Size-Dependent Cohesive Energy and MeltingOf Non-Spherical Nanoparticles

摘要

All most all theoretical models assume spherical nanoparticles. However,thermodynamic properties of non-spherical nanoparticles are the subject of recent interests. Inthis article, we have discussed the size-dependent cohesive energy and melting of non-sphericalnanoparticles based on liquid-drop model. The surface to volume ratio is different for differentshapes of nanoparticles and as a consequence, the variation of cohesive energy and melting ofnon-spherical nanoparticles is different from that of spherical case. By analyzing the reportedexperimental results, it has been observed that liquid-drop model can be used to understand thesize-dependent cohesive energy and melting of non-spherical nanoparticles.
