By S. Durand-Vidal

The purpose of this ebook is to supply the reader with a latest presentation of ionic strategies at interfaces, for actual chemists, chemists and theoretically orientated experimentalists during this box. The dialogue is principally at the structural and thermodynamic houses, with regards to shortly on hand statistical mechanical types. a few dynamic homes also are offered, at a extra phenomenological point. The preliminary chapters are dedicated to the presentation of a few uncomplicated innovations for bulk houses: hydrodynamic interactions, electrostatics, van der Waals forces and thermodynamics of ionic options within the framework of a specific version: the suggest round approximation (MSA). particular positive aspects of interfaces are then mentioned: experimental thoughts akin to in-situ X-ray diffraction, STM and AFM microscopy are defined. Ions at liquid/air, liquid/metal and liquid/liquid interfaces are thought of from the experimental and theoretical perspective. finally a few dynamic (transport) houses are integrated, specifically the self-diffusion and conductance of small colloids (polyelectrolytes and micelles) and the kinetics of solute move at loose liquid/liquid interfaces.

This page intentionally left blank. 1 Introduction Microscopic observations of colloidal particles in the nineteenth century have shown their tendency to form persistent aggregates, even for uncharged particles without specific reactive site. This behaviour indicates attractive interparticle force. This attraction arises from dipolar interaction: local fluctuations in the polarization within one particle induces correlated response in the others via the propagation of electromagnetic waves.
