Goal of the Talk:
～ Giant revolution of manufacturing of nanomaterials. The on-going integration of nanotechnology is expected to bring
innovations in broad, ranging areas that will revolutionize worldwide.
～Cutting Edge Research Accomplishments for leading Nanotechnology to Overcome Humanity’s Top Ten Problems in the Next
50 Years～
Technical Issues:
In this respect, the beginning of the 21 st century gave way to a new array of synthetic methods which greatly broadened the
possibilities even more.
Recently, El-Safty and Co-workers designed of nanopackages-based mesocage mosaic, core/double-shell, nanosheets, hollow
sphere, and nanowires metal oxides for wide-range projects in Japan to protect human health and improve the environmental
quality as follows:
1) Environmental clean-up systems: air, water and soil
2) Solar energy (PV) & energy storage
3) Healthcare and drug delivery system from tuberculosis (TB), HCV, anemia, and cancer
4) Green Fuel Production
5) Nano-water drinking station (40 tone/hour)
Based on this technology, NNT.Co.Ltd, (Register No. 0500-01-038108) JAPAN is established and funded from
Japanese government to help decontamination at Fukushima using mass-scale sensor/captor nanomaterials in water
station and household. Our NANO- Sensor / Monitor/ filter could be used as rapid early warning, monitoring,
sensing and decontamination of low doses of Radionuclides and hazardous. Our technological process offered (i)
Simple, (ii) cost-effective operation; (iii) massive tones product/hr, (iv) sustainable and (v) controlled waste
management. This technology show inhibited hazardous effects in human blood by preventing of the health risks such
as anemia or cancer (Scheme 1).
Technical Issues:
1) Our decontamination is cyclical (20 times), enabling solution for waste management based:
1) Volume reduction of waste materials,
2) Simple-used process for remediation
3) Recovering the toxins by cleanup the filters from toxins
4) Stability under thermal, mechanical and boiling water
Commercialization feasibility:
1) The cost-effective, mass-scale (1 tone/hour) of our materials in one factory at JAPAN, leading to feasible
decontamination of 40 tons water at once
2) Hand and safe-use pellet sets can be used to eliminate the threat of water and air from hazardous in home or nuclear
plants (scheme 2)
3) Cost-effective, reusable, durable materials. However, No Reverse Osmosis needed anymore, leading to reduce the
power used energy for operation with 2/3 price of normal station.
Marketing and Demands
Large-Volume of Groundwater & Surface Water plants (Water-Free Radiation
Feasibility of our nano-sensor design offers:
a) Early warning sensor of nuclear explosion and contamination
b) Radiation decontamination of >>99%
c) Get pure drinking water at nano-scale level of remediation (ng/L).
d) The produced nanowater has >> 1000 times free-toxins than that requested by WHO
Filters for home services or small-sector of business:
1) Visual indication, 2) Reusable filter
2) Cost-effective filer & water produced& High quality water (Scheme 3).
Our main interest is not only to make nanotechnological designs-based nanomaterials but also to reduce the production cost and to
expand their potential on-site and real-time measurements. We expected this nanopackage materials and designs can revolutionize
the consumer and industrial market in environmental pollution monitoring, transportation, security, defense, space missions,
energy, agriculture, and medicine [9-13]. Just to give an account of the importance of nanomaterials based save-drinking water

technology, the journal of Public Science recently appointed the development of our technology as one of the runners-up for the
“Scientific Breakthrough of 2012”.
