Notable hydriding properties of a nanostructured composite material of the Mg2Ni-H system synthesized by reactive mechanical grinding
TL;DR: In this article, the intermetallic compound Mg2Ni was mechanically ground under a hydrogen atmosphere to synthesize a nanostructured composite material that is composed of nanocrystalline intra-grain and disordered inter-grain regions.
Journal ArticleDOI
Diffusion Tensor Magnetic Resonance Imaging of Disruption of Regional White Matter in Schizophrenia
Tomohisa Minami,Kenji Nobuhara,Gaku Okugawa,Katsunori Takase,Tsunetaka Yoshida,Satoshi Sawada,Sangkil Ha-Kawa,Kazutaka Ikeda,Toshihiko Kinoshita +8 more
TL;DR: Findings support the view that the pathological process is a distortion of the central nervous system myelination affecting the whole white matter in schizophrenia.
Journal ArticleDOI
Structural and hydriding properties of the MgNiH system with nano- and/or amorphous structures
Shin Ichi Orimo,Kazutaka Ikeda,Hironobu Fujii,Yoshinori Fujikawa,Yasuyuki Kitano,K. Yamamoto +5 more
TL;DR: In this paper, the properties of the alloys Mg-x at.%Ni (x = 33, 38, 43 and 50) with different nanometer-scale structures were successively synthesized by mechanical grinding of Mg2Ni mixed with various amounts of additional Ni, and the relations between their structural and hydriding properties were investigated in detail.
Journal ArticleDOI
Distribution of prepro-nociceptin/orphanin fq mrna and its receptor mrna in developing and adult mouse central nervous systems
TL;DR: The distinct cellular expression pattern of the N/OFQ system suggests that the release of N/ OFQ from interneurons may lower neuronal and synaptic activities of neighboring neurons, leading to integration or modulation of local circuits.

TL;DR: The superconductivity in iron pnictide compounds occurs near a magnetic phase and magnetic spin fluctuations are prime candidates for the superconducting pairing mechanism as mentioned in this paper, and it has been shown that a second magnetic phase, next to another super-conducting phase, is found at higher doping levels.
