Book Description
This volume is devoted to the developments in the branch of polymer chemistry which deals with immobilized systems. These systems are widely used in fields connected with metabolism in humans, animals, plants and micro-organisms. The study of these artificial immobilized systems permits the understanding and design of the function and behaviour of natural substances in living organisms. The book contains the latest achievements in the field of synthesis of polymeric derivatives of different natural substances such as: proteins; peptides; amino acids; poly- and monosaccharides; nucleic acids; nucleosides; nucleotides; coenzymes; vitamines; alkaloids; antibiotics; steroids; hormones; and others. Special attention is given to natural and synthetic carriers and the influence of their chemical structure on the efficiency of systems obtained.

Book Description
Enzyme immobilization has been approached for finding solutions for various critical problems associated with industries, medicine, environment, agriculture, etc. Especially since last decades, several innovative researches have come up to look for enhancing catalytic efficiency, reusability of immobilized enzyme and longer stability by introducing range of immobilizing supports, supports modifiers through introduction of several chemical agents (non-toxic) and adopting innovative enzyme immobilization methods. In the present book, polymeric supports have been focussed for enzyme immobilization, especially due to their versatility in immobilizing different enzymes for different large scale enzyme reactors to be used for several applications. Especially, polymers can be modified according to applications and enzyme properties which have made it supports of choice for all several enzyme based applications. Polymeric Supports for Enzyme Immobilization: Opportunities and Applications offers in-depth discussions of known polymeric enzyme support materials, reaction processes, and optimized methods to enhance enzyme immobilization. Case-based chapters examine methods of enzyme immobilization onto various polymeric supports, their surface chemistry and physical morphology followed by implementation of polymers based immobilized enzymes in various applications, viz. medicine, environment, industries, clean energy, disease diagnosis, drug delivery etc. This book has prime focus to allow several researchers across the world to provide updated technological details and incite to contribute more innovative work in coming years to find solutions to several critical problems. - Offers an in-depth, case-driven discussion of known polymeric enzyme support materials, associated reaction processes, and methods to enhance enzyme immobilization - Provides optimal strategies for various enzymes, processes, and applications, considering the enzyme itself, substrate, and available support properties - Provides complete details on applications of polymeric based immobilized enzymes in various applications ranging from chemical; or pharmaceutical synthesis, food processing, bioremediation, industrial catalysis, etc.

Book Description
This book reviews the current understanding of electronic, optical and magnetic properties of conjugated polymers in both the semiconducting and metallic states. It introduces in particular novel phenomena and concepts in these quasi one-dimensional materials that differ from the well-established concepts valid for crystalline semiconductors. After a brief introductory chapter, the second chapter presents basic theore tical concepts and treats in detail the various models for n-conjugated polymers and the computational methods required to derive observable quantities. Specific spatially localized structures, often referred to as solitons, polarons and bipolarons, result naturally from the interaction between n-electrons and lattice displacements. For a semi-quantitative understanding of the various measure ments, electron-electron interactions have to be incorporated in the models; this in turn makes the calculations rather complicated. The third chapter is devoted to the electrical properties of these materials. The high metallic conductivity achieved by doping gave rise to the expression conducting polymers, which is often used for such materials even when they are in their semiconducting or insulating state. Although conductivity is one of the most important features, the reader will learn how difficult it is to draw definite conclusions about the nature of the charge carriers and the microscopic transport mechanism solely from electrical measurements. Optical properties are discussed in the fourth chapter.

Book Description
This book presents the reader with a story-based narrative of discovery and development of radiation-induced graft polymerization. The report presented here accomplishes this by relating the inspiring account of research and development based on long-term collaboration among a professor, an engineer, and an entrepreneur. Their goal, ultimately successful, was to come up with a method for grafting functional polymer chains onto existing trunk polymers. The desired outcome was to produce feasible forms for practical use as adsorbents such as porous hollow-fiber membranes, porous sheets, nonwoven fabrics, and fibers. Adsorbents that specifically and efficiently bind to target ions and molecules are essential for capturing uranium species in seawater and antibody drugs in biological fluids and for removing metal ions from ultrapure water and radioactive cesium ions from contaminated water. This unique volume, with its clearly written text and many illustrative figures and diagrams, demonstrates the advantages of the high-adsorption capacity and rate and the easy handling of new polymeric adsorbents over conventional adsorbents. The dynamic behavior of graft chains as described here is certain to appeal especially to chemists, physicists, and material scientists as well as to other readers with an interest in this valuable subject.

Book Description
Deals with a new and promising field developed during the last two decades on the boundary between homogeneous and heterogeneous catalysis. This book presents general information on catalysis for a wide range of organic reactions, e.g., hydrogenation and oxidation reactions, and polymerization transformations. Special attention is paid to electro- and photochemical stimulation of catalytic processes in the presence of immobilized metal complexes. Other topics covered are the quantitative data on the comparison of catalyses by mobile and immobilized metal complexes; main factors affecting the activity of these catalytic systems and methods of optimizing their control; and specific problems of catalysis by fixed complexes (e.g., ligand exchange and electron transfer in metal polymer systems, macromolecular effects and polyfunctional catalysis).
