Taschenbuch. Zustand: Neu. Neuware - The main aim of this unique book is to introduce the student to spectroscopy in a clear manner which avoids, as far as possible, the mathematical aspects of the subject.

Taschenbuch. Zustand: Neu. Neuware - The chemical sciences pervade almost all aspects of modern day life from the clothes we wear, the food we eat, to the pastimes we enjoy. This resource shows how a combination of modern techniques are used to ensure that horseracing is both fair and prevents abuse of the horses involved. The material is based on the work of the Horseracing Forensic Laboratory (HFL) located near Newmarket in Suffolk where samples of urine and sometimes blood from racehorses are screened to detect and identify traces of prohibited substances. All the material and activities have been compiled by Ted Lister who worked with a group of teachers on a writing workshop. It is hoped teachers will use it to provide an up-to-date and interesting context for their work and so enthuse the next generation of scientists.

Taschenbuch. Zustand: Neu. Neuware - 'Alkenes and Aromatics' examines the reaction mechanisms associated with carbon-carbon double bonds, and then goes on to look at aromatic substitution (nitration, halogenation, sulfonation and Friedel Crafts reactions). The formation and reactions of diazonium ions are also discussed. This knowledge is then applied to the synthesis of pseudoephedrine, highlighting the key aspects of synthesis, such as yields, stereochemistry and reaction conditions. A Case Study on the organic chemical industry completes the book, providing a background as to why understanding organic reactions is so important. The Molecular World series provides an integrated introduction to all branches of chemistry for both students wishing to specialise and those wishing to gain a broad understanding of chemistry and its relevance to the everyday world and to other areas of science. The books, with their Case Studies and accompanying multi-media interactive CD-ROMs, will also provide valuable resource material for teachers and lecturers. TOC:n/a.

Taschenbuch. Zustand: Neu. Neuware - Often considered as a simple task, chemical analysis actually requires a variety of quite complex skills. As a practitioner in an interdisciplinary science, the analytical scientist is relied upon to have the knowledge and skill to help solve problems or to provide relevant information. They will need to think laterally, examining the process from sampling to final result carefully, in addition to selecting the appropriate technique in order to satisfy the objective and obtain a reliable result. The aim of this book is to provide basic training in the whole analytical process for students, demonstrating why analysis is necessary and how to take samples, before they attempt to carry out any analysis in the laboratory. Initially, planning of work, and collection and preparation of the sample are discussed in detail. This is followed by a look at issues of quality control and accreditation and the basic equipment (e.g. balances and glassware) and techniques that are required. Throughout, safety issues are addressed, and examples and practical exercises are given.

Taschenbuch. Zustand: Neu. Neuware - Chemical Kinetics and Mechanism considers the role of rate of reaction. It begins by introducing chemical kinetics and the analysis of reaction mechanism, from basic well-established concepts to leading edge research. Organic reaction mechanisms are then discussed, encompassing curly arrows, nucleophilic substitution and E1 and E2 elimination reactions. The book concludes with a Case Study on Zeolites, which examines their structure and internal dimensions in relation to their behaviour as molecular sieves and catalysts. The accompanying CD-ROM contains the 'Kinetics Toolkit', a graph- plotting application designed for manipulation and analysis of kinetic data, which is built into many of the examples, questions and exercises in the text. There are also interactive activities illustrating reaction mechanisms. The Molecular World series provides an integrated introduction to all branches of chemistry for both students wishing to specialise and those wishing to gain a broad understanding of chemistry and its relevance to the everyday world and to other areas of science. The books, with their Case Studies and accompanying multi-media interactive CD-ROMs, will also provide valuable resource material for teachers and lecturers. TOC:n/a.

Taschenbuch. Zustand: Neu. Neuware - The three-dimensional aspects of molecular shape can be crucial to both properties and reactions. The Third Dimension explores the arrangements of atoms in molecules and in different types of solids. Initial chapters describe the common crystal structures and how they are related to close-packed arrangements of ions. Metallic, ionic, molecular and extended covalent crystals are covered; major types of crystal defects are also discussed. The book then introduces isomerism, and explores the stereochemical consequences of the tetrahedral carbon atom. Chirality is also investigated. The book concludes with a Case Study on Liquid Crystals, which describes structures, properties and applications. As visualisation in 3D is an important part of this book, the accompanying CD-ROMs provide video material, interactive questions and exercises using models to aid understanding of crystals, organic molecules and stereochemistry, All necessary programs are provided.

Buch. Zustand: Neu. Neuware - Implants into the human body, such as hip joints, heart valves and dental crowns, have been increasingly used over the last 40 years or so, and many patients have benefited from their use. But how much is known about the metals, ceramics and polymers that are used in these repairs This book provides a state-of-the-art account of the chemistry of the synthetic materials used in medicine and dentistry. It looks at the properties and interactions of these materials within the body at a molecular level, and includes discussion of bioengineering and cell biology. In addition, there is an account of the surgical procedures used, as well as extensive coverage of the possible biological reactions to the presence of foreign materials in the body. A brief look at the emerging field of tissue engineering completes the text.
