Green polymer chemistry: biocatalysis and biomaterials   Publication : [S.l.] American Chemical Society 2011 . 478 p. , Green Polymer Chemistry is a crucial area of research and product development that continues to grow in its influence over industrial practices. Developments in these areas are driven by environmental concerns, interest in sustainability, desire to decrease our dependence on petroleum, and commercial opportunities to develop "green" products. Publications and patents in these fields are increasing as more academic, industrial, and government scientists become involved in research and commercial activities. The purpose of this book is to publish new work from a cutting-edge group of leading international researchers from academia, government, and industrial institutions. Because of the multidisciplinary nature of Green Polymer Chemistry, corresponding publications tend to be spread out over numerous journals. This book brings these papers together so that the reader can gain a better appreciation of the breadth and depth of activities in Green Polymer Chemistry. It is based on contributions by oral and poster presenters at the international symposium, Biocatalysis in Polymer Science, held at the ACS National Meeting in Washington D.C. on August 17-20, 2009. Whereas many aspects of Green Polymer Chemistry were covered during the symposium, a particular emphasis was placed on biocatalysis and biobased materials. Many exciting new findings in basic research and applications were reported. In addition, several leaders in these areas who were unable to attend the symposium contributed important reviews of their ongoing work. As a result, this book provides a good representation of activities at the forefront of research in Green Polymer Chemistry emphasizing activities in biocatalysis and biobased chemistry. 24 cm.

Physical chemistry of polymer rheology / par Furukawa, Junji. Publication : [S.l.] : Springer, 2003 . 280 p. ; , Rheology is the science and technology that deals with the deformation of polymeric or plastic materials. In this monograph the field of polymer rheology is explained with emphasis on the chemical theory. The book provides basic information on rheology for nonspecialists and gives clear explanations of the various phenomena. The author has developed a new theory of thermodynamics and kinetics using a model of multi-size pseudo crosslinks that provides a comprehensive principle to show how links in chain molecules affect the melting temperatures and determine polymer properties such as viscoelasticity, melt viscosity and elastic and plastic behaviour of bulk polymers. The theory can be extended to include the strength of rubber and plastics, active fillers and adhesion, friction and abrasion. 24 cm.

Solid state nmr spectroscopy for biopolymers : principles and applications / par Saitʋ,, Hazime. Publication : [S.l.] : Springer, 2006 . 464 p. ; , When considering the biological significance and industrial and medical applications of biopolymers, it is crucial to know details of their secondary structure, dynamics and assembly. The biopolymers include globular, membrane and fibrous proteins, polypeptides, nucleic acids, polysaccharides and lipids. Solid state NMR spectroscopy has proved to be the most suitable and unrivaled means for investigations of biopolymers. The major advantage of solid state NMR spectroscopy is that the resulting line widths can be manipulated experimentally and are not influenced by motional fluctuation of proteins under consideration as a whole. Solid State NMR Spectroscopy for Biopolymers: Principles and Applications provides a comprehensive account on how the conformation and dynamics of such biopolymers can be revealed by solid state NMR spectroscopy. Special efforts have been made towards the historical and chronological consequences of a variety of applications and the dynamic aspects of the biopolymer system. In particular, the authors emphasise how important it is to record the most simple DD-MAS (one pulse excitation with high power decoupling) as a mean of locating very flexible portions of membrane proteins and membrane associated peptides. The authors also demonstrate that dynamic features of membrane proteins with a timescale of fast (10 8 Hz) and intermediate (10 4 -10 5 Hz) fluctuation motions can be revealed easily by specific suppression of peaks. 25 cm.
