At the end, three relevant topics are included as appendices for updating students and faculty members.
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."

The second edition of Metal Ions in Biochemistry deals with the multidisciplinary subject of bio-inorganic chemistry, encompassing the disciplines of inorganic chemistry, biochemistry and medicine. The book deals with the role of metal ions in biochemistry, emphasising that biochemistry is mainly the chemistry of metal-biochemical complexes. Hence, the book starts with the structures of biochemicals and the identification of their metal binding sites. Thermodynamic and kinetic properties of the complexes are explained from the point of view of the nature of metal-ligand bonds. Various catalytic and structural roles of metal ions in biochemicals are discussed in detail. Features The role of Na+ and K+ in brain chemistry. The role of zinc insulin in glucose metabolism and its enhancement by vanadium and chromium compounds. Discussion of the role of zinc signals, zinc fingers and cascade effect in biochemistry. Haemoglobin synthesis and the role of vitamin B12 in it. The role of lanthanides in biochemical systems. A detailed discussion of the role of non-metals in biochemistry, a topic missing in most of the books on bio-inorganic chemistry. The study of bio-inorganic chemistry makes biochemists rethink the mechanistic pathways of biochemical reactions mediated by metal ions. There is a realisation of the role of metal complexes and inorganic ions as therapeutics such as iron in leukaemia, thalassemia and sickle cell anaemia, iodine in hypothyroidism and zinc, vanadium and chromium in glucose metabolism. The most recent realisation is of the use of zinc in the prevention and treatment of COVID-19.
With the development of science and technology,more and more complex materials such as porous materials, ion liquid, liquid crystals, thin ?lms and colloids etc. are being developed in laboratories. However, it is dif?cult to prepare these advanced materials and use them on a large scale without some experience. Therefore, mo- cular thermodynamics, a method that laid emphasis on correlating and interpreting the thermodynamic properties of a variety of ?uids in the past, has been recently employed to study the equilibrium properties of complex materials and establish thermodynamic models to analyse the evolution process of their components, - crostructures and functions during the preparation process. In this volume, some important progress in this ?eld, from fundamental aspects to practical applications, is reviewed. In the ?rst chapter of this volume, Prof. Jianzhong Wu presents the application of Density Functional theory (DFT) for the study of the structure and thermodynamic properties of both bulk and inhomogeneous ?uids. This chapter presents a tut- ial overview of the basic concepts of DFT for classical systems, the mathematical relations linking the microstructure and correlation functions to measurable th- modynamic quantities, and the connections of DFT with conventional liquid-state theories. While for pedagogythe discussion is limited to one-componentsimple - ids, similar ideas and concepts are directly applicable to mixtures and polymeric systems of practical concern. This chapter also covers a few theoretical approaches to formulate the thermodynamic functional.
SELECTED AS ONE OF THE BEST BOOKS OF 2018 BY THE DAILY MAIL 'A hugely entertaining tour of the periodic table and the 118 elements that are the basic building blocks of everything' Daily Mail In 2016, with the addition of four final elements - nihonium, moscovium, tennessine and oganesson - to make a total of 118 elements, the periodic table was finally complete, rendering any pre-existing books on the subject obsolete. Tim James, the science YouTuber and secondary-school teacher we all wish we'd had, provides an accessible and wonderfully entertaining 'biography of chemistry' that uses stories to explain the positions and patterns of elements in the periodic table. Many popular science titles tend to tell the history of scientific developments, leaving the actual science largely unexplained; James, however, makes use of stories to explain the principles of chemistry within the table, showing its relevance to everyday life. Quirkily illustrated and filled with humour, this is the perfect book for students wanting to learn chemistry or for parents wanting to help, but it is also for anyone who wants to understand how our world works at a fundamental level. The periodic table, that abstract and seemingly jumbled graphic, holds (nearly) all the answers. As James puts it, elements are 'the building blocks nature uses for cosmic cookery: the purest substances making up everything from beetroot to bicycles.' Whether you're studying the periodic table for the first time or are simply interested in the fundamental building blocks of the universe - from the core of the sun to the networks in our brains - Elemental is the perfect guide.

Finalist for the Los Angeles Times Book Prize for Science and Technology "Very well-written and rewarding … an excellent account of the story." —Nature Ten years ago, the discovery of buckminsterfullerene, a previously unknown form of carbon, stunned the scientific community, as much for the discovery itself as for the manner in which it came about. In the words of author Hugh Aldersey-Williams. it was an example of "classic bootleg science. The work was done on the back of other, funded projects, and when time would allow. Yet its commercial implications are probably immense." Now, in a lively account, The Most Beautiful Molecule chronicles the events leading up to this momentous discovery and the ongoing, often frenzied aftermath. Hugh Aldersey-Williams leads us on a thrilling expedition to the very forefront of modern chemistry research.

This book provides a comprehensive review of the current state of the art in silicon compounds for thermoelectric applications. Silicides are materials with good initial thermoelectric properties, which can be enhanced through tuning of their micro- and macrostructure. These compounds present various conduction mechanisms and complex band structures. Moreover, some are isotropic, and others anisotropic, which is highly beneficial for device tailoring. Silicides are a particularly attractive material for sensors, thermoelectric generators, and other applications because they are environmentally friendly, abundant, and low cost. This concise volume covers fundamentals and applications for an audience of materials scientists, chemists, solid-state physicists, and engineers.
Originally published in 1919, this book was written in an attempt to summarise some of the most important discoveries in inorganic chemistry during the previous fifteen years and to relate them to the teaching of the subject in schools. This book will be of value to anyone with an interest in inorganic chemistry, the history of education and the history of science.
This brief introduces the classification and mechanism of density gradient ultracentrifugation (DGUC) method with rich examples showing the versatility of such an efficient separation technique. It also gives a strict mathematical description and a computational optimization model to predict the best separation parameters for a given colloidal system. The concept of "Lab in a tube" is proposed in the last chapter, which allows the size-property relationship investigation, synthetic optimization and reaction/assembly mechanism exploration etc.
Historically, technological developments that have made use of the acidity/basicity of solids have often preceded an understanding of the phenomena involved. This, of course, is very expensive, and a far less efficient process than research based on a fundamental understanding of the science. For the last 50 years, therefore, a vast amount of research has been devoted to the subject: the rewards, in terms of technological advantage, were seen to be high. In the last few years, however, significant advances in the field have been achieved, in terms of our theoretical understanding, in instrumentation that allows research to be conducted "in situ" and under conditions appropriate to industrial processes, and in the realization that a closer coupling between science and technology can improve our quest. It is against such a background that "Acidity and Basicity of Solids" presents work in the field. This text should be suitable for specialized workers in the field and university teachers of introductory as well as graduate courses. The more general reader may find the reviews interesting.
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. Readership: research scientists at universities or in industry, graduate students Special offer for all customers who have a standing order to the print version of Structure and Bonding, we offer free access to the electronic volumes of the Series published in the current year via SpringerLink.
Troy Townsend's thesis explores the structure, energetics and activity of three inorganic nanocrystal photocatalysts. The goal of this work is to investigate the potential of metal oxide nanocrystals for application in photocatalytic water splitting, which could one day provide us with clean hydrogen fuel derived from water and solar energy. Specifically, Townsend's work addresses the effects of co-catalyst addition to niobium oxide nanotubes for photocatalytic water reduction to hydrogen, and the first use of iron oxide 'rust' in nanocrystal suspensions for oxygen production. In addition, Townsend studies a nickel/oxide-strontium titanate nanocomposite which can be described as one of only four nanoscale water splitting photocatalysts. He also examines the charge transport for this system. Overall, this collection of studies brings relevance to the design of inorganic nanomaterials for photocatalytic water splitting while introducing new directions for solar energy conversion.
The contributed volume addresses a wide range of topics including, but not limited to, biotechnology, synthetic chemistry, polymer chemistry and materials chemistry. The book will serve as a specialized review of the field of biologically inspired silicon-based structures. Researchers studying biologically inspired silicon materials chemistry will find this volume invaluable.
