As concerns with the efficient use of energy resources, and the minimization of environmental damage have come to the fore, there has been a renewed interest in the role that thermoelectric devices could play in generating electricity from waste heat, enabling cooling via refrigerators with no moving parts, and many other more specialized applications. The main problem in realizing this ambition is the rather low efficiency of such devices for general applications. This book deals with the proceedings of a workshop addressed that problems by reviewing the latest experimental and theoretical work on suitable materials for device applications and by exploring various strategies that might increase their efficiency. The proceedings cover a broad range of approaches, from the experimental work of fabricating new compounds through to theoretical work in characterizing and understanding their properties. The effects of strong electron correlation, disorder, the proximity to metal-insulator transitions, the properties of layered composite materials, and the introduction of voids or cages into the structure to reduce the lattice thermal conductivity are all explored as ways of enhancing the efficiency of their use in thermoelectric devices.

This book covers all aspects of marine chemistry such as the hydrographic and oceanographic characteristics of seawater, the toxicity of heavy metals in the marine environment, the quality of marinas and maritime areas, and the legal regime for protecting the marine environment from pollution. Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students and environmental managers alike.
The field of low-dimensional conductors has been very active for more than twenty years. It has grown continuously and both the inorganic and organic materials have remark able properties, such as charge and spin density waves and superconductivity. The discovery of superconductivity at high temperature in copper-based quasi two-dimensional conducting oxides nearly ten years ago has further enlarged the field and stimulated new research on inorganic conductors. It was obviously impossible to cover such a broad field in a ten day Institute and it seemed pertinent to concentrate on inorganic conductors, excluding the high Tc superconducting oxides. In this context, it was highly desirable to include both physics and chemistry in the same Institute in order to tighten or in some cases to establish links between physicists and chemists. This Advanced Study Institute is the continuation of a series of similar ones which have taken place every few years since 1974. 73 participants coming from 13 countries have taken part in this School at the beautiful site of the Centre de Physique des Houches in the Mont-Blanc mountain range. The scientific programme included more than forty lectures and seminars, two poster sessions and ten short talks. Several discussion sessions were organized for the evenings, one on New Materials, one on New Topics and one on the special problem of the Fermi and Luttinger liquids. The scientific activity was kept high from the beginning to the end of the Institute.

This unique book presents an integrated approach to the chemistry of art materials, exploring the many chemical processes involved. The Chemistry and Mechanism of Art Materials: Unsuspected Properties and Outcomes engages readers with historical vignettes detailing examples of unexpected outcomes due to materials used by known artists. The book discusses artists' materials focusing on relevant chemical mechanisms which underlie the synthesis and deterioration of inorganic pigments in paintings, the ageing of the binder in oil paintings, and sulfation of wall paintings as well as the toxicology of these pigments and solvents used by artists. Mechanisms illustrate the stepwise structural transformation of a variety of art materials. Based on the author's years of experience teaching college chemistry, the approach is descriptive and non-mathematical throughout. An introductory section includes a review of basic concepts and provides concise descriptions of analytical methods used in contemporary art conservation. Additional features include: Illustrations of chemical reactivity associated with art materials Includes a review of chemical bonding principles, redox and mechanism writing Covers analytical techniques used by art conservation scientists Accessible for readers with a limited science background Provides numerous references for readers seeking additional information
The elucidation of reaction mechanisms generally requires the carefully designed control of molecular symmetry to distinguish between the many possible reaction pathways. Making and Breaking Symmetry in Chemistry emphasises the crucial role played by symmetry in modern synthetic chemistry. After discussion of a number of famous classical experiments, the advances brought about by the introduction of new techniques, in particular NMR spectroscopy, are exemplified in numerous cases taken from the recent literature. Experimental verification of many of the predictions made in Woodward and Hoffmann's explication of the Conservation of Orbital Symmetry are described. Applications that involve the breaking of molecular symmetry to resolve these and other mechanistic problems in organic, inorganic and organometallic chemistry are presented in the first sections of the book, together with many examples of the detection of hitherto hidden rearrangement processes.Subsequently, under the aegis of making molecular symmetry, examples of the preparation of highly symmetrical molecules found in the organic, organometallic or inorganic domains are discussed. These include Platonic hydrocarbons or boranes, tetrahedranes, cubanes, prismanes, dodecahedrane, fullerene fragments such as corannulene, sumanene or semibuckminsterfullerene, and other systems of unusual geometries or bonding characteristics (Moebius strips, molecular brakes and gears, Chauvin's carbomers, Fitjer's rotanes, persubstituted rings, metal-metal multiple bonds, etc.). The text also contains vignettes of many of the scientists who made these major advances, as well as short sections that briefly summarise key features of important topics that underpin the more descriptive material. These include some aspects of chirality, NMR spectroscopy, and the use of isotopic substitution to break molecular symmetry. A brief appendix on point group symmetry and nomenclature is also helpfully provided.
This book aims to provide comprehensive and systematic introduction and summary of corrosion characteristics, mechanisms, and control methods of candidate alloys in sub- and supercritical water environment. First of all, corrosion types of candidate alloys and the effects of major alloying elements on corrosion resistance of potential alloys in sub- and supercritical water are compared and analyzed. At the same time, research status of candidate materials, and development and application trends of several corrosion-resistant alloys are summarized. Then, corrosion characteristics of Ni-Cr, Ni-Cr-Mo, Ni-Fe-Cr and Ni-Fe-Cr-Mo-Cu corrosion-resistant alloys, FeCrAl alloy, and Zircaloy are discussed in detail, including the corrosion rate, the structure and composition of oxide film, and the effects of various surface treatment processes, etc. More specifically, it also investigates corrosion behavior of Ni-based alloy, Fe-Ni-based, and stainless steels in supercritical water. The effects of aggressive species on the corrosion behavior of Ni-base alloys are also explored in supercritical water. Readers will further discover the total corrosion processes and mechanisms of typical candidate alloys in sub- and supercritical water environment. Finally, the work explores the corrosion control methods such as ceramic coatings and passivation processes in supercritical water oxidation and in subcritical water, respectively. Future challenges and development trends of corrosion research of candidate materials in sub- and supercritical water environments are covered at the end of this book. It offers valuable reference for theoretically guiding material selection and design and operating parameter optimization of key equipment in the sub- and supercritical water technologies. The book is written for senior undergraduates, graduate students, scholars, and researchers who are interested in corrosion behavior of candidate materials of supercritical water oxidation system, supercritical water gasification system, and nuclear reactor.
Electrochemical processes are long known but are becoming increasingly important again, due to modern applications, such as electro-mobility or energy storage. Thus, electrochemistry is not only a topic for chemists and physicists, but also for technical engineers. This book addresses all aspects of electrochemistry, which are important in these days: electrodes, corrosion, interphases, processes, energy storage, analytical methods, and sensors.
This volume on iron-sulfur proteins includes chapters that describe the initial discovery of iron-sulfur proteins in the 1960s to elucidation of the roles of iron sulfur clusters as prosthetic groups of enzymes, such as the citric acid cycle enzyme, aconitase, and numerous other proteins, ranging from nitrogenase to DNA repair proteins. The capacity of iron sulfur clusters to accept and delocalize single electrons is explained by basic chemical principles, which illustrate why iron sulfur proteins are uniquely suitable for electron transport and other activities. Techniques used for detection and stabilization of iron-sulfur clusters, including EPR and Mossbauer spectroscopies, are discussed because they are important for characterizing unrecognized and elusive iron sulfur proteins. Recent insights into how nitrogenase works have arisen from multiple advances, described here, including studies of high-resolution crystal structures.
This book provides fundamental knowledge of ceramics science and technology in a compact volume. Based on inorganic chemistry, it is intended as a reader for graduate students and young researchers beginning work in ceramics. The importance of the book is that it provides a scientific understanding of structure, properties, and processing from the chemical aspect, leading to creation of future ceramics. Ceramics have high hardness, strength, thermal and chemical stability, as well as various electromagnetic functions. To take full advantage of ceramics, their use has been advanced to engineering and electronic ceramics. Most ceramics have been fabricated by powder processing, and new technologies have also evolved such as CVD and sol-gel methods: new ceramics aimed at new functions of highly pure oxides and artificial nitrides, carbides, and borides; fine ceramics focused on precise control of composition and microstructure; and design of unique morphology, such as nanoparticles, nanofibers, nanosheets, mesoporous materials, and hybrids. Materials are composed of atoms and molecules. They are assembled into crystals and are amorphous, leading to 3-D micro/nano structures. In addition to the topics described above, this book shows the importance of chemistry for materials design at the nanometer scale, and that chemistry develops new fields of environment, energy, informatics, biomaterials, and other areas.

This book presents research in an evolving field, making it interesting to academics, postgraduate students, and experts within the field of oil and gas.
"Polymineral-Metasomatic Crystallogenesis" is dedicated to the foundations of polymineral crystallogenesis in solutions typically occurring in nature. Effects, laws, and mechanisms of a metasomatic crystal replacement, joint crystal growth of different phases, mixed crystal formation, and aggregate re-crystallization as well as oriented overgrowth (epitaxy and quasi-epitaxy) and crystal habit origin are considered experimentally. The behaviour of these processes in nature are discussed in addition to pseudomorphs, poikilitic crystals (and other replacement forms), features of rapakivi structure, fluorite morphology, and many more. The concept is a generalization of the classic theory on crystallogenesis which is complicated by phase interaction in polymineral systems. "Polymineral-Metasomatic Crystallogenesis" is designed for chemists, geologists, physicists, and postgraduates and advanced undergraduate students of these fields.
Chalcogen-nitrogen chemistry involves the study of compounds that exhibit a linkage between nitrogen and sulfur, selenium or tellurium atoms. Since the publication of A Guide to Chalcogen-Nitrogen Chemistry in 2005, the emphasis of investigations of chalcogen-nitrogen compounds has advanced from a focus on fundamental studies to the development of practical applications, as indicated by the title of this new edition. Pharmaceutical applications of organic sulfur-nitrogen compounds include drugs for the treatment of various diseases, as well as probes for locating tumour cells. From a materials perspective, carbon-containing chalcogen-nitrogen heterocycles have applications in everyday devices such as LEDs and solar cells. A new technology based on binary sulfur nitrides is being used for fingerprint detection in forensic science. As a result, this book includes seven new chapters and updates the others with extensive literature coverage of developments since 2005 while retaining earlier seminal results. This comprehensive text is essential for anyone working in the field, and the four introductory chapters emphasise general concepts that will be helpful to the non-specialist. The treatment is unique in providing a comparison of sulfur, selenium and tellurium compounds. Each chapter is designed to be self-contained, and there are extensive cross-references between chapters.

Developments in the title field have been greatly motivated by the studies of transactinoid elements; selected experiments and their results are presented for visualization. Primarily, the book is about the physico-chemical basis of the experimental methods and techniques which are or can be used for compounds of all heavy metals; about evaluation of the desorption energies from the original gas-solid chromatography data; and about concepts and approaches which allow to estimate bulk properties of the compounds even from experiments with a few short-lived atoms. The book attempts for the first time critical discussion of the state of art from a coherent point of view to help better understanding. It was written both for the newcomers to the field and experts, its goal is also to stimulate wider use of the advantageous gas phase techniques for common elements.
This thesis shares new findings on the interfacial mechanics of graphene-based materials interacting with rigid/soft substrate and with one another. It presents an experimental platform including various loading modes that allow nanoscale deformation of atomically thin films, and a combination of atomic force microscopy (AFM) and Raman spectroscopy that allows both displacement and strain to be precisely measured at microscale. The thesis argues that the rich interfacial behaviors of graphene are dominated by weak van der Waals force, which can be effectively modulated using chemical strategies. The continuum theories are demonstrated to be applicable to nano-mechanics and can be used to predict key parameters such as shear/friction and adhesion. Addressing key interfacial mechanics issues, the findings in thesis not only offer quantitative insights in the novel features of friction and adhesion to be found only at nanoscale, but will also facilitate the deterministic design of high-performance graphene-based nanodevices and nanocomposites.
The series Structure and Bonding publishes critical reviews on
topics of research concerned with chemical structure and bonding.
The scope of the series spans the entire Periodic Table and
addresses structure and bonding issues associated with all of the
elements. It also focuses attention on new and developing areas of
modern structural and theoretical chemistry such as nanostructures,
molecular electronics, designed molecular solids, surfaces, metal
clusters and supramolecular structures. Physical and spectroscopic
techniques used to determine, examine and model structures fall
within the purview of Structure and Bonding to the extent that the
focus is on the scientific results obtained and not on specialist
information concerning the techniques themselves. Issues associated
with the development of bonding models and generalizations that
illuminate the reactivity pathways and rates of chemical processes
are also relevant.The individual volumes in the series are
thematic. The goal of each volume is to give the reader, whether at
a university or in industry, a comprehensive overview of an area
where new insights are emerging that are of interest to a larger
scientific audience. Thus each review within the volume critically
surveys one aspect of that topic and places it within the context
of the volume as a whole. The most significant developments of the
last 5 to 10 years should be presented using selected examples to
illustrate the principles discussed. A description of the physical
basis of the experimental techniques that have been used to provide
the primary data may also be appropriate, if it has not been
covered in detail elsewhere. The coverage need not be exhaustive in
data, but should rather be conceptual, concentrating on the new
principles being developed that will allow the reader, who is not a
specialist in the area covered, to understand the data presented.
Discussion of possible future research directions in the area is
welcomed. Review articles for the individual volumes are invited by
the volume editors.
This book explores how structure impacts the dynamics of organic molecules in an extensive and impressive range of femtosecond time-resolved experiments that are combined with state-of-the-art theoretical approaches. It explores an area of molecular dynamics that remains largely uncharted and provides an extraordinary overview, along with novel insights into the concept of the dynamophore - the functional group of ultrafast science. Divided into four parts, this book outlines both experimental and computational studies on the VUV photoinduced dynamics of four cyclic ketones and one linear ketone, the ring-opening and dissociative dynamics of cyclopropane, and the potential ultrafast intersystem crossing in three methylated benzene derivatives. Model systems for the disulfide bond and the peptide bond, both of which are related to the structure of proteins, are also investigated. This highly informative and carefully presented book offers a wealth of scientific insights for all scholars with an interest in molecular dynamics.
This book covers all important nomenclature, theories of bonding and stereochemistry of coordination complexes.

The complexities of Molecular Orbital theory have been explained in a very simple and easy manner. It also deals with transition and inner transition metals. Conceptually, all transition and inner transition elements form complexes which have definite geometry and show interesting properties. General and specific methods of preparation, physical and chemical properties of each element has been discussed at length. Group wise study of elements in d-block series have been explained. Important compounds, complexes and organometallic compounds of metals in different oxidation states have been given explicitly. Note: T&F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.
Intended for students of intermediate organic chemistry, this text shows how to write a reasonable mechanism for an organic chemical transformation. The discussion is organized by types of mechanisms and the conditions under which the reaction is executed, rather than by the overall reaction as is the case in most textbooks. Each chapter discusses common mechanistic pathways and suggests practical tips for drawing them. Worked problems are included in the discussion of each mechanism, and "common error alerts" are scattered throughout the text to warn readers about pitfalls and misconceptions that bedevil students. Each chapter is capped by a large problem set.
Edited by a team of highly respected researchers combining their expertise in chemistry, physics, and medicine, this book focuses on the use of ruthenium-containing complexes in artificial photosynthesis and medicine. Following a brief introduction to the basic coordination chemistry of ruthenium-containing complexes and their synthesis, as well as their photophysical and photochemical properties, the authors discuss in detail the major concepts of artificial photosynthesis and mechanisms of hydrogen production and water oxidation with ruthenium. The second part of the text covers biological properties and important medical applications of ruthenium-containing complexes as therapeutic agents or in diagnostic imaging. Aimed at stimulating research in this active field, this is an invaluable information source for researchers in academia, health research institutes, and governmental departments working in the field of organometallic chemistry, green and sustainable chemistry as well as medicine/drug discovery, while equally serving as a useful reference also for scientists in industry.
