Book excerpt: Green chemistry is the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. Green polymer chemistry is an extension of green chemistry to polymer science and engineering. Developments in this area have been stimulated by health and environmental concerns, interest in sustainability, desire to decrease the dependence on petroleum, and opportunities to design and produce "green" products and processes. Major advances include new uses of biobased feedstock, green reactions, green processing methodologies, and green polymeric products. A current feature of green polymer chemistry is that it is both global and multidisciplinary. Thus, publications in this field are spread out over different journals in different countries. Moreover, a successful research effort may involve collaborations of people in various disciplines, such as organic chemistry, polymer chemistry, material science, chemical engineering, biochemistry, molecular biology, microbiology, enzymology, toxicology, environmental science, and analytical chemistry. This book combines the major interdisciplinary research in this field and is targeted for scientists, engineers, and students, who are involved or interested in green polymer chemistry. These may include chemists, biochemists, material scientists, chemical engineers, microbiologists, molecular biologists, enzymologists, toxicologists, environmental scientists, and analytical chemists. It can be a textbook for a course on green chemistry and also a reference book for people who need information on specific topics involving biocatalysis and biobased materials.

Download or read book Modification of Polymers written by Charles E. Carraher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sheer volume of topics which could have been included under our general title prompted us to make some rather arbitrary decisions about content. Modification by irradiation is not included because the activity in this area is being treated elsewhere. We have chosen to emphasize chemical routes to modification and have striven to pre sent as balanced a representation of current activity as time and page count permit. Industrial applications, both real and potential, are included. Where appropriate, we have encouraged the contributors to include review material to help provide the reader with adequate context. The initial chapter is a review from a historical perspective of polymer modification and contains an extensive bibliography. The remainder of the book is divided into four general areas: Reactions and Preparation of Copolymers Reactions and Preparation of Block and Graft Copolymers Modification Through Condensation Reactions Applications The chemical modification of homopolymers such as polyvinylchlo ride, polyethylene, poly(chloroalkylene sulfides), polysulfones, poly chloromethylstyrene, polyisobutylene, polysodium acrylate, polyvinyl alcohol, polyvinyl chloroformate, sulfonated polystyrene; block and graft copolymers such as poly(styrene-block-ethylene-co-butylene block-styrene), poly(I,4-polybutadiene-block ethylene oxide), star chlorine-telechelic polyisobutylene, poly(isobutylene-co-2,3-dimethyl- 1,3-butadiene), poly(styrene-co-N-butylmethacrylate); cellulose, dex tran and inulin, is described.

Download or read book Oxidoreductase written by and published by BoD – Books on Demand. This book was released on 2021-02-17 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidoreductase enzymes are a group of enzymes that catalyzes the transfer of electrons from one molecule, the reductant, also called the electron donor, to another, the oxidant, also called the electron acceptor. Oxidoreductase enzymes utilize NADP+ or NAD+ as cofactors. Oxidoreductase enzymes include the following: oxidase, dehydrogenase, peroxidase, hydroxylase, oxygenase, and reductase. Most oxidoreductase enzymes are dehydrogenases. However, reductases are also common. The accepted nomenclature for dehydrogenases is “donor dehydrogenase”, where the donor is the oxidized substrate. Metabolic abnormalities disorders resulting from a deficiency (quantitative and qualitative) or from over-activity of oxidoreductase, which may contribute to the decreased normal performance of life, are becoming common. This book covers the potential applications of oxidoreductases on the growth of oxidoreductase-based diagnostic tests and better biosensors in the design of inventive systems for crucial co-enzyme generations and in the synthesis of polymers and organic substrates. The book describes the role of oxidoreductase as essential in medical drug formation. It can be employed to produce a huge amount of compounds that act as medical mediators like Cephalosporin (beta lactam antibiotic). Furthermore, the idea of how to use different enzymes as targets for medical treatment in different types of cancers is also described in this book.
