Journal ArticleDOI
A new ternary magnesium–titanium hydride Mg7TiHx with hydrogen desorption properties better than both binary magnesium and titanium hydrides
Daisuke Kyoi,Toyoto Sato,Ewa Rönnebro,Naoyuki Kitamura,Atsushi Ueda,Mikio Ito,Shigeru Katsuyama,Shigeta Hara,Dag Noréus,Tetsuo Sakai +9 more
TL;DR: A magnesium-titanium hydride, Mg7TiHx exhibits 5.5 mass% (x≈12.7) and decomposes into Mg and TiH1.9 upon releasing 4.7 mass% of hydrogen around 605 K.
Journal ArticleDOI
Thermoelectric properties of the skutterudite Co1−xFexSb3 system
TL;DR: In this article, the phase equilibrium and thermoelectric properties of Co1−xFexSb3 ternary system up to high iron context x=0.40 were examined.
Journal ArticleDOI
Synthesis of NaxCo2O4 thermoelectric oxides by the polymerized complex method
TL;DR: In this paper, the thermoelectric oxide Na x Co 2 O 4 was synthesized by the polymerized complex method, which provided a flaky powder, and the sintered sample showed a high density, a fine microstructure, and improved the performance compared to a sample prepared by the conventional solid state reaction method.
Journal ArticleDOI
Thermoelectric properties of (Zn1−yMgy)1−xAlxO ceramics prepared by the polymerized complex method
Shigeru Katsuyama,Y. Takagi,Mikio Ito,Kazuhiko Majima,Hiroshi Nagai,H. Sakai,K. Yoshimura,K. Kosuge +7 more
TL;DR: In this paper, the microscopic structure and thermoelectric properties were examined comparing with the experimental results of the samples prepared by the conventional solid-state reaction method, which indicated that the solubility limit of Al in Zn1−xAlxO is about x=0.01, which was also confirmed by 27Al nuclear magnetic resonance spectroscopy.
Journal ArticleDOI
A novel magnesium-vanadium hydride synthesized by a gigapascal-high-pressure technique
Daisuke Kyoi,Toyoto Sato,Ewa Rönnebro,Yasufumi Tsuji,Naoyuki Kitamura,Atsushi Ueda,Mikio Ito,Shigeru Katsuyama,Shigeta Hara,Dag Noréus,Tetsuo Sakai +10 more
TL;DR: Vajeeston and Fjellvag as mentioned in this paper developed interstitial ternary alkaline-earth-transition metal hydrides formed by immiscible metals that are held together by the presence of hydrogen atoms.
