Ordering in Macromolecular Systems


Book Description

This volume summarizes the papers presented at the First Osaka University Macromolecular Symposium OUMS'93 on "Ordering in Macromolecular Systems", which was held at Senri Life Science Center, Osaka, Japan, on June 3 through June 6, 1993. The symposium covered the three topics, (1) Crystallization and Phase Transitions, (2) Polymer Liquid Crystals and (3) Block Copolymers, Polymer Blends and Surfaces, and invited leading scientists in these fields. At present any of these topics is a hot issue in itself and frequently taken up separately in many occasions. It is noted however that all these topics are correlated with each other with the keyword "Ordering" and their combination provides a unique feature of the present symposium in reflecting the interactions among investigators working in these important fields with the common ground expressed by the keyword "Ordering". Nineteen invited lectures and 40 posters of both experiment and theory were presented at the symposium, and the eighteen lectures and ten poster presentations contribute to this volume. In the first topic crystal structures and their transitions were discussed from kinetic as well as static points of view; attention was paid to give a molecular-level interpretation of the structure, phase transition and physical properties, using theories and simulations. The second topic was mainly concerned with static structures and thermodynamic properties of polymer liquid crystals including phase behaviours.




Spectroscopy of Partially Ordered Macromolecular Systems


Book Description

The papers in the volume tackle most important aspects of examining partial order, either natural or induced by mechanical or chemical treatment of the system and cover a wide variety of experimental and theoretical methods such as NMR and Raman spectroscopy.




Water and Biological Macromolecules


Book Description

Water and Biological Macromolecules presents an excellent description of the structural aspects of water molecules around biological macromolecules. Topics discussed include the properties of water in solid and liquid states; proteins, nucleic acids, polysaccharides, and lipids; and theoretical approaches for understanding the macroscopic observations and integrating microscopic descriptions. The nature and roles of hydration forces in macromolecular complexation and cell-cell interactions are explained, in addition to phenomena such as entropy-enthalpy compensation and the thermodynamic treatment of water bridging. Water and Biological Macromolecules will be a valuable reference for biophysicists, biochemists, and macromolecular biologists.




NMR of Ordered Liquids


Book Description

NMR of Ordered Liquids gives a unique overview of the scope and limitations of the NMR of oriented liquids, based on contributions from acknowledged experts in the field. The book consists of four sections: -detailed general introduction which covers the basic principles and sophisticated experimental techniques; -wide variety of applications ranging from NMR studies of small atoms and molecules in anisotropic liquids to the utilization of residual dipolar couplings for structure determination of biological molecules; -summary of the sophisticated theoretical treatments, computer simulations, and phenomenological models for anisotropic intermolecular interactions that are widely used in the analysis of experimental results; -overview of the dynamical aspects and relaxation processes relevant for orientationally ordered molecules.




Rotational Isomeric State Models in Macromolecular Systems


Book Description

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.




Dynamics of Ordering Processes in Condensed Matter


Book Description

The International Symposium on Dynamics of Ordering Processes in Condensed Matter was held at the Kansai Seminar House, Kyoto, for four days, from 27 to 30 August 1987, under the auspices of the Physical Soci ety of Japan. The symposium was financially supported by the four orga nizations and 45 companies listed on other pages in this volume. We are very grateful to all of them and particularly to the greatest sponsor, the Commemorative Association for the Japan World Exposition 1970. A total Df 22 invited lectures and 48 poster presentations were given and 110 participants attended from seven nations. An objective of the Symposium was to review and extend our present understanding of the dynamics of ordering processes in condensed matters, (for example, alloys, polymers and fluids), that are brought to an un stable state by sudden change of such external parameters as temperature and pressure. A second objective, no less important, was to identify new fields of science that might be investigated by similar, but sometimes more sophisticated, concepts and tactics. An emphasis was laid on those universal aspects of the laws governing the ordering processes which transcended the detailed differences among the substances used. The 71 lectures reproduced in this volume bear witness to the success of the Symposium in meeting amply the first objective and, to a lesser extent, the second.

Liquid Crystalline Order in Polymers


Book Description

Liquid Crystalline Order in Polymers examines the topic of liquid crystalline order in systems containing rigid synthetic macromolecular chains. Each chapter of the book provides a review of one important area of the field. Chapter 1 discusses scattering in polymer systems with liquid crystalline order. It also introduces the field of liquid crystals. Chapter 2 treats the origin of liquid crystalline order in macromolecules by describing the in-depth study of conformation of such macromolecules in their unassociated state. The chapters that follow describe successively the liquid crystalline order in polymers with mesogenic side groups and rigid backbones, in polypeptides, and in block copolymers. Chapter 7 discusses the rheology of such systems. The last two chapters examine liquid crystalline order in biological materials and mesomorphic order in the realm of polymers with inorganic backbones. This book is intended to provide the polymer scientist, the materials scientist, and the biologist with a valuable source of information.




Solitons in Macromolecular Systems


Book Description

This book addresses the issue of non-linear problems that have dominated the forefront of physics. To analyse these problems, it is necessary to develop mathematical methods to match new concepts. In this connection, for the first time in a long time, the same key notions have attracted the attention of physicists and mathematicians. This book discusses how the role of such excitations in essentially non-linear systems is similar to that of harmonic oscillations and waves in linear physical models.




Oral Delivery of Macromolecular Drugs


Book Description

Recent and rapid progress in the field of biotechnology has resulted in an increasing number of novel macromolecular drugs with great promise for further advanced research and clinical application. However, the delivery of these macromolecular drugs by routes other than the parenteral route is difficult. The pipeline of macromolecular drugs derived from biotechnology presents a challenging opportunity to develop practical dosage forms that could be dosed via the oral route. Given this, the successful oral delivery of macromolecular drugs presents an enormous opportunity. Oral Delivery of Macromolecular Drugs will provide an overview of the innovative oral delivery technologies that have demonstrated success in human testing and will go on to cite the challenges, strategies, and future trends that are to be expected.
