During the last decades a considerable effort has been made on the computation of the isothermal flow of viscoelastic fluids. In fact the activities related to this particular field of non-Newtonian fluid mechanics have focused on the following questions: which type of constitutive equation describes non-Newtonian fluid behaviour; how to measure fluid parameters; and what type of computational scheme leads to reliable, stable and cost-effective computer programs. During the same period, typical non-Newtonian fluid phenomena have been experimentally examined, such as the flow through a four-to-one' contraction, the flow around a sphere or separation flow, providing fresh challenges for numerical modellers. Apart from momentum transport, however, fluid flow is strongly influenced by heat treansport in most real industrial operations in which non-Newtonian fluids are processed. The IUTAM Symposium on Numerical Simulation of Nonisothermal Flow of Viscoelastic Liquids' held at Rolduc Abbey in Kerkrade, the Netherlands, November 1--3, 1993, was organised to monitor the state of affairs in regard to the influence of nonisothermal effects on the flow of a viscoelastic liquid. The present collection of papers gives an overview of what has been achieved so far. It is a milestone in the rapidly emerging and exciting new field in non-Newtonian fluid mechanics.

This book treats the experimental methods used to determine the physical properties of explosives and explosions - physical principles, operating procedures and evaluations of results. Aimed at practicing engineers as well as experimental physicists who investigate the effects of explosions, this book will be of interest to research laboratories, manufacturers of explosives, military training establishments, technical laboratories and so forth.

Supercritical fluids which are neither gas nor liquid, but can be compressed gradually from low to high density, are gaining increasing importance as tunable solvents and reaction media in the chemical process industry. By adjusting the pressure, or more strictly the density, the properties of these fluids are customized and manipulated for the particular process at hand, be it a physical transformation, such as separation or solvation, or a chemical transformation, such as a reaction or reactive extraction. Supercritical fluids, however, differ from both gases and liquids in many respects. In order to properly understand and describe their properties, it is necessary to know the implications of their nearness to criticality, to be aware of the complex types of phase separation (including solid phases) that occur when the components of the fluid mixture are very different from each other, and to develop theories that can cope with the large differences in molecular size and shape of the supercritical solvent and the solutes that are present.

The value of the critical temperature (Tc), below which the thermal explosion of a chemical cannot occur, is indispensable to prevent such a chemical from exploding. In order to determine the Tc it has so far been necessary to measure the value in explosion experiments. Because of the inherent hazards, only few Tc values are available at present.

Critical Temperatures for the Thermal Explosion of Chemicals introduces new and simple procedures to calculate the Tc. As a result Tc can be calculated for a range of chemicals, many of which are listed in this new volume. The calculated values of Tc are shown to be in agreement with experimentally determined values.

The data and methods presented in Critical Temperatures for the Thermal Explosion of Chemicals will be of use to research laboratories as well as in the chemical industry.
* Introduces new and simple procedures for calculating critical temperatures
* Lists the T(c) values of chemicals in tables
* Explains mathematical expressions in clear simple terms

"Discusses the most recent advances in the correlations of structure and reactivity relationships of micelles, liposomes, microemulsions, and emulsions by thermal behavior measurements, as well as the options, scope, and limitations of the thermal behavior of dispersed systems. Highlights current studies on heterogeneous colloidal (dispersed) systems."

Nowadays, there are increasing demands for the control and specification of all aspects of industrial manufacturing. There is also a growing need to understand various biological processes and conditions for agricultural production, and concern for protection of the environment and human health. These factors have made it imperative to develop adequate methods for the analysis of gaseous substances or substances that can be converted to the gaseous state. It is not only necessary to apply known and developed methods correctly, but novel analytical procedures must also be found. Instrumentation should be improved and the applications of these methods will have to be extended.

The present volume provides a comprehensive description of the state-of-the-art and of future possibilities in the analysis of gaseous substances. In the individual chapters the following themes have been discussed; the theoretical basis for the methods, a description of the instrumentation and the steps necessary in actual analyses and an outline of the principal areas in which each method can be employed. Both classical methods that are still useful for the solution of analytical problems using simple instrumentation, and the newest methods in the field are described. Special attention is paid to modern electrochemical and spectroscopic methods, and to methods based on a number of physical principles. Gas chromatography is discussed in the greatest detail because of its specially important position in modern analytical chemistry.

The book should be well received by the analytical public and should be extremely useful to students and workers in scientific research laboratories and in fields dealing with environmental protection.

The first edition of this text, entitled Flame and Combustion Phenomena, was published by Professor John Bradley in 1969. Subsequent to John Bradley's untimely death, the second edition, Flame and Combustion, was published in 1985 by Professor John Barnard. The intention of my predecessors was that the book should be suitable for final year under graduates and as an introductory book about combustion phenomena for those involved in research and development in a wide range of disciplines. It is my hope that the same is true of this third edition, with particular attention paid to chemical aspects. The potential market for an introductory text has changed consider ably since the appearance of John Bradley'S monograph. There has been a considerable growth in concern for efficiency, safety and minimisation of the environmental impact of combustion, whereas the development of rocket fuels, explosives and propellants do not command the same intensity of effort as formerly. Thus, it seems prudent to shift the emphasis from some parts of the earlier texts, and to expand others that are more in line with current combustion activities."

On the day after the 1959 Cambridge Congress, during which the International Union of Pure and Applied Biophysics was founded, a biophysics section was formed within the Society of Physical Chemistry (Societe de Chimie Physique). Since then, three of the Society's annual meetings (the 11th, 17th, and 23rd) were devoted exclusively to the physico-chemical study of biological systems. The first of these was held in June 1961 at a hotel in Col de Voza, at the foot of an alpine glacier above Chamonix. The second, in May 1967, took place in the more learned setting of the venerable rooms of the National Museum of Natural History in Paris. The third - the one dealt with in the present volume - was recently held at Orleans-La Source in the newly built lecture theatres of the young University, which is near the great Institutes of the National Centre for Scientific Research (CNRS), on the Sologne plateau. These three stages are milestones of an evolution which characterises (at least schematically) the explosive evolution of biological physico-chemistry. The first colloquium, with the title 'Deoxyribonucleic Acid: Structure, Synthesis and Functions', actually marks the first contact of the physical chemist with one of the then most prestigious biological macromolecules, the structure of which had just been discovered, and in this way celebrated one of the first and most striking successes of molecular biology.

Introducing Biological Energetics is a novel, interdisciplinary text that presents biological understanding in terms of general underlying principles, treating energy as the overarching theme and emphasizing the all-pervading influence of energy transformation in every process, both living and non-living. Key processes and concepts are explained in turn, culminating in a description of the overall functioning and regulation of a living cell. The book rounds off the story of life with a brief account of the endosymbiotic origins of eukaryotic cells, the development of multicellularity, and the emergence of modern plants and animals.
Multidisciplinary research in science is becoming commonplace. However, as traditional boundaries start to break down, researchers are increasingly aware of the deficiencies in their knowledge of related disciplines. Introducing Biological Energetics redresses the reciprocal imbalance in the knowledge levels of physical and biological scientists in particular. Its style of presentation and depth of treatment has been carefully designed to unite these two readerships.

This book is a collection of selected papers presented at the symposium titled "In situ Spectroscopy in Monomer and Polymer Synthesis," held at the April, 2001 ACS National Meeting in San Diego, California, USA. The co-organizers of this symposium were Timothy Long, Judit E. Puskas, Robson F. Storey, and J. Andrews. In situ spectroscopic monitoring is gaining popularity both in academia and industry. FfIR monitoring is used most frequently, but UV-visible, raman, and NMR spectroscopy are also important. This book concentrates mostly on FfIR monitoring, both in the near and mid-infrared ranges. The first chapter is a short general overview of FfIR spectroscopy, followed by the symposium contribu tions. We thought that this would be especially useful for student readers. We hope that the book will present a state-of-the-art overview of research related to in situ spectroscopic monitoring. -Judit E.

The book deals with the most accurate method to describe thermodynamic property data, with empirical multiparameter equations of state. Due to new theoretical approaches, to increasing demands on the accuracy of thermodynamic property data, and to increasing computer power such equations became a valuable tool for every day calculations in scientific and engineering applications, rather than just the basis of printed property charts and tables. The book is dedicated both to users, who apply such formulations either in form of commercially available software or in form of programs written by themselves, and to scientists engaged in the development of empirical equations of state. Starting from a brief history, it covers the fundamentals of this subject as well as the most recent developments in the fields of highly accurate reference equations, of equations for advanced technical applications, and of the description of mixtures with multiparameter equations of state.

Complexity and Complex Thermoeconomic Systems describes the properties of complexity and complex thermo-economic systems as the consequence of formulations, definitions, tools, solutions and results consistent with the best performance of a system. Applying to complex systems contemporary advanced techniques, such as static optimization, optimal control, and neural networks, this book treats the systems theory as a science of general laws for functional integrities. It also provides a platform for the discussion of various definitions of complexity, complex hierarchical structures, self-organization examples, special references, and historical issues. This book is a valuable reference for scientists, engineers and graduated students in chemical, mechanical, and environmental engineering, as well as those in physics, ecology and biology, helping them better understand the complex thermodynamic systems and enhance their technical skills in research.

This book offers advanced students, in 7 volumes, successively characterization tools phases, the study of all types of phase, liquid, gas and solid, pure or multi-component, process engineering, chemical and electrochemical equilibria, the properties of surfaces and phases of small sizes. Macroscopic and microscopic models are in turn covered with a constant correlation between the two scales. Particular attention is given to the rigor of mathematical developments. This book focuses on solid phases.

In each generation, scientists must redefine their fields: abstracting, simplifying and distilling the previous standard topics to make room for new advances and methods. Sethna's book takes this step for statistical mechanics--a field rooted in physics and chemistry whose ideas and methods< br> are now central to information theory, complexity, and modern biology. Aimed at advanced undergraduates and early graduate students in all of these fields, Sethna limits his main presentation to the topics that future mathematicians and biologists, as well as physicists and chemists, will find< br> fascinating and central to their work. The amazing breadth of the field is reflected in the author's large supply of carefully crafted exercises, each an introduction to a whole field of study: everything from chaos through information theory to life at the end of the universe.

Phase Diagrams and Thermodynamic Modeling of Solutions provides readers with an understanding of thermodynamics and phase equilibria that is required to make full and efficient use of these tools. The book systematically discusses phase diagrams of all types, the thermodynamics behind them, their calculations from thermodynamic databases, and the structural models of solutions used in the development of these databases. Featuring examples from a wide range of systems including metals, salts, ceramics, refractories, and concentrated aqueous solutions, Phase Diagrams and Thermodynamic Modeling of Solutions is a vital resource for researchers and developers in materials science, metallurgy, combustion and energy, corrosion engineering, environmental engineering, geology, glass technology, nuclear engineering, and other fields of inorganic chemical and materials science and engineering. Additionally, experts involved in developing thermodynamic databases will find a comprehensive reference text of current solution models.

In Flame Structure and Processes, renowned physical chemist Robert M. Fristrom comprehensively documents the numerous experimental techniques used to study flame microstructure, and provides an interdisciplinary overview of how such research is revealing exciting new information about combustion and high temperature processes. Using premixed laminar flames as models for studying individual high temperature chemistries, physical processes, and their interactions, Fristrom expertly details experimental and mathematical methods for analyzing overall flame structure or any other high temperature reacting flow system. Specialized techniques required to obtain high spatial resolution under extreme temperature conditions are also described. Fristrom goes on to discuss what is currently known about flame chemistry, physical processes common to all flames, and combustion. An extensive bibliography and many useful tables round out the book. The only up-to-date book solely devoted to flame structure and processes, this book will be welcomed by students and professionals in chemical/mechanical engineering and physical chemistry.

RELATIVISTIC EFFECTS IN CHEMISTRY

This century's most famous equation, Einstein's special theory of relativity, transformed our comprehension of the nature of time and matter. Today, making use of the theory in a relativistic analysis of heavy molecules, that is, computing the properties and nature of electrons, is the work of chemists intent on exploring the mysteries of minute particles.

The first work of its kind, Relativistic Effects in Chemistry details the computational and analytical methods used in studying the relativistic effects in chemical bonding as well as the spectroscopic properties of molecules containing very heavy atoms. The second of two independent volumes, Part B: Applications contains specific experimental and theoretical results on the electronic states of molecules containing very heavy atoms as well as their spectroscopic properties and electronic structures. The first one-volume catalog of comprehensive computational results, Part B details:

• the relativistic effects on the electronic structure of transition metal clusters, such as the Cu, Ag, and Au triad
• the electronic structure of open-shell transition metal clusters such as Rh3 and Ir3
• the electronic and spectroscopic properties of heteronuclear diatomics of main group p-block elements from Ga to Po, especially the diatomic hydrides, halides, and chalconides
• the clusters of the very heavy main group p-block elements from Ga to Po
• the relativistic effects on molecules containing lanthanide and actinide atoms, including metals inside fullerenes.

An extraordinary new examination of Periodic Table elements, Part B of Relativistic Effects in Chemistry is also evidence of the enduring influence of Einstein's revolutionary theory.

This textbook introduces thermodynamics with a modern approach, starting from four fundamental physical facts (the atomic nature of matter, the indistinguishability of atoms and molecules of the same species, the uncertainty principle, and the existence of equilibrium states) and analyzing the behavior of complex systems with the tools of information theory, in particular with Shannon's measure of information (or SMI), which can be defined on any probability distribution. SMI is defined and its properties and time evolution are illustrated, and it is shown that the entropy is a particular type of SMI, i.e. the SMI related to the phase-space distribution for a macroscopic system at equilibrium. The connection to SMI allows the reader to understand what entropy is and why isolated systems follow the Second Law of Thermodynamics. The Second Llaw is also formulated for other systems, not thermally isolated and even open with respect to the transfer of particles. All the fundamental aspects of thermodynamics are derived and illustrated with several examples in the first part of the book. The second part addresses important applications of thermodynamics, covering phase transitions, mixtures and solutions (including the Kirkwood-Buff approach and solvation thermodynamics), chemical equilibrium, and the outstanding properties of water.This textbook is unique in two aspects. First, thermodynamics is introduced with a novel approach, based on information theory applied to macroscopic systems at equilibrium. It is shown that entropy is a particular case of Shannon's measure of information (SMI), and the properties and time evolution of the SMI are used to explain the Second Law of Thermodynamics. This represents a real breakthrough, as classical thermodynamics cannot explain entropy, nor clarify why systems should obey the Second Law. Second, this textbook offers the reader the possibility to get in touch with important and advanced applications of thermodynamics, to address the topics discussed in the second part of the book. Although they may go beyond the content of a typical introductory course on thermodynamics, some of them can be important in the curriculum chosen by the student. At the same time, they are of appealing interest to more advanced scholars.

As the title suggests, this unique book describes the synthesis, structure and properties of the polyamide family known by the common term n-nylon. Each nylon from n=1 to n=22 is discussed in detail with descriptions of the preparation of monomers, various synthetic approaches to the polymerization, structure and crystallisation of polymers and both their fundamental properties and important technological properties. It treats the structure and properties from two perspectives, namely the effect of the aliphatic chain length between amide groups and the effects of the rigidity or flexibility of the main chain Whilst intended as a reference work for all polymer scientists, in academia and industry, working with nylons, polyamide and condensation polymers, n-Nylons will also be appreciated by post-graduate students of polymer science and engineering. Each self-contained chapter can be read individually and is extensively referenced.

Small systems are a very active area of research and development due to improved instrumentation that allows for spatial resolution in the range of sizes from one to 100 nm. In this size range, many physical and chemical properties change, which opens up new approaches to the study of substances and their practical application. This affects both traditional fields of knowledge and many other new fields including physics, chemistry, biology, etc. This book highlights new developments in statistical thermodynamics that answer the most important questions about the specifics of small systems - when one cannot apply equations or traditional thermodynamic models.

This book provides an accessible yet thorough introduction to thermodynamics, crafted and class-tested over many years of teaching. Suitable for advanced undergraduate and graduate students, this book delivers clear descriptions of how to think about the mathematics and physics involved. The content has been carefully developed in consultation with a large number of instructors, teaching courses worldwide, to ensure wide applicability to modules on thermodynamics. Modern applications of thermodynamics (in physics and related areas) are included throughout-something not offered to the same degree by existing texts in the field. Features: A sophisticated approach to the subject that is suitable for advanced undergraduate students and above Modern applications of thermodynamics included throughout To be followed by volumes on statistical mechanics, which can be used in conjunction with this book on courses which cover both thermodynamics and statistical mechanics

This book covers the results of investigations into the mechanisms and kinetics of thermal decompositions of solid and liquid substances on the basis of thermochemical analyses of the processes. In the framework of the proposed ideas, the main features of these reactions are explained and many problems and unusual phenomena, which have accumulated in this field, are interpreted. New methods of TA measurement and calculation have been developed, which permit the precision and accuracy of determination of kinetic parameters to be increased substantially. Reliable kinetic characteristics have been obtained and the decomposition mechanisms for several tens of substances have been interpreted. These include different classes of compounds: crystalline hydrates, oxides, hydroxides, nitrides, azides, nitrates, sulfates, carbonates and oxalates.

A much-needed expansion of traditional chemical thermodynamic concepts--essential reading for today's advanced students and research professionals
Reflecting the current operational practice of chemistry, this unique book provides an important update of traditional chemical thermodynamics, especially the thermodynamics of liquid solutions. Using a flexible composition model that enumerates both the formal components of a system and the molecular species derived from them, Thermodynamics of Molecular Species introduces a set of general theorems and proofs that address a range of significant phenomena beyond the reach of traditional chemical thermodynamics, such as enthalpy-entropy compensation, molar shifts, and thermodynamic error tolerance. Dr. Grunwald's novel approach creates a natural framework for mechanistic studies of molecular phenomena, while at the same time avoiding some of the complexity of statistical thermodynamics. The book's features include:
* A broad definition of molecular species that includes all participants in reaction mechanisms: reactants, products, substrates, catalysts, reactive intermediates, and transition states
* Solid experimental evidence supported by explicit examples across a breadth of areas--including solvation, water and aqueous solutions, environmental isomers, ions, and ion pairs
* Thermodynamic aspects of interionic attraction theory and of structure-energy correlations
* Almost 100 figures and diagrams that express abstract and mathematical ideas in clear and concrete terms
