Outline of Final Research Achievements

The purpose of this study is to confirm the ultraprecision polishing action of carbon onion, which is one of nanoparticles with closed shell structure of graphene. Polishing experiments are carried out using workpieces of single crystal SiC and quartz glass. The experiments result in the formation of scratch free surface with roughness smaller than 1 nm in terms of the maximum roughness height. This reveals the ultraprecision polishing action of carbon onion particles and their higher mechanical strength than single crystal SiC. In addition, the possibility of compression fracture test of a single nanoparticle using an atomic force microscope equipped with a nanoindentation unit and a diamond indenter.
