This volume differs somewhat from the previous volumes in the series in that there is a strong emphasis on the physical aspects and not so much on the chemical aspects of intermetallic compounds. Two of the chapters are concerned with relatively new experimental methods of studying rare earth metallic phases - high energy neutron spectroscopy and light scattering. In these chapters the authors explain the new kinds of information one obtains from these techniques and how this complements the knowledge previously gleaned from the more common measurements - such as NMR, heat capacities, magnetic susceptibility, transport and elastic properties. One of the remaining three chapters deals with NMR studies of rare earth intermetallics and the final two chapters are concerned, not so much with a particular experimental technique, but with physical phenomena that occur in these compounds: the electron-phonon interaction and heavy fermion behavior.

This thesis presents studies on the interaction of soft materials like surfactants and proteins with hard silica nanomaterials. Due to its interdisciplinary nature it combines concepts from the fields of physical chemistry, nanoscience and materials science, yielding to fundamental insights into the structure-directing forces operating at the nano-scale. It is shown that the morphology of surfactant micellar aggregates adsorbed at the surface of nanoparticles and inside tubular nanopores can be tuned on demand by the co-adsorption of a surface modifier. The interaction of globular proteins with silica nanoparticles is dominated by electrostatic interactions and can be controlled by pH and ionic strength, while the bridging of nanoparticles by adsorbed protein molecules leads to large-scale hybrid aggregates of protein with the nanoparticles. Concepts emerging from the role of electrostatic interactions in the hetero-aggregation of nanoparticles with protein molecules are used for the co-assembly of charged microbeads into linear clusters and chains of controllable length.

This volume chronicles the proceedings of the 8th International Symposium on Surfactants in Solution (SIS) held in Gainesville, FL, June 10-15, 1990. This series of symposia have been smoothly running since 1976, but the appellation "Surfactants in Solution" was used for the first time in 1982 in Lund. Since then our logo "SIS" has become very familiar to everyone involved in surfactants. In Lund the meeting was billed as the Fourth International Symposium on Surfactants in Solution. Earlier three events were held under different rubrics, but proceedings of all these symposia, except the 7th SIS held in Ottawa in 1988, have been properly documented. As a matter of fact so far 10 volumes have appeared under the title "Surfactants in Solution". 1,2,3 The program for the 9th SIS was very comprehensive and many ramifications of surfactants were covered, and it was a veritable international event. It contained a total of 384 papers by 869 authors from practically every corner of our planet. Just the sheer number of papers is a testimonial to the high tempo of research and tremendous interest in this wonderful class of materials. As in the past, there were plenary lectures (5), invited talks (37), oral presentations (195) and poster presentations (147). The plenary lectures were given by Prof. J. Th. G. Overbeek, Prof. C. A. Bunton, Prof. H. Ti Tien and Dr. J. Swalen. The lecture by Prof. Overbeek, the doyen of surface and colloid science, was a real treat.

Modeling Chemical Systems using Cellular Automata provides a practical introduction to an exciting modeling paradigm for complex systems. The book first discusses the nature of scientific inquiry using models and simulations, and then describes the nature of cellular automata models. It then gives detailed descriptions, with examples and exercises, of how cellular automata models can be used in the study of a wide variety chemical, physical, and biochemical phenomena. Topics covered include models of water itself, solution phenomena, solution interactions with stationary systems, first- and second-order kinetic phenomena, enzyme kinetics, vapor-liquid equilibrium, and atomic and molecular excited-state kinetics. The student experiences these systems through hands-on examples and guided studies. This book is the first of its kind: a textbook and a laboratory manual about cellular automata modeling of common systems in chemistry. The book is designed to be used as a text in undergraduate courses dealing with complex systems and/or as a computational supplement to laboratory courses taught at the undergraduate level. The book includes: - Compact descriptions of a large variety of physical and chemical phenomena - Illustrative examples of simulations, with exercises for further study - An instructor's manual for use of the program The book will be of great value in undergraduate courses in chemistry, physics, biology, applied mathematics, and bioinformatics, and as a supplement for laboratory courses in introductory chemistry, organic chemistry, physical chemistry, medicinal chemistry, chemical engineering and other courses dealing with statistical and dynamic systems. It allows the exploration of a wide range of dynamic phenomena, many of which are not normally accessible within conventional laboratory settings due to limitations of time, cost, and experimental equipment. The book is both a textbook on applied Cellular Automata and a lab manual for chemistry (physics, engineering) courses with lab activity. It would supplement other lab work and be an additonal book the students would use in the course. The authors have assessed the emerging need for this kind of activity in science labs because of the cost of the practical activitites and the frequent failure of some exercises leading to lost didactic value of some experiments. This book is pioneering an alternative that will grow in use. There are no course directors who would use Cellular Automata exclusively. The authors see an emerging interest in this kind of work in courses that contain lab exercises. One such course is the graduate course that Lemont Kier gives in Life Sciences about complexity. He uses many examples and studies from Cellular Automata in the latter part of this course.

Molecular Theory of Solvation presents the recent progress in the statistical mechanics of molecular liquids applied to the most intriguing problems in chemistry today, including chemical reactions, conformational stability of biomolecules, ion hydration, and electrode-solution interface. The continuum model of "solvation" has played a dominant role in describing chemical processes in solution during the last century. This book discards and replaces it completely with molecular theory taking proper account of chemical specificity of solvent.

The main machinery employed here is the reference-interaction-site-model (RISM) theory, which is combined with other tools in theoretical chemistry and physics: the ab initio and density functional theories in quantum chemistry, the generalized Langevin theory, and the molecular simulation techniques.

This book will be of benefit to graduate students and industrial scientists who are struggling to find a better way of accounting and/or predicting "solvation" properties.

The role of chemistry in materials processing and performance, at high temperatures, is a key area in today's technology. High temperature chemistry-the combination of inorganic chemistry with high temperatures-has undergone dramatic growth within the past 50 years.
The papers in Materials Chemistry at High Temperatures highlight, in two outstanding volumes, the latest information and techniques in this fast-paced field.
Essential reading for anyone involved in this innovative technology!

'Shape in Chemistry' looks at molecular shape from a unique perspective: It introduces the reader to the topological concepts and methods of precise shape characterization that are applicable for direct, non-visual description and analysis of general molecular shapes. The author provides a pictorial introduction to all the topological tools necessary for the subjects discussed. Mathematical description is also provided at an easily comprehensible level. New concepts are introduced beginning at the familiar level of stereochemistry and lead on to more advanced topological shape analysis methods. The structure of the book reflects the author's desire to bring the reader to an early appreciation of the power of topology in chemistry. After a brief review of the quantum chemical concept, the author compares the merits of visual, computer graphics methods and nonvisual, algorithmic shape analysis methods. The book ends with the concepts of approximate symmetry and various generalizations of symmetry. 'Shape in Chemistry' is surely destined to become standard reading in the field. It presents a valuable addition to the literature on shape and modeling of molecules for non-specialists organic, physical and medical chemists, researchers in various aspects of QSAR and pharmacological drug design and advanced undergraduate and graduate students.

The progress that has recently been made in the field and applications of thermochemistry, having as a consequence an in- crease in the interest of the subject, undoubtedly can be con- sidered highly remarkable. Traditionally, the thermochemist has provided accurate ther- mal data on chemicaZ compounds of practicaZ importance, mainly by calorimetric and by equilibrium studies. The scope has been considerably extended in recent years, following the development of microcalorimetric techniques, of flow calorimetry, of titra- tion calorimetry, and of high temperature calorimetry. The im- pact has been most noticeable in biochemical studies, in metallur- gical studies, and in organometallic and inorganic thermochemis- try. A parallel development has led to increasing output of signi- ficant thermal data on gas-phase transient species (e.g. free ra- dicals, radical ions) by kineticists, and by use of photoioniza- tion spectroscopy, mass spectroscopy and ion-cyclotron resonance spectroscopy. These species are outside the scope of traditional calorimetric study, but as more data on them become available they vastly add to the value of traditional thermochemical data and enable bond energies to be evaluated, and the inter-relation of molecular structure and bonding energy to be more closely exa- mined.

The chapters in this book are based upon lectures given at the NATO Advanced Study Institute on Synthetic Membranes (June 26-July 8, 1983, Alcabideche, Portugal), which provided an integrated presentation of syn thetic membrane science and technology in three broad areas. Currently available membrane formation mechanisms are reviewed, as well as the manner in which synthesis conditions can be controlled to achieve desired membrane structures. Membrane performance in a specific separa tionprocess involves complex phenomena, the understanding of which re quires a multidisciplinary approach encompassing polymer chemistry, phys ical chemistry, and chemical engineering. Progress toward a global understanding of membrane phenomena is described in chapters on the principles of membrane transport. The chapters on membrane processes and applications highlight both established and emerging membrane processes, and elucidate their myriad applications. It is our hope that this book will be an enduring, comprehensive compen dium of the state of knowledge in the field of synthetic membranes. We have been encouraged in that hope by numerous expressions of interest in the book, coming from a variety of potential users."

Presenting a comprehensive account of the physical concepts and theoretical approaches developed for the study of the dynamical properties of liquids (or, more generally, of high-density fluids), at a microscopic level, this book first discusses the basic dynamical phenomena to be interpreted, as well as the various experimental probes. It then proceeds to an exposition of the sophisticated theoretical techniques needed for a satisfactory account of both single particle and collective motions. The complications are faced in a stepwise fashion, with special attention to the physical content of the results. Based on the results of the progress achieved in the last decade the book provides a satisfactory understanding of most of the phenomena characterising this fascinating field.

CARGESE INSTITUfE ON DISORDER AND MIXING Convection, diffusion and reaction are the three basic mechanisms in physico-chemical hydrodynamics and chemical engineering. Both convective and diffusive processes are strongly influenced by the effect of disorder of granular matter in porous media, suspensions, fluidized beds or/and by the randomness caused in turbulent flow field. This book has been initiated by a NATO summer institute held in Cargese (Corsica, FRANCE) from June 15 th to 27 th 1987 . Its aim was to associate statistical physicists, fluid mechanicians and specialists of chemical engineering on the problems of the relation between disorder and mixing and, in this respect, this is a " premiere ." This book is made of chapters based on lectures given in the meeting. However we have paid a considerable attention to harmonize the contents and styles of chapters made by scientists trained in different communities and using different languages and techniques to describe similar problems. The Prelude by the editors of the book introduces the different points and is a biased view of some of the important and most active aspects of the subjects developed. We wish to thank all contributors and students of the institute who gave the style of the present interdisciplinary approach. We also greatly thank Elisabeth Charlaix who has shared with us the scientific and practical organisation of the institute, and Marie-France Hanseler for her technical support.

Fisheries genetics researchers will find invaluable the thirty-eight peer-reviewed contributions in this book, presented at the 20th Lowell Wakefield Fisheries Symposium "Genetics of Subpolar Fish and Invertebrates," held in May 2002 in Juneau, Alaska. Looming over concerns of lost fisheries stocks and persistent erosion of genetic variability are predictions of global warming, which may further tax genetic resources. One consequence is an increased reliance on genetic applications to many aspects of fisheries management, aquaculture, and conservation. The contributions in this book are important to modern fisheries science and genetics, and illustrate the evolution of the field over the past decade. The improved technology provides tools to address increasingly complicated problems in traditional applications and ecological and behavioral studies. The union between molecular and quantitative genetics, where many of the major questions about population structure and evolution remain unanswered, will also benefit from the new technologies.

This IMA Volume in Mathematics and its Applications DYNAMICAL ISSUES IN COMBUSTION THEORY is based on the proceedings of a workshop which was an integral part of the 1989-90 IMA program on "Dynamical Systems and their Applications." The aim of this workshop was to cross-fertilize research groups working in topics of current interest in combustion dynamics and mathematical methods applicable thereto. We thank Shui-Nee Chow, Martin Golubitsky, Richard McGehee, George R. Sell, Paul Fife, Amable Liiian and Foreman Williams for organizing the meeting. We especially thank Paul Fife, Amable Liiilin and Foreman Williams for editing the proceedings. We also take this opportunity to thank those agencies whose financial support made the workshop possible: the Army Research Office, the National Science Foundation and the Office of Naval Research. Avner Friedman Willard Miller, Jr. ix PREFACE The world ofcombustion phenomena is rich in problems intriguing to the math ematical scientist. They offer challenges on several fronts: (1) modeling, which involves the elucidation of the essential features of a given phenomenon through physical insight and knowledge of experimental results, (2) devising appropriate asymptotic and computational methods, and (3) developing sound mathematical theories. Papers in the present volume, which are based on talks given at the Workshop on Dynamical Issues in Combustion Theory in November, 1989, describe how all of these challenges have been met for particular examples within a number of common combustion scenarios: reactiveshocks, low Mach number premixed reactive flow, nonpremixed phenomena, and solid propellants."

The book deals with various consequences of major nuclear accidents, such as in 1986 in Chernobyl and in 2011 in Fukushima. The public is extremely interested in learning more about the movements and risks posed by radiation in the environment related to food supply and food safety. Radionuclides are found in air, water, soil and even in us not only after nuclear accidents because they occur also in nature. Every day, we ingest and inhale radionuclides in our air and food and the water. This book provides a solid underpinning of the basic physical-chemistry and biogeochemistry of naturally occurring and anthrop radioactivity. The mechanisms of radioactive element transfer in the atmosphere, tropospheric and stratospheric diffusion of radioactivity, environmental contamination from accidents and the impact of atmospheric pollution on the food chain, soil and plants, are analyzed and the analytical methods are illustrated. The question of natural radioactivity concentration in building materials is addressed too. While the book contains many case studies and data for Greece, it is of general value. It contributes to the development of international environmentally safe standards and economically reasonable standard regulations based on justified radiological, social and economical legislation concepts.

"The Exploration of Supramolecular Systems and Nanostructures by Photochemical Techniques" provides a comprehensive view of the most commonly used photochemical and photophysical techniques and their applications to the study of supramolecular systems. Optical inputs are extremely powerful in the study of nanostructures since they can be used both to read the state of the system and to provide it energy to work.
After a brief introduction to the realm of photochemistry, electronically excited state formation and the different pathways of excited state deactivation, the book focuses on the theoretical basis and the practical aspects related to the most widely used photophysical and photochemical techniques, from absorption to time-resolved emission techniques with polarized light. Each chapter illustrates an example of the application of that particular technique to the study of a supramolecular system.
"The Exploration of Supramolecular Systems and Nanostructures by Photochemical Techniques" not only discusses the latest advances of the field of supramolecular photochemistry but it also offers technical and operative details useful in the laboratory. It is therefore suitable for both the novice and the expert.

Many books cover the determination of rate constants under different experimental conditions and different chemical composition of the reaction mixture in their formal treatment of thermal kinetics. However, most textbooks are limited to simple mechanisms. In contrast, analogous treatment of photochemical reactions is limited to the publication of special reactions and investigations. Therefore, this book is aimed at providing an overall description of formal photokinetics covering a wider scope than the usual books on kinetics.

This volume attempts to provide a concise treatment of both thermo- and photochemical reactions by means of generalised differential equations, their set-up in matrix notation, and their solution by a formalism using numerical integration. At a first glance this approach might be surprising. However, apart from the argument that the didactics of thermal reactions are easier to handle than those of kinetics, the book provides additional reasons in support of this approach. Therefore, the formalism derived allows the evaluation of photochemical reactions, which are superimposed thermal reactions taking into account that the amount of light absorbed varies during the reaction. Because of this, any approximation, either by using total absorbance or negligible absorbance, will cause considerable errors even for simple reactions. The approach chosen to transform the axis of the radiation time into a new variable that includes the photokinetic factor proves that formal kinetics can be applied to thermal and photochemical reactions as well, and even allows the handling of solutions that cannot be homogenised or solid samples in which the concentration varies locally.By using this approach to introduce partial photochemical quantum yields even complex mechanisms can be determined quantitatively.

A large number of examples for different mechanisms and an introduction to many spectroscopic and chromatographic methods suitable for photokinetic analyses are provided to enable the reader to carry out a step-by-step evaluation of his own measurements. To reduce the number of formula in some chapters an appendix has been included which contains a detailed description of the calculus of some essential examples. For the convenience of the reader the following has been included:

- A large number of examples describing the use of formula

- A detailed description of the procedure for applying photokinetics to complex consecutive photoreactions

- An Internet address where the reader can find a tutorial for this procedure:
http: //www.barolo.ipc.uni-tuebingen.de/tele/photokin/

- A simple macro to help in programming his own evaluation procedure.

The current state of the art of several aspects of minerals and petroleum is presented in this volume. It documents the proceedings of the Internationl symposium on Particle Technology and Surface Phenomena in Minerals and Petroleum sponsored by the Fine Particle Society (FPS). This meeting was held in San Diego, California, August 21-25, 1990. The symposium upon which this volume is based was organized in five sessions emphasizing various basic and applied aspects of research on minerals and petroleum technology. Major topics discussed involve surface phenomena in minerals, mineral flotation, characterization of aspaltenes, theoretical aspects of reservoir simulation, porosity, permeability, residual water saturation, hydrocarbon and gas potential in north slope Alaska, polymer/alkaline flooding, surfactant flooding and foam flooding for enhanced oil recovery. This edition includes eighteen selected papers presented in the symposium. These papers are divided in four broad categories: (1) Asphaltene Aggregation and Characterization, (2) Theoretical Aspects and Reservoir Characterization, (3) Colloidal Dispersions in Minerals/Petroleum, and (4) Surface Phenomena and Petroleum Recovery. Several mineral and oil recovery processes using various chemicals with special reference to surface phenomena and particle technology are described in these sections.

Besides its obvious destructive potential, military R&D also serves to protect human lives, equipment and facilities against the effects of weapons. Concepts have therefore been developed that improve safety of stationary and mobile facilities against pressure waves, thermal radiation and fire. Effective, fast fire extinguishing equipment has been designed for tank compartments and motors. Closed buildings are demolished and landmines are removed with gas and dust explosions. Stringent safety requirements have been developed for the production of ammunition and explosives. Military and related industries have accumulated a vast knowledge and sophisticated experience that are very valuable in a variety of civil applications. The knowledge is based on theoretical and experimental research work, the origin of which sometimes dates back many centuries. It has often been classified and therefore has remained unknown to the civilian population, until now.
