ABSTRACT

At the minimum for R=Req, the pressure inside the droplet Pi becomes exactly equal to the reference pressure Pr, which, for Winsor I and Winsor II cases, is equal to Pe, thus establishing equality between the chemical potentials for the core component in the droplet and in the excess phase. For R>Req, the internal pressure is higher than in the excess phase and, consequently, the chemical potential is higher, resulting in a tendency for the
