Book Description

Contains selected invited papers presented at the 10th International Symposium on Surfactants in Solution held in Caracas, Venezuela. The volume covers phase behaviour of monolayers, contact angle hysteresis, micellar relaxation, micellar catalyzed reactions, polymerization in microemulsions, polymer-surfactant complexation, asphaltenes, and more.

Table of Contents

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.
