Modeling thermodynamic properties of Ni, Sn, Al and Cu nanosolids

Surface atoms and dangling bonds on the surface affect thermodynamic properties. A thermodynamical model, based cohesive energy is presented to discuss melting properties of materials at nanoscale. The model used realize effect size shape temperature Tmn, entropy Smn enthalpy Hmn Ni, Sn, Al Cu metallic nanoparticles. variation in are examined for nanowire, film, spherical, regular tetrahedral, hexahedral octahedral shaped It reported that decrease with decreasing nanoparticles smaller particle size, greater effects when less than 10 nm, it has been predicted reduce appreciably. Also, same more departs from sphere, its changes nanowire tetrahedral shape. Our theoretical results compared available experimental or simulation data. Results by our good agreement observations.
