Bubble and Drop Interfaces Progress in Colloid and Interface Science Series

This book describes the most important experimental methods for characterizing liquid interfaces, such as drop profile analysis, bubble pressure and drop volume tensiometry, capillary pressure technique, and oscillating drops and bubbles. It presents practical experimental details as well as the underlying theoretical bases. In addition, the book covers a number of applications based on drops and bubbles, such as rising bubbles and the complex process of flotation. It also offers a discussion on wetting, characterized by the dynamics of advancing contact angles.
