Autor: Daisuke Tashima, Takuhiro Kashio, Takuya Eguchi, Seiji Kumagai, Toshiki Tsubota, John D.W. Madden

Publikováno v: Materials Letters: X, Vol 18, Iss , Pp 100193- (2023)

In this study, a method was developed for the management of marine plastic waste via the production of activated carbon. The specific surface area, micropore volume, and mesopore volume of marine-plastic-based activated carbon prepared at selected te

Publikováno v: AIP Advances, Vol 13, Iss 2, Pp 025001-025001-5 (2023)

We previously proposed the idea that the effective thermal-energy transfer from the phonon system to the spin system in liquid phase epitaxial (LPE) films of Bi-substituted yttrium iron garnet (Bi:YIG), a ferrimagnetic insulator, takes place through

Enhancement of the spin Seebeck effect owing to bismuth substitution in thermoelectric generators fabricated from LPE Bi-substituted YIG films

Autor: Masaaki Imamura, Hironori Asada, Ryo Nishimura, Keita Yamaguchi, Daisuke Tashima, Jiro Kitagawa

Publikováno v: AIP Advances, Vol 11, Iss 3, Pp 035143-035143-5 (2021)

Raising the thermoelectric voltage in spin thermoelectric generators is an important subject. We investigated the substitution of bismuth for yttrium to increase spin pumping at the paramagnetic metal and ferrimagnetic insulator (PM/FMI) interface, a

Magneto-optical properties of wider gap semiconductors ZnMnTe and ZnMnSe films prepared by MBE

Autor: Masaaki Imamura, Daisuke Tashima, Jiro Kitagawa, Hironori Asada

Publikováno v: Journal of Electronic Science and Technology, Vol 18, Iss 3, Pp 100056- (2020)

The II-VI based magnetic semiconductors with a direct and wide optical bandgap are expected to show high potential for optical applications utilizing short wavelength laser diodes (LDs), such as 532-nm green and 475-nm blue LDs. We have confirmed tha

Effect of Ball Milling on the Electrochemical Performance of Activated Carbon with a Very High Specific Surface Area

Autor: Takuya Eguchi, Yugo Kanamoto, Masahiro Tomioka, Daisuke Tashima, Seiji Kumagai

Publikováno v: Batteries, Vol 6, Iss 2, p 22 (2020)

Activated carbon (AC) with a very high specific surface area of >3000 m2 g−1 and a number of course particles (average size: 75 µm) was pulverized by means of planetary ball milling under different conditions to find its greatest performances as t
