Characterization of Corrosion Products on Steel Surfaces
It is well known that corrosion products, i.e. rust, on iron and steel surfaces cannot be assigned a typical crystallographic structure with long-range order. In fact, the structure of rust is considered to be very complicated, and some forms of rust are assigned to the amorphous state for this reason. Accurate information about the atomic-scale structure of rust is important to shed light on corrosion mechanisms of metallic materials. And, since life of steel structures is often dominated by environmental degradation or corrosion of the surface, the structure of the rust formed on iron and steel surfaces during prolonged exposure to air is of great interest. This book describes the fundamental aspects of materials characterization for the ferric oxyhydroxides formed on steel surfaces.
Cathodic Arcs : From Fractal Spots to Energetic Condensation
Cathodic Arcs: From Fractal Spots to Energetic Condensation is the first book in over a decade dedicated to the physics and technology of cathodic arcs. It includes a detailed account of arc history, a textbook-like introduction to cathode phenomena, and some basic physics of expanding plasmas; it deals with the infamous macroparticle issue and describes a host of practical plasma filter solutions. In contrast to previous books on cathodic arcs, the focus is on the relation of arc plasmas and their properties to surface modification and thin film deposition. The book contains sections on basic plasma physics and thin film materials science. It also deals with practical issues of coatings such as stress control and the often-underrated issue of the coating’s color. By stressing the fractal nature of cathode spots, the theme of fluctuations can be found throughout the book: fluctuations affect all plasma properties and thereby have consequences for plasma-based surface modifications and film growth.
Browning Agents and Active Particles : Collective Dynamics in the Natural and Social Sciences
Lays out a vision for a coherent framework for understanding complex systems'' (from the foreword by J. Doyne Farmer). By developing the genuine idea of Brownian agents, the author combines concepts from informatics, such as multiagent systems, with approaches of statistical many-particle physics. This way, an efficient method for computer simulations of complex systems is developed which is also accessible to analytical investigations and quantitative predictions. The book demonstrates that Brownian agent models can be successfully applied in many different contexts, ranging from physicochemical pattern formation, to active motion and swarming in biological systems, to self-assembling of networks, evolutionary optimization, urban growth, economic agglomeration and even social systems.
Beam Instrumentation and Diagnostics
This treatise covers all aspects of the design and the daily operations of a beam diagnostic system for a large particle accelerator. A very interdisciplinary field, it involves contributions from physicists, electrical and mechanical engineers and computer experts alike so as to satisfy the ever-increasing demands for beam parameter variability for a vast range of operation modi and particles. The author draws upon 40 years of research and work, most of them spent as the head of the beam diagnostics group at GSI. He has illustrated the more theoretical aspects with many real-life examples that will provide beam instrumentation designers with ideas and tools for their work.
Axions : Theory, Cosmology, and Experimental Searches
Axions are peculiar hypothetical particles that could both solve the CP problem of quantum chromodynamics and at the same time account for the dark matter of the universe. Based on a series of lectures by world experts in this field held at CERN (Geneva), this volume provides a pedagogical introduction to the theory, cosmology and astrophysics of these fascinating particles and gives an up-to-date account of the status and prospect of ongoing and planned experimental searches. Learners and practitioners of astroparticle physics will find in this book both a concise introduction and a current reference work to a showcase topic that connects the "inner space" of the elementary particle world with the "outer space" of the universe at large.
Aurora : Observing and Recording Nature's Spectacular Light Show
The uniquely beautiful light display of an aurora is the result of charged particles colliding with tenuous atmospheric oxygen and nitrogen, more than 60 miles above the Earth, when the magnetosphere is disturbed by changes in the solar wind. Often - and incorrectly - regarded as being confined to high northern and southern latitudes, major auroral displays are visible from even the southern USA and the south of England, and occur perhaps twenty times in each eleven-year sunspot cycle. This book describes the aurora from the amateur observational viewpoint, discusses professional studies of auroral and geomagnetic phenomena to put amateur work in context, and explains how practical observers can go about observing and recording auroral displays.
Atoms, molecules and photons : An introduction to atomic- molecular- and quantum physics
This introduction to Atomic and Molecular Physics explains how our present model of atoms and molecules has been developed over the last two centuries both by many experimental discoveries and, from the theoretical side, by the introduction of quantum physics to the adequate description of micro-particles. It illustrates the wave model of particles by many examples and shows the limits of classical description. The interaction of electromagnetic radiation with atoms and molecules and its potential for spectroscopy is outlined in more detail and in particular lasers as modern spectroscopic tools are discussed more thoroughly. Many examples and problems with solutions are offered to encourage readers to actively engage in experimentation.

Atomic spectroscopy : Introduction to the theory of hyperfine structure
Atomic Spectroscopy provides a comprehensive discussion on the general approach to the theory of atomic spectra, based on the use of the Lagrangian canonical formalism. This approach is developed and applied to explain the hydrogenic hyperfine structure associated with the nucleus motion, its finite mass, and spin. The non-relativistic or relativistic, spin or spin-free particle approximations can be used as a starting point of general approach. The special attention is paid to the theory of Lamb shift formation. The formulae for hydrogenic spectrum including the account of Lamb shift are written in simple analytical form. The book is of interest to specialists, graduate and postgraduate students, who are involved into the experimental and theoretical research in the field of modern atomic spectroscopy.
Atmospheric Aerosol Properties : Formation, Processes and Impacts
An increasing interest in studies of atmospheric aerosols in the context of their impact on the formation of climate, heterogeneous chemical reactions in the atmosphere affecting in particular the environmental quality, problems of visibility and human health is the cause of unusual scales of developments connected with studies of atmospheric aerosols. The necessity has arisen to analyze the latest results concerning, first of all, three aspects of the problems considered: 1. aerosol properties from data of complex field observational experiment; 2. processes of aerosol formation and interaction of aerosol with clouds, 3. aerosol as a climate-forming atmospheric component (including the problem of long-range transport). The monograph in hand is dedicated mainly to the problems of the impact of aerosol on climate processes in the atmosphere, from microphysical processes of formation and evolution of aerosol properties to the formation of macro-scale cloud sytems on aerosol particles.

Analytical Ultracentrifugation of Polymers and Nanoparticles
Analytical ultracentrifugation (AUC) is a powerful method for the characterization of polymers, biopolymers, polyelectrolytes, nanoparticles, dispersions, and other colloidal systems. The method is able to determine the molar mass, the particle size, the particle density and interaction parameters like virial coefficients and association constants. Because AUC is also a fractionation method, the determination of the molar mass distribution, the particle size distribution, and the particle density distribution is possible. A special technique, the density gradient method, allows fractionating heterogeneous samples according to their chemical nature that means being able to detect chemical heterogeneity.

Aerosol Optics : Light Absorption and Scattering by Particles in the Atmosphere
Provides a comprehensive review of available techniques for the remote sensing of aerosols. Although mostly satellite remote sensing is considered, ground-based techniques are also discussed.describes techniques for the determination of the column concentration of aerosol particles and their optical sizing using spaceborne optical instrumentation. The majority of the techniques described in this book use a so-called "library method". This method relies upon the precalculated top-of-atmosphere reflectances (TOAR) for vaious atmospheric aerosol types. The comparison of measured and calculated TOARS allows one to characterize the optically-equivalent aerosol state.
