Surface Forces

This monograph is devoted to long-range surface forces sig nificant far beyond a single monolayer and felt over tens or even hundreds of molecular layers adjacent to an interface. The transi tion from the concept of short-range effects that reigned earlier to the concept of long-range forces simultaneously signified the transition from a two-dimensional world to a three-dimensional one, incomparably richer in physicochemical phenomena. This transition took many years and evolved through many steps. It began with the Gouy-Chapman theory of diffuse ionic atmospheres, which together with London's theory of molecular forces was used as a basis for the development (beginning in 1937) of the DLVO theory of stability of lyophobic colloids. Further elaboration of the theory involved the introduction of new types of force, and a generalization (in 1954) to the case of interaction between unlike particles (hetero coagulation). This theory is fundamental in such large-scale prac tical problems as flotation, water treatment, dyeing, soil science, microbiology, and interaction between biological cells. This book is the first comprehensive monograph devoted to sur face forces. This fact makes it easier to attract the reader's interest; yet, the reader's demands become all the more difficult to satisfy completely. Indeed, the research that we review and analyze here covers about 50 years of work. Much data has been amassed, so that the main problem was a careful selection and an alysis.

Intermolecular and Surface Forces describes the role of various intermolecular and interparticle forces in determining the properties of simple systems such as gases, liquids and solids, with a special focus on more complex colloidal, polymeric and biological systems. The book provides a thorough foundation in theories and concepts of intermolecular forces, allowing researchers and students to recognize which forces are important in any particular system, as well as how to control these forces. This third edition is expanded into three sections and contains five new chapters over the previous edition. Starts from the basics and builds up to more complex systems Covers all aspects of intermolecular and interparticle forces both at the fundamental and applied levels Multidisciplinary approach: bringing together and unifying phenomena from different fields This new edition has an expanded Part III and new chapters on non-equilibrium (dynamic) interactions, and tribology (friction forces)

A general introduction to surface and interfacial forces, perfectly combining theoretical concepts, experimental techniques and practical applications. In this completely updated edition all the chapters have been thoroughly revised and extended to cover new developments and approaches with around 15% new content. A large part of the book is devoted to surface forces between solid surfaces in liquid media, and while a basic knowledge of colloid and interface science is helpful, it is not essential since all important concepts are explained and the theoretical concepts can be understood with an intermediate knowledge of mathematics. A number of exercises with solutions and the end-of-chapter summaries of the most important equations, facts and phenomena serve as additional tools to strengthen the acquired knowledge and allow for self-study. The result is a readily accessible text that helps to foster an understanding of the intricacies of this highly relevant topic.

This book describes intermolecular and interparticle forces in determining the properties of systems such as gases, liquids and solids and of colloidal, polymeric and biological systems. The text includes developments on surface-force measurements, solvation and structural forces, hydration and hydrophobic forces, and ion-correlation forces.

This text is intended for the study of fluid mechanics at an intermediate level. However, the presentation starts with basic ideas in order to form a sound conceptual structure that can support engineering applications and encourage further learning. Subjects treated include hydrostatics, viscous flow, similitude and order of magnitude, creeping flow, potential flow, boundary layer flow, turbulent flow, compressible flow, and non-Newtonian fluids.

Surface and colloid chemistry principles impact many aspects of our daily lives, ranging from the cleaners and cosmetics we use to combustion engines and cement. Exploring the range of this field of study, Surface and Colloid Chemistry provides a detailed analysis of its principles and applications and demonstrates how they relate to natural phenom

This book is derived from the proceedings of the International Workshop on Nanomechanics held at Asilomar Conference Grounds in Pacific Grove, California on July 14-17, 2004. Approximately 70 leading experts from academia, government and industrial sectors in semiconductors, computers, communication, information technology, defense, energy, transportation and aerospace attended the Workshop (see the workshop photo taken on July 16, 2004). The main objective was to convene leading researchers in the nanotechnology community to assess the current state-of-the-art and disseminate recent progress, critical issues, barriers to applications, and directions for future research in nanomechanics. Miniaturization of structural components and functional devices such as electronic, optical, mechanical and electric-magnetic parts has been a recent trend, and the pace has accelerated over the past few years. Advances in micromanufacturing, semiconductor processing (e.g., etching, lithography, grafting, etc.), sensors, actuators and microprocessors have opened up a revolutionary path to the development of new technologies such as micro-electro-mechanical systems (MEMS), nano-electro-mechanical systems (NEMS), micro-engines, smart structures, smart controllers, lab-- a-chip devices, and even bio-medical sensing devices which can detect, analyze, decide and activate appropriate functions in real time. The above-mentioned devices, structures, or systems, have one issue in common. In order to perform their assigned functions, they must maintain their structural integrity and be reliable and durable during their entire designed service life. Thus, strength, durability, and time-dependent mechanical property degradation are major concerns for design engineers and device manufacturers, even though the parts are designed for electronic, magnetic, optical or other functions.
