Journal ArticleDOI
Study of Amorphous Carbon Nitride Films Aiming at White Light Emitting Devices
Yuta Iwano,Toshiaki Kittaka,Hidekazu Tabuchi,Masaya Soukawa,Shinsuke Kunitsugu,Kenichi Takarabe,Kunio Itoh +6 more
TL;DR: In this article, the possibility of white light emitting devices using carbon nitride (CNx) thin films has been studied, and it was concluded that the red peak originates from the level relating to H atom and blue peak from C-N bonds.
Journal ArticleDOI
High-pressure X-ray structural study of BeO and ZnO to 200 GPa
TL;DR: In this paper, the phase transition of BeO from the wurzite to the NaCl structure and that of ZnO from NaCl to the CsCl structure was investigated.
Journal ArticleDOI
Significant enhancement of thermoelectric properties and metallization of Al-doped Mg2Si under pressure
Natalia V. Morozova,Sergey V. Ovsyannikov,Sergey V. Ovsyannikov,Igor V. Korobeinikov,Alexander E. Karkin,Kenichi Takarabe,Yoshihisa Mori,Shigeyuki Nakamura,Vladimir V. Shchennikov +8 more
TL;DR: In this paper, the results of investigations of electronic transport properties and lattice dynamics of Al-doped magnesium silicide (Mg2Si) thermoelectrics at ambient and high pressures to and beyond 15 GPa were reported.
Journal ArticleDOI
Thermoelectric and electrical transport properties of Mg2Si multi-doped with Sb, Al and Zn
Jianbao Zhao,Zhenxian Liu,Joel Reid,Kenichi Takarabe,Tsutomu Iida,Bosen Wang,Uwatoko Yoshiya,John S. Tse +7 more
TL;DR: In this paper, the electrical transport properties of Mg2Si-based thermoelectric materials have been determined from mid-infrared reflectivities, Hall effect and conventional quasi-four probe conductivity measurements.
Journal ArticleDOI
Safety, efficacy, and quality control of a photoelectric dye-based retinal prosthesis (Okayama University-type retinal prosthesis) as a medical device.
TL;DR: The prototype, using a photoelectric dye-coupled polyethylene film, could induce intracellular calcium elevation in photoreceptor-lacking embryonic retinal tissues and cultured retinal neurons and led to vision recovery as proved by a behavior test.
