This volume chronicles the proceedings of the 4th International Symposium on Contact Angle, Wettability and Adhesion held in Philadelphia, PA, June 2004. The world of wettability is very wide and it plays a crucial role in many and varied technological areas ranging from microfluidics to biomedical to agriculture to welding. This volume contains a total of 31 papers covering many ramifications of contact angle, wettability and adhesion. All manuscripts were rigorously peer-reviewed and revised, and properly edited before inclusion in this book. The topics 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; ultralyophobic surfaces; surface modification and wettability; multiphase flow dynamics in porous media; thin film coatings for textile materials; bio-fouling resistant coatings; relationships between wetting and adhesion; and relevance/importance of wetting and surface energetics in technological applications, including cleaning of flooring materials, kinetics of oil removal from coating materials, cell adhesion, and mold compound- metal adhesion in semiconductor packaging.

This book chronicles the proceedings of the Symposium on Contact Angle, Wettability and Adhesion held in honor of Professor Robert J. Good at the American Chemical Society meeting in San Francisco, 6--10 April 1992. The book opens with a description of the professional and personal life of Professor Good, followed by 62 papers divided into four parts. The topics covered include: Contact angle, wettability and adhesion: a critical review (by Professor Good himself); capillary rise of a liquid on a solid (by Professor de Gennes, 1991 Physics Nobel Laureate); various factors influencing contact angle measurements; surface roughness effects in wetting phenomena; microscopic studies of static and dynamic contact angles; contact angles on plates and thin fibers; wettability behavior and surface characterization of various materials; wettability of pharmaceutical powders; wettability of wood; wetting properties of monolayers; control of wettability of polymers using organic surface chemistry; polymer surface modification and wettability; relevance of wettability in adhesion; wettability and bioadhesion; role of water wettability, water transport and adhesion in vision; wettability and adhesion in metal-ceramic systems; relevance of wetting in the control of dust during coal mining.

The topic of wettability (measured in terms of contact angle) is of tremendous interest from both fundamental and applied points of view, Wettability plays an essential role in many industrial processes, so an understanding of factors dictating wettability and how to modulate it is of paramount importance. In the last years there has been an explosive interest in superhydrophobic surfaces (i.e., surfaces with water contact angle of 150° or higher) because of their relevance/importance in many areas ranging from self-cleaning windows to nanofluidics. Also recently there has been heightened activity in the field of electrowetting. Contact Angle, Wettability and Adhesion, Volume 6 is divided into four parts: Part 1: Fundamental Aspects; Part 2: Wettability Control/Modification; Part 3: Superhydrophobic Surfaces; and Part 4: Surface Free Energy and Relevance of Wettability in Adhesion. The topics covered include: a guide to the equilibrium contact angles maze: fundamental aspects of wetting of rough and chemically heterogeneous surfaces: work of adhesion for rock-oil-brine systems; Is the world basic?; wettability control/modification using various approaches; superhydrophobic surfaces and ways to impart superhydrophobicity; adsorption on superhydrophobic surfaces; solid surface energy determination; surface modification of different materials; relevance of wettability and adhesion aspects in a variety of reinforced composites. In essence, this volume reflects the cumulative wisdom of many active and renowned researchers and provides a commentary on contemporary research in the fascinating world of contact angles and wettability. This volume and its predecessors (5 volumes), containing bountiful information, will be of much value to anyone interested/involved in controlling wetting phenomena and their applications.

This is the fourth volume in the series "Advances in Contact Angle, Wettability and Adhesion" initiated to consolidate information and provide commentary on certain recent research aspects dealing with this important topic. Its predecessor Volumes 1, 2 and 3 were published in 2013, 2015 and 2018 respectively. This new book comprising 14 research and review articles is divided into four parts: Part 1: Contact Angle and Wettability Aspects; Part 2: Surface Free Energy and Surface Tension Determination; Part 3: Applied Aspects. The topics covered include: Contact Angle Determination of Talc Powders from Heat of Immersion Surface Wetting at Macro and Nanoscale Wettability of Wood Surfaces with Waterborne Acrylic Lacquer Stains Modulated by DBD Plasma Treatment in Air at Atmospheric Pressure Wettability of Ultrafiltration Membranes Determination of the Surface Free Energy of Solid Surfaces: Can the Best Model be Found Surface Free Energy Characterization of Talc Powders Determination of the Surface Free Energy of Skin and the Factors Affecting it by the Contact Angle Method Determination of Surface Tension Components of Aqueous Solutions using Fomblin HC/25 R Perfluoropolyether Liquid Film as a Solid Substrate Enhancing the Wettability of Polybenzimidazole (PBI) to Improve Fuel Cell Performance Evaluation of Sebum Resistance for Long-Wear Face Make-Up Products Using Contact Angle Measurements Contact Angle Hysteresis of Pressure-Sensitive Adhesives due to Adhesion Tension Relaxation The Potential of Surface Nano-Engineering and Superhydrophobic Surfaces in Drag Reduction Laser Surface Engineering of Polymeric Materials for Enhanced Mesenchymal Stem Cell Adhesion and Growth Sisal-Green Resin Interfaces in Green Composites.

This book describes wetting fundamentals and reviews the standard protocol for contact angle measurements. The authors include a brief overview of applications of contact angle measurements in surface science and engineering. They also discuss recent advances and research trends in wetting fundamentals and include measurement techniques and data interpretation of contract angles.
