Fluid Transport in Nanoporous Materials : Proceedings of the NATO Advanced Study Institute, held in La Colle sur Loup, France, 16-28 June 2003
The most promising include molecular sieves which are being developed as inorganic or polymeric systems with 0. 3-30nm in pore dimensions. These nanoporous solids have a broad spectrum of applications in chemical and biochemical processes. The unique applications of molecular sieves are based on their sorption and transport selectivity. Yet, the transport processes in nanoporous systems are not understood well. At the same time, the theoretical capabilities have increased exponentially catalyzed by increases in computational capabilities. The interactions between a diffusing species and the host solid are being studied with increasing details and realism. Further, in situ experimental techniques have been developed which give an understanding of the interactions between diffusing species and nanoporous solids that was not available even a few years ago. The time was ripe to bring together these areas of common interest and study to understand what is known and what has yet to be determined concerning transport in nanoporous solids. Molecular sieves are playing an increasing role in a broad range of industrial petrochemical and biological processes. These include shape-selective separations and catalysis as well as sensors and drug delivery. Molecular sieves are made from inorganic as well as organic solids, e. g. , polymers. They can be employed in packed beds, as membranes and as barrier materials. Initially, the applications of molecular sieves were dominated by the use of zeolites.

A large section is devoted to the description of the renewable resources of flavours: spice plants, fruits from moderate to tropical climates, vegetables, fermented and heated plants. Analytical methods, such as gas chromatography coupled to human or electronic noses or to a mass spectrometer, are outlined and consumer trends, legal and safety aspects are described. Novel renewable resources come from biotechnology.
Fire properties of polymer composite materials
This book is the first to deal comprehensively with the important topic of the fire behaviour of polymer composite materials. Composites are used in a diverse range of applications, including land and marine transport, aerospace, the chemical industry, and most branches of civil engineering infrastructure. It is our belief that fire behaviour is the single most important factor limiting the wider use of composites in many of these areas. Our aim in producing this volume is therefore to stimulate the work that is needed to overcome this fundamental problem. The first step in such a journey is, of course, to summarise what is presently known, which is what we have attempted here. The book covers all of the key issues on the behaviour of polymer composites in fire.
Ferro- and Antiferroelectricity : Order/Disorder versus Displacive
Solid-state systems are frequently classi?ed according to their physical, str- tural or chemical properties. Such schemes are extremely helpful since pr- erties related to any such classi?cation are typically known and facilitate id- tifying solids with special material classes. The best-known examples of these schemes are conductivity or resistivity measurements by means of which m- als are easily distinguishable from insulators. However, frequently clear-cut decisions between material classes are not possible, since anisotropy, chemical composition, binding forces and local effects wash out distinct properties and lead to competition or coexistence. Such unresolved situations are especially typical for transition metal oxides that exhibit a variety of ground-state properties in a fascinating way.
Femtosecond laser spectroscopy
As concepts and methodologies have evolved over the past two decades, the realm of ultrafast science has become vast and exciting and has impacted many areas of chemistry, biology and physics, and other fields such as materials science, electrical engineering, and optical communication. The field has recently exploded with the announcement of a series of remarkable new developments and advances. This volume surveys this recent growth in eleven chapters written by leading international researchers in the field. It includes sections on femtosecond optical frequency combs, soft x-ray femtosecond laser sources, and attosecond laser sources. In addition, the contributors address real-time spectroscopy of molecular vibrations with sub-5-fs pulses and multidimensional femtosecond coherent spectroscopies for studying molecular and electron dynamics. Novel methods for measuring and characterizing ultrashort laser pulses and ultrashort pulses of light are also described. The topics covered are revolutionizing the fields of biomedical imaging, electron dynamics, ultrahigh precision spectroscopy, and optical frequency metrology. Surveying the latest advances in ultrafast lasers, Femtosecond Laser Spectroscopy will be of interest to both researchers and graduate students.
Fast Reactions in Energetic Materials : High-Temperature Decomposition of Rocket Propellants and Explosives
Modern energetic materials include explosives, blasting powders, pyrotechnic m- tures and rocket propellants [1, 2]. The study of high-temperature decomposition of condensed phases of propellants and their components (liquid, solid and hybrid) is currently of special importance for the development of space-system engineering [3, 4]. To better understand the burning mechanisms (stationary, nonstationary, - steady) of composite solid propellants and their components, information about the macrokinetics of their high-temperature decomposition is required [5]. To be able to evaluate the ignition parameters and conditions of safe handling of heat-affected explosives, one needs to know the kinetic constants of their high-temperature - composition. The development of new composite solid propellants characterized by high performance characteristics (high burning rates, high thermal stability, stability to intrachamber perturbations, and other aspects) is not possible without quanti- tive data on the high-temperature decomposition of composite solid propellants and their components [6].

Evolution of Thin Film Morphology : Modeling and Simulations
Thin film deposition is the most ubiquitous and critical of the processes used to manufacture high tech devices. Morphology and microstructure of thin films directly controls their optical, magnetic, and electrical properties. This book focuses on modeling and simulations used in research on the morphological evolution during film growth. The authors emphasize the detailed mathematical formulation of the problem both through numerical calculations based on Langevin continuum equations, and through Monte Carlo simulations based on discrete surface growth models when an analytical formulism is not convenient. Evolution of Thin-Film Morphology will be of benefit to university researchers and industrial scientists working in the areas of semiconductor processing, optical coating, plasma etching, patterning, micro-machining, polishing, tribology, and any discipline that requires an understanding of thin film growth processes.
Esterification of Polysaccharides
Polysaccharide esters (cellulose and starch) are among the first polymeric materials applied commercially. The way of producing these technically relevant derivatives, mainly the carboxylic acid esters of C2 to C4 acids, have not been changed significantly during their history of manufacture. The investigation of new acylation methods and strategies of analysis was revived during the last decade by the search for tailored, biocompatible, material for specific fields of application, e.g., biotechnology, sensor technique and medicine. Unconventional solvents were developed for completely homo-geneous acylation reaction applying state of the art techniques of modern organic chemistry for polysaccharide modification. This book will provide a first comprehensive summary of acylation methods in a very practical manner. Detailed structure analysis is indispensable for the evaluation of structure-property-relationships. Spectroscopic methods in particular FTIR- and NMR spectroscopy including two dimensional methods are of increasing importance.

Essays in Brewing Science
Essays in Brewing Science is an original and comprehensive examination of brewing from the perspective of a real brewer. Brewing texts generally use a sequential barley-beer-bottle organization that takes the reader systematically through the various stages of beer-making in a logical and informative way. This approach adequately communicates the essential operation. However, brewers think about all of the stages in the process that might affect a single property, such as beer color. Alternatively brewers might ponder the influence of such affective agents as modification or oxygen throughout the process.
Equilibrium Between Phases of Matter : Phenomenology and Thermodynamics
The phase behaviour of materials and their thermodynamic properties are a central subject in all fields of materials research. The first Volume of the work, meant for graduate students in chemistry, geology, physics, and metallurgy, and their engineering counterparts, is split up in three levels, such that from level to level the portion and importance of thermodynamics and mathematics are increased. In the ground level it is shown that the basic principles of phase equilibria can be understood without the use of thermodynamics – be it that the concept of chemical potential is introduced right from the beginning. The intermediate level is an introduction to thermodynamics; culminating in the Gibbs energy as the arbiter for equilibrium – demonstrated for systems where the phases in equilibrium are pure substances. In the third level the accent is on binary systems, where one or more phases are solutions of the components.

The ?rst ?ve chapters are structured in the form of a textbook, going from the basic principles of enzyme structure and fu- tion to reactor design for homogeneous systems with soluble enzymes and hete- geneous systems with immobilized enzymes. The last chapter of the book is divided into six sections that represent illustrative case studies of biocatalytic processes of industrial relevance or potential, written by experts in the respective ?elds.
Environmental Technology in the Oil Industry
This significantly updated edition looks at each stage in the life cycle of petroleum products, from exploration to end use, examining the environmental pressures on the Oil Industry and its response. The Oil Industry produces a range of products without which modern civilization could not exist. Nevertheless, in today’s environmentally conscious world, society demands that the industry manufactures and markets the products without unduly polluting the environment. Its ability and willingness to comply determines whether society will allow it a licence to operate. Technical developments are progressing in line with environmental concerns and increasing sophistication of computer modelling techniques. These subjects are inter-related, but have often been dealt with independently.
