TLDR
In this paper, the melting temperature of free standing nanosolids decreases with decrease in the solid size, and for spherical nanoparticles, nanowire and nanofilm of a material in the same size is 3:2:1.Abstract:
By considering the surface effects, the melting temperature of nanosolids (nanoparticles, nanowires and nanofilms) has been predicted based on size-dependent cohesive energy. It is shown that the melting temperature of free standing nanosolids decreases with decrease in the solid size, and the melting temperature variation for spherical nanoparticle, nanowire and nanofilm of a material in the same size is 3:2:1. The present theoretical results on Sn and Pb nanoparticles, In nanowires and nanofilms are consistent with the previous experimental values.read more

Size-Dependent Materials Properties Toward a Universal Equation
TL;DR: A universal equation is developed here which is particularly helpful when experiments are difficult to lead on a specific material property and only requires the knowledge of the surface area to volume ratio of the nanomaterial, its size as well as the statistic followed by the particles involved in the considered material property.
