Economics of Aging

特徴・独自性
  • I investigate on the economics of aging, the optimal social welfare policy, low fertility and so on not based on the historical and systematic approach but based on the neo-classical economic theory. I also use econometric method and statistical approach. I often estimate the future projections of the population, public finance, magnitude of private markets, the results of public policies.
  • I also research on the comparative studies on East Asia (Japan, China, Korea, Taiwan) and European (especially Scandinavian countries). I provide statistic data and information on the economic and political systems on the aging in Japan.
実用化イメージ

The future estimation on the financial status , market caused by low fertility and aging. The effective management of the medical institutions, social welfare systems, gender equality societies for the central and local government, research institutions, public enterprises, and financial Institutions.

特徴・独自性
  • Spintronics is a technology utilizing electron spin which provided magnetic sensor, nonvolatile magnetic memory, and so on. Our studies are as below.
  • Noble & Rare-earth free magnetic films with large perpendicular magnetic anisotropy. We achieved to develop various Mn-bases alloy films exhibiting high perpendicular magnetic anisotropy (Fig.1 ).
  • THz range observation of magnetization motion. We achieved to detect a motion of magnetization using pulse laser in time domain (Fig. 2).
  • Novel organic spin devices. We achieved to fabricate hybrid junction consisting of an organic layer sandwiched by two inorganic magnetic layers and to observe magnetoresistance effect.
  • Tunnel Magnetoresistive devices: We are developing TMR devices with Mn-Ga alloys films (Fig.3 ).

[PVC]

Chemical Recycling of Problematic Polymeric Wastes

特徴・独自性
  • The Yoshioka Laboratory works on the recycling of various polymers by thermal and wet processes. Plastics such as poly(ethylene terephthalate) (PET), polyvinyl chloride (PVC), and high impact polystyrene (HIPS) cause serious problems during their recycling for the recycling process and the environment. However, these materials can also be seen as a resource for new materials. The decarboxylation of PET results in high yields of benzene that can be used as a chemical feedstock. Another important feature is the dehalogenation of flame retarded plastics and PVC. Dechlorinated plastic waste can be an important source for hydrocarbons, which can be used as fuels and chemical feedstock. The chemical modification of PVC offers the possibility of new materials with new properties. Modified PVC can be used as antibacterial material or as a material with ion exchange properties. The removal of brominated flame retardants from HIPS leads to higher recovery rates of styrene during thermal processing. When a wet process is used, the resulting flame retardant free HIPS can be reused.
実用化イメージ

We are eager to help companies to overcome their problems during recycling and recovery, and provide solutions for the treatment of waste materials.
