Size effects on the Kauzmann temperature and related thermodynamic parameters of Ag nanoparticles

Based on the Sutton - Chen many-body potential function, several thermodynamic parameters of Ag are simulated by molecular dynamics. The parameters simulated are size dependences of the Kauzmann temperature T-K and melting temperature T-m, and size and temperature dependences of melting enthalpy H-m and melting entropy S-m. The simulation results and the results of the thermodynamic theory models of T-K and T-m show good agreement, indicating that as the size of the Ag particles decreases, the T-K and Tm functions decrease. However, the ratio of T-K and T-m of Ag nanoparticles is size-independent.
