A thermodynamical model for the shape and size effect on melting of nanoparticls

Abstract

The study of the variation of the properties of materials with the geometrical feature size has a long history because of its importance in many fields The interest has been heightened recently at the nanoscale because nanostructures are pervasive in nature and in modern industry in physics and chemistry the effect of particle size on melting has been discussed since 1900s and this effect is not restricted to any particular material rather it is observed in a variety of materials from metal and alloys and the typical size ranges over 5 10 nm where the melting temperature undergoes a large change newline
