Autor: Kazutaka Ikeda, Hidetoshi Ohshita, Toshiya Otomo, Kouji Sakaki, Hyunjeong Kim, Yumiko Nakamura, Akihiko Machida, Robert B. Von Dreele
Publikováno v: Journal of Applied Crystallography. 55:1631-1639
In situ gas-loading sample holders for two-dimensionally arranged detectors in time-of-flight neutron total scattering experiments have been developed to investigate atomic arrangements during deuterium absorption using time and real-space resolution

The hydrogen desorption and absorption reactions of the complex metal hydride NaAlH4 are disproportionation processes, and the kinetics can be improved by adding a few mol% of Ti compounds, although the catalytic mechanism, including the location and

Completely Elastic Deformation of Hydrogenated Ta Thin Films
Autor: Lars J. Bannenberg, Larissa Blom, Kouji Sakaki, Kohta Asano, Herman Schreuders
Publikováno v: ACS Materials Letters, 5(4)
Nanostructured metal hydrides could play a key role in a hydrogen economy. The nanostructuring or confinement of these materials as, e.g., thin films significantly affects the structural and functional properties. For tantalum hydride, a versatile hy

Publikováno v: Inorganic Chemistry. 60:17715-17721
The stability of a zirconium (Zr)-substituted face-centered cubic (FCC) yttrium (Y) hydride (Y1-xZrx hydride) phase was investigated experimentally and theoretically. Two possible sites for hydrogen atoms exist in the FCC structure, namely, T- and O-

Tuning the hydrogenation properties of Ti1+Cr2-Mn laves phase compounds for high pressure metal-hydride compressors
Autor: Kouji Sakaki, Véronique Charbonnier, Hyunjeong Kim, Hirotoshi Enoki, Kohta Asano
Publikováno v: International Journal of Hydrogen Energy. 46:36369-36380
Ti1+yCr2-xMnx compounds with a hexagonal MgZn2-type structure were investigated for their potential use in metal-hydride (MH) compressor applications. Here, the targeted MH compressor should absorb hydrogen below 30 MPa at 30 °C and desorb hydrogen
