摘要: Platinum ion doped magnetic TiO2 (Fe3O4@SiO2@Pt-ion-TiO2) hybrid microspheres with
uniform magnetic cores were synthesized and characterized in this work. The results indicate that
the photoactivity of Fe3O4@SiO2@Pt-ion-TiO2 is much higher than Fe3O4@SiO2@TiO2 for
the decolorization of acid orange 20 under UV-visible light irradiation. The trend for the final
degradation ratio with Fe3O4@SiO2@Pt-ion-TiO2 is quite small, even after seven repetitive
experiments. These data indicate that the magnetic microspheres possess the potential to be
effective and stable catalysts. The results demonstrate that the Pt ion doped magnetic catalyst
meets the needs for both immobilization and high photoactivity. (C) 2013 Elsevier B.V. All rights

摘 要 : A two-step esterification process is developed for the synthesis of
epoxy-acrylic-grafted-copolymer waterborne resins. The effect of synthesis parameters on water
and corrosion resistance of the waterborne coatings is investigated. The results reveal that
moderate increasing of the resin molecular weight (<8000 Da) and carboxyl content (<27 wt.%)
increased the crosslinking property, thereby improved the anticorrosion performance of the
coatings. Longer epoxy-octanoic hydrophobic chains can provide stronger shielding effect on the
hydrophilic portion of the polymer matrixes. The polar group content in a waterborne resin can be
optimized for better anticorrosion performance, whereas the optimal value is coating-specific. (c)

摘 要 : Sequential interpenetrating polymer networks (IPN) hydrogels based on konjac
glucomannan (KGM) and poly(methacrylic acid) (PMAA) were prepared by immersion of a
solution of methacrylic acid (MAA) monomer with cross-linker N,N'-methylenebisacrylamide
(MBAAm) and initiating into a pre-fabricated dried KGM gel. Polymerization and cross-linking
of MAA inside the KGM network resulted in a novel biodegradable pH-sensitive IPN hydrogel.
The studies on the swelling behavior of IPN hydrogels reveal their sensitive response to
environment pH value. It was possible to modulate the degree of swelling of the IPN gels by
changing the KGM/PMAA ratio and the cross-linking density of the PMAA component. The
KGM component in the IPN can be degraded by beta-glycosidase Mannaway25L. In vitro drug
release behavior of IPN hydrogels were investigated under different environments using model
drugs 5-fluorouracil. The results suggested that such an IPN hydrogel can be exploited as carrier
candidate for colon-specific drug delivery. (C) 2013 Elsevier Ltd. All rights reserved.

摘 要 : In this study, tropical cyclones over the East and South China Seas were found to be the
most predominant weather conditions associated with the occurrence of high ozone (O-3) episodes
in Hong Kong in 2005-2009. A photochemical trajectory model coupled with Master Chemical
Mechanism (MCM) was adapted to simulate the O-3 concentrations during two O-3 pollution
episodes. The results agreed well with the observed data. A representative backward air mass
trajectory was used to determine the contribution of each volatile organic compound (VOC) to the
O-3 levels. After taking into account both reactivity and mass emission of each VOC, 10 species
were found to be the key O-3 precursors in Hong Kong. Further analysis identified solvent related
products accounting for 70% of the modeled O-3 concentration in Hong Kong. The results
highlight the importance of considering together reactivity and source sector emissions in
developing targeted VOC reduction for O-3 abatement strategies. (C) 2013 Elsevier Ltd. All rights

标 题 : Effects of Adsorbed F, OH, and Cl Ions on Formaldehyde Adsorption Performance and
Mechanism of Anatase TiO2 Nanosheets with Exposed {001} Facets

摘要: Formaldehyde (HCHO), as the main indoor air pollutant, is highly needed to be removed by
adsorption or catalytic oxidation from the indoor air. Herein, the F-, OH-, and Cl--modified
anatase TiO2 nanosheets (TNS) with exposed {001} facets were prepared by a simple
hydrothermal and post-treatment method, and their HCHO adsorption performance and
mechanism were investigated by the experimental analysis and theoretical simulations. Our results
indicated that the adsorbed F-, OH-, and Cl- ions all could weaken the interaction between the
HCHO and TNS surface, leading to the serious reduction of HCHO adsorption performance of
TNS. However, different from F- and Cl- ions, OH- ion could induce the dissociative adsorption
of HCHO by capturing one H atom from HCHO, resulting in the formation of one formyl group
and one H2O-like group. This greatly reduced the total energy of the HCHO adsorption system.
Thus, the adsorbed OH- ions could provide the additional active centers for HCHO adsorption. As
a result, the NaOH-treated TNS showed the best HCHO adsorption performance mainly because
its surface F- was replaced by OH-. This study will provide new insight into the design and
fabrication of high performance adsorbents for removing indoor HCHO and, also, will enhance
the understanding of the HCHO adsorption mechanism.

标 题 : UV-B resistance as a criterion for the selection of desert microalgae to be utilized for
inoculating desert soils

摘 要 : The adaption capability of microalgae species to intense UV-B radiation is an important
feature for their survival under the harsh growth conditions they have to face when used for
inoculating unconsolidated sand soils in desert areas. In this study, the responses of photosynthetic
activity, reactive oxygen species (ROS) generation, and DNA strand breaks to UV-B radiation in
four microalgae isolated from artificially induced biological soil crusts were investigated. It was
found that low UV-B doses easily inhibited the photosynthetic activity and induced serious DNA
damage in Chlorella vulgaris. Microcoleus vaginatus showed the capability to withstand only
moderate doses of UV-B, while Nostoc was capable of facing high doses of UV-B due to its lower
generation of ROS and higher capability to repair photosystem II (PSII) and DNA damages. On
the other hand, Scytonema javanicum showed additional strategies to survive UV-B irradiance,
namely the closure of PSII when ROS generation increased rapidly, in addition to a high repair
ability of PSII and DNA damage. The results obtained point out different resistance and defense
mechanisms of the four microalgae in response to UV-B irradiance and suggest that the strain of
Nostoc sp. tested is the most suitable for surviving under the high UV irradiation levels typical of
desertified areas.

摘要: Decolorization of Orange II by a ferrous sulfite system in aqueous solutions under a xenon
lamp (350W) was investigated to determine the enhancement of decolorization efficiency under
UV-vis irradiation. Orange II (10 mg L-1) was efficiently decolorized at an initial pH of 6.1 under
irradiation (84% efficiency at 60 min), whereas only 15% efficiency was achieved without
irradiation. Although 4 was the optimum pH for enhancing the decolorization rate by irradiation,
the enhancement was more significant at an initial pH near neutral. Concentration ratios of Fe(II)
to sulfite higher than the optimum ratio (about 1:10) could inhibit the decolorization rate via the
scavenging effect of sulfate or hydroxyl radicals. Semibatch experiments with multiple additions
of Fe(II), sulfite, and Fe(II)-sulfite, respectively, showed that sulfite was more important in
improving the decolorization efficiency of Orange II at higher concentration. However, removal of
total organic carbon during the semibatch reaction by the Fe(II)-sulfite system under irradiation
was as poor (<10%) as that without irradiation. This result implies that the conjugated
chromophore in Orange II was partly but easily transformed into achromatic products mainly
through electron transfer with sulfate radicals. In conclusion, UV-vis irradiation could greatly
accelerate the decolorization of Orange II solutions by Fe(II)-sulfite system, and extend the initial
working pH to near-neutral values. These attributes make the light-coupled Fe(II)-sulfite system a
more powerful system (i.e., photo-Fe(II)-sulfite system) for the decolorization of Orange II

摘 要 : Ordered rutile TiO2 nanorods grown on transparent electro-conductive F-doped
SnO2-coated (FTO) glass substrates were prepared by a simple hydrothermal method using
tetrabutyl titanate as the precursor and then calcined at various temperatures. The prepared
SnO2/TiO2 composite film samples were characterized by X-ray diffraction (XRD), scanning
electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron
spectroscopy (XPS). The photoelectrocatalytic (PEC) activity was evaluated by PEC degradation
of methylene blue (MB) aqueous solutions under UV-LED light irradiation. The results showed
that rutile TiO2 nanorods with diameters of ca. 300-700 nm and lengths of ca. 5 mu m vertically
grew on the FTO substrate. The resulting rutile TiO2 arrays exhibited excellent stability upon
annealing in a temperature range of 300-500 degrees C. The sample calcined at 400 degrees C
exhibited the highest PEC activity due to the combined effects of several factors including its
one-dimensional morphology, high crystallinity, close contact between the TiO2 nanorods and
SnO2 layers, SnO2/TiO2 n-n heterojunction and the applied external electrostatic field. The
proposed enhanced PEC mechanism was further confirmed by the transient photocurrent response
and electrochemical impedance spectroscopy (EIS) experiments.

摘 要 : The quality of certain plants is considered to be a key factor affecting the food habitat or
migration of some herbivorous species, and, thus, to estimate the spatial and temporal variation of
plant quality is crucial for understanding the grazing and migrating behaviours of these herbivores.
This study aimed to explore the possibilities of estimating plant protein and phosphorus contents,
with the laboratory-based hyperspectral measurements of fresh Carex leaves, which are the main
food source of many wintering bird species in Poyang Lake, China. Fifty-four Carex leaf samples
were collected, and their hyperspectral reflectance (at 350-2500nm) and crude protein and
phosphorus contents were measured in the laboratory. The successive projections algorithm (SPA)
was applied for spectral dimension reduction, and a multiple linear regression model was
calibrated to estimate the crude protein and phosphorus contents from the wavelengths selected
with the SPA. The model validation results showed that the root mean square errors (RMSEs) of
estimation were 2.51% for crude protein and 0.06% for phosphorus. Compared with a multiple
linear model with randomly selected inputs and full-spectrum partial least-square regression
(PLSR), the multiple linear regression model combined with the SPA method exhibited a
significant advantage in terms of accuracy in estimating the crude protein and phosphorus contents
of Carex leaves.

silicon

摘要: The electrochemical reduction of solid silica has been investigated in molten CaCl2 at 900
degrees C for the one-step, up-scalable, controllable and affordable production of nanostructured
silicon with promising photo-responsive properties. Cyclic voltammetry of the metallic cavity
electrode loaded with fine silica powder was performed to elaborate the electrochemical reduction
mechanism. Potentiostatic electrolysis of porous and dense silica pellets was carried out at
different potentials, focusing on the influences of the electrolysis potential and the microstructure
of the precursory silica on the product purity and microstructure. The findings suggest a potential
range between -0.60 and -0.95 V (vs. Ag/AgCl) for the production of nanostructured silicon with
high purity (>99 wt%). According to the elucidated mechanism on the electro-growth of the
silicon nanostructures, optimal process parameters for the controllable preparation of high-purity
silicon nanoparticles and nanowires were identified. Scaling-up the optimal electrolysis was
successful at the gram-scale for the preparation of high-purity silicon nanowires which exhibited
promising photo-responsive properties.
