It is London in the 1890s. A young woman has just taken a dose of a tonic she’s been given in the belief that it will improve her complexion. About ten minutes pass and she starts to experience breathing difficulties. Another minute and she collapses. Mercifully, death arrives but the poison has not yet finished, for the process of rigor mortis has set in with unusual speed. Her body is frozen into a rigid and contorted mass. This is the horror of strychnine, the nastiest of poisons. Despite knowing all the dreadfulness of this poison, Dr Thomas Neill Cream, the Lambeth Poisoner, used it to kill several prostitutes. And who knows how many other victims experienced the horror of strychnine, for it was by no means an uncommon poison. Today, there may well be more poisons available to the individual than ever before, but there are also advances in medical examination and forensic analysis that increase the likelihood of the poisoner being caught. This book will examine poisons, both natural and man-made menaces, and cases based on a particular poison as well as information about how forensic analysis is conducted. Appealing to scientists and non-scientists alike, this enthralling book will entertain and educate and bring the reader up to date with how important chemical analysis is in crime detection.

The life and chemical sciences are in the midst of a period of rapid and revolutionary transformation that will undoubtedly bring societal benefits but also have potentially malign applications, notably in the development of chemical weapons. Such concerns are exacerbated by the unstable international security environment and the changing nature of armed conflict, which could fuel a desire by certain States to retain and use existing chemical weapons, as well as increase State interest in creating new weapons; whilst a broader range of actors may seek to employ diverse toxic chemicals as improvised weapons. Stark indications of the multi-faceted dangers we face can be seen in the chemical weapons attacks against civilians and combatants in Iraq and Syria, and also in more targeted chemical assassination operations in Malaysia and the UK. Using a multi-disciplinary approach, and drawing upon an international group of experts, this book analyses current and likely near-future advances in relevant science and technology, assessing the risks of their misuse. The book examines the current capabilities, limitations and failures of the existing international arms control and disarmament architecture – notably the Chemical Weapons Convention – in preventing the development and use of chemical weapons. Through the employment of a novel Holistic Arms Control methodology, the authors also look beyond the bounds of such treaties, to explore the full range of international law, international agreements and regulatory mechanisms potentially applicable to weapons employing toxic chemical agents, in order to develop recommendations for more effective routes to combat their proliferation and misuse. A particular emphasis is given to the roles that chemical and life scientists, health professionals and wider informed activist civil society can play in protecting the prohibition against poison and chemical weapons; and in working with States to build effective and responsive measures to ensure that the rapid scientific and technological advances are safeguarded from hostile use and are instead employed for the benefit of us all.

There is great interest in the preparation of synthetic receptor-based recognition units for cheap, robust, economic, and selective chemical sensors. Molecular imprinting provides the technology to prepare these synthetic units. There are still more and more syntheses of artificial molecular recognition constructs using analytes or their close structural analogues as templates for molecular imprinting. Stability of complexes of these constructs with the target analytes are often similar to those of biological receptors. Therefore, subsequent polymerization of these complexes results in molecularly imprinted polymers (MIPs) that have a selectivity close to that revealed by natural receptors. The book summarizes the latest developments and applications of molecular imprinting for selective chemical sensing with each chapter devoted to different analytical applications of molecularly imprinted polymers. Specific chapters include: designing of molecular cavities aided by computational modelling, application of molecularly imprinted polymers for separation as well as sensing of pharmaceuticals and nucleotides. The book is suitable for academics, postgraduates, and industrial researchers active in analytical chemistry, synthetic organic chemistry, molecular recognition, electrochemistry, and spectroscopy.

Metal ions play key roles in biology. Many are essential for catalysis, for electron transfer and for the fixation, sensing, and metabolism of gases. Others compete with those essential metal ions or have toxic or pharmacological effects. This book is structured around the periodic table and focuses on the control of metal ions in cells. It addresses the molecular aspects of binding, transport and storage that ensure balanced levels of the essential elements. Organisms have also developed mechanisms to deal with the non-essential metal ions. However, through new uses and manufacturing processes, organisms are increasingly exposed to changing levels of both essential and non-essential ions in new chemical forms. They may not have developed defenses against some of these forms (such as nanoparticles). Many diseases such as cancer, diabetes and neurodegeneration are associated with metal ion imbalance. There may be a deficiency of the essential metals, overload of either essential or non-essential metals or perturbation of the overall natural balance. This book is the first to comprehensively survey the molecular nature of the overall natural balance of metal ions in nutrition, toxicology and pharmacology. It is written as an introduction to research for students and researchers in academia and industry and begins with a chapter by Professor R J P Williams FRS.

Chemical Vapour Deposition (CVD) involves the deposition of thin solid films from chemical precursors in the vapour phase, and encompasses a variety of deposition techniques, including a range of thermal processes, plasma enhanced CVD (PECVD), photon- initiated CVD, and atomic layer deposition (ALD). The development of CVD technology owes a great deal to collaboration between different scientific disciplines such as chemistry, physics, materials science, engineering and microelectronics, and the publication of this book will promote and stimulate continued dialogue between scientists from these different research areas. The book is one of the most comprehensive overviews ever written on the key aspects of chemical vapour deposition processes and it is more comprehensive, technically detailed and up-to-date than other books on CVD. The contributing authors are all practising CVD technologists and are leading international experts in the field of CVD. It presents a logical and progressive overview of the various aspects of CVD processes. Basic concepts, such as the various types of CVD processes, the design of CVD reactors, reaction modelling and CVD precursor chemistry are covered in the first few chapters. Then follows a detailed description of the use of a variety CVD techniques to deposit a wide range of materials, including semiconductors, metals, metal oxides and nitrides, protective coatings and functional coatings on glass. Finally and uniquely, for a technical volume, industrial and commercial aspects of CVD are also discussed together with possible future trends, which is an unusual, but very important aspect of the book. The book has been written with CVD practitioners in mind, such as the chemist who wishes to learn more about CVD processes, or the CVD technologist who wishes to gain an increased knowledge of precursor chemistry. The volume will prove particularly useful to those who have recently entered the field, and it will also make a valuable contribution to chemistry and materials science lecture courses at undergraduate and postgraduate level.

The formation of disulfide bonds is probably the most influential modification of peptides and proteins. An elaborate set of cellular machinery exists to catalyze and guide this process. In recent years, significant developments have been made in both our understanding of the in vivo situation and the in vitro manipulation of disulfide bonds. This is the first monograph to provide a comprehensive overview of this exciting and rapidly developing area. It offers in-depth insights into the mechanisms of in vivo and in vitro oxidative folding of proteins as well as mono- and multiple-stranded peptides. Procedures applied for laboratory and industrial purposes are also discussed by top experts in the field. The book describes the enzymes involved in the correct oxidative folding of cysteine-containing proteins in prokaryotes and eukaryotes. It then goes on to discuss the mimicking of these enzymes for successful in vitro folding of proteins (including synthetic replicates) and to deal with important issues concerning cysteine-rich peptides. The ability of natural bioactive peptides to fold correctly, and in high yields, to form defined structural motifs using cysteine sequence patterns is still puzzling. With this in mind, synthetic procedures for establishing native cysteine frameworks are discussed using selected examples, such as the potential of selenocysteines. The biotechnological and pharmaceutical relevance of proteins, peptides, their variants and synthetic replicates is continuously increasing. Consequently, this book is invaluable for peptide and protein chemists involved in related research and production.

Chemical nomenclature is used to identify a chemical species by means of written or spoken words and enables a common language for communication amongst chemists. Nomenclature for chemical compounds additionally contains an explicit or implied relationship to the structure of the compound, in order that the reader or listener can deduce the structure from the name. This purpose requires a system of principles and rules, the application of which gives rise to a systematic nomenclature. Of course, a wide range of traditional names, semisystematic or trivial, are also in use for a core group of common compounds. Detailing the latest rules and international practice, this new volume can be considered a guide to the essential organic chemical nomenclature, commonly described as the "Blue Book". An invaluable source of information for organic chemists everywhere and the definitive guide for scientists working in academia or industry, for scientific publishers of books, journals and databases, and for organisations requiring internationally approved nomenclature in a legal or regulatory environment.

How can a plant as beautiful as the foxglove be so deadly and yet for more than a century be used to treat heart disease? The same is true of other naturally occurring molecules as will be revealed in these three books which examine poisons, both natural and man-made, and the crimes committed with them, not from the point of view of the murderers, their victims, or the detectives, but from the poison used. Molecules of Murder: Criminal Molecules and Classic Cases, More Molecules of Murder and Poisons and Poisonings: Death by Stealth throw new light on how these crimes were carried out, how the perpetrators were uncovered and brought to justice and information about how forensic analysis is conducted. Appealing to scientists and non-scientists alike, these enthralling books will entertain and educate and bring the reader up to date with how important chemical analysis is in crime detection.

Food safety is important and consumers have a right to expect that those who supply the food that they buy have taken every care to manufacture products that will do them no harm. Those with a responsibility for the regulation of the global food industry recognise this principle and legislate accordingly and the business of managing and regulating the safety of the food supply chain has come a long way in the last 25 years or so. Prompted by the emergence of new food safety hazards, such as the bacterial pathogens Listeria monocytogenes and E. coli O157, powerful new techniques for evaluating and managing the risks presented by these threats have been developed. For example, hazard analysis critical control point, or HACCP, has now become the food safety management system of choice worldwide. Although the food safety management tools are now widely available, they are still virtually useless unless they are supported by adequate and accurate information. HACCP does not work unless its practitioners have access to enough data and scientific knowledge to enable them to understand hazards and how to control them effectively. The Food Safety Hazard Guidebook is an attempt to address the problem of accessing the available information by distilling the key facts about a wide range of individual food safety hazards into a single text. The result is a guidebook, rather than an encyclopaedia, which acts as a portal for the immense and ever expanding body of scientific knowledge that exists for food safety. It is an easy-to-use information resource for anyone with a professional interest in the safety of the food supply. The book is easy to navigate and presents concise and carefully researched factual information on a wide range of biological and chemical hazards in a clear format that is designed to support risk analysis exercises and HACCP studies. It covers a broad range of established and emerging food safety hazards and includes details of authoritative sources of further information (many web-based) for those seeking to examine a topic in greater depth. The section on food allergens is a particularly valuable component of the book, the chapters on fish toxins are also useful and unusual in a book of this kind and bacterial pathogens are comprehensively covered. One of the most important features of the book is the wide scope of the content and the highly structured format designed to help the reader find information quickly. Other key benefits to the reader are: -The wide range of biological and chemical hazards covered in a single book -Written specifically with food industry professionals in mind -Easy to navigate and accessible for the non-expert -Clear and concise presentation of factual information presented in a format that lends itself to use in risk assessment exercises -Inclusion of references and web links to reliable sources of further information on each chapter -specifically designed for practical use by a professional readership.

The name "Allium" is said to come from the Greek word to avoid because of its offensive smell. The genus Allium includes more than 800 species of which only a few have been cultivated as foods. Many of the other members of this genus are popular with gardeners as easy to maintain perennials, although the smell of some members of the genus can be off-putting. The smell is a consequence of breakdown of sulfur-containing compounds which is a characteristic of this family of plants. Garlic, onions, leeks, chives and other members of the genus Allium occupy a unique position both as edible plants and herbal medicines, appreciated since the dawn of civilization. Alliums have been featured through the ages in literature, where they are both praised and reviled, as well as in architecture and the decorative arts. Garlic pills are top-selling herbal supplements while garlic-based products show considerable promise as environmentally friendly pesticides. The remarkable properties of the alliums can be understood based on the occurrence of a number of relatively simple sulfur-containing chemical compounds ingeniously packaged by nature in these plants. This unique book, with a foreword by 1990 Nobel Laureate E.J. Corey, outlines the extensive history and the fascinating past and present uses of these plants, sorting out fact from fiction based upon detailed scrutiny of historic documents as well as numerous laboratories studies. Readers will be entertained and educated as they learn about early cultivation of garlic and other alliums while being introduced to the chemistry and biochemistry. They will learn how alliums have been portrayed and used in literature, poetry, the arts and how alliums are featured in the world's oldest cookbook. Technical material is presented in a manner understandable to a general audience, particularly through the use of illustrations to simplify more difficult concepts and explain how experimental work is conducted. The book is heavily illustrated with examples of alliums in art, literature, agriculture, medicine and other areas and includes rare botanical drawings of many members of the genus Allium. Essential reading for anyone with a general interest in science, the book is written at a level accessible to experts and non-experts alike. It has sufficient additional detail and references to satisfy both those wanting to know more, as well as researchers in disciplines as diverse as archaeology, medicine, ecology, pharmacology, food and plant sciences, agriculture, and organic chemistry.
