■要約
Mechanochemical phenomena are generally induced during ball milling for producing fine powders. Not only size reduction and shape change of the particles but also disorder and/or transformation of the crystal of solid materials are often observed during ball grinding. The latter is called mechanochemical phenomena, and disordered solid materials have a high potential to react with gas, liquid and other solid materials. These phenomena could synthesize functional powder materials, decompose ground materials at low temperature and generate useful gases from the milled sample in subsequent heating operation. The research in this group is categorized into four subjects: The first is the development of new mechanical refining processes and recycling of valuable materials from wastes, the second is synthesis of functional powder materials with an aid of mechanochemical effects and reactions, the third is production of hydrogen from biomass and plastic wastes, and the fourth is development of DEM (Discrete Element Method) simulation method for the prediction of grinding and mechanochemical reaction and their optimizations in milling/mechanochemical operations.
