This book offers a comprehensive overview of the rapidly developing field of cluster science. In an interdisciplinary approach, basic concepts as well as recent developments in research and practical applications are authoritatively discussed by leading authors. Topics covered include 'naked' metal clusters, clusters stabilized by ligands, clusters in solids, and colloids. The reader will find answers to questions like: * How many metal atoms must a particle have to exhibit metallic properties? * How can the large specific surface of clusters and colloids be employed in catalysts? * How can metal clusters be introduced into solid hosts? * Which effects are responsible for the transition from isolated to condensed clusters? The editor has succeeded in bringing the contributions of various authors together into a homogeneous, readable book, which will be useful for the academic and industrial reader alike.
The essential introduction to the understanding of the structure of inorganic solids and materials. This revised and updated 2nd Edition looks at new developments and research results within Structural Inorganic Chemistry in a number of ways, special attention is paid to crystalline solids, elucidation and description of the spatial order of atoms within a chemical compound. Structural principles of inorganic molecules and solids are described through traditional concepts, modern bond-theoretical theories, as well as taking symmetry as a leading principle.

Neben der Methodenentwicklung ist die Optimierung bestehender Methoden eine zentrale Aufgabe im HPLC-Labor. Eine Aufgabe, die heute in immer kurzerer Zeit und kosteneffizient erledigt werden muss. Das Handbuch bietet eine fundierte Hilfe, um diese Herausforderung noch besser zu meistern. International renommierte Autoren wie John W. Dolan, Michael McBrien, Veronika R. Meyer, Uwe D. Neue, Lloyd R. Snyder oder Klaus K. Unger behandeln sowohl die allgemeinen Grundlagen und Strategien der Optimierung als auch die spezifischen Aspekte der unterschiedlichen Techniken wie RP-HPLC, NP-HPLC, Micro- und Nano-HPLC sowie der Kopplungstechniken wie LC-MS. Auch die richtige Saulenauswahl sowie Enantiomerentrennungen gehoren zu den behandelten Themen. Die Autoren liefern konkrete, praktische Tipps ebenso wie relevante Hintergrundinformationen. Sie bieten daruber hinaus Einblicke in die Optimierungspraxis sieben international renommierter Firmen verschiedener Branchen. Einige Beitrage stellen die Anwendung gangiger Optimierungssoftware wie DryLab oder ChromSword dar. Das ganze wird abgerundet durch praxisnahe Berichte erfahrener Anwender aus den verschiedenen Anwendungsgebieten, inbesondere aus den Life Sciences, wie beispielsweise Proteomics oder Pharmaentwicklung. Alle Beitrage sind in einem auf das Wesentliche konzentrierten und anwendungsnahen Stil geschrieben. Der Aufbau des Buches mit abgeschlossenen Kapiteln erleichtert das gezielte Nachschlagen.

Besides classical extraction techniques, it also provides an overview of ultrasound applications and devotes two chapters to proteomics and polymer technology. From the contents: * Common ultrasonic devices * Elemental speciation * On-line applications * Accelerated extraction of semivolatile and volatile organics * The ultrasonic bath vs. the ultrasonic probe * Liquid-liquid, liquid-solid and solid-liquid extraction * Solid-phase (micro)extraction * Stir bar sorptive extraction * Sonochemistry for organic and inorganic synthesis * Electrochemical applications * Applications to polymer science * Power ultrasound meets proteomics Of great interest to researchers in academia and industry, as well as analytical and natural products chemists, and those working in trace analysis.
Thoroughly revised, with either entirely new or completely updated contents, this is a practical manual for the small and large-scale preparation of enantiomerically pure products. The result is a vital resource for meeting the highest purity standards in the manufacture of chiral pharmaceuticals, food additives and related compounds. All the approaches covered here are highly relevant to modern manufacturing and quality control schemes in the pharmaceutical and biotech industries, addressing the increasingly important issue of drug safety in view of tougher regulatory standards worldwide.
This laboratory guide for successful electrophoretic separations is divided into two parts to provide readers with a thorough presentation of the fundamentals followed by a detailed description of the most common methods currently in use. This fourth edition retains the successful concept of its predecessors, yet features a brand-new layout, and is further enhanced by a section on difference gel electrophoresis, while the chapter on proteome analysis is practically all new and considerably extended, plus there are now around 10 % new literature references.
As analytical chemistry and biology move closer together, biologists are performing increasingly sophisticated analytical techniques on cells. Chemists are also turning to cells as a relevant and important sample to study newly developed methods. Practical Cell Analysis provides techniques, hints, and time-saving tips explaining what may be “common knowledge” to one field but are often hidden or unknown to another. Within this practical guide: The procedures and protocols for cell separation, handling cells on a microscope and for using cells in microfluidic devices are presented. Elements of cell culture are taken and combined with the practical advice necessary to maintain a cell lab and to handle cells properly during an analysis The main chapters deal with the fundamentals and applied aspects of each technique, with one complete chapter focusing on statistical considerations of analyzing cells Many diagram-based protocols for some of the more common cell processes are included Chapter summaries and extensive tables are included so that key information can be looked up easily in the lab setting Much like a good manual or cookbook this book is a useful, practical guide and a handy reference for all students, researchers and practitioners involved in cellular analysis.
Easy-to-follow guide helps you take full advantage of EPR spectroscopy's capabilities Electron Paramagnetic Resonance: A Practitioner's Toolkit serves as a practical guide that enables you to navigate through and make sense of the complex maze of electron paramagnetic resonance (EPR) spectroscopy fundamentals, techniques, and applications. The first half of this book is dedicated to explaining the core principles of EPR spectroscopy, using clear, easy-to-follow explanations and examples while avoiding complex physics and mathematics. The second half of the book focuses on applications, including problem-solving strategies for such fields as biology, medicine, material science, chemistry, physics, and radiation effects on matter. Carefully edited by two experienced EPR scientists, this book features a team of eighteen expert authors. Their contributions are based not only on a thorough examination and analysis of the primary literature, but also on their own firsthand experience in research and applications. As a result, the book is filled with practical advice, tips, and cautions addressing such issues as: Choosing the right experiment Selecting experimental parameters and sample size Avoiding setbacks and pitfalls Simulating the spectra With its straightforward explanations and clear examples, this book is just what researchers need to take full advantage of EPR spectroscopy's tremendous capabilities.
