Line tension effects

Note that, in general a 5 ao (see Figure 4.16). Besides, both ao and a can depend on the radius of the contact line due to line tension effects. In the case of straight contact line from Equations 4.147 and 4.154, we derive [252]... 

Thus far we derived analytical expressions for the nucleation work and for the size of the critical nucleus neglecting the line tension effect. The latter can be taken into consideration if the general equation (1.32) is combined... 

Volmer and Weber [2.14], Farkas [2.15] and Kaischew and Stranski [2.16-2.18] were the first who examined the stationary nucleation kinetics and derived theoretical expressions for the stationary nucleation rate. However, in this Chapter we shall present the results of the more rigorous treatments of Becker and Doring [2.6] and ofZeldovich [2.19] and Frenkel [2.20] who laid the foundations of the contemporary classical nucleation theory (see also [2.V-2.9] and [2.21-2.24]). For the sake of simplicity we shall neglect both the line tension effects (equations (1.42) and (1.70)) and the dependence of the specific free surface energy on the size of the clusters (equation (1.43).
