Journal ArticleDOI
Columnar liquid crystal with a spontaneous polarization along the columnar axis.
Daigo Miyajima,Fumito Araoka,Hideo Takezoe,Jungeun Kim,Kenichi Kato,Masaki Takata,Takuzo Aida +6 more
TL;DR: A fan-shaped molecule, carrying hydrogen-bonding amide groups in proximity to its polar aromatic core, self-assembles into a columnar liquid crystalline mesophase, which unprecedentedly possesses a spontaneous macroscopic polarization along the columnar axis.
Journal ArticleDOI
Orbital structures in spinel vanadates A V 2 O 4 ( A = Fe, Mn)
Yoichi Nii,Yoichi Nii,Hajime Sagayama,Taka-hisa Arima,Taka-hisa Arima,Shinobu Aoyagi,Riu Sakai,S. Maki,Eiji Nishibori,Hiroshi Sawa,Kunihisa Sugimoto,Hiroyuki Ohsumi,Masaki Takata +12 more
Journal ArticleDOI
Maximum-entropy-method analysis of neutron diffraction data
TL;DR: In this paper, three approaches to the maximum-entropy analysis of neutron powder diffraction data are examined, and it is concluded that the MEM applied to the rutile data is superior to conventional Fourier transformation and, in spite of the longer computation time, is very well worthwhile.
Journal ArticleDOI
Structural Transition Induced by Charge-Transfer in RbMn(Fe(CN)6) —Investigation by Synchrotron-Radiation X-ray Powder Analysis—
Yutaka Moritomo,Yutaka Moritomo,Kenichi Kato,Akira Kuriki,Masaki Takata,Makoto Sakata,Hiroko Tokoro,Shin-ichi Ohkoshi,Kazuhito Hashimoto +8 more
TL;DR: In this article, a structural transition from the cubic (F\(\overline{4}\)3m; Z = 4) to the tetragonal (I\(overline {4}µm2, Z = 2) phase was observed.
Journal ArticleDOI
Nanosize-Induced Drastic Drop in Equilibrium Hydrogen Pressure for Hydride Formation and Structural Stabilization in Pd–Rh Solid-Solution Alloys
Hirokazu Kobayashi,Hirokazu Kobayashi,Hitoshi Morita,Miho Yamauchi,Ryuichi Ikeda,Ryuichi Ikeda,Hiroshi Kitagawa,Hiroshi Kitagawa,Yoshiki Kubota,Kenichi Kato,Masaki Takata,Shoichi Toh,Syo Matsumura +12 more
TL;DR: The solid-solution state is still maintained in the nanoparticles even after hydrogen absorption/desorption, in contrast to the metastable bulks which are separated into Pd and Rh during the process.
