• solid-liquid interfacial energy
• size dependence
• temperature dependence

Based on the previous models for bulk and size-dependent solid-liquid interfacial energy y(s10) and y(sl)(r) with the additional temperature-dependent melting enthalpy Delta H-m(T) and improved Gibbs free energy difference functions g(m)(T) between crystal and liquid, y(sl)(r,T) function is quantitatively modeled. It is found that the gamma(CNT) values of Turnbull's undercooling experiments correspond to the model predictions for the nucleus-liquid interfacial energy rather than y(s10). This correspondence leads to the reexaminations on the classic nucleation theory. Moreover, the linear relationship between gamma(sl)(r,T) and Delta H-m/V is found to be always valid at any degree of undercooling where V is the molar volume. Finally, the size range of gamma(sl)(r,T) for elements is also discussed.
