Handbook on the Physics and Chemistry of Rare Earths: The Role of Rare Earths in Catalysis
Among the numerous applications of the rare-earth elements, the field of catalysis accounts for a large number. Catalysis represents approximately 20% of the total market sales of rare earths worldwide. As a matter of fact two main applications have been prominent in the last decades: zeolite stabilization for fluid cracking catalysts, and automotive post-combustion catalytic treatment. The oldest use of rare earths in catalysis deals with the structural and chemical stabilization of the zeolites for petroleum cracking applications. For a long time this has been an area of application for non-separated rare earths. The addition of several percent of rare earths in the pores of the zeolite results in a strong surface acidity, which is essential for an efficient conversion of high-weight molecules into lighter species, like low-octane fuel, even in the very aggressive conditions of the petroleum industry. The popular demand for high-quality air in spite of the traffic congestion in large cities resulted in larger and larger constraints in the emission exhaust from cars. Thus highly efficient catalysts have had to be designed, and due to the combination of its redox properties and very good thermal stability, cerium oxide has been since the beginning, early in the 1980s, a major component of the three-way catalysts (TWC) now used in all modern gasoline cars. The future of rare earths in catalysis is probably bright. The fact that approximately 400 patents are applied for yearly in the area since 1992 is an illustration of a very active area. Usage of rare earths in catalysis is expected to grow due to their highly specific properties. Instead of the physical properties used in electronic applications, one deals now with redox properties, water and thermal stability, coordination numbers and so forth. The rare earths are so specific in these properties that their use can hardly be avoided, not only for the beauty of academic studies but also for the development of industrial applications with immediate influence on everyday life. Careful control of the synthesis conditions and the definition of optimum composition in each case are the keys to the preparation of highly performing compounds for catalytic applications. They must actually be considered as high performance products with functional properties, and not just chemical species. Chapters devoted primarily to catalysis have been published in earlier volumes of the Handbook. In this volume several more are added. The first is an extension of the earlier chapter 43, on interactions at surfaces of metals and alloys, to reactions such as hydrogenation, methanation, ammonia synthesis, saturated hydrocarbon reactions, dehydrogenation of hydrogenated materials, hydrodesulfurization, and carbon monoxide oxidation. The second chapter reports on the wide variety of catalyzed reactions involving metals and alloys in the innovated form of metal overlayers or bimetallic compounds with some transition metals produced from ammonia solutions. This is followed by a chapter on catalysis with mixed oxides usually having perovskite or perovskite-related structures. Then follows a comprehensive discussion on the background and current role of cerium oxide and associated materials for post-treatment of exhaust gases for pollution control. These three-way catalysts (TWC) are designed to render harmless the CO, NOx, and unburned hydrocarbons from internal combustion engines. The next chapter considers the wide field of zeolite catalysts containing rare earths from their historic use in petroleum refining in the 1960s to other petrochemical and fine chemical applications today. The final chapter documents the use of the triflates (the trifluoro-methane-sulfonyl group which is a hard Lewis acid in both aqueous and organic solutions) as versatile catalysts in carbon-carbon bond-forming reactions. Their stability in the presence of water, in spite of their being hard Lewis acids, enhances their growing usefulness.

Stereoselective Heterocyclic Synthesis III
Keeping up with the advances in modern heterocyclic chemistry is essential for many of our colleagues in academia and industry. It is the aim of this series on Stereoselective Heterocyclic Synthesis to assist the chemical community in this respect by presenting a selection of exciting recent developments. As it was for the first two volumes (1997), the stereoselective synthesis of - or with the aid of - heterocycles is the common motif for all the chapters in this third volume. I am very glad that again leading researchers in this area have contrib- ed highly stimulating accounts with up-to-date coverage. Stereoselective Heterocyclic Synthesis 111 features chapters on Stereoselective Intramolecular J,3-Dipolar Cycloadditions by I. N. N. Nambothiiri and A. Hassner giving an in depth survey of the generation and synthetic application of valuable 1,3-dipoles, 4-Acetoxy- and 4-Cyano-12-dioxanes in Synthesis by C. J. Sinz and S. D. Rychnovsky presenting a comprehensive summary of the utility of the versatile title compounds in natural products synthesis, The Synthetic Potential of Three-Membered Ring Aza-Heterocycles by B. Zwanenburg and l? ten Holte highlighting the fascinating chemistry of aziridine and azirine carboxylic esters, and '(Synthesis of Medium-Sized Ring Lactams by U. Nubbemeyer discussing a wide range of modern strategies for the stereoselective preparation of these important heterocycles.

Der vorliegende Band 3 behandelt einige Sachgebiete, die nur indirekt mit dem chemischen Pflanzenschutz verbunden sind, aber unter die chemische Schadlings- bekampfung fallen. Andererseits werden Probleme, we1che durch den chemischen Pflanzenschutz aufgeworfen worden sind, kritisch dargestellt. Die meisten Themen sind nicht nur flir Spezialisten interessant, sondern wenden sich fast noch mehr an allgemein naturwissenschaftlich und okologisch interessierte Leser. Ein einleitender Aufsatz tiber den Pflanzenschutz in Vergangenheit, Gegen- wart und Zukunft beschreibt die Situation des Pflanzenschutzes, seine N otwendig- keit, aber auch seine UlJ.ausgewogenheit hinsichtlich der Anwendung umstrittener Produkte in verschiedenen Landern. Ein Beitrag tiber okonomische und okologische Wechselwirkungen zeigt wohl erstmals klar und allgemein verstandlich die unausbleiblichen Wechselwirkungen beim Kampf des Menschen urn bessere und reichlichere Nahrung. Gerade dieser Beitrag sOllte, wie der vorangehende, auch von Nicht-Fachleuten zur Kenntnis genommen werden, ehe vorschnell tiber die angeblich gedankenlose Zerstorung der Umwelt durch die Landwirtschaft und den mit ihr notwendig verbundenen chemischen Pflanzenschutz diskutiert wird. Pflanzenschutzforschung bleibt auf allen Gebieten des Pflanzenschutzes uner- HiBlich. Sie wird durch zahlreiche Faktoren in ihren Kosten schwer be1astet und durch eine mangelhafte Koordination gesetzgeberischer MaBnahmen in mehreren Landern verunsichert. Ein Beitrag tiber die Industrielle Pflanzenschutzforschung beleuchtet diese Problematik.

In this volume we present four selected contributions by well-known authors, each an authority in his ?eld. The ?rst chapter is devoted to the use of oximes in cycloadditions which leads to formationof isoxazolines and isoxazolidines and from there to synthesis of macrolides like amphotericin and of other natural products and bioactive molecules. Furthermore, 4+2 cycloadditions of nitrosoalkenes are also included. This chapter complements the one in the X Preface previous volume which discussed access to isoxazolines via nitroalkanes.

Production Practices and Quality Assessment of Food Crops: Plant Mineral Nutrition and Pesticide Management
Plants require nutrients in order to grow, develop and complete their life cycle. Mineral fertilizers, and hence the fertilizer industry, constitute one of the most imp- tant keys to the world food supplies. There is growing concern about the safety and quality of food. Carbon, hydrogen and oxygen, which, together with nitrogen, form the structural matter in plants, are freely available from air and water. Nitrogen, phosphorus and potassium, on the other hand, may not be present in quantities or forms sufficient to support plant growth. In this case, the absence of these nut- ents constitutes a limiting factor. The supply of nutrients to the plants should be balanced in order to maximise the efficiency of the individual nutrients so that these meet the needs of the particular crop and soil type. For example, it should be noted that EU-wide regulations are not designed to govern the specific details of mineral fertilizer use. Although plants receive a natural supply of nitrogen, phosphorus and potassium from organic matter and soil minerals, this is not usually sufficient to satisfy the demands of crop plants. The supply of nutrients must therefore be supplemented with fertilizers, both to meet the requirements of crops during periods of plant growth and to replenish soil reserves after the crop has been harvested. Pesticides are important in modern farming and will remain indispensable for the foreseeable future.

Processing by Centrifugation
This volume constitutes the proceedings of the Fourth International Workshop on Materials Processing at High Gravity, held at Clarkson University, May 29 to June 2, 2000. There were 73 attendees from 16 countries. Since the topics extended well beyond materials processing, it was felt appropriate to name this proceedings Centrifugal Processing. Processing by Centrifugation includes the traditional bench-scale centrifuges, as well as all rotating systems utilizing the centrifugal and Coriolis forces to provide unique performance. Centrifugation led to the formation of sticky porous Teflon membranes, as well as improved polymeric solar cells. Centrifugation on large equipment improved the chemical vapor deposition of diamond films, influenced the growth and dissolution of semiconductor crystals, and elucidated the influence of gravity on coagulation of colloidal Teflon. A million g centrifuge was constructed and used to study sedimentation in solids and to prepare compositionally graded materials and new phases. Rotation of a pipe about its axis allowed the casting of large-diameter metal alloy pipes as well as coating the interior of pipes with a cermet utilizing self-propagating high-temperature synthesis. Such coatings are highly corrosion and erosion resistant. Flow on a rotating disk was shown to be useful for process intensification, such as large-scale manufacturing of nano-particles, polymerization reactions, and heat & mass transfer. Several theoretical studies dealt with the influence of rotation on fluid convection on surfaces and in pipes, tubes, and porous media. These have applications to integrated-circuit chip manufacturing, alloy casting, oil production, crystal growth, and the operation of rotating machinery.

Biochemistry of Scandium and Yttrium, Part 2: Biochemistry and Applications
Biochemistry of Scandium and Yttrium gathers together existing knowledge about scandium and yttrium from a wide variety of disciplines. Part 2 addresses the biochemical aspects of these two elements, and the various medical and environmental applications. (Part 1 presents a comparative study of the physical and chemical properties of scandium and yttrium, looking at both their similarities and their differences.) While these elements are relatively rare in nature, these books will show that they have unusual physical and chemical properties, and a disproportionate number of important applications. Improved analytical techniques have revealed that scandium and yttrium are present throughout living matter, even though only a relatively limited number of species have been analyzed so far. This fact of course has far-ranging implications for biological and environmental concerns. The major impacts of scandium and yttrium in science, technology, and medicine will be of interest to a wide variety of researchers, including geochemists, inorganic and organic chemists, clinical biochemists, and those specializing in environmental protection.

The Ideal Result: What It Is and How to Achieve It
The Ideal Final Result introduces the TRIZ Inventive Problem Solving Process in a way that allows readers to make immediate use of its most basic concepts. The Ideal Final Result reviews the basics of this left brained, but at the same time, very creative process for problem solving that uses a basic algorithm developed through the study of millions of patents. As opposed to psychologically based tools relying on the generation of hundreds of ideas to be sorted through to find the few of value, TRIZ rigorously defines the problem and assists the problem owner in identifying the existing inventive principles that are already known to solve that class of problems. This book reviews the most basic of the TRIZ algorithm tools and provides templates for readers to use in analyzing their difficult problems and provides a mental framework for their solution. It also describes TRIZ techniques for basic strategic planning in a business sense.

Silicon-on-Insulator Technology: Materials to VLSI, Third Edition, retraces the evolution of SOI materials, devices and circuits over a period of roughly twenty years. Twenty years of progress, research and development during which SOI material fabrication techniques have been born and abandoned, devices have been invented and forgotten, but, most importantly, twenty years during which SOI Technology has little by little proven it could outperform bulk silicon in every possible way. The turn of the century turned out to be a milestone for the semiconductor industry, as high-quality SOI wafers suddenly became available in large quantities. From then on, it took only a few years to witness the use of SOI technology in a wealth of applications ranging from audio amplifiers and wristwatches to 64-bit microprocessors. This book presents a complete and state-of-the-art review of SOI materials, devices and circuits. SOI fabrication and characterization techniques, SOI CMOS processing, and the physics of the SOI MOSFET receive an in-depth analysis.

Unexploded Ordnance Detection and Mitigation
The chapters in this volume were presented at the July-August 2008 NATO Advanced Study Institute on Unexploded Ordnance Detection and Mitigation. The conference was held at the beautiful Il Ciocco resort near Lucca, in the glorious Tuscany region of northern Italy. For the ninth time we gathered at this idyllic spot to explore and extend the reciprocity between mathematics and engineering. The dynamic interaction between world-renowned scientists from the usually disparate communities of pure mathematicians and applied scientists which occurred at our eight previous ASI's continued at this meeting. The detection and neutralization of unexploded ordnance (UXO) has been of major concern for very many decades; at least since the First World war. UXO continues to be the subject of intensive research in many ?elds of science, incl- ing mathematics, signal processing (mainly radar and sonar) and chemistry. While today's headlines emphasize the mayhem resulting from the placement of imp- vised explosive devices (IEDs), humanitarian landmine clearing continues to draw signi?cant global attention as well. In many countries of the world, landmines threaten the population and hinder reconstruction and fast, ef?cient utilization of large areas of the mined land in the aftermath of military con?icts.

Strategies and Tactics in Organic Synthesis: Volume 5
A classic in the area of organic synthesis, Strategies and Tactics in Organic Synthesis provides a forum for investigators to discuss their approach to the science and art of organic synthesis. Rather than a simple presentation of data or a second-hand analysis, we are given stories that vividly demonstrate the power of the human endeavour known as organic synthesis and the creativity and tenacity of its practitioners. First hand accounts of each project tell of the excitement of conception, the frustration of failure and the joy experienced when either rational thought and/or good fortune give rise to successful completion of a project. In this book we learn how synthesis is really done and are educated, challenged and inspired by these stories, which portray the idea that triumphs do not come without challenges. We also learn that we can meet challenges to further advance the science and art of organic synthesis, driving it forward to meet the demands of society, in discovering new reactions, creating new designs and building molecules with atom and step economies that provide solutions through function to create a better world.

Catalysis in C1 Chemistry
Continuously increasing oil prices, a dwindling supply of petroleum, and the existence of extensive reserves of biomass, especially of coal, have given rise to a growing interest in generating CO/H from these sources. Catalytic reactions can 2 convert CO/H mixtures to useful hydrocarbons or hydrocarbon intermediates. 2 There is little doubt that petroleum will remain the backbone of the organic chemical industry for many years to come, yet there is great opportunity for CO as an alternative feedstock at times when it is needed. The loosely defined body of chemistry and technology contained in these areas of development has become known as C 1 chemistry, embracing many C 1 building blocks such as CH , CO/H , CO, CH OH, CO and HCN; still emphasis 4 2 3 2 rests on carbon monoxide. Academic research laboratories, oil and chemical companies are in the vanguard of C 1 chemistry. The Japanese Ministry of International Trade and Industry is sponsoring a seven-year program of 14 major chemical companies in C 1 chemistry aimed at developing new technology for making basic chemicals from CO and H2 . It is likely that C 1 chemistry will develop slowly but persistently and the future holds great potential.

These two volumes collect thirty-eight selected papers from the scientific contributions presented at the Fourth European Workshop on Quantum Systems in Chemistry and Physics (QSCP-IV), held in Marly-le-Roi (France) in April 22-27, 1999. A total of one hundred and fifteen scientists attended the workshop, 99 from Europe and 16 from the rest of the world. They discussed the state of the art, new trends, and future evolution of the methods and applications. The workshop was held in the old town of Marly-le-Roi, which lies to the West of Paris between the historic centres of Saint-Germain-en-Laye and Versailles. Participants were housed at the National Youth Institute, where over sixty lectures were given by l- ding members of the scientific community; in addition, over sixty posters were presented in two very animated sessions. We are grateful to the oral speakers and to the poster p- senters for making the workshop such an stimulating experience. The social programme was also memorable - and not just for the closing banquet, which was held at the French Senate House.

Spectra for the Identification of Additives in Food Packaging
This new book on additives used in plastics for food contact, can be seen as a companion to the 1993 publication Spectra for the Identification of Monomers in Food Packaging [1, 2]. That earlier book presented information on monomeric substances listed in Directive 901128/EEC [3], which restricts the range of monomers and other starting substances that can be used for the production of plastics materials and articles intended for food contact applications. As a logical supplement to the collection of monomers and other starting substances, the preparation of a reference collection and a Handbook of analytical data of additives was undertaken with funding from The European Commission under the Standards Measurements and Testing programme. We then give a collection of spectra for the identification of 100 of the most important additives used in plastics packaging and coatings. Infra-red (FT-IR) and mass spectra (MS) are presented, as in the monomers book, but we have extended the scope to include proton nuclear magnetic resonance eH-NMR) spectra and gas-chromatographic (GC) data. Legal Framework The Commission of the European Communities provides in Synoptic Document N. 7 [4] a provisional list of additives used for the production of food contact plastics. This Synoptic Document anticipates a Directive on additives for food contact plastics. One hundred of the most important additives were selected from this provisional list after extensive consultation with researchers in the field and with representatives from European industry (Food Contact Additives Panel (FCA) sector group of the European Chemical Industry Council (CEFIC).

Spectroscopy of Biological Molecules: Modern Trends
The 1997 European Conference on Spectroscopy of Biological Molecules (ECSBM) is the seventh in a biennial series of conferences devoted to the applications of molecular spectroscopy to biological molecules and related systems. The interest of these conferences rests mainly on the relationship between the structure and physiological activity of biological molecules and related systems of which these molecular species form part. This volume ofECSBM contains articles prepared by the invited lecturers and those making poster presentations at the seventh ECSBM. The reader will find mainly applications of vibrational spectroscopy to protein structure and dynamics, biomembranes, molecular recognition, nucleic acids and other biomolecules and biological systems containing specific chromophors. Biomedical applications of vibrational spectroscopy are expanding rapidly. On the other hand, a significant number of the papers describe applications of other methods, such as NMR, circular dichroism, optical absorption and fluorescence, X-ray absorption and diffraction and other theoretical methods. One aim has been to achieve a well balanced, critically comparative review of recent progress in the field of biomolecular structure, bonding and dynamics based on applications of the above spectroscopic methods. A great part of the contributions included in this volume are devoted to biomedical and biotechnological applications and provide a broadly based account of recent applicationS in this field. The content of this book has been organized in sections corresponding mainly to the different types of biological molecules investigated. This book includes also another section related to theoretical methods where MO calculations of vibrational frequencies dominate clearly the topic.

An Introduction to Industrial Chemistry
to the Third Edition Following the success of the first two editions of this book in which the core subject matter has been retained, we have taken the opportunity to add substantial new material, including an additional chapter on that most important activity of the chemical industry, research and development. Topical items such as quality, safety and environmental issues also receive enhanced coverage. The team of authors for this edition comprises both those revising and updating their chapters and some new ones. The latter's different approach to the subject matter is reflected in the new titles: Organisational Structures - A Story of Evolution (chapter 5) and Environmental Impact of the Chemical Industry (chapter 9). The chapter on Energy retains its original title but different approach of the new authors is evident. We have updated statistics and tables wherever possible and expanded the index. We hope readers find the brief 'pen pictures' of authors to be interesting. It is worth stressing again that this book is designed to be used with its companion volume - The Chemical Industry, 2nd Edition, ed. Alan Heaton (referred to as Volume 2) - for a complete introduction to the chemical industry. Thanks are due to all contributors and to my wife Joy for typing my contributions.

Reactive Modifiers for Polymers
Chemical modification of polymers by reactive modifiers is no longer an academic curiosity but a commercial reality that has delivered a diverse range of speciality materials for niche markets: reactively grafted styrenic alloys, maleated polyolefins, super-tough nylons, silane modified and moisture-cured polyolefins, and thermoplastic elastomers, are but few exam ples of commercial successes. Although the approach of reactive modification of polymers has been largely achieved either in solution or in the solid state (through in situ reactions in polymer melts), it is the latter route that has attracted most attention in the last two decades owing to its flexibility and cost-effective ness. This route, referred to as reactive processing, focuses on the use of suitable reactive modifier(s) and the adoption of conventional polymer processing machinery, an extruder or a mixer, as a chemical reactor, to perform in situ targeted reactions for chemical modification of preformed polymers. This relatively simple, though scientifically highly challenging, approach to reactive modification offers unique opportunities in exploiting various reactive modifiers for the purpose of altering and transforming in a controlled manner the properties of preformed commercial polymers into new/speciality materials with tailor-made properties and custom-designed performance for target applications. Such an economically attractive route constitutes a radical diversion away from the traditional practices of manufacturing new polymers from monomers which involves massive in vestments in sophisticated technologies and chemical plants.

Viscous Flow Applications
The Boundary Element Method has now become a powerful tool of engineering analysis and is routinely applied for the solution of elastostatics and potential problems. More recently research has concentrated on solving a large variety of non-linear and time dependent applications and in particular the method has been developed for viscous fluid flow problems. This book presents the state of the art on the solution of viscous flow using boundary elements and discusses different current approaches which have been validated by numerical experiments. . Chapter 1 of the book presents a brief review of previous work on viscous flow simulation and in particular gives an up-to-date list of the most important BEM references in the field. Chapter 2 reviews the governing equations for general viscous flow, including compressibility. The authors present a compre hensive treatment of the different cases and their formulation in terms of boundary integral equations. This work has been the result of collaboration between Computational Mechanics Institute of Southampton and Massa chusetts Institute of Technology researchers. Chapter 3 describes the gen eralized formulation for unsteady viscous flow problems developed over many years at Georgia Institute of Technology. This formulation has been extensively applied to solve aer09ynamic problems.

Fundamentals of Polymer Engineering
W ALL ARE SURROUNDED by plastic materials and cannot imagine modem life and utilities without the synthetic polymers. And yet, how many of us can distinguish between polyethylene and PVC? After all, most people name any polymer as ''Nylon. /I Is there any distinction between polymers and plastics? This introductory textbook tries to answer these questions and many others. It endeavors to provide the basic information required in modem life about the best utilization of new materials in the plastics era; the chemical sources of synthetic polymers, and the processes in which small simple molecules are converted to giant macromolecules, namely, high polymers; and the understanding of the role of these unique structures, their behavior and performance, their mechanical and thermal properties, flow and deforma tion. As we are mainly interested in the final product, the processing of plastics, through shaping and forming, presents a significant challenge to polymer engineering. All this is broadly discussed, ending with modem issues like composites, ecology and future prediction, followed by up-to-date informa tion and data about old as well as novel high performance polymers. The text is particularly targeted towards senior students of science and engineering (chemical, material, mechanical and others) who may use it as the first window to the world of polymers. At the same time many profession als who are involved in the resin or plastics industry may prefer this approach without elaborate math or overloading.

Surface Modification of Polymeric Biomaterials
Applications of synthetic materials in medicine date back over 4000 year2. The Egyptians used linen as sutures. In the Roman Empire, gold was used in dentistry. Perhaps even earlier, ivory and bone may have been used in the body by practitioners of the healing arts. The historical origins of modem biomaterials science are also hard to precisely trace, but many of the ideas that define biomaterials as we know them today evolved in the late 1950s and early 1960s. Surface modification technology has played a prominent role in biomaterials science, and has paralleled the evolution of the modem field. In a symposium organized by the Artifical Heart Program of the NIH National Heart Institute and the Artificial Kidney program of the NIH National Institute of Arthritis and Metabolic Diseases, held in Atlantic City, New Jersey, in 1968, there were already a number of presentations on surface modification. Surface characterization at that time included scanning electron microscopy, ellipsometry, contact angle methods, and infrared internal reflection methods.

Molecular Interactions in Bioseparations
Rapid advances in molecular biology have accelerated the production of a great number of protein-based therapeutic agents. The major cost in producing these proteins appears to be associated with their purification from the complex mixture of the crude extract. A major challenge to the protein biochemist and the biochemical engineer is the development of rapid, efficient, and cost-effective purification systems. This volume presents state-of-the-art reviews of current methods used in the purifica tion of biological macromolecules that are based on molecular interactions. Thus, the major emphasis is placed on affinity-related techniques. Part I provides a general introduction to affinity chromatography and includes a chapter describing an interesting new technique called slalom chromatography for DNA fractionations. Affinity chromatography using molecules of biological origin as the affinity ligand is covered in Part II. Part III describes the use of a special class of biomolecules, antibodies, as affinity ligands. Affinity chromatography with biomimetic ligands is discussed in Part IV. Newer concepts and their applications in bioseparation are presented in Part V. Part VI covers affinity-related techniques such as affinity-based extracorporeal shunts, affinity electrophoresis, affinity precipitation, and affinity extraction. I would like to express my sincere thanks to all the authors, who are recognized experts in their respective fields, for their cooperation and contributions. I thank the editorial staff of Plenum Press for their professionalism, and Mary Phillips Born, Senior Editor, for her encouragement. The support of my family (Ping and Peilin) made it possible to complete editing this book. That T.

Here, the authors provide a unified concept for understanding multi-electron processes in electrochemical systems such as molten salts, ionic liquids, or ionic solutions. A major advantage of this concept is its independence of assumptions like one-step many-electron transfers or 'discrete' discharge of complex species. Therefore this monograph is a unique resource for basic electrochemical research but also for many important applications such as electrodeposition, electrorefining, or electrowinning of polyvalent metals from molten salts and other ionic media.

Epoxidations and Hydroperoxidations of , -Unsaturated Ketones: An Approach through Asymmetric Organocatalysis
Corinna Reisinger has developed a new organocatalytic asymmetric epoxidation of cyclic and acyclic , -unsaturated ketones. In this thesis, Corinna documents her methodology, using primary amine salts as catalysts, and hydrogen peroxide as an inexpensive and environmentally benign oxidant. She describes the unprecedented and powerful catalytic asymmetric hydro peroxi dation of , -enones, a process which produces optically active five-membered cyclic peroxyhemiketals in a single operation. She also proves the versatility and synthetic value of the cyclic peroxyhemiketals by converting them into highly enantioenriched acyclic and cyclic aldol products. Currently, these cyclic aldol products are inaccessible by any other synthetic means. Furthermore, cyclic peroxyhemiketals are precursors to optically active 1,2-dioxolanes which are of biological relevance. This work is a breakthrough in the field of asymmetric epoxidation chemistry and outlines the most efficient method in the literature for generating highly enantioselective cyclic epoxyketones known to date.

Detection of Non-Amplified Genomic DNA
This book offers an overview of state-of-the-art in non amplified DNA detection methods and provides chemists, biochemists, biotechnologists and material scientists with an introduction to these methods. In fact all these fields have dedicated resources to the problem of nucleic acid detection, each contributing with their own specific methods and concepts. This book will explain the basic principles of the different non amplified DNA detection methods available, highlighting their respective advantages and limitations. Non-amplified DNA detection can be achieved by adopting different techniques. Such techniques have allowed the commercialization of innovative platforms for DNA detection that are expected to break into the DNA diagnostics market. The enhanced sensitivity required for the detection of non amplified genomic DNA has prompted new strategies that can achieve ultrasensitivity by combining specific materials with specific detection tools. Advanced materials play multiple roles in ultrasensitive detection. Optical and electrochemical detection tools are among the most widely investigated to analyze non amplified nucleic acids. Biosensors based on piezoelectric crystal have been also used to detect unamplified genomic DNA. The main scientific topics related to DNA diagnostics are discussed by an outstanding set of authors with proven experience in this field.

Jonathan Scragg documents his work on a very promising material suitable for use in solar cells. Copper Zinc Tin Sulfide (CZTS) is a low cost, earth-abundant material suitable for large scale deployment in photovoltaics. Jonathan pioneered and optimized a low cost route to this material involving electroplating of the three metals concerned, followed by rapid thermal processing (RTP) in sulfur vapour. His beautifully detailed RTP studies - combined with techniques such as XRD, EDX and Raman - reveal the complex relationships between composition, processing and photovoltaic performance. This exceptional thesis contributes to the development of clean, sustainable and alternative sources of energy

Thermal Analysis of Polymeric Materials
Thermal analysis is an old technique. It has been neglected to some degree because developments of convenient methods of measurement have been slow and teaching of the understanding of the basics of thermal analysis is often wanting. Flexible, linear macromolecules, also not as accurately simply called polymers, make up the final, third, class of molecules which only was identified in 1920. Polymers have neverbeenfullyintegratedintothedisciplinesofscienceandengineering. Thisbook is designed to teach thermal analysis and the understanding of all materials, flexible macromolecules, as well as those of the small molecules and rigid macromolecules. The macroscopic tool of inquiry is thermal analysis, and the results are linked to microscopic molecular structure and motion. Measurements of heat and mass are the two roots of quantitative science. The macroscopic heat is connected to the microscopic atomic motion, while the macroscopic mass is linked to the microscopic atomic structure. The macroscopic unitsofmeasurementofheatandmassarethejouleandthegram,chosentobeeasily discernable by the human senses. The microscopic units of motion and structure are 12 10 the picosecond (10 seconds) and the angstrom (10 meters), chosen to fit the atomic scales. One notes a factor of 10,000 between the two atomic units when expressed in human units, second and gram-with one gram being equal to one cubic centimeter when considering water. Perhaps this is the reason for the much better understanding and greater interest in the structure of materials, being closer to human experience when compared to molecular motion.

Theory of Charge Transport in Carbon Electronic Materials
Mechanism of charge transport in organic solids has been an issue of intensive interests and debates for over 50 years, not only because of the applications in printing electronics, but also because of the great challenges in understanding the electronic processes in complex systems. With the fast developments of both electronic structure theory and the computational technology, the dream of predicting the charge mobility is now gradually becoming a reality. This volume describes recent progresses in Prof. Shuai's group in developing computational tools to assess the intrinsic carrier mobility for organic and carbon materials at the first-principles level. According to the electron-phonon coupling strength, the charge transport mechanism is classified into three different categories, namely, the localized hopping model, the extended band model, and the polaron model. For each of them, a corresponding theoretical approach is developed and implemented into typical examples.
