Download or read book Rotational Isomeric State Models in Macromolecular Systems written by Matthias Rehan and published by Springer. This book was released on 2006-05-09 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 40 years, RIS models for hundreds of polymer structures have been developed, and now the RIS approach is available in several software packages. However, users are often faced with the time-consuming task of finding the appropriate RIS parameters among the literature. This book facilitates this task by providing a comprehensive overview of the models available. It reviews the literature from the very first applications to the end of 1994, comprises synthetic as well as naturally occuring macromolecules, and tabulates all the pertinent features of published models. It will thus help readers, even those new to this method, to take advantage of this computationally efficient way of assessing the conformational properties of macromolecular systems.
Download or read book Structure and Properties of Ionomers written by Michel Pineri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ionomers, that is polymers containing a low concentration of charged units along the chain, have been the subject of increasing interest during the past twenty years. The presence of ionic groups in the poly mer changes some of its properties dramatically. Increases in the modu lus and the viscosity of several orders of magnitude have been observed, and changes in the glass transition of hundreds of degrees are possible. In addition, diffusion coefficients can be modified drastically. These changes are due primarily to the presence of reversible ionic cross links in these materials. Because of the low dielectric constant of most organic polymers, the ions or ionic dipoles tend to aggregate ; this aggregation process, however, is limited, because the ionic groups are covalently bonded to the organic chain. Host of the fundamental research done on these materials has been devoted to a determination of the extent of association, the structure of the aggregates, the limi ting factors, and the correlations between molecular and supermolecular structure and the resul ting properties.

Download or read book Structure and Dynamics of Strongly Interacting Colloids and Supramolecular Aggregates in Solution written by Sow-Hsin Chen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 848 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, various powerful experimental tools have been developed, such as small angle X-ray and neutron scattering, X-ray and neutron reflection from interfaces, neutron spin-echo spectroscopy and quasi-elastic multiple light scattering and large scale computer simulations. Due to the rapid progress brought about by these techniques, one witnesses a resurgence of interest in the physicochemical properties of colloids, surfactants and macromolecules in solution. Although these disciplines have a long history, they are at present rapidly transforming into a new, interdisciplinary research area generally known as complex liquids or soft condensed matter physics: names that reflect the considerable involvement of the chemical and condensed matter physicists. This book is based on lectures given at a NATO ASI held in the summer of 1991 and discusses these new developments, both in theory and experiment. It constitutes the most up-to-date and comprehensive summary of the entire field.

Available in PDF, EPUB and Kindle. Book excerpt: The papers in this volume were presented at the 1991 London International Chlorine Symposium held at the intercontinental Hotel from 5th-7th June. This was the sixth symposium in a series organized by the Electrochemical Technology Group of the SCI and held in London at intervals of three years. A continued high level of interest in the proceedings was demonstrated by offers of 40 papers, and of these 26 were selected for inclusion in the programme. The conference intention was to reflect the developments in chlorine technology hardware and software and to address the economic, political, environmental and safety issues which are increasingly impacting on the chlorine industry as the millennium approaches. In the event the five sessions were broadly based on the following topic areas: Chlorine and the Environment Membranes 1 Membranes 2 Chlorine Safety Electrodes/Electrode Reactions Not unexpectedly, the importance of membrane technology to the industry was reflected by the inclusion of 9 papers. However, the traditional diaphragm, mercury and chlorate cell technologies were also represented. The academic base of the organizing body was underlined by the selection of papers from the Universities of Milan and Calgary, and by the opening and closing remarks of the Chairman of the SCI Electrochemical Technology Group, Frank Goodridge, Professor Emeritus of Newcastle University. The opportunity was taken to present the SCI Castner Medal to Dr H. Miyake of Asahi Glass Co. Ltd for his work on the design and development of Flemion electrodes.

Download or read book Multinuclear NMR of Ionomers and Polymer Blends written by Ellen Margaret O'Connell and published by . This book was released on 1995 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many factors are known to affect the morphology and properties of ionomers, and the role that the cation local environment plays is not well understood. To better understand ionomer morphology, the cation environment in sulfonated and carboxylated ionomers was investigated using 23Na NMR. As many as three environments were seen in polydisperse sulfonated polystyrene (NaSPS): isolated sodium ions at 7 ppm, hydrated ions at 0 ppm, and aggregated ions at -12 to -23 ppm. In monodisperse NaSPS, a fourth peak at -2.7 ppm appeared at ionization levels above 1.2% and molecular weights of at least 35,000. The fraction of sodium ions held in isolated ion pairs decreased to zero while the fraction of ionic species in aggregates increased with increasing sulfonation. As the neutralization level increased, the aggregate peak shifted to higher frequency with incorporation of neutralizing NaOH. These peak positions and trends are explainable in terms of the magnetic and electric field properties of each Na+ environment.
Download or read book Molecular and Cellular Biophysics written by Jack A. Tuszynski and published by CRC Press. This book was released on 2018-10-24 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: From quantum theory to statistical mechanics, the methodologies of physics are often used to explain some of life's most complex biological problems. Exploring this challenging yet fascinating area of study, Molecular and Cellular Biophysics covers both molecular and cellular structures as well as the biophysical processes that occur in these structures. Designed for advanced undergraduate and beginning graduate students in biophysics courses, this textbook features a quantitative approach that avoids being too abstract in its presentation. Logically organized from small-scale (molecular) to large-scale (cellular) systems, the text first defines life, discussing the scientific controversies between mechanists and vitalists, the characteristics of living things, and the evolution of life. It then delves into molecular structures, including nucleic acids, DNA, RNA, interatomic interactions, and hydrogen bonds. After looking at these smaller systems, the author probes the larger cellular structures. He examines the cytoplasm, the cytoskeleton, chromosomes, mitochondria, motor proteins, and more. The book concludes with discussions on biophysical processes, including oxidative phosphorylation, diffusion, bioenergetics, conformational transitions in proteins, vesicle transport, subcellular structure formation, and cell division.
