This paper reviews the main structural characteristics and excellent physical properties of nanocrystalline materials and C60
some studies by positron annihilation on interfacial structure
therrnal stability and pressure effect of nanocrystalline materials and the positron lifetimes of C60.The significance of these studies and some questions are also pointed out.
