Download or read book Quaternary Ammonium Salts written by R. Alan Jones and published by Elsevier. This book was released on 2000-11-14 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text provides experimental methods for a wide range of organic reactions, systematically arranged according to reaction type, and describes the advantages and limitations of the procedures. Traditional methods to speed up organic reactions involve energy-consuming processes and costly and environmentally "unfriendly" solvents. Additionally, isolation of the product requires energy and time-consuming purification processes. A simple solution, especially for reactions involving anionic reactants, is the use of phase-transfer catalysis. Quaternary ammonium cations have the ability to transfer the anionic reactants as non-solvated ion-pairs from aqueous media into organic media. The resultant effect is to increase the rate of the organic reaction by enhancing the reactivity of the anionic species and increasing the encounter rate with the organic substrate. Side reactions are frequently eliminated so that the overall yield of the desired product is increased. Quaternary Ammonium Salts presents procedures for reducing reaction times and the need for extreme conditions, which are frequently encountered under standard reaction procedures. This is the only book to be published on quaternary ammonium salts. Best Synthetic Methods volumes allow the practicing synthetic chemist to choose between all the alternatives and assess their real advantages and limitations. Each volume of the series deals with a particular topic from a practical point of view, giving detailed examples and precise experimental directions and hints. With the emphasis on laboratory use, these volumes represent a comprehensive and practical guide to modern synthetic organic chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: Catalysis is a central topic in chemical transformation and energy conversion. Thanks to the spectacular achievements of colloidal chemistry and the synthesis of nanomaterials over the last two decades, there have also been significant advances in nanoparticle catalysis. Catalysis on different metal nanostructures with well-defined structures and composition has been extensively studied. Metal nanocrystals synthesized with colloidal chemistry exhibit different catalytic performances in contrast to metal nanoparticles prepared with impregnation or deposition precipitation. Additionally, theoretical approaches in predicting catalysis performance and understanding catalytic mechanism on these metal nanocatalysts have made significant progress. Metal Nanoparticles for Catalysis is a comprehensive text on catalysis on Nanoparticles, looking at both their synthesis and applications. Chapter topics include nanoreactor catalysis; Pd nanoparticles in C-C coupling reactions; metal salt-based gold nanocatalysts; theoretical insights into metal nanocatalysts; and nanoparticle mediated clock reaction. This book bridges the gap between nanomaterials synthesis and characterization, and catalysis. As such, this text will be a valuable resource for postgraduate students and researchers in these exciting fields.

Download or read book Antimicrobial Resistance in the Environment written by Patricia L. Keen and published by John Wiley & Sons. This book was released on 2012-01-24 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examines effects of the environmental distribution of antimicrobial resistance genes on human health and the ecosystem Resistance genes are everywhere in nature—in pathogens, commensals, and environmental microorganisms. This contributed work shows how the environment plays a pivotal role in the development of antimicrobial resistance traits in bacteria and the distribution of resistant microbial species, resistant genetic material, and antibiotic compounds. Readers will discover the impact of the distribution in the environment of antimicrobial resistance genes and antibiotics on both the ecosystem and human and animal health. Antimicrobial Resistance in the Environment is divided into four parts: Part I, Sources, including ecological and clinical consequences of antibiotic resistance by environmental microbes Part II, Fate, including strategies to assess and minimize the biological risk of antibiotic resistance in the environment Part III, Antimicrobial Substances and Resistance, including antibiotics in the aquatic environment Part IV, Effects and Risks, including the effect of antimicrobials used for non-human purposes on human health Recognizing the intricate links among overlapping complex systems, this book examines antimicrobial resistance using a comprehensive ecosystem approach. Moreover, the book's multidisciplinary framework applies principles of microbiology, environmental toxicology, and chemistry to assess the human and ecological risks associated with exposure to antibiotics or antibiotic resistance genes that are environmental contaminants. Each chapter has been written by one or more leading researchers in such fields as microbiology, environmental science, ecology, and toxicology. Comprehensive reference lists at the end of all chapters serve as a gateway to the primary research in the field. Presenting and analyzing the latest findings in a field of growing importance to human and environmental health, this text offers readers new insights into the role of the environment in antimicrobial resistance development, the dissemination of antimicrobial resistant genetic elements, and the transport of antibiotic resistance genes and antibiotics.

Available in PDF, EPUB and Kindle. Book excerpt: Biofilms are ubiquitous, yet until recently scientists and engineers involved in biofilm research or application had a severely limited insight into the structure and functioning of biofilms on a microbial level. However the past decade has seen an explosion of new techniques to elucidate the structure and functions of biofilms, e.g. molecular probes, microsensors, scanning electron microscopy, and a new generation of mathematical models. The 35 contributions selected for these proceedings after peer review reflect these developments with papers grouped into the following themes: nutrient removal systems; anaerobic systems; biofilm physical structure and aerobic water treatment; multidimensional modelling; detoxification of hazardous chemicals; and transport processes in and to the biofilm. The proceedings provide a unique panorama of the latest scientific tools, the emerging new concepts and the widespread applications that are making microbial ecology of biofilms such an exciting field. These genuinely state-of-the-art papers lay foundations for great progress in the next century.

This is the first single-author book on ionic liquids and the first introductory book on the topic. It is written in a clear, concise and consistent way. The book provides a useful introduction to ionic liquids for those readers who are not familiar with the topic. It is also wide ranging, embracing every aspect of the chemistry and applications of ionic liquids. The book draws extensively on the primary scientific literature to provide numerous examples of research on ionic liquids. These examples will enable the reader to become familiar with the key developments in ionic liquids chemistry over recent years. The book provides an introduction to: ionic liquids; their nomenclature; history; physical, chemical and biological properties; and their wide ranging uses and potential applications in catalysis, electrochemistry, inorganic chemistry, organic chemistry, analysis, biotechnology, green chemistry and clean technology. Notable and important chapters include "The Green Credentials of Ionic Liquids" and "Biotechnology." The chapter on "Applications" includes sections with brief descriptions of recent research on the development of ionic liquids: - for the construction of a liquid mirror for a moon telescope - for use as rocket propellants - for use as antimicrobial agents that combat MRSA - as active pharmaceutical ingredients and antiviral drugs - for embalming and tissue preservation Science students, researchers, teachers in academic institutions and chemists and other scientists in industry and government laboratories will find the book an invaluable introduction to one of the most rapidly advancing and exciting fields of science and technology today.
