A wide variety of two- and three-dimensional physical-chemical systems display domain patterns in equilibrium. The phenomenology of these patterns, and of the shapes of their constituent domains, isâ€¦ (More)

The behavior of electrolyte solutions close to a charged surface is studied theoretically. A modified Poissonâ€“Boltzmann equation that takes into account the volume excluded by the ions in addition toâ€¦ (More)

The adsorption of large ions from solution to a charged surface is investigated theoretica A generalized Poisson-Boltzmann equation which takes into account the finite size of the ion presented. Weâ€¦ (More)

We present a theory for the kinetics of surfactant adsorption at the interface between an aqueous solution and another fluid (air, oil) phase. The model relies on a free-energy formulation. Itâ€¦ (More)

Curvature-induced instabilities in membranes and amphiphilic films are investigated by introducing a general coupling between a shape variable (such as curvature) and Â«internalÂ» degrees of freedomâ€¦ (More)

We present an extension to the Poisson-Boltzmann model where the dipolar features of solvent molecules are taken explicitly into account. The formulation is derived at mean-field level and can beâ€¦ (More)

We predict the nature (attractive or repulsive) and range (exponentially screened or long-range power law) of the electrostatic interactions of oppositely charged, planar plates as a function of theâ€¦ (More)

We study the electric double layer by combining the effects of ion finite size and dielectric decrement. At high surface potential, both mechanisms can cause saturation of the counter-ionâ€¦ (More)

The adsorption kinetics of the cationic surfactant dodecyltrimethylammonium bromide at the air-water interface has been studied by the maximum bubble pressure method at concentrations below theâ€¦ (More)
