摘要：

The present study is an theoretical attempt to predict the variation of melting temperature of some nanoparticles with shape and size from simple theoretical model. The theoretical model is based on cohesive energy of nanoparticles in compression with the bulk materials. Here we have considered Sn, Au, Ag, Al, Ni and Pb nanoparticles for the study of shape and size dependence behaviour of melting temperature. The overall study found that the melting temperature of nanomaterials is depend on shape and size and the value of melting temperature increases with increase in size of nano solids. Further, It has been observed that nano film shape have highest melting point and regular tetrahedron shape has lowest melting point among all the considered shape.
