose a two-dimensional periodic array of tilted porphyrins interacting with a homogeneous magnetic field. This field serves to break time-reversal symmetry and results in lattice fluxes that mimic the Aharonov–Bohm phase acquired by electrons. Our proposal is the first blueprint for realizing topological phases of matter in molecular aggregates and suggests a paradigm for engineering novel excitonic materials. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4073.html 12.标题:Benzene-derived carbon nanothreads AOP 作者:Thomas C. Fitzgibbons, Malcolm Guthrie, En-shi Xu, Vincent H. Crespi, Stephen K. Davidowski, George D. Cody, Nasim Alem & John V. Badding 摘要:Low-dimensional carbon nanomaterials such as fullerenes, nanotubes, graphene and diamondoids have extraordinary physical and chemical properties1, 2. Compression-induced polymerization of aromatic molecules could provide a viable synthetic route to ordered carbon nanomaterials3, 4, but despite almost a century of study5, 6, 7, 8, 9 this approach has produced only amorphous products10, 11, 12, 13, 14. Here we report recovery to ambient pressure of macroscopic quantities of a crystalline one- dimensional sp3 carbon nanomaterial formed by high-pressure solid-state reaction of benzene. X-ray and neutron diffraction, Raman spectroscopy, solid-state NMR, transmission electron microscopy and first-principles calculations reveal closepacked bundles of subnanometre-diameter sp3-bonded carbon threads capped with hydrogen, crystalline in two dimensions and short-range ordered in the third. These nanothreads promise extraordinary properties such as strength and stiffness higher than that of sp2 carbon nanotubes or conven tional high-strength polymers15. They may be the first member of a new class of ordered sp3 nanomaterials synthesized by kinetic control of high-pressure solid-state reactions. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4088.html 13.标题:Determination of the 3D shape of a nanoscale crystal with atomic resolution from a single image AOP 作者:C. L. Jia, S. B. Mi, J. Barthel, D. W. Wang, R. E. Dunin-Borkowski, K. W. Urban & A. Thust 摘要:Although the overall atomic structure of a nanoscale crystal is in principle accessible by modern transmission electron microscopy, the precise determination of its surface structure is an intricate problem. Here, we show that aberration-corrected transmission electron microscopy, combined with dedicated numerical evaluation procedures, allows the three-dimensional shape of a thin MgO crystal to be determined from only one single high-resolution image. The sensitivity of the reconstruction procedure is not only sufficient to reveal the surface morphology of the crystal with atomic resolution, but also to detect the presence of adsorbed impurity atoms. The single-image approach that we introduce offers important advantages for three-dimensional studies of radiation-sensitive crystals. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4087.html 62 14.标题:Two-step nucleation mechanism in solid–solid phase transitions AOP 作者:Yi Peng, Feng Wang, Ziren Wang, Ahmed M. Alsayed, Zexin Zhang, Arjun G. Yodh & Yilong Han 摘 要 :The microscopic kinetics of ubiquitous solid–solid phase transitions remain poorly understood. Here, by using single-particle-resolution video microscopy of colloidal films of diameter-tunable microspheres, we show that transitions between square and triangular lattices occur via a two-step diffusive nucleation pathway involving liquid nuclei. The nucleation pathway is favoured over the direct one-step nucleation because the energy of the solid/liquid interface is lower than that between solid phases. We also observed that nucleation precursors are particle-swapping loops rather than newly generated structural defects, and that coherent and incoherent facets of the evolving nuclei exhibit different energies and growth rates that can markedly alter the nucleation kinetics. Our findings suggest that an intermediate liquid should exist in the nucleation processes of solid–solid transitions of most metals and alloys, and provide guidance for better control of the kinetics of the transition and for future refinements of solid–solid transition theory. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4083.html 15.标题: Digital metamaterials AOP 作者:Cristian Della Giovampaola & Nader Engheta 摘要:Balancing complexity and simplicity has played an important role in the development of many fields in science and engineering. One of the well-known and powerful examples of such balance can be found in Boolean algebra and its impact on the birth of digital electronics and the digital information age. The simplicity of using only two numbers, ‘0’ and ‘1’, in a binary system for describing an arbitrary quantity made the fields of digital electronics and digital signal processing powerful and ubiquitous. Here, inspired by the binary concept, we propose to develop the notion of digital metamaterials. Specifically, we investigate how one can synthesize an electromagnetic metamaterial with a desired permittivity, using as building blocks only two elemental materials, which we call ‘metamaterial bits’, with two distinct permittivity functions. We demonstrate, analytically and numerically, how proper spatial mixtures of such metamaterial bits lead to elemental ‘metamaterial bytes’ with effective material parameters that are different from the parameters of the metamaterial bits. We then apply this methodology to several design examples of optical elements, such as digital convex lenses, flat graded-index digital lenses, digital constructs for epsilon-near-zero (ENZ) supercoupling and digital hyperlenses, thus highlighting the power and simplicity of the methodology. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4082.html 16.标题: Current-induced transition from p 标题:-by-p 标题: to concurrent intercalation in phase-separating battery electrodes AOP 作者:Yiyang Li, Farid El Gabaly, Todd R. Ferguson, Raymond B. Smith, Norman C. Bartelt, Joshua D. Sugar, Kyle R. Fenton, Daniel A. Cogswell, A. L. David Kilcoyne, Tolek Tyliszczak, Martin Z. Bazant & William C. Chueh 摘 要 : Many battery electrodes contain ensembles of nanoparticles that phase-separate on (de)intercalation. In such electrodes, the fraction of actively intercalating particles directly impacts cycle life: a vanishing population concentrates the current in a small number of particles, leading 63 to current hotspots. Reports of the active particle population in the phase-separating electrode lithium iron phosphate (LiFePO4; LFP) vary widely, ranging from near 0% (particle-by-particle) to 100% (concurrent intercalation). Using synchrotron-based X-ray microscopy, we probed the individual state-of-charge for over 3,000 LFP particles. We observed that the active population depends strongly on the cycling current, exhibiting particle-by-particle-like behaviour at low rates and increasingly concurrent behaviour at high rates, consistent with our phase-field porous electrode simulations. Contrary to intuition, the current density, or current per active internal surface area, is nearly invariant with the global electrode cycling rate. Rather, the electrode accommodates higher current by increasing the active particle population. This behaviour results from thermodynamic transformation barriers in LFP, and such a phenomenon probably extends to other phase-separating battery materials. We propose that modifying the transformation barrier and exchange current density can increase the active population and thus the current homogeneity. This could introduce new paradigms to enhance the cycle life of phase-separating battery electrodes. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4084.html 17.标题:Atomic structure and dynamic behaviour of truly one-dimensional ionic chains inside carbon nanotubes AOP 作 者 : Ryosuke Senga, Hannu-Pekka Komsa, Zheng Liu, Kaori Hirose-Takai, Arkady V. Krasheninnikov & Kazu Suenaga 摘要:Materials with reduced dimensionality have attracted much interest in various fields of fundamental and applied science. True one-dimensional (1D) crystals with single-atom thickness have been realized only for few elemental metals (Au, Ag) or carbon, all of which showed very short lifetimes under ambient conditions. We demonstrate here a successful synthesis of stable 1D ionic crystals in which two chemical elements, one being a cation and the other an anion, align alternately inside carbon nanotubes. Unusual dynamical behaviours for different atoms in the 1D lattice are experimentally corroborated and suggest substantial interactions of the atoms with the nanotube sheath. Our theoretical studies indicate that the 1D ionic crystals have optical properties distinct from those of their bulk counterparts and that the properties can be engineered by introducing atomic defects into the chains. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4069.html 18.标题: In situ detection of hydrogen-induced phase transitions in individual palladium nanocrystals AOP 作者:Andrea Baldi, Tarun C. Narayan, Ai Leen Koh & Jennifer A. Dionne 摘要:Many energy- and information-storage processes rely on phase changes of nanomaterials in reactive environments. Compared to their bulk counterparts, nanostructured materials seem to exhibit faster charging and discharging kinetics, extended life cycles, and size-tunable thermodynamics. However, in ensemble studies of these materials, it is often difficult to discriminate between intrinsic size-dependent properties and effects due to sample size and shape dispersity. Here, we detect the phase transitions of individual palladium nanocrystals during hydrogen absorption and desorption, using in situ electron energy-loss spectroscopy in an environmental transmission electron microscope. In contrast to ensemble measurements, we find that palladium nanocrystals undergo sharp transitions between the α and β phases, and that surface 64 effects dictate the size dependence of the hydrogen absorption pressures. Our results provide a general framework for monitoring phase transitions in individual nanocrystals in a reactive environment and highlight the importance of single-particle approaches for the characterization of nanostructured materials. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4086.html 19.标题: Ultrasoft microgels displaying emergent platelet-like behaviours AOP 作者:Ashley C. Brown, Sarah E. Stabenfeldt, Byungwook Ahn, Riley T. Hannan, Kabir S. Dhada, Emily S. Herman, Victoria Stefanelli, Nina Guzzetta, Alexander Alexeev, Wilbur A. Lam, L. Andrew Lyon & Thomas H. Barker 摘要:Efforts to create platelet-like structures for the augmentation of haemostasis have focused solely on recapitulating aspects of platelet adhesion1; more complex platelet behaviours such as clot contraction2 are assumed to be inaccessible to synthetic systems. Here, we report the creation of fully synthetic platelet-like particles (PLPs) that augment clotting in vitro under physiological flow conditions and achieve wound-triggered haemostasis and decreased bleeding times in vivo in a traumatic injury model. PLPs were synthesized by combining highly deformable microgel particles with molecular-recognition motifs identified through directed evolution. In vitro and in silico analyses demonstrate that PLPs actively collapse fibrin networks, an emergent behaviour that mimics in vivo clot contraction. Mechanistically, clot collapse is intimately linked to the unique deformability and affinity of PLPs for fibrin fibres, as evidenced by dissipative particle dynamics simulations. Our findings should inform the future design of a broader class of dynamic, biosynthetic composite materials. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4066.html 20.标题: Phase-engineered low-resistance contacts for ultrathin MoS2 transistors AOP 作者:Rajesh Kappera, Damien Voiry, Sibel Ebru Yalcin, Brittany Branch, Gautam Gupta, Aditya D. Mohite & Manish Chhowalla 摘 要 : Ultrathin molybdenum disulphide (MoS2) has emerged as an interesting layered semiconductor because of its finite energy bandgap and the absence of dangling bonds. However, metals deposited on the semiconducting 2H phase usually form high-resistance (0.7 kΩ μm–10 kΩ μm) contacts, leading to Schottky-limited transport. In this study, we demonstrate that the metallic 1T phase of MoS2 can be locally induced on semiconducting 2H phase nanosheets, thus decreasing contact resistances to 200–300 Ω μm at zero gate bias. Field-effect transistors (FETs) with 1T phase electrodes fabricated and tested in air exhibit mobility values of ~50 cm2 V−1 s−1, subthreshold swing values below 100 mV per decade, on/off ratios of >107, drive currents approaching ~100 μA μm−1, and excellent current saturation. The deposition of different metals has limited influence on the FET performance, suggesting that the 1T/2H interface controls carrier injection into the channel. An increased reproducibility of the electrical characteristics is also obtained with our strategy based on phase engineering of MoS2. 链接: http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4080.html 21. 标 题 : Entropy-driven formation of large icosahedral colloidal clusters by spherical confinement AOP 作者:Bart de Nijs, Simone Dussi, Frank Smallenburg, Johannes D. Meeldijk, Dirk J. Groenendijk, 65 Laura Filion, Arnout Imhof, Alfons van Blaaderen & Marjolein Dijkstra 摘要:Icosahedral symmetry, which is not compatible with truly long-range order, can be found in many systems, such as liquids, glasses, atomic clusters, quasicrystals and virus-capsids1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12. To obtain arrangements with a high degree of icosahedral order from tens of particles or more, interparticle attractive interactions are considered to be essential1, 3, 6, 7, 8, 9, 10, 11, 12. Here, we report that entropy and spherical confinement suffice for the formation of icosahedral clusters consisting of up to 100,000 particles. Specifically, by using real-space measurements on nanometre- and micrometre-sized colloids, as well as computer simulations, we show that tens of thousands of hard spheres compressed under spherical confinement spontaneously crystallize into icosahedral clusters that are entropically favoured over the bulk face-centred cubic crystal structure13, 14. Our findings provide insights into the interplay between confinement and crystallization and into how these are connected to the formation of icosahedral structures. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4072.html 22.标题:Giant bandgap renormalization and excitonic effects in a monolayer transition metal dichalcogenide semiconductor AOP 作者:Miguel M. Ugeda, Aaron J. Bradley, Su-Fei Shi, Felipe H. da Jornada, Yi Zhang, Diana Y. Qiu, Wei Ruan, Sung-Kwan Mo, Zahid Hussain, Zhi-Xun Shen, Feng Wang, Steven G. Louie & Michael F. Crommie 摘要:Two-dimensional (2D) transition metal dichalcogenides (TMDs) are emerging as a new platform for exploring 2D semiconductor physics1, 2, 3, 4, 5, 6, 7, 8, 9. Reduced screening in two dimensions results in markedly enhanced electron–electron interactions, which have been predicted to generate giant bandgap renormalization and excitonic effects10, 11, 12, 13. Here we present a rigorous experimental observation of extraordinarily large exciton binding energy in a 2D semiconducting TMD. We determine the single-particle electronic bandgap of single-layer MoSe2 by means of scanning tunnelling spectroscopy (STS), as well as the two-particle exciton transition energy using photoluminescence (PL) spectroscopy. These yield an exciton binding energy of 0.55 eV for monolayer MoSe2 on graphene—orders of magnitude larger than what is seen in conventional 3D semiconductors and significantly higher than what we see for MoSe2 monolayers in more highly screening environments. This finding is corroborated by our ab initio GW and Bethe–Salpeter equation calculations14, 15 which include electron correlation effects. The renormalized bandgap and large exciton binding observed here will have a profound impact on electronic and optoelectronic device technologies based on single-layer semiconducting TMDs. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4061.html 23.标题: Lateral heterojunctions within monolayer MoSe2–WSe2 semiconductors AOP 作者:Chunming Huang, Sanfeng Wu, Ana M. Sanchez, Jonathan J. P. Peters, Richard Beanland, Jason S. Ross, Pasqual Rivera, Wang Yao, David H. Cobden & Xiaodong Xu 摘要:Heterojunctions between three-dimensional (3D) semiconductors with different bandgaps are the basis of modern light-emitting diodes1, diode lasers2 and high-speed transistors3. Creating analogous heterojunctions between different 2D semiconductors would enable band engineering within the 2D plane4, 5, 6 and open up new realms in materials science, device physics and engineering. Here we demonstrate that seamless high-quality in-plane heterojunctions can be 66 grown between the 2D monolayer semiconductors MoSe2 and WSe2. The junctions, grown by lateral heteroepitaxy using physical vapour transport7, are visible in an optical microscope and show enhanced photoluminescence. Atomically resolved transmission electron microscopy reveals that their structure is an undistorted honeycomb lattice in which substitution of one transition metal by another occurs across the interface. The growth of such lateral junctions will allow new device functionalities, such as in-plane transistors and diodes, to be integrated within a single atomically thin layer. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4064.html 24.标题: Collective and individual migration following the epithelial–mesenchymal transition AOP 作者:Ian Y. Wong, Sarah Javaid, Elisabeth A. Wong, Sinem Perk, Daniel A. Haber, Mehmet Toner & Daniel Irimia 摘要:During cancer progression, malignant cells in the tumour invade surrounding tissues. This transformation of adherent cells to a motile phenotype has been associated with the epithelial–mesenchymal transition (EMT). Here, we show that EMT-activated cells migrate through micropillar arrays as a collectively advancing front that scatters individual cells. Individual cells with few neighbours dispersed with fast, straight trajectories, whereas cells that encountered many neighbours migrated collectively with epithelial biomarkers. We modelled these emergent dynamics using a physical analogy to phase transitions during binary-mixture solidification, and validated it using drug perturbations, which revealed that individually migrating cells exhibit diminished chemosensitivity. Our measurements also indicate a degree of phenotypic plasticity as cells interconvert between individual and collective migration. The study of multicellular behaviours with single-cell resolution should enable further quantitative insights into heterogeneous tumour invasion. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4062.html 25.标题:Direct observation of ferroelectric field effect and vacancy-controlled screening at the BiFeO3/LaxSr1 − xMnO3 interface AOP 作者:Young-Min Kim, Anna Morozovska, Eugene Eliseev, Mark P. Oxley, Rohan Mishra, Sverre M. Selbach, Tor Grande, S. T. Pantelides, Sergei V. Kalinin & Albina Y. Borisevich 摘要:The development of interface-based magnetoelectric devices necessitates an understanding of polarization-mediated electronic phenomena and atomistic polarization screening mechanisms. In this work, the LSMO/BFO interface is studied on a single unit-cell level through a combination of direct order parameter mapping by scanning transmission electron microscopy and electron energy-loss spectroscopy. We demonstrate an unexpected ~5% lattice expansion for regions with negative polarization charge, with a concurrent anomalous decrease of the Mn valence and change in oxygen K-edge intensity. We interpret this behaviour as direct evidence for screening by oxygen vacancies. The vacancies are predominantly accumulated at the second atomic layer of BFO, reflecting the difference of ionic conductivity between the components. This vacancy exclusion from the interface leads to the formation of a tail-to-tail domain wall. At the same time, purely electronic screening is realized for positive polarization charge, with insignificant changes in lattice and electronic properties. These results underline the non-trivial role of electrochemical phenomena in determining the functional properties of oxide interfaces. Furthermore, these 67 behaviours suggest that vacancy dynamics and exclusion play major roles in determining interface functionality in oxide multilayers, providing clear implications for novel functionalities in potential electronic devices. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4058.html 26. 标题:Redox shuttle mechanism enhances photocatalytic H2 generation on Ni-decorated CdS nanorods AOP 作者:Thomas Simon, Nicolas Bouchonville, Maximilian J. Berr, Aleksandar Vaneski, Asmir Adrović, David Volbers, Regina Wyrwich, Markus Döblinger, Andrei S. Susha, Andrey L. Rogach, Frank Jäckel, Jacek K. Stolarczyk & Jochen Feldmann 摘要:Photocatalytic conversion of solar energy to fuels, such as hydrogen, is attracting enormous interest, driven by the promise of addressing both energy supply and storage1. Colloidal semiconductor nanocrystals have been at the forefront of these efforts owing to their favourable and tunable optical and electronic properties2, 3, 4 as well as advances in their synthesis5, 6. The efficiency of the photocatalysts is often limited by the slow transfer and subsequent reactions of the photoexcited holes and the ensuing high charge recombination rates. Here we propose that employing a hydroxyl anion/radical redox couple to efficiently relay the hole from the semiconductor to the scavenger leads to a marked increase in the H2 generation rate without using expensive noble metal co-catalysts. The apparent quantum yield and the formation rate under 447 nm laser illumination exceeded 53% and 63 mmol g−1 h−1, respectively. The fast hole transfer confers long-term photostability on the system and opens new pathways to improve the oxidation side of full water splitting. 链接:http://www.nature.com/nmat/journal/vaop/ncurrent/full/nmat4049.html 九、IQPC 最新国防会议(Defence) (来源:http://www.iqpc.com/) 1. 会议名称:Military E-Learning and Smart Devices 会议时间:October 21-23, 2014 会议地点:Charing Cross - A Guoman Hotel , London, United Kingdom 会议简介:Introducing the only conference dedicated to the military use of smart devices for e-learning and simulation outside of North America Due to overwhelming demand, we are holding our inaugural Military E-Learning & Smart Devices Conference, to support you – the pioneers using e-learning, simulation techniques & smart devices for the training of military personnel. This tri-service event will provide you with the opportunity to share best practice in what remains a relatively new and innovative side of defence capability. Over the last ten years, a number of militaries have taken advantage of the substantial R&D spending by technology companies, and the subsequent uptake of smart devices in the civilian sphere. A soldier can review a lesson in an online drive or portal, complete an assignment with teammates 68 online, or attend a class via video link, all from their tablet, smartphone or desktop. The fact that service personnel are commercial users of this software should be no impediment to the military as apps can be (and have been) created to help assist with mobile learning and development, enabling students to learn on their own watch. Additionally, with the growth in the use of simulation and virtual reality exercises for pre-deployment cultural awareness training, judgement shooting, and scenario-based practice mission planning, militaries truly are riding the wave of the latest tech bubble. With a process of trial and error typifying the military’s approach thus far, there is still a substantial debate to be had as to how the defence community maximises the educational and operational benefits of this technology for their personnel’s development and performance. 论文提交:http://www.militarysmartdevices.com/ 2. 会议名称:Future Mortar Systems 2014 会议时间:28 - 30 October, 2014 会议地点:-Kensington Close Hotel, London, United Kingdom 会议简介:Exploring cost-effective, yet meticulous solutions to enhance future mortar capability Defence IQ is delighted to announce the return of our annual Future Mortar Systems Conference.
