Interphases and Mesophases in Polymer Crystallization I
Polyethylene forms a two-dimensional hexagonal phase, stable at 3 GPa depending on molecular length, which in recent years has been claimed to intervene in crystallization prior to the formation of the usual orthorhombic phase even at atmospheric pressure. This claim is evaluated and shown to be without substance. There is very little evidence that the theoretical possibility of thin lamellae being more stable in the hexagonal phase than the orthorhombic at atmospheric pressure, if the former has sufficiently low fold surface free energy, does occur in practice. But the existence of single crystals of the orthorhombic phase unambiguously shows that they did not have a hexagonal precursor; that would have made them threefold twins. The overwhelming mass of evidence is that orthorhombic and hexagonal phases crystallize independently in accordance with the phase diagram and kinetic competition during growth, as has been understood since the hexagonal phase was discovered.

Interfacial Nanochemistry : Molecular Science and Engineering at Liquid-Liquid Interfaces
The presence of liquid-liquid interface means that real liquids are far from ideal liquids that must be miscible with any kinds of liquids and have no interface. Thus it can be said that the non-ideality of liquids might generate the liquid-liquid interface indeed and that biological systems might be generated from the non-ideal interface. The liquid-liquid interface has been, therefore, studied as a model of biological membrane. From pairing two-phases of gas, liquid and solid, nine different pairs can be obtained, which include three homo-pairs of gas-gas, liquid-liquid and solid-solid pairs. The gas-gas interface, however, is practically no use under the ordinary conditions. Among the interfaces produced by the pairing, the liquid-liquid interface is most slippery and difficult to be studied experimentally in comparison with the gas-liquid and solid-liquid interfaces, as the liquid-liquid interface is flexible, thin and buried between bulk liquid phases. Therefore, in order to study the liquid-liquid interface, the invention of innovative measurement methods has a primary importance.

Integrated Reaction and Separation Operations : Modelling and experimental validation
The book presents the latest developments in simulation of integrated processes as well as new methods of process synthesis and process control. It shows details of experimental approaches for model validation, determining of model parameters and measurement techniques. The combination of sophisticated modelling, optimisation methods and experimental results has not ben published up to now. The book gives deep insights into the overall evaluation of integrated processes as well as development of methods for a systematic design and optimisation of integrated reaction and separation processes. Potentials for process integration and the technical as well as economic limitations have been identified. The book covers several case studies of reactive distillation, reactive extraction, reactive gas-adsorption and chromatographic reactors which have been investigated from the modelling and experimental point of view. Based on validated models process simulation was used to optimize these processes. Following the concept of integrated process design approaches have been developed for model predictive control and process optimisation during production. Another new and very important focus of the book is systematic synthesis of integrated processes.

Innovative Superhard Materials and Sustainable Coatings for Advanced Manufacturing ; Proceedings of the NATO Advanced Research Workshop on Innovative Superhard Materials and Sustainable Coating, Kiev, Ukraine,12 - 15 May 2004.
Modern industry imposes ever increasing requirements upon tools and tool materials as to the provision for performance under the conditions of high cutting speeds and dynamic loads as well as under intensive thermal and chemical interactions with workpiece materials. The industry demands a higher productivity in combination with the accuracy of geometry and dimensions of workpieces and quality of working surfaces of the machined pieces. These requirements are best met by the tool superhard materials (diamond and diamond-like cubic boron nitride). Ceramics based on silicon carbide, aluminum and boron oxides as well as on titanium, silicon and aluminum nitrides offer promise as tool materials. Tungsten-containing cemented carbides are still considered as suitable tool materials. Hi- hardness and high strength composites based on the above materials fit all the requirements imposed by machining jobs when manufacturing elements of machinery, in particular those operating under the extreme conditions of high temperatures and loads.

Industrial enzymes : Structure, function and applications
Man's use of enzymes dates back to the earliest times of civilization. Important human activities such as the production of certain types of foods and beverages, and the tanning of hides and skins to produce leather for garments, serendipitously took advantage of enzyme activities. Important advances in our understanding of the nature of enzymes and their action were made in the late 19th and early 20th centuries, seeding the explosive expansion from the 1950s and 60s onward to the present billion dollar enzyme industry. Recent developments in the fields of genetic engineering and protein chemistry are bringing ever more powerful means of analysis to bear on the study of enzyme structure and function that will undoubtedly lead to the rational modification of enzymes to match specific requirements as well as the design of new enzymes with novel properties.
