Thin liquid films are considered to be the basic structural elements of foam and emulsion systems. Consequently, the structure and stability of macro-dispersions are highly dependent on the dynamic structure formation and stability of a single, thin, curved film between unequal-sized bubbles and dro

Drainage of a mobile, symmetric, plane parallel thin liquid film between two gas bubbles is studied. An analytical solution for the rate of thinning of such a liquid film with an insoluble surfactant and having both film elasticity and surface viscosity is presented for the first time.

We report an experimental investigation of the permeability to gas of systems of one or several soap films freely standing in a straight tube, using either reactive gas (NH(3)) or inert gas (argon). The series of soap films appears to be the simplest paradigm of successive lamellae arrangements enco
