The coverage of reaction dynamics is very broad, so many students studying chemical physics will find elements of this text interesting and useful. Tutorials in Molecular Reaction Dynamics includes extensive references to more advanced texts and research papers, and a series of 'Study Boxes' help readers grapple with the more difficult concepts. Each chapter is thoroughly cross-referenced, helping the reader to link concepts from different branches of the subject. Worked problems are included, and each chapter concludes with a selection of problems designed to test understanding of the subjects covered. Supplementary reading material, and worked solutions to the problems, are contained on a secure website.

The world is not at equilibrium, and the events that give vitality and movement are transitions towards equilibrium from the present state of imbalance. Chemical transformations often contribute fundamentally to this process and their study is challenging and important. The early chapters of this text provide a basic introduction to the kinetics of simple and complex reaction systems in solution. The remaining chapters present a treatment of the more advanced topics, comprising solvent effects, fast reaction techniques, and heterogeneous liquid - liquid two-phase systems. The last introduces currently active and important research areas in solution kinetics, including phase-transfer catalysis, and diffusion and transport in chemical and biological membranes.

Supramolecular Chemistry

From Molecules to Nanomaterials

Publisher: Wiley
ISBN: 9780470746400
Category: Science
Page: 4014
View: 429
Supramolecular Chemistry: From Molecules to Nanomaterials is a new major reference work which links supramolecular chemistry and nanomaterials. Presenting over 150 tutorial articles and spanning over 10 comprehensive sections, this new resource covers: Concepts Techniques Molecular recognition Supramolecular reactivity Supramolecular aspects of chemical biology Self processes Supramolecular devices Supramolecular materials chemistry Soft matter Nanotechnology Supramolecular chemistry is 'chemistry beyond the molecule'. While traditional chemistry focuses on the bonds that hold atoms together in a molecule, supramolecular chemistry examines the weaker interactions that hold groups of molecules together. Important concepts that have been demonstrated by supramolecular chemistry include molecular self-assembly, folding, molecular recognition, host-guest chemistry, mechanically-interlocked molecular architectures, and dynamic covalent chemistry. The importance of supramolecular chemistry was established by the 1987 Nobel Prize for Chemistry, which was awarded to Donald J. Cram, Jean-Marie Lehn, and Charles J. Pedersen in recognition of their work in the field. The past decade has seen dramatic developments in the field, with supramolecular chemistry leaving its roots in classical host guest chemistry and expanding into exciting areas of materials chemistry and nanoscience with many real and potential applications. Supramolecular findings are evolving our understanding of the way chemical concepts at the molecular level build up into materials and systems with fascinating, emergent properties on the nanoscale. Supramolecular chemistry: the biggest challenge yet! "Creating that link between the chemist's understanding of the way in which molecules interact with one another, and the understanding a materials scientist, engineer or biologist has of the resulting properties of a material or system comprised of those molecules is one of the huge grand challenges facing modern molecular science." —Philip A. Gale and Jonathan W. Steed, Editors-in-Chief Linking supramolecular chemistry and nanotechnology to define the field in the 21st Century… Supramolecular Chemistry: From Molecules to Nanomaterials is the first major reference to link supramolecular chemistry and nanotechnology. A global team of experts present an overview of the concepts and techniques of modern supramolecular chemistry, demonstrating how these paradigms evolve into nanoscale systems chemistry, nanotechnology, materials science and beyond. Breaking down the barriers between synthetic chemistry and materials science, the authors demonstrate how modern techniques allow access increasingly far along the 'synthesising-up' pathway. Supramolecular Chemistry: From Molecules to Nanomaterials explains the fundamental concepts and provides invaluable practical guidance on the applications and limitations of modern instrumental techniques for addressing molecular and materials-based problems. The printed edition of Supramolecular Chemistry: From Molecules to Nanomaterials is available as an eight-volume set. Publishing in full colour to enhance the interpretation of complex supramolecular structures the printed edition is highly illustrated with an average of three images per page features fully indexed articles with cross-references integrated into the text includes a glossary of key terms Online Edition Supramolecular Chemistry: From Molecules to Nanomaterials is now available online.

Chemistry of Peptide Synthesis


Author: N. Leo Benoiton
Publisher: CRC Press
ISBN: 1420027697
Category: Science
Page: 304
View: 8324
Chemistry of Peptide Synthesis is a complete overview of how peptides are synthesized and what techniques are likely to generate the most desirable reactions. Incorporating elements from the author’s role of Career Investigator of the Medical Research Council of Canada and his extensive teaching career, the book emphasizes learning rather than memorization. The text uses clear language and schematics to present concepts progressively, carefully excluding unnecessary details and providing a historical context in which to appreciate the development of the field. The author first outlines the fundamentals of peptide synthesis, focusing on the intermediates in aminolysis reactions. Gradually the text builds into discussions of the applicability of coupling reactions, stereomutation, methods of deprotection, solid-phase synthesis, side-chain protection and side reactions, and amplification on coupling methods. The book clarifies the differences between oxazolones from amino-acid derivatives and segments and the implications of their formation on the chiral integrity of products. The author offers a critical analysis of the mechanisms of coupling reactions and the desirability of preactivation. The text explains hindrance and the nucleophilicity of tertiary amines and rationalizes their use. The book also explores mechanisms of acidolysis and the dual role of nucleophiles as reactants and scavengers. Chemistry of Peptide Synthesis supplies a broad, yet straightforward approach that appeals to those with limited knowledge of organic chemistry or chemists from other fields as well as in-depth coverage that can be appreciated by experienced peptidologists.
