Synthesis and properties of a series of bio-based surfactants with different hydrophobic chain length

Sato S., Habe H., National Institute of Advanced Industrial Science and Technology (AIST), JP

Glyceric acid (2,3-dihydroxypropanoic acid, GA) is a natural organic compound found in specific plants as a minor constituent, but can be mass-produced biotechnologically from glycerol, a by-product of biodiesel fuel production. We synthesized a series [...]

Cell adhesion behaviors on polyethylene terephthalate surface modified by surface-wave plasma-initiated graft polymerization

Nina A., Ishizaki T., Saito N., National Institute of Advanced Industrial Science and Technology (AIST), JP

For better performance in biomedical applications, the PET surface still needs to be improved by functionalization, particularly controlling the hydrophilicity. In order to impart hydrophilicity to the PET surface, we tried to introduce acrylic acid [...]

On-demand release of corrosion-inhibiting molecules from layerd double hydroxide film formed on magnesium alloy

Ishizaki T., Teshima K., Saito N., National Institute of Advanced Industrial Science and Technology (AIST), JP

Magnesium is one of the lightest engineering materials. Thus, it is expected that magnesium and its alloys are applied to aerospace, aircraft, automobile, and railway. However, they have a defect which is extremely low corrosion [...]

Comprehensive Approach for Nanotechnology R&D and Public Engagement

Sekiya M., Ishizu S., An S., Tanabe T., Ata M., National Institute of Advanced Industrial Science and Technology (AIST), JP

AIST has participated in the research project “Development of comprehensive database index for a basis of facilitation of nanotechnology R&D” with the University of Tokyo and National Institute for Materials Science since September 2007. In [...]

Bridge a Gap between Nanotechnology R&D, Business and Public

Sekiy M., An S., Ishizu S., National Institute of Advanced Industrial Science and Technology (AIST), JP

I outline a new research project “Research on use of information and communication for facilitating public acceptance”. This project is one of the research components in a new research program “Developing knowledge-based platform to support [...]

Device Parameter Extraction from Fabricated Double-Gate MOSFETs

Tsutsumi T., Liu Y., Nakagawa T., Sekigawa T., Hioki M., Suzuki E., Koike H., National Institute of Advanced Industrial Science and Technology (AIST), JP

Accurate spice simulation needs parameter extraction of the fabricated DG-MOSFETs with good electrical characteristics. However, it is very difficult to fabricate such good DG-MOSFETs, so that device parameter extraction of the fabricated DG-MOSFETs has been [...]

Compact Model for Ultra-Short Channel Four-Terminal DG MOSFETs for Exploring Circuit Characteristics

Nakagawa T., Sekigawa T., Tsutsumi T., Hioki M., Suzuki E., Koike H., National Institute of Advanced Industrial Science and Technology (AIST), JP

We have proposed a compact model of the DG MOSFETs which handles two gates independently. The model can simulate the DG MOSFETs of asymmetric gate design, together with their four-terminal operation. In this report, we [...]

Thermal and Morphological Study of a New Type of Nanocomposites: Functionalized PP / PA / Clay Nanocomposites

Oyama H.T., Oono Y., Nakayama K., National Institute of Advanced Industrial Science and Technology (AIST), JP

In the present work we explore a new type of nanocom- posite, in which clay is distributed in a multi-phase polymer system. Our nanocomposites consist of an immiscible polymer pair, polypropylene grafted with maleic anhydride [...]
