Toshiyuki Nohira教授の研究室では、塩化物イオンを含む融けた塩系を用いた電気化学的プロセスを通じて希土類金属と遷移金属の合金を制御的に合成する研究を行っています。特に、プラセオジュム・ニッケル系合金の急速な電気析出挙動や、その結晶構造・拡散挙動の解明が主なテーマです。TEMや回折法を用いた微視的解析により、合金形成のメカニズムを明らかにし、次世代のエネルギー材料開発に貢献することを目的としています。

The electrochemical formation of Pr-Ni alloys was investigated in a molten system at . A coherent and dense film was rapidly formed on a Ni electrode by potentiostatic electrolysis at . When a thin Ni electrode was used, PrNi was formed at after the whole electrode became . The formed electrodes were transformed to other phases, i.e., , , , and Ni, by electrochemical displantation. The formation reactions of the alloys and the corresponding equilibrium potentials were clarified. From morphologic
