Surface Chemistry Theory and Applications focuses on liquid-gas, liquid-liquid, solid-gas, solid-liquid, and solid-solid surfaces. The book first offers information on liquid-gas surfaces, including surface tension, measurement of surface tension, rate of capillarity rise, capillary attraction, bubble pressure and pore size, and surface tension and temperature. The text then ponders on liquid-liquid and solid-gas surfaces. Discussions focus on surface energy of solids, surface roughness and cleanness, adsorption of gases and vapors, adsorption hysteresis, interfacial tension, and interfacial tension in multicomponent systems. The manuscript takes a look at solid-liquid surfaces, as well as stagnant layers at solid-liquid interfaces, heat transfer, surface roughness or electrodes, adsorption of liquids heat of wetting, and thin metal films condensed from vapor. The text also examines solid-liquid-gas and solid-liquid-liquid surfaces and electric surface phenomena. The book is a vital source of information for readers interested in surface chemistry.

Principles of Quantum Electrodynamics

Principles of Quantum Electrodynamics concentrates on one of the best understood parts of quantum field theory, quantum electrodynamics. It emphasizes the physical basis of the theory and avoids purely mathematical details. For this reason, the book should not be taken as a handbook of field theory, but rather as a compendium of the most characteristic and interesting results which have been obtained up to now. The book is organized into four parts. Part I develops the general mathematical framework, covering units and orders of magnitude, classical electrodynamics, and the general formalism of the quantum theory of fields. Part II deals with free fields. It examines some problems concerning the physical interpretation of the theory and asks whether the quantization procedure adopted actually introduces quantum characteristics and, if so, how these are expressed by the formalism. It also investigates the expectation values of more complicated expressions. Part III examines the effects of a mechanism which produces the particles under consideration; i.e., an external source of the fields. Part IV deals with quantum fields in interaction. The focus is on the case of a quantized electromagnetic field, the source of which is a quantized Dirac field.

Progress in Biophysics and Biophysical Chemistry, Volume 7 focuses on the applications of physical or physicochemical ideas and methods to biological problems, including the use of isotopes to investigate metabolic processes. Other subjects discussed in detail are the electric organs of fishes; the thermodynamics of agglutination of red cells; muscle structure and function; and the structure of bone. This book is comprised of seven chapters and begins with a review of the mechanisms of discharge of electric organs in fish in the contexts of general and comparative electrophysiology, paying particular attention to synaptic excitability and the involvement of several electrogenic components in the reflex discharge. The evolution of electric organs in fish is also discussed. The following chapters explore the thermodynamics of isohemagglutinins; use of labeled plasma proteins to study nutritional problems; use of isotopes to analyze intermediary metabolism; and X-crystal analysis of bone. The final two chapters are devoted to muscle structure and theories of contraction, chloroplast structure, and energy conversion in photosynthesis. This volume will be of interest to biophysicists, physicists, and physical chemists working with biological materials.

Electron Impact Phenomena and the Properties of Gaseous Ions, Revised Edition deals with data pertaining to electron impact and to molecular gaseous ionic phenomena. This book discusses electron impact phenomena in gases at low pressure that involve low-energy electrons, which result in ion formation. The text also describes the use of mass spectrometers in electron impact studies and the degree of accuracy obtained when measuring electron impact energies. This book also reviews relatively low speed electrons and the transitions that result in the ionization of the atomic system. This text then discusses diatomic molecules whose mass spectra can be interpreted using the Franck-Condon principle. This selection also presents some examples of ions in solution that resemble the gaseous ions formed by electron impacts. The energies of these gaseous ions can be the key to understanding the mechanisms of ionic reactions. These examples include the olefin addition reactions and catalytic cracking. This text will prove invaluable for research chemists, students, and professors in chemistry and related fields such as organic chemistry and electrochemistry.

Economics of Atomic Energy covers the historical developments and major trends in atomic energy and its utilization. This book is organized into three parts encompassing 10 chapters that emphasize the economic aspect of nuclear power. The first part provides an overview of the status of atomic industry, from uranium supply to production and uses of fissile materials. This part looks into the accurate measurement of the national incomes that have pressed ahead with atomic development and how much of the national resources have diverted to atomic research. The second part deals first with the increasing demand for cheaper energy, followed by the assessment of factors affecting the costs of nuclear reactor. The third part discusses Britain's atomic investment on research. This part also considers the other countries' atomic industry methods, including U.S.A., France, and Germany. This book will be of value to nuclear physicists, economists, and policy makers.

Atmospheric Electricity brings together numerous studies on various aspects of atmospheric electricity. This book is composed of 13 chapters that cover the main problems in the field, including the maintenance of the negative charge on the earth and the origin of the charges in thunderstorms. After a brief overview of the historical developments of atmospheric electricity, this book goes on dealing with the general principles, results, methods, and the MKS system of the field. The succeeding chapters are devoted to some aspects of electricity in the atmosphere, such as the occurrence and detection of ions, the air-Earth conduction current, and point-discharge and precipitation currents. These topics are followed by discussions on the maintenance of the Earth's charge; the correlation of Earth's charge with thunderstorm activity and current; and mechanism of charge transfer in nonstormy rain and snow. The concluding chapters consider the phenomena of thunder cloud and the lightning discharge. These chapters also examine various theories in understanding the separation of Earth's charge.

The Dynamics of Living Protoplasm provides an overview of the state of knowledge in the colloid chemistry of protoplasm that can help to interpret and explain some of the most puzzling and intriguing problems that physiologists have had to face. The book shows that there is now definite knowledge about the protoplasmic colloid, knowledge that provides a basis for an understanding of the mechanisms underlying vital activity. This knowledge is primarily of theoretical interest, but eventually it will help to solve problems of practical importance in the fields of human physiology, pharmacology, and pathology. The book opens with an introductory chapter on the study of protoplasm. This is followed by separate chapters on protoplasmic viscosity, protoplasmic gels, electrochemistry of the cell, the surface precipitation reaction, protoplasmic clotting, and muscular contraction. Subsequent chapters deal with the excitation of nerve, conduction and transmission, cell division and its suppression, stimulation and anesthesia, the colloidal theory of stimulation and anesthesia, and cellular homeostasis.
