This volume explains the physical phenomena and mechanisms at work in surface and interfacial tensions and gradients, their direct impact on interface shape and dynamics, and their significance to numerous applications. The contributors offer complete coverage of the latest theoretical, experimental, and computer-based data — including modern simulations of complex interfacial motions, such as bubble motion in liquids as well as bubble nucleation and detachment. There are two chapters each on contact angle measurement and foam systems.

From the Preface: “The effects of surface and interfacial tension are seen throughout nature and science in disciplines ranging from medicine to chemical engineering. The specialist contributions presented in this volume draw together current knowledge on a wide range of topics: the measurement of tensions and contact angles, shapes of interfaces, the motion and nucleation of bubbles, the effect of surfactants, the formation and stability of foams, and the wetting of fibers. The emphasis is on physical understanding backed by careful experimentation and theoretical interpretation...”

Target Audience: Physical, surface and colloid chemists; interfacial scientists; chemical engineers; and upper-level students in these disciplines.
