Research Clusters

Nano-Organics and Nano-Hybrids

Our research cluster at the IROAST focuses on functional nano-objects composed of organics, inorganics and hybrids, which include self-assemblies, nano-particles, nano-catalyst, graphene oxide, quantum dots, and inorganic/organic hybrids. Currently 8 members including 4 visiting professors of IROAST from France, Spain, United States and China join the research unit. The international collaborative projects regarding basic and advanced chemistry on nano-organics and nano-hybrids are initiated and carried out by each member, and their targets are widely distributed across highly diverse fields.
