A monograph examining recent progress in the field of inhomogeneous fluids, focusing on the theoretical - as well as experimental - techniques used. It presents the comprehensive theory of first-order phase transitions, including melting, and contains numerous figures, tables and display equations., The contributors treat such subjects as: exact sum rules for inhomogenous fluids, explaining density functional and integral equation methods, exact solutions for two-dimensional homogeneous and inhomogeneous plasmas, current advances in the theory of interfacial electrochemistry, wetting experiments and the theory of wetting, freezing, with an emphasis on quantum systems and homogeneous nucleation in liquid-vapour and solid-liquid transitions, self-organizing liquids as well as kinetic phenomena in inhomogeneous fluids, using a modified Enskog theory., Featuring over 1000 bibliographic citations, this volume is aimed at physical, surface, colloid and surfactant chemists, also physicists, electrochemists and graduate-level students in these disciplines.
