Synthesis of quasicrystals and their structure analysis, and designing catalysts in terms of metallurgy

Quasicrystals(QCs) and alloy catalysts are the main foci of the lab, ranging from fundamental studies to material developments. The QC-related topics include the search for novel quasicrystalline alloys, structure analysis, phase transformation mechanisms, mathematical modeling, the development of QC-reinforced high-strength Mg alloys and QC catalysts. We also pursue a new paradigm for designing catalysts in terms of metallurgy by controlling electronic structure and microstructure: 1) control of electronic structure by alloying to adjust the catalytic function, aiming at replacement for precious metals, 2) tailoring nanoarchtectures through self-organization processes generated by leaching or redox treatments for developing new processes for catalysts.
