- - Developed bio-based polyimides from bioavailable aromatic diamines, which were photodimers of cinnamon-related molecules derived from genetically-manipulated microorganisms
- - Developed transparent biopolyimide film, which showed ultrahigh thermal resistance over the melting temperature of lead-free solders (390°C), the highest value of all bio-based plastics reported thus far
Invention of a new catalyst that can release electrons from hydrogen gas
- As part of the CREST Strategic Basic Research Program, Professor OGO Seiji and his research group (Kyushu University) have successfully developed a Nickel-Iron Catalyst with mimicking Nickel-Iron Hydrogenase, a hydrogen activation enzyme that exist naturally, as a model, and they have found that even iron, a common metal, could activate hydrogen at normal pressure and temperature in substitution for a noble metal, Ruthenium. It is anticipated that this technique can be applied to develop the precious metal-free fuel cell catalyst.
High-Voltage Vacuum Power Switch for Smart Power Grids
- As part of the Strategic Basic Research Program within the Advanced Low Carbon Technology Research and Development Program (ALCA), Chief Senior Researcher TAKEUCHI Daisuke (National Institute of Advanced Industrial Science and Technology, AIST) and his research group have successfully fabricated vacuum power switches rated at 10kV, building electron emitters from hydrogen-terminated diamond, whose negative-electron affinity enables it to supply a great deal of current across a strong vacuum when it is turned on. We also calculated that the technology could be scaled up to 100kV or greater, making the approach a promising one to control smart grids.
Mitsubishi Chemical Corporation aims for practical application of organic thin-film solar cells with energy efficiency ratio in excess of 10% in Spring 2013.
- As part of the ERATO Nakamura Functional Carbon Cluster Project, in addition to designing the molecular structure of organic molecules, Professor NAKAMURA Eiichi of the University of Tokyo has succeeded in forming a laminate structure at the nano-level, in order to create organic thin-film solar cells. Further joint research will be conducted with Mitsubishi Chemical Corporation based on this research, aiming at further successful technical development.
Successful creation of high performance solar cells using a liquid silicon coating process
Revolutionary method developed for manufacturing silicon thin-film solar cells, aimed at potential commercial applications.
- Assisted by ERATO, Professor SHIMODA Tatsuya of the Japan Advanced Institute of Science and Technology (JAIST) has successfully created high-performance organic thin-film solar cells using a liquid silicon coating process. This represents the first ever creation of an amorphous (non-crystalline) silicon thin film possessing semi-conductive properties. The coating process has enabled trial manufacture of p-i-n thin-film solar cells, with demonstrably high performance.
