Abstract

We have studied melting temperature, Debye temperature, thermal expansivity and specific heat for some nanomaterials viz. Al, Fe, Co, Cu, Se, Ag, In, Sn, Au and Pb by using the Jiang model and other models reported in recent literature. We have also modified these models by taking into account the dependences of thermophysical properties on the size and shape as well as the change in lattice volume of nanomaterials. The modified formulations have been used to obtain the results for various properties of nanomaterials. The results have been compared with the available experimental data. It is found that the predicted results present good agreement with the experimental studies as well as with theoretical results reported recently. The melting temperature and other thermophysical properties for the nanomaterials under study are improved significantly by taking into account the variation of lattice volume.
