This primer provides an introduction to the subject of surfaces at the level of undergraduates and first year postgraduates. There are four chapters, the first concerns basic thermodynamic material used to understand the properties of surfaces including; surface tension, Gibbs adsorption, surface pressure and surface phase equilibria, surfactants and micelles, wetting, detergency, and contact angle. The second chapter concentrates on gas adsorbtion at solid surfaces and covers topics including adsorbtion, Langmuir isotherms, heats of adsorbtion, BET isotherms, physisorbtion, chemisorbtion, precursor adsorbtion kinetics, well-defined surfaces, UHV, surface sensitivity and selectivity, surface diffusion and electrons interacting with matter. Chapter three then outlines the physico- chemical principles of XPS, AES, LEED, STM, AFM, work function measurements, UPS, TPD, molecular beams, HREELS and PAIRS and the types of fundamental surface information each of these techniques provides. The final chapter contains a series of worked examples and problems, bringing together the various strands developed in Chapters 1-3 in order to elucidate surface phenomena. The book is unique in its mix of 'Classical' and 'Modern' surface science and should be relevant to physicists, chemists and material scientists.

The fern-like patterns of frost on a cold window, eroded landscapes, and particles grown in an aerosol all have forms that are conventionally regarded as irregular, with little or no symmetry. In this book the reader is introduced to the fractal dimension, a concept that unifies the description of such diverse and irregular objects and implies that they all possess a new form of symmetry. The growth of these different objects is controlled by similar simple processes; descriptions of simple experiments that will bring the principles involved to life in a modestly equipped laboratory are also provided. The relevance of fractal concepts to the structure and chemistry of porous solids, and to the growth of polymers and colloids in liquid and gaseous phases, is emphasized within this concise text.

Thoroughly updated, Introduction to Polymers, Third Edition presents the science underpinning the synthesis, characterization and properties of polymers. The material has been completely reorganized and expanded to include important new topics and provide a coherent platform for teaching and learning the fundamental aspects of contemporary polymer science. New to the Third Edition Part I This first part covers newer developments in polymer synthesis, including ‘living’ radical polymerization, catalytic chain transfer and free-radical ring-opening polymerization, along with strategies for the synthesis of conducting polymers, dendrimers, hyperbranched polymers and block copolymers. Polymerization mechanisms have been made more explicit by showing electron movements. Part II In this part, the authors have added new topics on diffusion, solution behaviour of polyelectrolytes and field-flow fractionation methods. They also greatly expand coverage of spectroscopy, including UV visible, Raman, infrared, NMR and mass spectroscopy. In addition, the Flory–Huggins theory for polymer solutions and their phase separation is treated more rigorously. Part III A completely new, major topic in this section is multicomponent polymer systems. The book also incorporates new material on macromolecular dynamics and reptation, liquid crystalline polymers and thermal analysis. Many of the diagrams and micrographs have been updated to more clearly highlight features of polymer morphology. Part IV The last part of the book contains major new sections on polymer composites, such as nanocomposites, and electrical properties of polymers. Other new topics include effects of chain entanglements, swelling of elastomers, polymer fibres, impact behaviour and ductile fracture. Coverage of rubber-toughening of brittle plastics has also been revised and expanded. While this edition adds many new concepts, the philosophy of the book remains unchanged. Largely self-contained, the text fully derives most equations and cross-references topics between chapters where appropriate. Each chapter not only includes a list of further reading to help readers expand their knowledge of the subject but also provides problem sets to test understanding, particularly of numerical aspects.

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.

Intrigued as much by its complex nature as by its outsider status in traditional organic chemistry, the editors of The Organic Chemistry of Sugars compile a groundbreaking resource in carbohydrate chemistry that illustrates the ease at which sugars can be manipulated in a variety of organic reactions. Each chapter contains numerous examples demonstrating the methods and strategies that apply mainstream organic chemistry to the chemical modification of sugars. The book first describes the discovery, development, and impact of carbohydrates, followed by a discussion of protecting group strategies, glycosylation techniques, and oligosaccharide syntheses. Several chapters focus on reactions that convert sugars and carbohydrates to non-carbohydrate molecules including the substitution of sugar hydroxyl groups to new groups of synthetic or biological interest, cyclitols and carbasugars, as well as endocyclic heteroatom substitutions. Subsequent chapters demonstrate the use of sugars in chiral catalysis, their roles as convenient starting materials for complex syntheses involving multiple stereogenic centers, and syntheses for monosaccharides. The final chapters focus on new and emerging technologies, including approaches to combinatorial carbohydrate chemistry, the biological importance and chemical synthesis of glycopeptides, and the medicinally significant concept of glycomimetics. Presenting the organic chemistry of sugars as a solution to many complex synthetic challenges, The Organic Chemistry of Sugars provides a comprehensive treatment of the manipulation of sugars and their importance in mainstream organic chemistry. Daniel E. Levy, editor of the Drug Discovery Series, is the founder of DEL BioPharma, a consulting service for drug discovery programs. He also maintains a blog that explores organic chemistry.

This book will allow students to see how the organic chemistry taught in undergraduate courses is applied by medicinal chemists in industry. Many of today's best selling drugs are first made in the chemical laboratory on a very small scale many years before they enter the market place. During the intervening period, organic chemists investigate alternative methods both to improve the overall yield of the process and to ensure that it operates safely on a manufacturing scale. This book describes briefly how each drug works and then reviews the most efficient routes to their synthesis.
