Nonlinear spontaneous oscillations at the liquid/liquid interface produced by surfactant dissolution in the bulk phase
Article Abstract:
The result of theoretical and experimental studies of spontaneous nonlinear oscillations produced at the liquid/liquid interface by surfactant transfer from a point source situated in one of the bulk phases are presented. It is concluded that auto-oscillations at the air/liquid and liquid/liquid interfaces are governed by very similar mechanism but their characteristics are strongly dependent on the properties of the two contacting media, in particular, on the surfactant partition coefficient.

Thermodynamics of aqueous poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide)/surfactant mixtures. Effect of the copolymer molecular weight and the surfactant alkyl chain length
Article Abstract:
The effect of the hydrophobicity of the surfactant, the copolymer molecular weight, at constant hydrophobic/hydrophilic ratio, and the hydrophilicity of the copolymer on the interactions between EOaPObEOa and sodium alkanoates is investigated by calorimetry at 298 K. It concluded that L64 has a larger hydrophobic character than F68 and the copolymer molecular weight plays a small role.

Surfactant transfer through a liquid membrane: Origin of spontaneous oscillations at the membrane/acceptor phase interface
Article Abstract:
Instability due to surfactant redistribution in a liquid membrane system consisting of two solutions separated by a layer of immiscible liquid was theoretically studied. A mechanism of oscillation, which develops at the membrane/acceptor phase interface, was proposed on the basis of direct numerical simulation of the system evolution.
