The second edition of this textbook is identical with its fourth German edi tion and it thus has the same goals: precise definition of basic phenomena, a broad survey of the whole field, integrated representation of chemistry, physics, and technology, and a balanced treatment of facts and comprehen sion. The book thus intends to bridge the gap between the often oversimpli fied introductory textbooks and the highly specialized texts and monographs that cover only parts of macromolecular science. The text intends to survey the whole field of macromolecular science. Its organization results from the following considerations. The chemical structure of macromolecular compounds should be inde pendent of the method of synthesis, at least in the ideal case. Part I is thus concerned with the chemical and physical structure of polymers. Properties depend on structure. Solution properties are thus discussed in Part 11, solid state properties in Part Ill. There are other reasons for dis cussing properties before synthesis: For example, it is difficult to understand equilibrium polymerization without knowledge of solution thermodynamics, the gel effect without knowledge of the glass transition temperature, etc. Part IV treats the principles of macromolecular syntheses and reactions."

Ever since the first volume appeared in 1969, this series has received good reviews in a variety of periodicals published in different corners of 'the world. It would seem that the work has fulfilled its purpose as outlined in the Preface to Volume 1. The rapidly increasing interest in surface and colloid science by people engaged in industrial research and development, and in environmental, ecological, medical, pharmaceutical, and other areas, justifies the continuation of such an effort. After nine volumes with John Wiley and Sons, this and subsequent volumes will-by mutual consent-be published by Plenum Press. The editor will do his best to maintain and, if possible, improve the quality of the contributions. While the fundamental philosophy will be preserved, some moderate graphical changes have taken place. These changes were done to enhance the readability and uniformity of the volumes. Occasionally, volumes may appear under the editorship of other scientists in the field. These volumes will be mainly devoted to techniques in surface and colloid science. For reasons of continuity a sequential numbering system will be used.

The chemistry of transition metal carbyne complexes has become a highly attractive field during the past twenty years. In recent years its application to aspects of catalysis and metathesis has gained considerable interest from inorganic as well as organic chemists. In addition, organic synthesis by means of metal carbon multiple bond reagents offers the most sophisticated technology currently available. In consideration of these developments some of Professor E. O. Fischer's former coworkers and colleagues felt obliged to orga nize this NATO Advanced Research Workshop on Transition Metal Carbyne Complexes in the Bavarian Alps. They have been encouraged by the fact that most of the distinguished scientists in the field of metal-carbon multiple bond chemistry had finally agreed to participate and to present stimulating lectures. The organizers of the workshop are deeply grateful to the Scientific Affairs Division of the NATO for the generous financial support of the meeting in Wildbad Kreuth and for the preparation of this book. They also feel indebted to acknowledge the generous support from Wacker-Chemie, BASF, Peroxid-Chemie, Hoechst and Bayer. Finally they thank the staff of the Hanns-Seidel-Stiftung in Wildbad Kreuth for providing a pleasant and stimu lating atmosphere during the meeting."

This volume is comprised of most of the papers presented at a symposium held in Miami Beach during the national meeting of the American Chemical Society in September, 1978. In a sense, it is a sequel to the first ACS symposium held on this topic and published under the title "Polymer Colloids" in 1971 by Plenum Press. That volume contained 12 papers, whereas "Polymer Colloids II" contains 33, an indication of the magnitude of the growth of the field in less than a decade. Increased sophistication probably best characterizes the changes which have taken place, especially in the realm of instru mentation. Ten years ago techniques such as quasielastic light scattering, X-ray photoelectron spectroscopy (XPS - also known as ESCA), ion scattering spectroscopy (ISS), ultrasonic absorption spectroscopy and hydrodynamic exclusion chromatography (REC) were unavailable to the polymer colloid chemist. Recent advances in all of these methods are described in this volume. Although the book deals primarily with "synthetic latexes" or "emulsion polymers" as colloids, there are a number of papers which deal with their synthesis: particle nucleation in emulsion polymer ization, the synthesis of emulsifier-free polymer colloids using novel reagents, molecular weight distributions derived from the kinetics of emulsion polymerization, and anionically polymerized non-aqueous polymer colloids. The kinetics and thermodynamics of the swelling of latex particles by monomers is also dealt with here."

The past decade has witnessed a vigorous growth in activities toward the development of a variety of biomedical devices ranging from the simple A-V shunt to the complex artificial heart. Re search and development teams have been created comprising engi neers, material scientists and clinicians and, perhaps for the first time, such groups are collaboratively bringing their respec tive talents to bear on problems associated with defects in the human organism. These collaborations have resulted in a prolifera tion of new information and a rapid and continuing redefinition of the frontiers of progress. It was to keep pace with these changes, and provide an updated view of the state of the art that this meeting was conceived. The present volume marks the publication of the proceedings of the Johnson & Johnson Symposium held in Morristown, New Jersey, on July 11 and 12, 1974. It surveys the applications of polymers to medical and surgical problems and contains discus sions on the biocompatibility of polymers, polymers as biomate rials, and the use of polymers in prosthetic devices and drug re lease systems. In addition, the Symposium offers recent perspec tives on the critical problems of the material-tissue interface, the design criteria for silicone-based systems, and the varied use of polymers in artificial hearts, kidneys, eyes and lungs."

The last decade or so has seen a dramatic increase in the amount of detailed structural information available from a range of experimental techniques. Exciting new techniques such as atomic force microscopy have become widely available, while the potential of established methods like X-ray diffraction and electron microscopy has been greatly enhanced by powerful new sources and analytical methods. Progress in computing has also had a widespread impact: in areas such as neutron scattering, large data sets can now be manipulated more readily. The software supplied with commercial instruments generally provides more sophisti cated analytical facilities, while time-resolved X-ray studies rely on rapid data handling capabilities. The polymer scientist is faced with an expanding array of experimental tools for addressing both fundamental science and industrial problems. This work reviews some recent developments in structural techniques, with the aim of presenting the current 'state of the art' in a selection of areas."

Targeting of drugs via carrier systems to sites in the body in need of pharmacologic intervention is a rapidly growing area of research in the treatment or prevention of disease. It has evolved from the need to preferentially deliver drugs, enzymes, vitamins, hormones, antigens, etc. to target cells and organs so as to avoid toxicity, waste of drugs through premature secretion or inactivation and at the same time render treatment more convenient and cost-effective. A wide assortment of naturally occ urring or semi-synthetic drug carriers (e. g. antibodies, glycoproteins, lectins, peptide hormones, cells and liposomes), their inter action with relevant receptors and mediation of optimal pharmacological action were discussed in the two previous NATO Advanced Studies Institutes (ASI) of this series, "Targeting of Drugs" and "Receptor-Mediated Targeting of Drugs," the proceedings of wh ich were published by Plenum in 1982 and 1984 respectively. This book contains the proceedings of the 3rd NATO ASI "Targeting of Drugs with Synthetic Systems" held as be fore at Cape Sounion, Greece during 24 June-5 July 1985. It deals mostly with man-made carriers such as a variety of polymers, matrices, liposomes and other colloidal micro particles. The twenty chapters discuss the interaction of such carriers with the biological milieu, approaches to bypass the reticuloendothelial system (or, when needed, take advantage of its interception of carriers to optimally deliver drugs to phagocytes) and ways to improve delivery to specific cells, often with the help of carrier-linked ligands."

This volume documents the proceedings of the Second Symposium on Metallized Plastics: Fundamental and Applied Aspects held under the aegis of the Dielectric Science and Technology Division of the Electrochemical Society in Montreal, Canada, May 7-10, 1990. The first symposium on this topic was held in Chicago, October 10-12, 1988 and the proceedings of l which have been chronicled in a hard-bound volume l As pointed out in the Preface to the proceedings of the first symposium the metallized plastics find scores of applications ranging from very mundane to very sophisticated. Even a cursory look at the literature will convince that this field has sprouted; and there is every reason to believe that with all the research and development activities taking place, new and exciting applications of metallized plastics will emerge. The program for the second symposium was very comprehensive as it included 46 papers covering many aspects of metallized plastics. This symposium was a testimonial to the brisk research activity and keen interest in the topic of metallized plastics. The success of this symposium reinforced our earlier belief that there was a definite need to hold symposia on this topic on a regular basis. Concomitantly, the third symposium in this vein was held in Phoenix, Arizona, October 13-18, 1991 and the fourth is planned for May 16-21, 1993 in Honolulu, Hawaii. As regards the present volume, it contains a total of 35 papers covering a variety of topics ranging from very fundamental to very applied.

In the early 1980s capillary liquid chromatography was being established; it was a period in which only a few research groups published a relatively small number of papers on the subject. In terest has since taken off, and a period of intense development, to which no end is yet in sight, is now upon us. More investiga tors and instrument-making firms are now entering the field. This greater interest has resulted in the rapid appearance of two collec tions [1, 2] and a series of topical reviews [3-6]. However, it could hardly be said that all the problems in this area have been formulated, let alone solved. The preparation of very efficient - open tubular or packed - microbore columns, for example, remains more an art than a science, while the relation ship between radial and longitudinal mass transfer, and the effect of transcolumn velocity profiles on chromatographic efficiency, have been very poorly studied. Indeed, recent publications on these subjects have sometimes, far from clarifying matters, only muddied them further. Many instrument-making firms are trying to unify their equip ment so that it is suitable for microbore, conventional (analytical), and preparative liquid chromatography. This approach has not real ized the full potential of capillary chromatography, and there also remains room for improving the performance of capillary columns.

The basis for this volume is the 11th Symposium on Analytical Ultracentrifugation held in March 25-26, 1999 at the University of Potsdam, Germany. This book presents a comprehensive collection of 33 contributions from leading scientists in this field including:
Technical and methodological innovations.- Innovations in data analysis.- Hydrodynamics/Modelling.- Synthetic polymers, colloids and supramolecular systems.- Biological systems.- Interacting systems and assemblies.
In contrast to the increasing significance of analytical ultracentrifugation, related modern books are very rare. Therefore, this volume will be a helpful source of information to anyone who wants to catch up with the most recent developments and results related to this important analytical method.

Gellan gum, a microbial polysaccharide, consisting of tetra-saccharide unit, glucose, glucuronic acid, glucose and rhamnose, forms a transparent gel which is heat-resistant in the presence of divalent cations. Since 1989, the collaborative research group was organised in the Research Group of Polymer Gels affiliated to the Society of Polymer Science, Japan, consisting of various laboratories with different disciplines to clarify the mechanism using the common purified sample. This special issue contains 19 papers on the molecular conformation, gel-sol transition, interaction of gellan and water, cations and sugar, based on rheology, NMR, ESR, DSC, light scattering, osmotic pressure, small angle x-ray scattering, dielectric measurement, atomic force microscopy and the industrial application of gellan gum presented at the 4th International Conference on Hydrocolloids - OCUIS '98 by the collaborative group members and by international experts.

This volume "Deformation of Ceramic Materials II" constitutes the proceedings of an international symposium held at The Pennsyl vania State University, University Park, PA on July 20, 21, and 22, 1983. It includes studies of semiconductors and minerals which are closely related to ceramic materials. The initial conference on this topic was held in 1974 at Penn State and the proceedings were published in the volume entitled "Deformation of Ceramic Materials." This conference emphasized the deformation behavior of crystals and po1ycrysta11ine and polyphase ceramics with internationally recognized authorities as keynote lecturers on the major subtopics. Several papers dealing with cavity nucleation and creep crack growth represent a major new research thrust in ceramics since the first conference. This collection of papers represents the state-of-the art of our understanding of the plastic deformation behavior of ceramics and the crystals of which they are composed. We are grateful for the suggestions of our International Advisory Committee .in recommending experts in their respective countries to participate. We are particularly grateful that the organizers of the previous Dislocation-Point Defect Interaction Workshops agreed to participate in the Penn State Symposium as an alternative at the suggestion of Prof. A. H. Heuer. We acknowledge the financial support of the National Science Foundation for this conference."
