Z. Wen et al., The melting temperature of molecular nanocrystals at the lower bound of the mesoscopic size range, J PHYS-COND, 12(41), 2000, pp. 8819-8824
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.
