Over the past few decades, experimental excited state chemistry has moved into the femtochemistry era, where time resolution is short enough to resolve nuclear dynamics. Recently, the time resolution has moved into the attosecond domain, where electronic motion can be resolved as well. Theoretical chemistry is becoming an essential partner in such experimental investigations; not only for the interpretation of the results, but also to suggest new experiments.This book provides an integrated approach. The three main facets of excited-state theoretical chemistry; namely, mechanism, which focuses on the shape of the potential surface along the reaction path, multi-state electronic structure methods, and non-adiabatic dynamics, have been brought together into one volume. Theoretical Chemistry for Electronic Excited States is aimed at both theorists and experimentalists, involved in theoretical chemistry, in electronic structure computations and in molecular dynamics. The book will provide both with the knowledge and understanding to discover ways to work together more closely through its unified approach.
Continuous professional development of chemistry teachers is essential for any effective chemistry teaching due to the evolving nature of the subject matter and its instructional techniques. Professional development aims to keep chemistry teaching up-to-date and to make it more meaningful, more educationally effective, and better aligned to current requirements.Presenting models and examples of professional development for chemistry teachers, from pre-service preparation through to continuous professional development, the authors walk the reader through theory and practice. The authors discuss factors which affect successful professional development, such as workload, availability and time constraints, and consider how we maintain the life-long learning of chemistry teachers. With a solid grounding in the literature and drawing on many examples from the authors' rich experiences, this book enables researchers and educators to better understand teachers' roles in effective chemistry education and the importance of their professional development.
Formaldehyde is virtually ubiquitous in the modern environment due to its cost-effective nature, its use in resin formation, and its preservative properties. Though formaldehyde is necessary for many products and processes important to the world's economy, this economic dependence on formaldehyde comes at a cost to public health. Growth and consequent industrialization rely heavily on formaldehyde use. New buildings-residences, public places, and offices-are not only built with timber preserved by formaldehyde, but they are also furnished with wood, wool, and textile products that contain formaldehyde. The general population faces environmental exposure from indoor and outdoor air pollution, food, and even medicine. Scientific inquiry into formaldehyde exposure has grown in response. This book consolidates the new and established body of formaldehyde research in the scholarly community, focusing on exposure, genotoxicity, and adverse health outcomes. Through this resource, we hope to increase awareness of the broad range of health effects posed by formaldehyde exposure, and to encourage interdisciplinary interest, as well as research, into this pervasive compound-especially in the United States and China, where formaldehyde production and usage is high. This book will be useful to researchers of environmental and occupational exposure, students, and government regulators and anyone exposed to formaldehyde in the workplace and/or at home.
New materials are required to solve global challenges such as the growing energy demand and reducing the threat of new and re-emerging diseases and infections. Metallopolymers is an exciting and promising area of research and this book focuses on the strategy of incorporating transition metals into macromolecules to design functional materials for addressing such problems.The book starts with an introduction to current global challenges and the role of materials science in tackling these, it then discusses the fundamentals of metallopolymers and their synthesis. The final chapters look at specific applications of the materials from photovoltaics and light-emitting diodes for energy conservation, to biological sensors and drug delivery platforms.Written by leading experts in the field, this book is an ideal reference for students and researchers working in polymer chemistry, organometallic chemistry and materials science interested in both the polymers and their applications in energy and health.
This book is aimed at informing organic chemists and natural products chemists on the use of NMR for structure elucidation to enable them to ensure they yield the most reliable possible data in the minimum possible time. It covers the latest pulse sequences, acquisition and processing methods, practical areas not covered in most texts e.g. detailed consideration of the relative advantages and disadvantages of different pulse sequences, choosing acquisition and processing parameters to get the best possible data in the least possible time, pitfalls to avoid and how to minimize the risks of getting wrong structures. Useful in industrial, pharma or research environments, this reference book is for anyone involved with organic chemistry research and, in particular, natural products research requiring advice for getting the best results from the NMR facilities.
In recent years, the use of illegal substances has increased, particularly 'designer' drugs which have rapidly become part of youth culture. The need for all involved in drug control to have up to date information about the subject has never been greater. This book helps meet this need by providing a chemical background to the legal controls on drugs of abuse. Although focussed on the UK, some of the provisions of the Misuse of Drugs Act derive from international treaties; the discussion of technical aspects is therefore of wider relevance. Apart from the Act itself, the book also deals with certain aspects of the Misuse of Drugs Regulations. There is detailed coverage of 'designer drugs' and the generic legislation that was introduced to tackle them. The more recent addition of 35 'Ecstasy'-like substances is covered in depth. The significance to the legislation of terms such as salt, base, stereoisomer, ester, ether, derivative, homologue and isotope are described, and the text is supplemented by 23 Tables and over 80 chemical structures. There are eleven Appendices covering topics such as precursor chemicals, related legislation, stated cases, sentencing guidelines and the chemical characteristics of commonly-abused drugs. Up-to-date lists of controlled drugs, with cross references to their status in UN treaties, are provided and a number of pending and other possible changes to the Act are included together with a guide to nomenclature and synonyms. Although primarily aimed at forensic scientists, this book will be of great benefit to all bodies concerned with drug control, including the police, customs officers, lawyers and government departments.

The vast majority of drugs are organic molecular entities. A clear understanding of the organic chemistry of drug degradation is essential to maintaining the stability, efficacy, and safety of a drug product throughout its shelf-life. During analytical method development, stability testing, and pharmaceutical manufacturing troubleshooting activities, one of the frequently occurring and usually challenging events would be the identification of drug degradants and understanding of drug degradation mechanisms and pathways. This book is written by a veteran of the pharmaceutical industry who has first-hand experience in drug design and development, drug degradation mechanism studies, analytical development, and manufacturing process troubleshooting and improvement. The author discusses various degradation pathways with an emphasis on the mechanisms of the underlying organic chemistry, which should aid greatly in the efforts of degradant identification, formulation development, analytical development, and manufacturing process improvement. Organic reactions that are significant in drug degradation will first be reviewed and then illustrated by examples of drug degradation reported in the literature. The author brings the book to a close with a final chapter dedicated to the strategy for rapid elucidation of drug degradants with regard to the current regulatory requirements and guidelines. One chapter that should be given special attention is Chapter 3, Oxidative Degradation. Oxidative degradation is one of the most common degradation pathways but perhaps the most complex one. This chapter employs more than sixty drug degradation case studies with in-depth discussion in regard to their unique degradation pathways. With the increasing regulatory requirements on the quality and safety of pharmaceutical products, in particular with regard to drug impurities and degradants, the book will be an invaluable resource for pharmaceutical and analytical scientists who engage in formulation development, analytical development, stability studies, degradant identification, and support of manufacturing process improvement. In addition, it will also be helpful to scientists engaged in drug discovery and development as well as in drug metabolism studies.
It is believed that beer has been produced, in some form, for thousands of years - the ancient Egyptians being one civilization with a knowledge of the fermentation process. Beer production has seen many changes over the centuries, and Brewing, Second Edition brings the reader right up to date with the advances in the last decade. Covering the various stages of beer production, reference is also made to microbiology within the brewery and some pointers to research on the topic are given. Written by a recently retired brewer, this book will appeal to all beer-lovers, but particularly those within the industry who wish to understand the processes, and will be relevant to students of food or biological sciences.
During the last two decades, the use of NMR spectroscopy for the characterization and analysis of food materials has flourished, and this trend continues to increase today. Currently, there exists no book that fulfils specifically the needs of food scientists that are interested in adding or expanding the use of NMR spectroscopy in their arsenal of food analysis techniques. Current books and monographs are rather addressed to experienced researchers in food analysis providing new information in the field. This book, written by acknowledged experts in the field, fills the gap by offering a day to day NMR guide for the food scientist, affording not only the basic theoretical aspects of NMR spectroscopy, but also practical information on sample preparation, experimental conditions and data analysis. Current developments in the field covered in this book are the availability of solid state NMR experiments such as CP/MAS and more importantly HR-MAS NMR for the analysis of semisolid foods, and the increasing use of chemometrics to analyze NMR data in food metabonomics. Moreover, this book contains an up to date discussion of MRI in food analysis including topics such as food processing and natural changes in food such as ripening. The book is a compact and complete source of information for food scientists who wish to apply methodologies based on NMR spectroscopy in food analysis. It contains information so far scattered in the primary literature, in NMR treatises and food analysis books, in a concise format that makes it appealing to food scientists who have no or minimal experience in magnetic resonance techniques. The inclusion of practical information about NMR instrumentation, experiment setup, acquisition and spectral analysis for the study of different food categories make this book a hands-on manual for food scientists wishing to implement novel NMR spectroscopy-based analytical techniques in their field.
Computational Quantum Chemistry presents computational electronic structure theory as practised in terms of ab initio waveform methods and density functional approaches. Getting a full grasp of the field can often prove difficult, since essential topics fall outside of the scope of conventional chemistry education. This professional reference book provides a comprehensive introduction to the field.Postgraduate students and experienced researchers alike will appreciate Joseph McDouall's engaging writing style. The book is divided into five chapters, each providing a major aspect of the field. Electronic structure methods, the computation of molecular properties, methods for analysing the output from computations and the importance of relativistic effects on molecular properties are also discussed. Links to the websites of widely used software packages are provided so that the reader can gain first hand experience of using the techniques described in the book.Dr McDouall has more than 25 years experience in theoretical chemistry; as a reader at the University of Manchester his research interests include the application of quantum chemical methods to the elucidation of chemical problems and the development and implementation of electronic structure methods that permit the accurate prediction of chemical structures and molecular properties.
Confectionery is a topic close to many people's hearts and its manufacture involves some interesting science. The confectionery industry is divided into three classes: chocolate, flour and sugar confectionery. It is the background science of this latter category that is covered in The Science of Sugar Confectionery. The manufacture of confectionery is not a science based industry, as these products have traditionally been created by skilled confectioners working empirically. In fact, scientific understanding of the production process has only been acquired retroactively. Historically however, sugar confectionery has had technological synergies with the pharmaceutical industry, such as making sugar tablets and applying panned sugar coatings. This book gives an introduction to the subject, with some basic definitions and commonly used ingredients and then moves on to discuss the chemistry of various types of sugar confectionery. These include "e;sugar glasses"e; (boiled sweets), "e;grained sugar products"e; (fondants), toffees and fudges, "e;hydrocolloids"e; (gums, pastilles and jellies) and concludes with a chapter dedicated to sugar-free confectionery.
In the past decade a new era in asymmetric catalysis has been realised by the discovery of L-proline induced chiral enamines from carbonyls. Inspired by this, researchers have developed many other primary catalytic species in situ, more recently secondary catalytic species such as aminals have been identified for use in asymmetric synthesis.High-yielding asymmetric synthesis of bioactive and natural products through mild catalysis is an efficient approach in reaction engineering. In the early days, synthetic chemists mainly focused on the synthesis of complex molecules, with less attention on the reaction efficiency and eco-friendly conditions. Recent investigations have been directed towards the development of atom economy, eco-friendly and enantioselective synthesis for more targeted and efficient synthesis.Building on the momentum of this rapidly expanding research area, Dienamine Catalysis for Organic Synthesis will provide a comprehensive introduction, from the preformed species, in situ generation and onto their applications in the synthesis of bioactive molecules and natural products.
The coupling of mass spectrometry or nuclear magnetic resonance to chromatography has broadened the possibilities for determining organic reaction mechanisms. And while many results have been published reporting these, even more can be achieved through modern computational methods. Combining computational and theoretical techniques with advanced chromatographic methods offers a powerful tool for quantitatively determining molecular interactions .This book presents the possibilities for characterising biological applications by combining analytical and computational chemistries. Written by the author of "e;HPLC: A Practical Guide"e; (RSC, 1999), the book examines not only the behaviour of biological reactions per se, but also describes the behaviour of biological molecules in chromatography systems. Various software packages are reviewed, and most computations can be performed on a standard PC using accessible software. Consideration is given to a variety of chromatographic techniques and strategies for high-sensitivity detection are presented.The first book of its kind, it will inspire readers to explore the possibilities of combining these techniques in their own work, whether at an industrial or academic level.
Postgraduates and experienced researchers will benefit from the comprehensive nature of the book, as will manufacturers of quantum dots and those wishing to apply them.
This book will provide an understanding of the behavioural properties of water which is fundamental to gaining an appreciation of many scientific processes and principles.
With a foreword from leading organic chemist Professor Paul Wender, this book collects the major developments reported in the past thirty years in the field of enantioselective reactions promoted by chiral cobalt catalysts.
Disability studies have long been the domain of medical and pedagogical academics. However, in recent years, the subject has outgrown its clinical origins. In Freaks of History, James MacDonald presents two dramatic explorations of disability within the wider themes of sexuality, gender, foreignness, and the Other. Originally directed by Martin Harvey and performed by undergraduate students at the University of Exeter, Wellclose Square and Unsex Me Here analyze cultural marginalization against the backdrop of infamous historical events. MacDonald, who is cerebral palsied, recognizes that disability narratives are rarely written by and for disabled people. Therefore his plays, accompanied by critical essays and director's notes, are a welcome addition to the emerging discourse of Crip theory, and essential reading for disability students and academics alike.
