Systematic Studies on Structural Parameters for Nanotubular Assembly of Hexa-peri-hexabenzocoronenes
Wusong Jin,Yohei Yamamoto,Takanori Fukushima,Noriyuki Ishii,Jungeun Kim,Kenichi Kato,Masaki Takata,Takuzo Aida +7 more
TL;DR: The hierarchical nanotubular structure, rendered by virtue of a synchrotron radiation technique, was virtually identical to the previous proposal, where the nanotubes are composed of helically coiled bilayer tapes with a tilting angle of approximately 45 degrees.
Journal ArticleDOI
Hydrogen absorption in the core/shell interface of Pd/Pt nanoparticles.
TL;DR: The results of the hydrogen pressure−composition (PC) isotherm and solid-state 2H NMR measurements revealed that the Pd/Pt nanoparticles can absorb hydrogen, and most of the absorbed hydrogen atoms are situated around the interfacial region between the PD core and the Pt shell.
Journal ArticleDOI
High pressure synthesis, crystal structure and physical properties of a new Ni(ii) perovskite BiNiO3
Shintaro Ishiwata,Masaki Azuma,Masaki Azuma,Mikio Takano,Eiji Nishibori,Masaki Takata,Makoto Sakata,Kenichi Kato +7 more
TL;DR: A triclinic perovskite, BiNiO3, has been synthesized at a high pressure of 6 GPa in an oxidizing atmosphere as mentioned in this paper, which showed insulating behavior with localized spins of S = 1.
Journal ArticleDOI
MEED: a program package for electron-density-distribution calculation by the maximum-entropy method
TL;DR: MEED (maximum-entropy electron density) is a program package to calculate the electron-density distribution from a set of structure-factor data by the maximum-entropic method and can overcome, to some extent, one of the biggest drawbacks of MEM analysis, the vast computing time required.
Journal ArticleDOI
Phase-Change Materials: Vibrational Softening upon Crystallization and Its Impact on Thermal Properties

TL;DR: In this paper, the thermal properties of the amorphous and crystalline state of phase-change materials are investigated and it is shown that higher thermal displacements and a more pronounced anharmonic behavior in the crystalline phase are related to the change of bonding upon crystallization, which leads to an increase of the sound velocity and a softening of the optical phonon modes at the same time.
