This monograph summarises results of research in some surface phenomena, observed in mechanical treatment and friction. In particular the book is devoted to urgent problems of the science of friction and wear and provides insight into the mechanism of the phenomena that cause, on the one hand, anomalously low coefficients of friction and wear (the so-called selective transfer) and on the other, dramatic damages of the surface layers during sliding (hydrogen wear of metals). The nature of metal interaction during sliding in selective transfer and hydrogen wear modes is analysed in detail. Furthermore results of studies concerned with certain aspects of phenomena appearing in the process of influencing contacting surfaces and with detecting the relationship between the observed characteristics and behavior of investigated materials in the process of mechanical treatment and friction are presented. The principle followed is to combine varied experimental facts, physical concepts and investigation methods, which at first sight appear to be unrelated, and using this approach to determine general rules. Chapter one provides the reader with a general understanding of fundamental surface phenomena which provide the background to their dynamic interaction in mechanical treatment and under friction. Chapter two deals with the laws governing influence of mechanical effects on the surface. The third chapter presents the fundamentals of the selective transfer theory under friction. Other chapters deal with the possibilities of the Mössbauer electron spectroscopy method, widely used in physics for solving tribology problems, the influence of external electromotive force sources on contact resistance and friction pairs' wear, and hydrogen wear of metals under friction.

This full-colour undergraduate textbook, based on a two semester course, presents the fundamentals of biological physics, introducing essential modern topics that include cells, polymers, polyelectrolytes, membranes, liquid crystals, phase transitions, self-assembly, photonics, fluid mechanics, motility, chemical kinetics, enzyme kinetics, systems biology, nerves, physiology, the senses, and the brain. The comprehensive coverage, featuring in-depth explanations of recent rapid developments, demonstrates this to be one of the most diverse of modern scientific disciplines. The Physics of Living Processes: A Mesoscopic Approach is comprised of five principal sections: • Building Blocks • Soft Condensed Matter Techniques in Biology • Experimental Techniques • Systems Biology • Spikes, Brains and the Senses The unique focus is predominantly on the mesoscale — structures on length scales between those of atoms and the macroscopic behaviour of whole organisms. The connections between molecules and their emergent biological phenomena provide a novel integrated perspective on biological physics, making this an important text across a variety of scientific disciplines including biophysics, physics, physical chemistry, chemical engineering and bioengineering. An extensive set of worked tutorial questions are included, which will equip the reader with a range of new physical tools to approach problems in the life sciences from medicine, pharmaceutical science and agriculture.

Surface phenomena in the field of high-temperature processes are attracting ever increasing attention on the part of scientific workers and engineers. In this field, many questions of applied science cannot properly be solved without taking into account the characteristics caused by surface phenomena at the various interfaces. The importance of surface phenomena in the pyrometallurgy of nonferrous and ferrous metals was convincingly demonstrated at a scientific conference on this problem held in Moscow towards the end of 1961. The English translation of the transactions of this conference, "Surface Phenomena in Metallurgical Processes, .. and its publication in the USA will ena ble American scientists and engineers working in the field of surface phenomena and metallurgy to acquaint themselves with the work of Russian investigators in this inter esting field of physical chemistry and the theory of metallurgical processes. In the Soviet Union, important groups of scientists in Moscow, Leningrad, Kiev, Sverdlovsk. and other cities are engaged in the study of surface phenomena as applied to the different branches of metallurgy. We trust that the publication of the American edition of the book "Surface Phenomena in Metallurgical Processes" will help to strengthen the scientific bonds between Soviet and American scientists.

This application-oriented book introduces readers to the associations and relationships between contact mechanics and friction, providing them with a deeper understanding of tribology. It addresses the related phenomena of contacts, adhesion, capillary forces, friction, lubrication, and wear from a consistent point of view. The author presents (1) methods for rough estimates of tribological quantities, (2) simple and general methods for analytical calculations, and (3) the crossover into numerical simulation methods, the goal being to convey a consistent view of tribological processes at various scales of magnitude (from nanotribology to earthquake research). The book also explores the system dynamic aspects of tribological systems, such as squeal and its suppression, as well as other types of instabilities and spatial patterns. It includes problems and worked-out solutions for the respective chapters, giving readers ample opportunity to apply the theory to practical situations and to deepen their understanding of the material discussed. The second edition has been extended with a more detailed exposition of elastohydrodynamic lubrication, an updated chapter on numerical simulation methods in contact mechanics, a new section on fretting in the chapter on wear, as well as numerous new exercises and examples, which help to make the book an excellent reference guide.

This book deals with the new and now-expanding field of friction, wear, and other surface-related mechanical phenomena for polymers. Polymers have been used in various forms such as bulk, films, and composites in applications where their friction, wear resistance, and other surface-related properties have been effectively utilized. There are also many examples in which polymers have performed extremely well, such as in tyres, shoes, brakes, gears, bearings, small moving parts in electronics and MEMS, cosmetics/hair products, and artificial human joints. Around the world, much research is currently being undertaken to develop new polymers, in different forms, for further enhancing tribological performance and for finding novel applications. Keeping in view the importance of tribology of polymers for research and technology as well as the vast literature that is now available in research papers and review articles, this timely book brings together a wealth of research data for an understanding of the basic principles of the subject./a

Physical Surfaces deals with the basic concepts of the physics of surfaces, including the nature of the surface pressure of unimolecular films and the equilibrium pressure of these films. The effect of particle size on capillary pressure, the surface energy and the cuticular energy of solids, and the fundamentals of wetting are also examined. This book is comprised of nine chapters and begins with a discussion on the mechanics and physical chemistry of liquid surfaces, with emphasis on capillarity and surface tension. The following chapters focus on liquid-liquid interfaces, foams and emulsions, and solid surfaces. Interfacial tension is analyzed in relation to miscibility and surface tension, along with contact angles in gas-liquid-liquid systems. The chapter on wetting looks at theories of contact angle, its measurement, and hysteresis. Adsorption and electric surface phenomena are also explored, together with adhesion and friction. This monograph will be a valuable resource for physical chemists and physicists.
