The authors discuss chemical aspects of carbon nanostructures, their synthesis, functionalization and design strategies for defi ned applications. Recent advances in carbon nanomembranes, molecule-assisted ultrasound-induced liquid-phase exfoliation of graphene, and solution synthesis of graphene nanoribbons and biological application of nanodiamonds are highlighted topics. This book provides an excellent reference on the chemistry of carbon nanostructures for Chemists, Materials Scientists, Condensed-matter Physicists, Surface Scientists, and Engineers.

The contributions to this volume focus on selected chemical aspects of rare-earth materials. The topics covered range from a basic treatment of crystalline electric-field effects and chemical interactions in organic solvents, to separation processes, electrochemical beaviors which impact corrosion, oxidation resistance, chemical energy storage and sensor technology, and to analytical procedures.

Underlying the most subtle chemical and optical properties of these elements and their compounds in the condensed state are the crystal field effects. This phenomenon in non-metallic compounds is discussed in chapter six. The volume opens with a review of important new solvent extraction procedures as well as emerging alternative separation processes such as photochemical separation, precipitation stripping and supercritical extraction. Scientific and industrial procedures are illustrated. In a further chapter eight major analytical techniques of obtaining accurate trace analysis are examined, tabulated and assessed. The most effective procedures of each are also reviewed. Chapter two considers a wide variety of methods using rare-earth solutions and slats to modify advantageously the costly deterioration of metals and alloys. This topic is expanded in the following chapter, paying particular attention to protection against high-temperature oxidation, sulfidization and hot-salt corrosion. The following two chapters are concerned with the versatility of the rare earths in addressing current technical problems such the use of rare-earth intermetallics, principally LaNi3-based materials, to provide the skyrocketing need for environmetally friendly, usually portable, battery power. The final chapter is a review of the solvation, interaction and coordination of rare-earth salts in a variety of organic solvents including dimethylacetamide, dimethylsulfoxide, various alcohols, acetonitrile and propylenecarbonate under strict anhydrous conditions. A contrast of these interactions with those in which water is present with organic solvents is also made.

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 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.

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 is an an absolutely wonderful book that is full of gems about the elements and the periodic table ... All in all, the book is highly recommended to philosophers of chemistry. As philosophers we have a natural tendency to concentrate on generalities and not to get too involved in the specifics and the details. Above all else, this new book reminds us that such an approach needs to be tempered by a detailed knowledge of the exceptions and features that go against the simplified generalities which we so cherish.' [Read Full Review]Eric ScerriFoundations of Chemistry'Many questions are dealt with in a clearly written way in this stimulating and innovative book. The reader will quickly become interested in the subject and will be taken on tour through this Periodic Table in a very readable way, both for students and teachers ... The number of illustrations is good, and clear. This book is indeed unique and quite thought-provoking ... This book is highly recommended for students, teachers, researchers and not only chemists! Geologists, biochemist and also physicists will find it very interesting to read.' [Read Full Review]Chemistry InternationalThat fossilized chart on every classroom wall - isn't that The Periodic Table? Isn't that what Mendeleev devised about a century ago? No and No. There are many ways of organizing the chemical elements, some of which are thought-provoking, and which reveal philosophical challenges. Where does hydrogen 'belong'? Can an element occupy more than one location on the chart? Which are the Group 3 elements? Is aluminum in the wrong place? Why is silver(I) like thallium(I)? Why is vanadium like molybdenum? Why does gold form an auride ion like a halide ion? Does an atom 'know' if it is a non-metal or metal? Which elements are the 'metalloids'? Which are the triels? So many questions! In this stimulating and innovative book, the Reader will be taken on a voyage from the past to the present to the future of the Periodic Table. This book is unique. This book is readable. This book is thought-provoking. It is a multi-dimensional examination of patterns and trends among the chemical elements. Every reader will discover something about the chemical elements which will provoke thought and a new appreciation as to how the elements relate together.

This book summarizes some recent developments in the area of high-energy high-density (HEDM) materials. Rather than being comprehensive in scope, emphasis is given to structural and bonding features of highly energetic - terials with possible applications as high explosives (secondary explosives) or propellants. In this book we do not focus on primary explosives (e.g. lead azidereplacements)sincebyde?nitiontheexplosiveperformance(detonation velocity and detonation pressure) of such materials - although very sensitive -are much less energetic than secondary (high) explosives. Modern HEDMs derive most of their energy (i) from oxidation of the c- bon backbone, as in traditional energetic materials, (ii) from ring or cage strain, or (iii) from their very high positive heat of formation. Examples of the?rstclassare traditionalexplosives, suchasTNT, RDXand HMX.Modern nitro-compounds, such as CL-20 or the recently reported hepta- and octa- trocubanes, belong to the second group of explosives and possess very high densities and enhance the energies utilizing substantial cage strain. Members of the third class of compounds are high-nitrogen compounds (up to 85% - trogencontent), such as aminotetrazole and nitrotetrazolederivatives, which show the desired remarkable insensitivity to electrostatic discharge, friction and impact, while having very high positive heats of formation and therefore very high explosive powers. The synthesis of energetic, non-nuclear materials for military application has been a long-term goal in various academic and military research groups worldwide. Some of the current challenges that face HEDMscientists are: Demandforenvironmentallycompatibleandtoxicologicallyacceptable- plosives and propellants. Examples are replacements for TNT, RDX and HMXsince nitro-explosivesper se, aswellastheir environmental transf- mation products, are toxic."

"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.

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.

A dangerous byproduct of industrial progress is often an increase of pollutants discharged into the environment. These pollutants are often harmful to plants and animals, including humans. They also damage buildings and architectural and cultural monuments. This handbook describes many of the important physico-chemical properties of inorganic and organic substances found in industrial wastes and describes their toxic effects on humans.

Chemists increasingly apply electrochemical methods to the investigation of their systems, in particular towards a better understanding of molecular properties, the exploration of chemical reactions involving electron-transfer (ET), the initiation of further reactions by ET, the kinetic measurements, and the establishment of the reaction mechanisms, as well as the synthesis (electrosynthesis) of desired products. Trends in Molecular Electrochemistry presents recent research on procedures in molecular electroactivation and electrocatalysis, bioelectrochemistry, spectroelectrochemistry, and unconventional electrochemistry. The book highlights the state-of-the-art in the application of electrochemistry by taking an interdisciplinary approach to the study of both static and dynamic molecular properties of coordination compounds as well as inorganic, bioinorganic, and organometallic complexes, supramolecular systems, and metalloenzymes. The principles and approaches are often also valid for organic systems, which are illustrated in various contexts.

They cover methods using activating agents such as alkaline hydroxides as well as endo- and exotemplates made from zeolites, silica, and colloidal crystals. The third chapter examines techniques for characterizing carbon surface chemistry, including electrochemical, spectroscopic, and chromatographic methods. The fourth and final chapter compares the virtues of exfoliated graphite, carbonized fir fibers, carbon fiber felt, and charcoals in solving oil spill problems, a matter of increasing environmental concern. Emphasizing key experimental results, practical aspects, and cutting-edge applications in every chapter, Volume 30 is a vital resource for those developing new technologies such as drug delivery, adsorbents for oil/chemical spills, materials processing, high-performance nanocarbons, and energy storage and conversion devices, including lithium ion batteries, supercapacitors, and fuel cells.

High surface area, a microporous structure, and a high degree of surface reactivity make activated carbons versatile adsorbents, particularly effective in the adsorption of organic and inorganic pollutants from aqueous solutions. Activated Carbon Adsorption introduces the parameters and mechanisms involved in the activated carbon adsorption of organic and inorganic compounds. This text brings together the most significant research on surface structure and processes, adsorption theories and isotherm equations, and applications from the latest literature on carbon adsorption. The book clearly explains the surface-related interactions of activated carbons, their energetics, and the applicability of adsorption isotherm equations and their deviation from adsorption data. It then explores numerous applications in a wide range of areas, such as nuclear technology, vacuum technology, food technology, pharmaceuticals and medicine, gas storage, oil refining, and environmental remediation. Topics include: oils and fats, molecular sieves, refining of liquid fuels, pesticides, dyes, drugs, and toxins. Three chapters are dedicated to environmental applications, including the adsorption of halogenated organic compounds and the removal of hazardous gases and vapors, organo-sulphur compounds, and other inorganic compounds from wastewater and groundwater. Activated Carbon Adsorption presents a complete survey of the growing number of state-of-the-art applications supported by a compilation of the latest perspectives in research concerning carbon surfaces and their adsorption processes from aqueous solutions. Its unified approach promotes further research towards improving and developing newer activated carbon adsorbents and processes for the efficient removal of pollutants from drinking water and industrial effluents.

CHEMISTRY STUDENT GUIDES. GUIDED BY STUDENTS Why did the drug thalidomide cause birth defects? What is the chemical difference between sucrose and lactose in your food? Stereochemistry holds the answer and is essential to the understanding of the chemistry of life. Stereochemistry is an important concept that often causes confusion amongst students when they learn it for the first time. Unlike most other areas of chemistry, it requires the chemist to visualise molecules in 3D, which can be difficult. In this book we deal with tricky concepts like conformation and configuration, how to represent them accurately and how to use the correct terms to describe them in both organic and inorganic chemistry. We involved students in the writing process to ensure we deal with areas that you find difficult, in an understandable language. With problems designed to focus on common errors and misconceptions, real life examples, and practical hands-on exercises coupled with visualisation tips, our intention is to give you the tools to become confident in stererochemistry. Complementing mainstream organic textbooks, or self-study, this book is for anyone who has struggled with describing alkenes as E or Z, assigning R and S absolute configurations, drawing Newman projections or chair representations of cyclohexanes, axial chirality, understanding the stereochemistry of octahedral metal complexes and indeed explaining complexities observed in NMR spectra. Chemistry Student Guides are written with current students involved at every stage, guiding the books towards the most challenging aspects of the topic. Student co-authors for Introduction to Stereochemistry are Caroline Akamune, Michael Lloyd and Matthew Taylor.

For the first time the discipline of modern inorganic chemistry has been systematized according to a plan constructed by a council of editorial advisors and consultants, among them three Nobel laureates (E.O. Fischer, H. Taube and G. Wilkinson).
Rather than producing a collection of unrelated review articles, the series creates a framework which reflects the creative potential of this scientific discipline. Thus, it stimulates future development by identifying areas which are fruitful for further research.
The work is indexed in a unique way by a structured system which maximizes its usefulness to the reader. It augments the organization of the work by providing additional routes of access for specific compounds, reactions and other topics.

The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. 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 are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

The use of silver as an antibacterial agent has been known for thousands of years. This effect can be amplified by simply reducing the size of silver particles to the nanoscale, with an added advantage of reduction in cost and toxicity. Application of silver nanoparticles to textiles can bring considerable advantages, especially for materials that cannot be washed daily or medical support materials. This book describes a novel synthesis method that the author calls "in situ," in which these nanoparticles are obtained directly on materials. The method is simple and easy to apply and can also be considered green because the reducing agent involved is ascorbic acid, commonly known as vitamin C. It neither requires special modifications in the industrial equipment nor special pressure or temperature conditions. It can be used to grow other metals or metal oxides on a material. The book showcases studies carried out on silver nanoparticles by the author over several years, not only in terms of the synthesis but also the morphological characterization of the substrate to which they were applied. It exhibits SEM images displaying the homogeneity of the silver coating, highlighting that sometimes the simplest way is the best way.
