Why Do Nanomaterials Have Different Melting Points?
The melting points of nanomaterials are generally lower than those of bulk materials. This is because a larger proportion of atoms are located on the surface of nanomaterials, where they experience fewer cohesive forces compared to atoms within the bulk. Consequently, less energy is needed to disrupt the atomic structure, leading to a lower melting point. The curvature of nanoparticles also contributes to this effect by creating additional strain on the atomic bonds.
