Theoretically, a plot of ln(Cmax/Tmax) versus 1/Tnuc should be linear with a negative slope whose value will be equal to G/R with an intercept equal to ln(kn). Once the nucleation kinetic constant, kn and the G is determined, then mathematically it is possible to estimate at the nucleation rate J using equation ( ) at a fixed cooling rate R' and the MSZW measured at different 𝑇 * (and the corresponding Tnuc). Furthermore, from the classical nucleation theory, it is also possible to calculate the surface energy, or the interfacial tension associated with the formation of stable nucleus using the expression: 9
