The melting temperature of molecular nanocrystals at the lower bound of the mesoscopic size range

Our simple thermodynamic model. free of any adjustable parameters, has pred icted the size-dependent and dimension-dependent melting temperatures of mo lecular nanocrystals whose diameters are at the lower bound of the mesoscop ic size range, of 2 to 10 nm. In this size range, the depression of the mel ting temperature is no longer proportional to the reciprocal of the diamete r of the nanocrystals. The model predictions are supported by experimental and molecular dynamics simulation results for cyclohexane, benzene, il-deca ne, methyl chloride, oxygen, neon, argon, and krypton nanocrystals.
