Abstract
Materials in the single-nanometer region (less than 10nm) such as single-nano particles or nanoclusters have attracted attention in recent years. The single-nanometer region refers to the material dimension below about 10 nm. It is known in this region that substantial properties of a material, such as electric, magnetic, optical, thermal, and chemical properties, vary drastically. The authors' research group has synthesized a bulk solid consisting of grains of single-nanometer scale using particles of single-nanometer scale as a raw material and a bulk solid composed of a matrix and a second phase of single-nanometer scale (hereinafter referred to as a single nanocomposite), and studied on the structure and characteristics.
