nanometer-size particles is quite a different process from that of bulk materials see, e.g., Refs. 5–8 . As the size of a particle decreases, the surface-to-volume ratio is increased inversely proportional to the radius of the particle. As a re-sult, the surface atoms become more prone to detach from their positions and diffuse on the surface.
