Protein-Lipid Interactions
1st Edition
Volume 25
Anthony Watts
English
Protein-lipid interactions as a field of study is now a mature area, and this volume of NewComprehensive Biochemistry has been published with two objectives in mind. Firstly, to look to thefuture, and try to envisage how the subject may develop in the near to medium future. Secondly, to presentcontrasting or complementary views on the same system. For example, the acetylcholine receptor is discussedfrom a predominantly structural aspect by Barrantes, and from the kinetic standpoint by Rankin, et al.The volume not only gives an update on specific aspects of the field, but also shows the way in whichthe phenomenon of protein-lipid interactions is now seemingly infiltrating many areas of biomembraneresearch, from recombinant DNA studies, protein insertion and assembly and reconstitution considerationsto structural studies of membrane proteins.

Ocean Energies
Environmental, Economic and Technological Aspects of Alternative Power Sources
1st Edition
Volume 56
R.H. Charlier + 1 more
English
This timely volume provides a comprehensive review of current technology for all ocean energies. It opens with an analysis of ocean thermal energy conversion (OTEC), with and without the use of an intermediate fluid. The historical and economic background is reviewed, and the geographical areas in which this energy could be utilized are pinpointed. The production of hydrogen as a side product, and environmental consequences of OTEC plants are looked at. The competitiveness of OTEC with conventional sources of energy is analysed. Optimisation, current research and development potential are also examined.Separate chapters provide a detailed examination of other ocean energy sources. The possible harnessing of solar ponds, ocean currents, and power derived from salinity differences is considered. There is a fascinating study of marine winds, and the question of using the ocean tides as a source of energy is examined, focussing on a number of tidal power plant projects, including data gathered from China, Australia, Great Britain, Korea and the USSR.Wave energy extraction has excited recent interest and activity, with a number of experimental pilot plants being built in northern Europe. This topic is discussed at length in view of its greater chance of implementation. Finally, geothermal and biomass energy are considered, and an assessment of their future is given.Each chapter contains bibliographic references. The author has also distinguished between energy schemes which might be valuable in less-industrialized regions of the world, but uneconomical in the developed countries. A large number of illustrations support the text.Every effort has been made to ensure that the book is readable and accessible for the specialist as well as the non-expert. It will be of particular interest to energy economists, engineers, geologists and oceanographers, and to environmentalists and environmental engineers.
Bioaffinity Chromatography
2nd Edition
Volume 55
J. Turková
English
Bioaffinity chromatography is now the preferred choice for the purification, determination or removal of many biologically active substances. The book includes information on biologically active substances with their affinants, solid supports and methods of coupling, summarized in tables covering classical, high-performance liquid and large-scale bioaffinity chromatography.Optim... of the preparation and the use of highly active and stable biospecific adsorbents is discussed in several chapters. Following a chapter dealing with the choice of affinity ligands, affinity-sorbent bonding is described in detail. Other chapters give information on solid supports, the most common coupling procedures and a general discussion of sorption and elution. Several applications of bioaffinity chromatography are described, e.g. quantitative evaluation of biospecific complexes and many applications in medicine and in the biotechnology industry.

Catalysis
An Integrated Approach to Homogeneous, Heterogeneous and Industrial Catalysis
1st Edition
Volume 79
J.A. Moulijn + 2 more
English
Catalysis is a multidisciplinary activity which is reflected in this book. The editors have chosen a novel combination of basic disciplines - homogeneous catalysis by metal complexes is treated jointly with heterogeneous catalysis with metallic and non-metallic solids. The main theme of the book is the molecular approach to industrial catalysis.In the introductory section Chapter 1 presents a brief survey of the history of industrial heterogeneous and homogeneous catalysis. Subsequently, a selection of current industrial catalytic processes is described (Chapter 2). A broad spectrum of important catalytic applications is presented, including the basic chemistry, some engineering aspects, feedstock sources and product utilisation. In Chapter 3, kinetic principles are treated.The section on fundamental catalysis begins with a description of the bonding in complexes and to surfaces (Chapter 4). The elementary steps on complexes and surfaces are described. The chapter on heterogeneous catalysis (5) deals with the mechanistic aspects of three groups of important reactions: syn-gas conversion, hydrogenation, and oxidation. The main principles of metal and metal oxide catalysis are presented. Likewise, the chapter on homogeneous catalysis (6) concentrates on three reactions representing examples from three areas: carbonylation, polymerization, and asymmetric catalysis. Identification by in situ techniques has been included. Many constraints to the industrial use of a catalyst have a macroscopic origin. In applied catalysis it is shown how catalytic reaction engineering deals with such macroscopic considerations in heterogeneous as well as homogeneous catalysis (Chapter 7). The transport and kinetic phenomena in both model reactors and industrial reactors are outlined.The section on catalyst preparation (Chapters 8 and 9) is concerned with the preparation of catalyst supports, zeolites, and supported catalysts, with an emphasis on general principles and mechanistic aspects. For the supported catalysts the relation between the preparative method and the surface chemistry of the support is highlighted. The molecular approach is maintained throughout. The first chapter (10) in the section on catalyst characterization summarizes the most common spectroscopic techniques used for the characterisation of heterogeneous catalysts such as XPS, Auger, EXAFS, etc. Temperature programmed techniques, which have found widespread application in heterogeneous catalysis both in catalyst characterization and simulation of pretreatment procedures, are discussed in Chapter 11. A discussion of texture measurement, theory and application, concludes this section (12). The final chapter (13) gives an outline of current trends in catalysis. Two points of view are adopted: the first one focusses on developments in process engineering. Most often these have their origin in demands by society for better processes. The second point of view draws attention to the autonomous developments in catalysis, which is becoming one of the frontier sciences of physics and chemistry. In this book emphasis is on those reactions catalyzed by heterogeneous and homogeneous catalysts of industrial relevance. The integrative treatment of the subject matter involves many disciplines, consequently, the writing of the book has been a multi-author task. The editors have carefully planned and harmonized the contents of the chapters.
Heterogeneous Catalysis and Fine Chemicals III
1st Edition
Volume 78
J. Barbier + 6 more
English
Heterogeneous catalysis plays a major role in the organic synthesis of specialty and fine chemicals. However, as the interaction between surface sites and functional groups is complex, more investigations are necessary into the effects of catalysts on the reaction mechanisms. The Third International Symposium on Heterogeneous Catalysis and Fine Chemicals provided an opportunity for discussions on the basic and practical aspects of this subject between researchers, manufacturers and users of solid catalysts for synthesis of fine chemicals.The present volume comprises the invited plenary lectures and research papers classified under the three main headings, hydrogenation, oxidation and acid-catalysis. All papers were refereed. A large variety of reactions are described, the emphasis being on selectivity, taking into account all aspects: chemo-, regio-, and stereoselectivity (including enantioselectivity) and on the change of these selectivities as a function of the characteristics of the catalysts and operating conditions.

Thin Films in Tribology
1st Edition
G. Dalmaz + 4 more
English
The tribological properties of relatively moving surfaces are greatly influenced by thin surface films which are of considerable importance in the design of machine components. From Victorian days when working lubricant films were calculated in tens of micrometres, to today when molecular dynamics simulations and even experiments are beginning to look at nanometre, single molecule thick films, the study of surfaces which is the tribologists' challenge has moved to finer and finer scales.The 66 papers in this volume provide reviews across the tribological field with thin films as their theme, giving a comprehensive and concise description on topics ranging from coatings and surface modification to bio-tribology. The articles provide the reader with an outline of their most effective application and potential uses in new technologies. The volume will be of interest not only to research workers and design engineers in the fields of new machine developments and lubrication, but also to engineers and students specialising in tribology.
