Interfacial energetics principles

It can be derived from Antonow s rule, 15.7.4], applying it to partial wetting but accounting for the adhesion between solid and liquid, assuming it to be dominated by the Van der Waals, or dispersion, parts of the surface tensions, y and y. Various studies have shown that [5.7.5] is quite effective for materials that mainly interact through dispersion forces and that it remains a reasonable approximation for systems in which other interactions also operate. The root in the r.h.s. of [5.7.5] stems from the assumption that Berthelot s principle may be applied. In sec. 2.11b we argued that this principle may be applied only to the energetic part of the interfacial tensions and that a more correct form is... 

There exist innumerable practical situations in which the energetic balance of interfacial regions must be controlled in order to make use of the unique characteristics of a system. The primary purpose of this work is to present in a bare bones way the fundamental natures of various interfaces and illustrate how those characteristics can (in principle) be manipulated to the best advantage of ourselves and our environment.
