2 0 M ay 2 00 4 Geometric view of the thermodynamics of adsorption at a lineof three-phase contact

We consider three fluid phases meeting at a line of common contact and study the linear excesses per unit length of the contact line (the linear adsorptions Λ i) of the fluid's components. In any plane perpendicular to the contact line, the locus of choices for the otherwise arbitrary location of that line that makes one of the linear adsorptions, say Λ 2… CONTINUE READING
