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 predicted the size-dependent and dimension-dependent melting temperatures of molecular nanocrystals whose diameters are at the lower bound of the mesoscopic size range, of 2 to 10 nm. In this size range, the depression of the melting temperature is no longer proportional to the reciprocal of the diameter of the nanocrystals. The model predictions are supported by experimental and molecular dynamics simulation results for cyclohexane, benzene, n-decane, methyl chloride, oxygen, neon, argon, and krypton nanocrystals.
