Chemistry and electronics of oxides from carbon dioxide to perovskite

Oxides are thermodynamic stable form of materials in terrestrial conditions to exist as final products of energy consumption proceeding in nature as well as in civilization. The accumulation of heat capacitive CO, in atmosphere is becoming a serious environmental problem. Solid oxides as minerals in the earth shell had been used mainly for heat resistant structural materials as well as for raw materials of metals, but recent advanced chemistry and physics have been manifesting new electronic and chemical potentials bidden in oxides. Current interest and studies on oxides are directed towards two main areas: (1) prevention Of CO2 increase in atmosphere by its fixation and/or by saving the consumption of fossil fuels and (2) discovery and utilization of superfunctionality in oxides. Triggered by Bednorz and Muller's discovery of high Tc superconductor, the latter topics have been attracting rapidly growing interest from viewpoints of both fundamental research and practical application. In commemoration of WOE homecoming to the place of inauguration, a founder of WOE appreciates much to the program committee for providing him with this opportunity of briefing the workshop motivation and of reviewing his research career on oxide materials.
