ABSTRACT

Line tension was introduced in Chapter 1 as part of the generalized theory of capillarity. Line tension is the work of formation (or excess energy) of a unit length of line phase, much as surface tension is the work of formation of a unit area of surface phase. The line phase considered is usually a three-phase line such as the circular
