This book explains and summarizes the fundamentals of soft interfaces and soft particles from a colloid and surface chemistry standpoint, bringing knowledge together into a single resource for the first time. It provides detailed mathematical description of colloidal and interfacial systems, with a particular emphasis on ionic, electrokinetic, and electrostatic phenomena. Hiroyuki Ohshima covers the most recent theoretical advances in the field of electrostatic interactions between soft interfaces, electrophoresis, diffusiophoresis, gel electrophoresis of soft particles including ionic size effects, ion-partitioning effects, and the effects of hydrodynamic slip on hydrophobic surfaces. It will help readers by providing a range of approximate analytic formulas which can be used to interpret various interfacial phenomena of soft interfaces and analyze experimental data in various fields. Fundamentals of Soft Interfaces in Colloid and Surface Chemistry is written for graduate students and researchers chiefly in chemistry but also chemical engineering, physics, and materials science.
