This volume chronicles the proceedings of the Fourth International Symposium on Contact Angle, Wettability and Adhesion, held June 14-16, 2004 in Philadelphia, PA. It contains 31 peer-reviewed and edited papers, addressing fundamental theory, as well as applications across a wide range of technologies.

From the Preface: “[T]opics covered include: fundamental aspects of contact line region; evaporative behavior of sessile drops; various factors influencing contact angle measurements; different kinds of contact angles; various ways to measure contact angles; contact angle hysteresis; contact angle measurements on various materials (smooth, rough, porous, heterogeneous); effect of electric field on contact angle (electrowetting); wetting and spreading on heterogeneous surfaces; factors influencing wetting/spreading phenomena; determination of solid surface free energy via contact angle measurements; application of AFM in determining solid surface tension at the nano-scale; ultrahydrophobic surfaces; surface modification and wettability; multiphase flow dynamics in porous media; thin film coatings for textile materials; bio-fouling resistant coatings; relationship between wetting and adhesion; and relevance/importance of wetting and surface energetics in technological applications...”

Target Audience: Researchers, technologists, and upper-level students interested in the many ramifications of contact angle and wettability.
