Adsorption of Large Ions from an Electrolyte Solution: A Modified Poisson-Boltzmann Equation
I. Borukhov, D. Andelman, H. Orland
The behavior of electrolyte solutions close to a charged surface is studied theoretically. A modified Poisson-Boltzmann equation which takes into account the volume excluded by the…
Self-Assembly in Mixtures of Polymers and Small Associating Molecules
H. Diamant, D. Andelman
The interaction between a flexible polymer in good solvent and smaller associating solute molecules such as amphiphiles (surfactants) is considered theoretically. Attractive correl…
The Influence of Substrate Structure on Membrane Adhesion
P. S. Swain, David Andelman
We consider a membrane both weakly and strongly adhering to a geometrically structured substrate. The interaction potential is assumed to be local, via the Deryagin approximation,…
Kinetics of Surfactant Adsorption at Fluid-Fluid Interfaces: Surfactant Mixtures
G. Ariel, H. Diamant, D. Andelman
The adsorption at the interface between an aqueous solution of several surface-active agents and another fluid (air or oil) phase is addressed theoretically. We derive the kinetic…
Onset of Self-Assembly in Polymer-Surfactant Systems
Haim Diamant, David Andelman
The onset of self-assembly in a dilute aqueous solution containing a flexible polymer and surfactant is theoretically studied. Focusing on the effect of the surfactant on polymer c…
