This book was released on 2013-11-21 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.
Book Synopsis The Physics of Glassy Polymers by : R. N. Haward
Download or read book The Physics of Glassy Polymers written by R. N. Haward and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work sets out to provide an up-to-date account of the physical properties and structure of polymers in the glassy state. Properties measured above the glass transition temperature are therefore included only in so far as is necessary for the treatment of the glass transition process. This approach to the subject therefore excludes any detailed account of rubber elasticity or melt rheology or of the structure and conformation of the long chain molecule in solution, although knowledge derived from this field is assumed where required. Major emphasis is placed on structural and mechanical properties, although a number of other physical properties are included. Naturally the different authors contributing to the book write mainly from their own particular points of view and where there are several widely accepted theoretical approaches to a subject, these are sometimes provided in different chapters which will necessarily overlap to a significant extent. For example, the main theoretical presentation on the subject of glass transition is given in Chapter 1. This is supplemented by accounts of the free volume theory in Chapter 3 and in the Introduction, and a short account of the work of Gibbs and DiMarzio, also in Chapter 3. Similarly, there is material on solvent cracking in Chapters 7 and 9, though the two workers approach the subject from opposite directions. Every effort has therefore been made to encourage cross-referencing between different chapters.
Book Synopsis Surface Dynamics, Glass Transition, and Crystallization of Atactic Polystyrene by : Yu Chai
Download or read book Surface Dynamics, Glass Transition, and Crystallization of Atactic Polystyrene written by Yu Chai and published by . This book was released on 2016 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: How polymers behave near the glass transition is one of the deepest questions in condensed matter physics. In the past two decades, the surface dynamics, glass transition, and crystallization of polymer thin films have attracted much attention as they are not only scientific questions but also fundamentals of modern polymer industry. However, there are still many phenomena that are not clear, such as whether the glass transition is a real phase transition; whether there is an enhanced mobile layer near the free surface and how thick it is; whether the glass transition temperature reduction is caused by the free surface; whether some polymers cannot crystallize; etc. Here we try to gain insight into these questions. In this thesis, there are six chapters. The first chapter is introduction, in which some basic concepts and a literature review are presented. The second chapter contains the experimental details, in which the experimental techniques and data analysis methods are discussed. Chapter three, four, and five focus on three different research areas; however, these topics are related to each other. In chapter three, we conduct a novel stepped film levelling experiment to study the surface dynamics of polymer films near the glass transition temperature, in which several subtopics are involved, such as molecular weight dependent levelling, levelling under soft confinement, and ultra-thin films levelling. In chapter four, we find the direct evidence of the crystallization of atactic polystyrene, and systematically study the growth and melting kinetics of these crystals. In chapter five, the thermal expansivity of polystyrene thin films is measured using ellipsometry. These results confirm the validity of the recently proposed simple model, which connects the existence of an enhanced mobile layer near the free surface to the glass transition temperature reduction in thin films. The last chapter is concluding remarks and future work, in which a brief summary is included and some possible future studies are proposed.

Book Synopsis Dynamic Mechanical Properties of Solvent Crazed Polystyrene by : B. A. Shah
Download or read book Dynamic Mechanical Properties of Solvent Crazed Polystyrene written by B. A. Shah and published by . This book was released on 1976 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dynamic mechanical properties of polystyrene crazed in various organic solvents were determined on a Rheovibron Viscoelastometer. It was found that the loss curves for polystyrene crazed in the presence of ethylene glycol, diethylene glycol and triethylene glycol were similar to the uncrazed polystyrene. However, when 1-pentanol was used as the solvent, there is a substantial decrease in the glass transition temperature of polystyrene. The latter evidence is in clear agreement with the plasticization mechanism of solvent crazing. However, the former data with the glycols seem to indicate that the surface stabilization mechanism cannot be ruled out. (Author).
Book Synopsis Polymer Rheology: Theory and Practice by : Y.G. Yanovsky

This book was released on 2012-12-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present book is devoted to a rapidly developing field of science which studies the behavior of viscoelastic materials under the influence of deformation~the rheology of polymers. Rheology has long been treated as the theoretical foundation of polymer processing, and from this standpoint it is difficult to overesti mate its importance in practice. Rheology plays an important role in developing our ideas on the nature of viscoelastic behavior in connection with the structural features of polymers and composites based on them. This expands the possibilities of employing rheological methods to characterize a variety of materials and greatly magnifies the interest in this field of research. The rheological properties of polymer systems are studied experimen tally, chiefly under conditions of shear and tensile strains. One explana tion is that many aspects of polymer material processing are associated with the stretching of melts or a combination of shear and tensile strains. In scientific investigations, either periodic or continuous conditions of shear deformation are employed. Each mode provides widespread infor mation. In periodic deformation, most attention is generally given to conditions with low deformation amplitudes that do not alter the structure of the polymer system during an experiment (the region of linear deformation conditions). Here the viscoelastic parameters are generally determined with respect to the frequency. Continuous deforma tion involves considerable strains, and may be attended by significant reversible and irreversible changes in the structure of a polymer.

Book Synopsis Antioxidants in Science, Technology, Medicine and Nutrition by : G. Scott
Download or read book Antioxidants in Science, Technology, Medicine and Nutrition written by G. Scott and published by Elsevier. This book was released on 1997-05-01 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of antioxidants is widespread throughout the rubber, plastics, food, oil and pharmaceutical industries. This book brings together information generated from research in quite separate fields of biochemical science and technology, and integrates it on a basis of the common mechanisms of peroxidation and antioxidant action. It applies present knowledge of antioxidants to our understanding of their role in preventing and treating common diseases, including cardiovascular disease, cancer, rheumatoid arthritis, ischemia, pancreatitis, hemochromatosis, kwashiorkor, disorders of prematurity and disease of old age. Antioxidants deactivate certain harmful effects of free radicals in the human body due to biological peroxidation, and thus prevent protection against cell damage. The book is of considerable interest to scientists working in the materials and foodstuff industries, and to researchers seeking information on the connection between diet and health, and to those developing new drugs to combat diseases associated with oxidative stress. It is important also throughout the non-medical world, especially to the work force within the affected industries. Examines research in separate fields of biochemical science and technology and integrates it on a basis of the common mechanisms of peroxidation and antioxidant action Applies present knowledge of antioxidants to our understanding of their role in preventing and treating common diseases, including cardiovascular disease, cancer, rheumatoid arthritis and others
Book Synopsis Dielectric Properties of Polymers by : Frank Karasz
Download or read book Dielectric Properties of Polymers written by Frank Karasz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the electrical properties of polymers constitutes a substantial fraction of the total research interest in macro molecular behavior. Because of the increasing attention now being paid to theoretical and experimental aspects of the phenomena encountered, a symposium focusing particularly on dielectric behavior was held at the l6lst National Meeting of the American Chemical Society in Los Angeles, California, March, 1971. The authoritative papers in this volume were all presented at this symposium, which was sponsored by the Polymer Division of the American Chemical Society. An obvious advantage of such a collection is that it keep~ together closely related material which would otherwise tend to be dispersed amongst different journals; a further factor of which most authors represented here have taken advantage is that it gives an opportunity to present research in less attenuated form than is now normally possible in journals. I wish to thank all the authors for their uniformly excellent contributions and for their cooperation in the publication of this volume. Thanks are also due to Dr. S. Matsuoka for chairing one of the sessions at the symposium. September, 1971 Frank E. Karasz v LIST OF CONTRIBUTORS B.
