X-Ray Powder Diffraction study of CS2 at high pressures
Journal of Physics: Condensed Matter, 2002Co-Authors: Yuichi Akahama, Y Minamoto, Haruki KawamuraAbstract:X-Ray Powder Diffraction experiments were performed at pressures up to 14 GPa and at room temperature. The orthorhombic lattice was retained at pressures up to 10 GPa. Above 10 GPa, however, a broad glassy background developed. The lattice constants, a, b, c, and the orientation angle at 2.72 GPa are 5.845, 5.220, 8.296 A and 41.3°, respectively. The orientation angle at high pressure is smaller than that of the low-temperature phase.

X-Ray Powder Diffraction from solid deuterium
Journal of Physics: Condensed Matter, 2002Co-Authors: Haruki Kawamura, Yuichi Akahama, S Umemoto, Kenichi Takemura, Yasuo Ohishi, Osamu ShimomuraAbstract:X-Ray Powder Diffraction from solid deuterium was first observed under high pressure at SPring-8. At pressures up to 62 GPa and room temperature, three Diffraction lines (100, 002, 101) of the hcp lattice were observed. The derived cell volume and the c/a ratio were consistent with single-crystal data. At 83 K and 94 GPa, three Diffraction lines were also obtained and assigned to the hcp lattice.

X-Ray Powder Diffraction from solid deuterium
Solid State Communications, 2001Co-Authors: Haruki Kawamura, Yuichi Akahama, S Umemoto, Kenichi Takemura, Yasuo Ohishi, Osamu ShimomuraAbstract:X-Ray Powder Diffraction from solid deuterium was observed under high pressure and low temperature at SPring-8. Three Diffraction lines were obtained, and they are assigned to the 100, 002 and 101 lines of the hcp lattice. The center of each deuterium molecule is still on the hcp lattice in phase II.

Determination of enantiomeric excess of leucine and valine by X-Ray Powder Diffraction
European Journal of Chemistry, 2010Co-Authors: Elżbieta Tadeusiak, Rafal Kruszynski, Agata Trzesowska-kruszynska, Tomasz Sieranski, Bartlomiej LewinskiAbstract:Two amino acids, leucine and valine, were studied by X-Ray Powder Diffraction (XRPD). The linear correlations between intensity of racemate (decrease) or enantiomer (increase) and enantiomeric excesses were observed in each case.
