Cuprins

Surfactant fundamentals: branched versus linear hydrocarbon chains in surfactants; ellipsometric evidence of anomalous refractive indices; is contact angle hysteresis due to a film present behind a drop? STM molecular imaging of disordered molecular wires; studies of morphology and phase behaviour of monolayers; thermodynamics of adsorption of a cationic surfactant at solid-water interfaces. Micelles and microemulsions: pressure-jump studies on micellar relaxation time and its effect on various technological processes; micellar catalyzed reactions in mixed solvent systems; silica gels from microemulsions; the state of water and surfactant in surfactant-based lyotropic liquid crystals; polymerization of menthyl methacrylate and styrene in ternary emulsions and microemulsions. Polymer-surfactant interactions: polymer-surfactant interactions: effect of ionic strength, polymer charge and binding density on surfactant/polymer aggregates; polymer-surfactant complexation in dilute aqueous solutions. Adsorption of surfactants: adsorption on high and low molecular weight natural surfactants at the crude oil-water interface and their influence on y-pH and y-time behaviour; studies on asphaltenes and related petroleum fractions at interface; influence of surfactants on the adhesion of clay particles to metal surfaces; guidelines for the formulation, composition, and stirring to attained desired emulsion properties (type, droplet, size, viscosity, and stability); double emulsions stabilized by macromelecular surfactants. Biological applications of surfactants: interactions between the dispersed globules of W/O/W emulsions in the presence of proteins and saccharides; the design and evaluation of a novel submicron amphotericin B emulsion in systemic murine cryptococcosis; plant protein purification using cloud point extraction (CPE). Environmental aspects: environmental risk assessment of ethoxylated nonionic surfactants; toxic spill remediation of chlorinated hydrocarbons via microemulsion formation.
