Crystallisable polymers represent a large share of the polymers used for manufacturing a wide variety of objects, and consequently have received continuous attention from scientists these past 60 years. Molecular compounds from crystallisable polymers, particularly from synthetic polymers, are receiving growing interest due to their potential application in the making of new materials such as multiporous membranes capable of capturing large particles as well as small pollutant molecules. Polymer-Solvent Molecular Compounds gives a detailed description of these promising systems. The first chapter is devoted to the presentation of important investigational techniques and some theoretical approaches. The second chapter is devoted to biopolymers, the first polymers known to produce molecular compounds, chiefly with water. The third chapter deals with synthetic polymers where compound formation is either due to hydrogen-bonding or to electrostatic interactions. The fourth chapter describes intercalates and clathrates systems for which compound formation is mainly due to a molecular recognition process. First book on the subject Gives a short but exhaustive description of investigational tools Covers both biopolymers and synthetic polymers Uses temperature-concentration phase diagrams abundantly for describing the systems Describes systems from the nano to the microscopic level, including mechanical properties

The main goal of this book is to describe the synthesis and properties of low and high-molecular compounds on the quantitative level. Special attention was given to composition materials based on polymers and dispersed wood, the mechanism of HCL elimination reactions via a four-centre transition state during PVC thermal destruction, swelling of the filled polymer compositions, structure and properties of combined systems based on butadiene-nitrile and ternary ethylene-propylene elastomers, intensification mass transfer processes in fast liquid-phase chemical reactions, the examples of hetero-nanophase kinetic description of photochemical reactions, the nanometric particle-like local structures and their implications in polymer behaviour, fractal physical chemistry of polymer solutions, modification of polycyanurates by polyethers, polyesters and polyurethanes, hybrid and interpenetrating polymer networks. This collection includes articles devoted to production of polymers, polymeric mixtures, composite and filled polymers, questions of expanding lifetime of polymeric articles, biologically active substances, modification of polymers and polymer-analogous transformations, fractal physical chemistry of polymer solutions, the study of structural transformations in polymers and some other questions. Of special attention are also production of pure substances and protection of the environment.

The NATO Advanced Research Workshop "Role of Interfaces in Environmental Protection" has been held on May 27-30, 2002 in Miskolc, Hungary, under leadership of co-directors Prof Sandor Barany from the University ofMiskolc, Hungary, and Prof Nataliya Klymenko, National Academy of Sciences of Ukraine. The objective of the ARW was to highlight colloidal and biocolloidal aspects of environmental pollution and technologies to monitor, remediate, abate and prevent pollution. It is known that the solution of majority of environmental problems is closely connected with phenomena at the interfaces. The behaviour, transport of dispersed particles in the environment, the main phase separation methods in water treatment, purification of liquids, aerosols removal, many soil remediation processes as well as the methods of protection of human organisms from hazardous matters, are based on concepts of colloid chemistry, i.e. properties of interfaces and their behaviour in different media. Examples of these methods are: filtration, ultrafiltration, flotation, coagulation, hetero-coagulation and flocculation, adsorption, adhesion of micro-organisms to surfaces, membrane separation methods, etc. A very important and special aspect of the topic is the human protection using colloid-chemical approaches, i.e. the adsorption, aggregation and adagulation properties of differe~t materials. Examples are: adsorption of hazardous organic materials, drugs, heavy· metals and radionuclides on activated carbon, silica, cellulose derivatives, etc.

les Houches This Winter School on "The Physics and Fabrication of Microstructures" originated with a European industrial decision to investigate in some detail the potential of custom-designed microstructures for new devices. Beginning in 1985, GEC and THOMSON started a collaboration on these subjects, supported by an ESPRIT grant from the Commission of the European Com munity. To the outside observer of the whole field, it appears clear that the world effort is very largely based in the United States and Japan. It also appears that cooperation and dissemination of results are very well organised outside Europe and act as a major influence on the development of new concepts and devices. In Japan, a main research programme of the Research and Development for Basic Technology for Future Industries is focused on "Future Electron Devices". In Japan and in the United States, many workshops are organised annually in order to bring together the major specialists in industry and academia, allowing fast dissemination of advances and contacts for setting up cooperative efforts.

The enzymatic polymerization of phenolic compounds has been generating interest in several fields such as food, cosmetics, and pharmaceuticals. These compounds are employed for their antioxidant properties; however, their use is limited by their low solubility and thermal stability. Polymerization can improve their solubility and their thermal stability though and create new properties which are dependent on the molecular mass and the structure of polymers. The reaction yield, the polydispersity, the molecular mass, the structure and the properties of synthesized polymers can be controlled by the mode of control of the reaction and by the reaction conditions. Enzymatic polymerization of phenolic compounds by oxidoreductases analyze the processes used and the key factors (temperature, solvent, origin of the enzyme, structure of the substrate, reactor design, ...) which control the polymerization of phenolic species by these oxidoreductase enzymes in order to obtain polymers with desired characteristics and properties.

The problems related to crazing in polymers are of special interest to polymer scientists since only polymers display this universal phenomenon and no analogues are available for low-molecular-mass compounds. The important problems of solvent crazing and the development of a universal description of polymer structure and properties have received much attention from many leading scientists. Nevertheless, some aspects of polymer crazing are still unclear, and scientific activities in this area are in progress. This work provides an up-to-date account of scientific advances in the area of solvent crazing. The principal features and stages of solvent crazing (craze nucleation, craze tip advance, craze thickening, and craze collapse at high strains) are described. Additionally, the authors present information concerning the activities of Russian scientists in this area, which might have escaped the attention of their colleagues because of the language barrier.
