Abstract

Melting point depression and enhancement of nanomaterials have been found to depend on size, dimension and surface properties of the nanomaterials. Ours is a phenomenological model based on classical considerations regarding melting of nanomaterials. The model extensively discusses a nanorod, a bare nanorod and an encapsulated nanorod separately. We have considered a nanorod and using a simple minded approach of cohesive binding energy observed that the melting point of the nanorod gets depressed as the size goes down. Further, to illustrate the phenomena, we have adopted a classical thermodynamic approach which is mainly based on Gibbs energy of a bare and encapsulated (containing matrix) nanorod. We have minimized the Gibbs energy for the two nanosystems separately in different phases and calculated and analyzed the results for the melting point of the nanorod. The results of our models are consistent with both of experimental results and other thermodynamic models. Keywords : Nanomaterials, Encapsulated Nanorod, Thermodynamic
