Lethal effects of blue light on insects

NEXT
PREV
特徴・独自性
  • We revealed the strong lethal effect of short-wavelength visible light (blue light: 400–500 nm) on insects. That is, we found that blue light irradiation by using a common light-emitting diode (LED) can kill the eggs, larvae, pupae, and adults of various orders of insects. Our findings will provide clean and safe pest-control technique as well as important information on the hazards of exposure to visible light.

Chemical Recycling of Problematic Polymeric Wastes

NEXT
PREV
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.

Development of Compound Semiconductor Radiation Detectors

NEXT
PREV
特徴・独自性
  • The main research subject of our group is developing material purification methods, crystal growth methods and detector fabrication technologies for compound semiconductor radiation detectors. Our group intensely studies a compound semiconductor, thallium bromide (TlBr), for fabrication of gamma-ray detectors for the advanced radiation applications. The attractive physical properties of TlBr lie in its high atomic number (Tl: 81, Br: 35), high density (7.56 g/cm3) and wide bandgap (2.68 eV). Due to the high atomic number and high density, TlBr exhibits high photon stopping power. The wide bandgap of TlBr permits the device low-noise operation at and above room temperatures.

Our group focuses on development of compound semiconductor radiation detectors for advanced radiation applications including ultra-high resolution PET systems, ultra-high resolution SPECT systems, photon counting CT systems and Compton cameras. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry.

X-Ray Phase Imaging for High-Sensitive Non-Destructive Testing

NEXT
PREV
特徴・独自性
  • Conventional X-ray imaging methods that rely on X-ray attenuation cannot generate clear contrast in the observation of low-density materials such as polymers consisting of low-Z elements. However, the sensitivity to the materials can be improved drastically by X-ray phase imaging that detects X-ray refraction caused by the materials. X-ray Talbot or Talbot-Lau interferometry consisting of X-ray transmission gratings is now constructed in laboratories for X-ray phase imaging. X-ray phase tomography is also realized, enabling high-sensitive three-dimensional observation.
  • X-ray phase imaging can be utilized for X-ray non-destructive testing of industrial products and baggage that cannot be checked conventionally.
実用化イメージ

We aim at appending a phase-contrast mode to micro-CT apparatuses and developing screening apparatuses in production lines.

Advanced die casting process computing with solidification phenomena

NEXT
PREV
特徴・独自性
  • Die casting is a method of mass-producing high-precision castings in a short time by filling the mold with molten metal at high pressure and high speed. Since solidification is completed quickly under high pressure, various defects peculiar to die casting occur. Significantly, the casting cavity has a high incidence in die casting, and it is a factor that hinders the quality. Therefore, a numerical approach to the die casting process is expected to prevent these problems, and the information obtained from the numerical analysis is expected to be reflected in the casting plan to reduce the number of prototypes, the lead time to product development, and the cost. In this study, a multiphase flow analysis with solidification phenomena of molten aluminum inside mold was conducted for a high-pressure die casting process of the throttle body.

A conventional PCM is Ge-Sb-Te which shows a fast crystallization speed and an excellent reversibility of phase transition. However, Ge-Sb-Te has a low crystallization temperature of about 150 ºC and a high melting temperature of over 600 ºC , which limits data retention and causes high power consumption, respectively.
  • We have developed a new phase change materials with high crystallization temperature and low melting point such as Ge-Cu-Te etc, which have high potential as PCRAM materials with high thermal stability and low power consumption (Fig.1,2).

  • In Japan, the percentage of elderly people aged 65 years or over was 23.1% in 2010. It is no doubt that Japan is the world's first super-aging society. In such a super-aging environment, it is necessary to form a society in which each individual can play an active role even as one becomes older in order to maintain and improve the quality of life of all people and to maintain a healthy society. In advanced brain science, research from the fields of brain function imaging, cognitive science, and psychology has been utilized with the aim of realizing a healthy aging society. Up to date information on various new technologies and related discoveries has been disseminated so that individuals can live a healthy life with peace of mind at every stage of aging, while maintaining and improving the health of their brain and mind in a diverse and complex society.
