Information technology is essential to our daily life, and the limitations of silicone based memory systems mean a growing amount of research is focussed on finding an inexpensive alternative to meet our needs and allow the continued development of the industry. Inorganic silicone based technology is increasingly costly and complex and is physically limited by the problems of scaling down. Organic electrical memory devices are comparatively low cost, offer flexibility in terms of chemical structure, are compatible with flexible substrates and allow easy processing. For these reasons polymeric memory nanoscale materials are considered by many to be a potential substitute for conventional semiconductor memory systems. This edited book focusses solely on organic memory devices, providing a full background and overview of the area before bringing the reader up to date with the current and ongoing research in this area. The broad appeal of this book will be applicable to a wide range of researchers and those working in industry, in particular those working in materials, electrical and chemical engineering.

Several books and many papers have been published during the last decade on the design and the use of new nanomaterials in medicine and technology, which describe major concepts of nanotechnology. Meanwhile, a new promising type of nanomaterials-bacteriophages-emerged recently as a result of the evolution of phage display technique. Bacteriophages have a unique feature - completely the opposite of other nanomaterials -their structure and function are encrypted in their genomic DNA, which can be intentionally modified or even rewritten using routine genetic engineering techniques. In particular, a paradigm of landscape phage with multivalently displayed foreign peptides evolved, which allows constructing phage with unique surface architectures and emerged properties. Recently, phage, as a new kind of nanomaterials attracted the attention of specialists working in peripheral, and even very diverse areas from genetics and molecular biology, such as pharmaceutical science, material science, microelectronics, biosensors, detection, environmental sciences, etc. Penetration of the phage technology into these new disciplines required the development of a new instructive concept, which resulted in this publication. This comprehensive book, of value to researchers as well as scientists, introduces readers into this hot new area of phage nanobiotechnology. It summarises the existing data on the phage nanomaterials and discusses their use in different areas of medicine, science and technology. With contributions by top level experts and pioneers in phage display, the major goal of this book is to bring the phage display technique closer to specialists in these diverse areas of medicine, science and technology, where phage-derived nanomaterials can be most beneficial.

Fatty alcohols occur naturally in most organisms and can also be used in consumer products including detergents and cosmetics and all of these materials make their way to the sea eventually. These long chain alcohols can be used as biomarkers due to their distinctive source allocations although they have differential degradation rates across the range of chain lengths. Concern has been raised about their inputs from anthropogenic uses and this book seeks to set out the natural and industrial synthetic pathways, sources, signatures, concentrations in the environment, toxicity and eco-toxicity before summarising their impact. Their large scale synthesis for industrial uses puts them in the 'High Production Volume' category and they will need to be addressed in REACH (Registration, Evaluation and Authorization of Chemicals) - a new European legislation for chemicals and substances. There is no other book that considers the fatty alcohols from their production, environmental behaviour and potential toxicity viewpoint. The book, which is also well illustrated, presents for the first time environmental data from many locations around the world and discusses the anthropogenic contributions to these places.

Within months of the start of the First World War, Germany began to run out of the raw materials it needed to make explosives. As Germany faced imminent defeat, chemists such as Fritz Haber and Carl Bosch came to the rescue with Nobel Prize winning discoveries that overcame the shortages and enabled the country to continue in the war. Similarly, Britain could not have sustained its war effort for four years had it not been for chemists like Chaim Weizmann who was later to become the first president of the State of Israel. Michael Freemantle tells the stories of these and many other chemists and explains how their work underpinned and shaped what became known as The Chemists’ War. He reveals: • how chemistry contributed to the care of the sick and wounded and to the health and safety of troops; • how coal not only powered the war but was also an important source of the chemicals needed for the manufacture of explosives, dyes, medicines and antiseptics; • how Britain’s production of propellants relied on the slaughter of tens of thousands of whales; • how a precious metal played a critical role in the war; • how poisonous chemicals were used as weapons of mass destruction for the first time in the history of warfare and how chemists developed gas masks for protection against these weapons; • how the British naval blockade of Germany imperilled agricultural production in the United States. The book will appeal to the general reader as well as the many scientists and historians interested in the Great War.

The Mesoamerican population who lived near the indigenous cultivation sites of the "Chocolate Tree" (Theobromo cacao) had a multitude of documented applications of chocolate as medicine, ranging from alleviating fatigue to preventing heart ailments to treating snakebite. Until recently, these applications have received little sound scientific scrutiny. Rather, it has been the reputed health claims stemming from Europe and the United States which have attracted considerable biomedical attention. This book, for the first time, describes the centuries-long quest to uncover chocolate's potential health benefits. The authors explore variations in the types of evidence used to support chocolate's use as medicine as well as note the ongoing tension over categorizing chocolate as food or medicine, and more recently, as functional food or nutraceutical. The authors, Wilson an historian of science and medicine, and Hurst an analytical chemist in the chocolate industry, bring their collective insights to bear upon the development of ideas and practices surrounding the use of chocolate as medicine. Chocolate's use in this manner is explored first among the Mesoamerican peoples, then as it is transported to Europe, and back into Colonial North America. The authors then focus upon more recent bioscience experimental undertakings which have been aimed to ascertain both long-standing and novel suggestions as to chocolate's efficacy as a medicinal and a nutritional substance. Chocolate/s reputation as the most craved food boosts this book's appeal to food and biomedical scientists, cacao researchers, ethnobotanists, historians, folklorists, and healers of all types as well as to the general reading audience.

The idea that a long-lived form of spin order, namely singlet order, can be prepared from nuclear spin magnetisation first emerged in 2004. The unusual properties of singlet order–its long lifetime and the fact that it is NMR silent but interconvertible into other forms of NMR active order—make it a ‘smart tag’ that can be used to store information for a long time or through distant space points. It is not unexpected then, that since its first appearance, this idea has caught the attention of research groups interested in exploiting this form of order in different fields of research spanning from biology to materials science and from hyperpolarisation to quantum computing. This first book on the subject gives a thorough description of the various aspects that affect the development of the topic and details the interdisciplinary applications. The book starts with a section dedicated to the basic theories of long-lived spin order and then proceeds with a description of the state-of-the-art experimental techniques developed to manipulate singlet order. It then concludes by covering the generalization of the concept of singlet order by introducing and discussing other forms of long-lived spin order.

The application of biocatalysis in organic synthesis is rapidly gaining popularity amongst chemists. Compared to traditional synthetic methodologies biocatalysis offers a number of advantages in terms of enhanced selectivity (chemo-, regio-, stereo-), reduced environmental impact and lower cost of starting materials. Together these advantages can contribute to more sustainable manufacturing processes across a wide range of industries ranging from pharmaceuticals to biofuels. The biocatalytic toolbox has expanded significantly in the past five years and given the current rate of development of new engineered biocatalysts it is likely that the number of available biocatalysts will double in the next few years. This textbook gives a comprehensive overview of the current biocatalytic toolbox and also establishes new guidelines or rules for “biocatalytic retrosynthesis”. Retrosynthesis is a well known and commonly used technique whereby organic chemists start with the structure of their target molecule and generate potential starting materials and intermediates through a series of retrosynthetic disconnections. These disconnections are then used to devise a forward synthesis, in this case using biocatalytic transformations in some of the key steps. Target molecules are disconnected with consideration for applying biocatalysts, as well as chemical reagents and chemocatalysts, in the forward synthesis direction. Using this textbook, students will be able to place biocatalysis within the context of other synthetic transformations that they have learned earlier in their studies. This additional awareness of biocatalysis will equip students for the modern world of organic synthesis where biocatalysts play an increasingly important role. In addition to guidelines for identifying where biocatalysts can be applied in organic synthesis, this textbook also provides examples of current applications of biocatalysis using worked examples and case studies. Tutorials enable the reader to practice disconnecting target molecules to find the ‘hidden’ biocatalytic reactions which can be applied in the synthetic direction. The book contains a complete description of the current biocatalyst classes that are available for use and also suggests areas where new enzymes are likely to be developed in the next few years. This textbook is an essential resource for lecturers and students studying synthetic organic chemistry. It also serves as a handy reference for practicing chemists who wish to embed biocatalysis into their synthetic toolbox.

Chemistry is a conceptual subject and, in order to explain many of the concepts, teachers use models to describe the microscopic world and relate it to the macroscopic properties of matter. This can lead to problems, as a student's every-day experiences of the world and use of language can contradict the ideas put forward in chemical science. These titles have been designed to help tackle this issue of misconceptions. Part 1 deals with the theory, by including information on some of the key alternative conceptions that have been uncovered by research; ideas about a variety of teaching approaches that may prevent students acquiring some common alternative conceptions; and general ideas for assisting students with the development of appropriate scientific conceptions. Part 2 provides strategies for dealing with some of the misconceptions that students have, by including ready to use classroom resources including copies of probes that can be used to identify ideas held by students; some specific exercises aimed at challenging some of the alternative ideas; and classroom activities that will help students to construct the chemical concepts required by the curriculum. Used together, these two books will provide a good theoretical underpinning of the fundamentals of chemistry. Trialled in schools throughout the UK, they are suitable for teaching ages 11-18.

This new book presents a unified theoretical treatment, which is complete and rigorous but nonetheless readable. The theoretical treatment requires a variety of mathematical and physical tools. To keep the main text uncluttered, these tools are developed in comprehensive Appendices to which cross-references are made in the main text. These Appendices also ensure that the main text is useful to readers with a wide variety of scientific backgrounds and experience. These include not only spectroscopists, but also chemists, physicists, biochemists and analytical chemists. The presentation is such that postgraduate and postdoctoral students as well as more established research workers will find it valuable. About the Author The author was formerly Professor of Structural Chemistry and Director of the Molecular Spectroscopy unit in the University of Bradford. He is distinguished for his original scientific work in a number of areas of Raman spectroscopy. His book, 'Raman Spectroscopy', published in 1978 and long out of print, was highly successful. He has been co-editor of many books including the Specialist Reports on Molecular Spectroscopy, published by the Royal Society of Chemistry; he retired as Editor-in-Chief of the Journal of Raman Spectroscopy in December 1999.

Presents a fully interdisciplinary approach with a stronger emphasis on polymers and composites than traditional materials books Materials science and engineering is an interdisciplinary field involving the properties of matter and its applications to various areas of science and engineering. Polymer materials are often mixed with inorganic materials to enhance their mechanical, electrical, thermal, and physical properties. Materials: Introduction and Applications addresses a gap in the existing textbooks on materials science. This book focuses on three Units. The first, Foundations, includes basic materials topics from Intermolecular Forces and Thermodynamics and Phase Diagrams to Crystalline and Non-Crystalline Structures. The second Units, Materials, goes into the details of many materials including Metals, Ceramics, Organic Raw Materials, Polymers, Composites, Biomaterials, and Liquid Crystals and Smart Materials. The third and final unit details Behavior and Properties including Rheological, Mechanical, Thermophysical, Color and Optical, Electrical and Dielectric, Magnetic, Surface Behavior and Tribology, Materials, Environment and Sustainability, and Testing of Materials. Materials: Introduction and Applications features: Basic and advanced Materials concepts Interdisciplinary information that is otherwise scattered consolidated into one work Links to everyday life application like electronics, airplanes, and dental materials Certain topics to be discussed in this textbook are more advanced. These will be presented in shaded gray boxes providing a two-level approach. Depending on whether you are a student of Mechanical Engineering, Electrical Engineering, Engineering Technology, MSE, Chemistry, Physics, etc., you can decide for yourself whether a topic presented on a more advanced level is not important for you—or else essential for you given your professional profile Witold Brostow is Regents Professor of Materials Science and Engineering at the University of North Texas.

First published in 1959, Walford's guide to reference material achieved international recognition as a leading bibliographic tool across all subject areas. But, in the 1990s, the web transformed the information universe; and so we have now transformed Walford. The New Walford (TNW) Volume 1: Science, Technology and Medicine is the first volume of a radically different guide. Published over 3 years, TNW will form the most substantial work of its kind in the English language. This book provides a pathway through the huge quantity of information now accessible via the web. The types of material cited have been greatly widened to reflect the revolution brought about by the use of networked information; but we have made sure that print resources are not ignored where these are still valuable. If you are approaching a subject for the first time, TNW will get you on your way, guiding you to the best starting points for your query. For the information professional, TNW's new way of categorizing resources reflects the fundamental changes that have taken place in the scientific, business, political and social information landscapes. Who is it for This new reference book will be valuable for professionals worldwide who need to suggest resources to people who are relatively unfamiliar with the nuances of a topic and who need to know where to start. The focus is on resources that are most likely to be found and used within public, government, education or business information services. If you are an LIS professional responsible for developing and revising a reference collection, new to reference work, staffing an enquiry desk, a research worker or student, you'll welcome publication of this new work - it's your paper portal to the world of reference resources. Subject coverage mathematics physics & astronomy earth sciences chemistry biological sciences agriculture, forestry, fisheries & food pre-clinical sciences; clinical medicine health natural resources & energy engineering information & communication technology. Subject fields include astrophysics & cosmology biodiversity & conservation genetics, genomics & bioinformatics infectious diseases information system security meteorology & climatology microengineering & nanotechnology palaeontology soil science sports & exercise medicine.
