The liquid crystalline state may be identified as a distinct and unique state of matter which is characterised by properties which resembles those of both solids and liquids. It was first recognised in the middle of the last century through the study of nerve myelin and derivatives of cholesterol. The research in the area really gathered momentum, however, when as a result of the pioneering work of Gray in the early 1970's organic compounds showing liquid crystalline properties were shown to be suitable to form the basis of display devices in the electronic products. The study of liquid crystals is truly multidisciplinary and has attached the attention of physicists, biologists, chemists, mathematicians and electronics engineers. It is therefore impossible to cover all these aspects fully in two small volumes and therefore it was decided in view of the overall title of the series to concentrate on the structural and bonding aspects of the subject. The Chapters presented in these two volumes have been organised to cover the following fundamental aspects of the subject. The calculation of the structures of liquid crystals, an account of their dynamical properties and a discussion of computer simulations of liquid crystalline phases formed by Gay Berne mesogens. The relationships between molecular conformation and packing are analysed in some detail. The crystal structures of liquid crystal mesogens and the importance of their X ray scattering properties for characterisational purposes are discussed.

The Fifth Chinese Peptide Symposium, hosted by Lanzhou University, was held at Lanzhou, China July 14-17, 1998, with 156 participants, including 30 scientists from abroad, representing nine countries. The four-day conference was both intense and spiritually rewarding. Our goal for CPS-98 was to provide a forum for the exchange of knowledge, cooperation and friendship between the international and Chinese scientific communities, and we believe this goal was met. The symposium consisted of 8 sessions with 42 oral and 90 poster presentations, including synthetic methods, molecular diversity and peptide libraries, structure and conformation of peptides and proteins, bioactive peptides, peptide immunology, De Novo design and synthesis of proteins and peptides, ligand-receptor interactions, the chemistry-biology-interface and challenging problems in peptides. The enthusiastic cooperation and excellent contributions were gratifying and the active response of the invited speakers contributed to the success of the symposium. The presentations were of excellent caliber and represented the most current and significant aspects of peptide science. Dr. Kit Lam of the University of Arizona and Dr. Yun-Hua Ye of Peking University were the recipients of "The Cathay Award" sponsored by the H. H. Liu Education Foundation, offered for their seminal contribution in peptide science and the Chinese Peptide Symposium. Four outstanding young scientists were selected by the organizing committee to receive awards sponsored by Haikou Nanhai Pharmaceutical Industry Co. Ltd. (Zhong He Group).

Holographic Interferometry provides a valuable and up-to-date source of information in the rapidly expanding field. The eight specialists` contributions cover the principles and methods currently in use. The scope of the book has been limited to the study of opaque object and ample space has been devoted to a comprehensive treatment of the phenomena of fringe formation, with a particular emphasis on the quantitative evaluation of the holographic interference fringe patterns. The emergence of computer-aided fringe analysis and phase-shifting techniques have simplified considerably the quantative real-time measurements of object shapes and deformations. The last two chapters provide a reasonably detailedoverview of full-field holographic methods for the measurement of shapes, displacements, dervatives, difference displacements and vibrations.

This book is derived from a Symposium held at the 190th National American Chemical Society Meeting, which was held in the Fall of 1985, in Chicago, and was sponsored by the Division of Polymeric Materials: Science & Engineering. This Symposium was, in turn, a follow-up on an earlier one held in Houston, TX, in the Spring of 1980, which was pub lished as the book *Biomedical and Dental Applications of Polymers* [Plenum Press, New York, 1981]. In that earlier book, our opening Preface passage quoted King David, *1 will praise Thee; for I am fearfully and made . ** * (Psalm 139:14). As we noted five years ago, sickness wonderfully of many types does occur in our wonderfully made bodies, but much human suffering can be aided by biomedical polymers. That earlier book con sidered much of the fantastic progress that had been made in biomedical polymers during the previous quarter century and brought many of these topics up to date. That Symposium, and book, noted that much help was available for the varied afflictions and problems that sometimes beset, and upset, our God-given bodies, and the promise of new and important advances was held out as a shining ray of hope amidst the gloom of sickness and affliction. The present volume is an update on the advances that have occurred since the 1981 book and sets the stage for even greater advances in the future.

Natural products like wool, leather or cotton are permeable to water vapor. Their complex fibrous structure makes it difficult to imitate this natural phenomenon by synthesis. This book discusses ways to obtain water vapor permeability by microporosity or through a hydrophilic structure. Various areas of application include the medical sector for implants and dialysis, the industrial sector for filtration or for processes requiring the slow release of substances, and the consumer sector for leather substitutes or performance textiles.

In a liquid crystal watch, the molecules contained within a thin film of the screen are reorientated each second by extremely weak electrical signals. Here is a fine example of soft matter: molecular systems giving a strong response to a very weak command signal. They can be found almost everywhere. Soft magnetic materials used in transformers exhibit a strong magnetic moment under the action of a weak magnetic field. Take a completely different domain: gelatin, formed from col lagen fibres dissolved in hot water. When we cool below 37 DegreesC, gelation occurs, the chains joining up at various points to form a loose and highly deformable network. This is a natural example of soft matter. Going further, rather than consider a whole network, we could take a single chain of flexible polymer, such as polyoxyethylene [POE = (CH CH O)N, 2 2 5 where N rv 10 ], for example, in water. Such a chain is fragile and may break under flow. Even though hydrodynamic forces are very weak on the molecular scale, their cumulated effect may be significant. Think of a rope pulled from both ends by two groups of children. Even if each girl and boy cannot pull very hard, the rope can be broken when there are enough children pulling.

The investigative assault upon the enigmatic asphaltenes has recently resulted in sig nificant advances in many varied disciplines. Taken individually, each discipline exposes certain facets of asphaltenes, but each, alone, can never reveal asphaltenes from all van tages. Even seemingly narrowly focused issues such as the molecular structures of asphal tenes, or the colloidal structures of asphaltenes require a confluence of many lines of investigation to yield an understanding which differs from truth by diminishing uncer tainty. An holistic treatment of the asphaltenes is a powerful approach to evolve further their understanding. For example, examination of asphaltenes at the highest resolution yields molecular structure. A slight increase in scale probes asphaltene colloidal structure. Weaving together asphaltene studies performed at different length scales results in a fabric which envelops an encompassing vision of asphaltenes. At the same time, the interfaces of these hierarchical studies provide additional constraints on imagination, more than investi gations at individual length scales alone. These considerations shaped the timing, format, and the content of our book. The editors are very appreciative of the diligence and hard work manifest in each of the contributed chapters herein. We thank the contributing authors for making this project a success. Oliver C. Mullins Eric Y. Sheu vii CONTENTS I. Asphaltenes: Types and Sources ...................................... ."

The role of high pressure experiments in the discovery of supercon ducting materials with a T. above liquid nitrogen temperature has demon strated the importance of such experiments. The same role holds true in the tailoring of materials for optoelectronic devices. In addition, much progress has been made recently in the search for metallic hydro gen, and the application of high pressure in polymer research has brought forth interesting results. These facts together with the suc cess of previous small size meetings (such as the "First International Conference on the Physics of Solids at High Pressure", held in 1965 in Tucson, Arizona, U. S. A. ; "High Pressure and Low Temperature Physics", held in 1977 in Cleveland, Ohio, U. S. A. ; and "Physics of Solids Under High Pressure", held in 1981 in bad Honnef, Germany), motivated us to organize a workshop with emphasis on the newest results and trends in these fields of high pressure research. Furthermore, it was intended to mix experienced and young scien tists to realize an idea best expressed in a letter by Prof. Weinstein: "I think it is an excellent idea. I have often felt that the number of excellent young researchers in the high pressure field need an opportu nity to put forward their work with due recognition. " Thanks to the support of the key speakers, we were able to achieve this goal and had more than 50\ young participants.

Many chemical processes that are important to society take place at boundaries between phases. Understanding these processes is critical in order for them to be subject to human control. The building of theoretical or computational models of them puts them into a theoretical framework in terms of which the behavior of the system can be understood on a detailed level. Theoretical and computational models are often capable of giving descriptions of interfacial phenomena that are more detailed, on a molecular level, than can be obtained through experimental observation. Advances in computer hardware have also made possible the treatment of larger and chemically more interesting systems. The study of interfacial phenomena is a multi-disciplinary endeavor which requires collaboration and communication among researchers in different fields and across different types of institutions. Because there are many important problems in this field much effort is being expended to understand these processes by industrial laboratories as well as by groups at universities. Our conference titled "Theoretical and Computational Approaches to Interface Phenomena" held at South Dakota State University, August 2-4, 1993 brought together over thirty scientists from industry and academia and three countries in the western hemisphere to discuss the modeling of interfacial phenomena.

The art and science of macromolecular architecture is based on synthesis, analysis, processing, and evaluation of physical properties of polymers. The growing specificity of available synthetic methods and the increasing refinement of analytical and physical analysis are gradually providing a deeper insight into structure-property relationships of polymers, upon which many applications can be based. This book deals with recent methods for polymer synthesis. Those that lead to specific structures have been selected especially. Background, mechanism scope and limitations, and illustrative procedures are given for each method. With this layout the editor hopes that the book will provide a practical guideline, for the synthetic polymer chemist in industry or at a university graduate school, on how to apply the methods in the design of new polymer structures. The editor is grateful to the authors not only for their contributions containing interesting new developments in polymer synthesis, but also for the way they have fitted their text into the general framework of the book. The elegant chemistry described in the following chapters will, it is hoped, inspire more organic chemists to apply their skills to polymer synthesis, where the beauty of organic chemistry in terms of structural control and reactivity may be even more apparent than in the low molecular field.

The idea for this book came from discussions among participants in a symposium on biotechnical applications at the "Pacifichem 89" meeting in Honolulu. It was the majority opinion of this group that a volume dedicated to biotechnical and biomedical applications of PEG chemistry would enhance research and development in this area. Though the book was conceived at the Honolulu meeting, it is not a proceedings of this symposium. Several groups who did not participate in this meeting are repre sented in the book, and the book incorporates much work done after the meeting. The book does not include contributions in all related areas to which PEG chemistry has been applied. Several invited researchers declined to parti.:ipate, and there is not enough space in this single volume to properly cover all submissions. Chapter I-an overview of the topic-discusses in brief applications not given detailed coverage in specifically devoted chapters. The following topics are covered: introduction to and fundamental properties of PEG and derivatives in Chapters 1-3; separations using aqueous polymer two-phase partitioning in Chapters 4-6; PEG-proteins as catalysts in biotechnical applications in Chapters 7 and 8; biomedical applications of PEG-proteins in Chapters 9-13; PEG modified surfaces for a variety of biomedical and biotechnical applications in Chapters 14-20; and synthesis of new PEG derivatives in Chapters 21 and 22.
