摘要：

In the present work, a concise overview of the key aspects related to the thermal conductivity of metallic nanoparticles has been studied with the variation of size and shape using bond-energy model of cohesive energy for low dimension materials. In the present work, ZrO 2 , Cu, Ni, In, Pb and Sn nanoparticles have been considered to calculate the effective thermal conductivity of metallic nanoparticles. Usually, the thermal conductivity decreases by lowering the size of nanoparticle, below 30 nm, it decreases sharply. It has also observed that the computed values have a maximum deviation +/- 7 % with experimental results.
