Journal ArticleDOI
Hydrogen storage in Pd nanocrystals covered with a metal–organic framework
Guangqin Li,Hirokazu Kobayashi,Jared M. Taylor,Ryuichi Ikeda,Yoshiki Kubota,Kenichi Kato,Masaki Takata,Tomokazu Yamamoto,Shoichi Toh,Syo Matsumura,Hiroshi Kitagawa,Hiroshi Kitagawa +11 more
TL;DR: The significantly enhanced hydrogen storage capacity was confirmed by hydrogen pressure-composition isotherms and solid-state deuterium nuclear magnetic resonance measurements, and the speed of hydrogen absorption in the Pd nanocrystals is also enhanced by the MOF coating.
Journal ArticleDOI
Solid Solution Alloy Nanoparticles of Immiscible Pd and Ru Elements Neighboring on Rh: Changeover of the Thermodynamic Behavior for Hydrogen Storage and Enhanced CO-Oxidizing Ability
Kohei Kusada,Hirokazu Kobayashi,Ryuichi Ikeda,Yoshiki Kubota,Masaki Takata,Shoichi Toh,Tomokazu Yamamoto,Syo Matsumura,Naoya Sumi,Katsutoshi Sato,Katsutoshi Sato,Katsutoshi Nagaoka,Hiroshi Kitagawa,Hiroshi Kitagawa +13 more
TL;DR: Pd(x)Ru(1-x) solid solution alloy nanoparticles were successfully synthesized over the whole composition range through a chemical reduction method, although Ru and Pd are immiscible at the atomic level in the bulk state.
Journal ArticleDOI
Fabrication, characterization and Raman study of anatase-TiO2 nanorods by a heating-sol–gel template process
TL;DR: In this article, a new process named heating-sol-gel template process for fabrication oxide nanorods with large quantity, good compositional uniformity and fine crystallinity based on a template method was proposed and the above characterization results support the new process is a desirable process.
Journal ArticleDOI
High-pressure torsion of TiFe intermetallics for activation of hydrogen storage at room temperature with heterogeneous nanostructure
Kaveh Edalati,Kaveh Edalati,Junko Matsuda,Junko Matsuda,Hideaki Iwaoka,Hideaki Iwaoka,Shoichi Toh,Etsuo Akiba,Etsuo Akiba,Zenji Horita,Zenji Horita +10 more
TL;DR: In this article, the authors showed that high pressure torsion (HPT)-processed TiFe exhibits heterogeneous microstructures composed of nanograins, coarse-grains, amorphous-like phases and disordered phases with a high hardness of ∼1050 Hv.
Journal ArticleDOI
Fabrication and characterization of anatase/rutile–TiO2 thin films by magnetron sputtering: a review
Sakae Tanemura,Lei Miao,Wilfried Wunderlich,Masaki Tanemura,Yukimasa Mori,Shoichi Toh,Kenji Kaneko +6 more
TL;DR: In this article, the state-of-the-art results on anatase and/or rutile TiO2 thin films, fabricated by helicon RF magnetron sputtering, with good crystal quality and high density, gave the state of the art knowledge on systematic interrelationship for fabrication conditions, crystal structure, composition, optical properties and bactericidal abilities.
