    The overall theme of the 3rd World Congress is "Atom Efficient Catalytic Oxidations for Global Technologies". This theme was chosen to stimulate the participants to report their findings with an emphasis on conserving valuable material in their catalytic transformations, as well as conserving energy, in an environmentally responsible manner. Progress towards this stated goal is substantial as evidenced by the tremendous response of the community in their participation of quality publications complied in these Proceedings of the Congress.The subjects presented span a wide range of oxidation reactions and catalysts. These include the currently important area of lower alkane oxidation to the corresponding olefins, unsaturated aldehydes, acids and nitriles.The four featured lectures and seven plenary lectures constitute the general background and overview of the subject matter at hand. The 104 contributed papers and 13 poster manuscripts, summarized in this compendium, probe new avenues to achieve catalytically efficient oxidation reactions for the future needs of mankind in a global environment.

  • XIVth International Symposium on Medicinal Chemistry

    Vaso-occlusive disorders including unstable angina, myocardial infarction, transient ischemic attacks, stroke and peripheral artery disease remain the major sources of morbidity and mortality in western civilization. Platelet activation and resulting platelet aggregation play a major role in the pathogenesis of these thromboembolic diseases. Recognition of the contribution of platelets to the pathophysiology of cardiovascular disease has provided impetus for the continued search for new antiplatelet agents. Hence, over the past two decades many strategies have been evaluated in the search for efficacious mechanisms to reduce platelet function. The medical need for more efficacious antithrombotic drugs and the growing understanding of the role of platelets in vascular injury have catalyzed the extensive evaluation of novel approaches to control platelet function. Along these lines, the volume therefore provides an in-depth assessment of ongoing clinical trials, new and clinically established agents, and other developments in this rapidly developing field.

  • Dynamics of Surfaces and Reaction Kinetics in Heterogeneous Catalysis

    • 1st Edition
    • Volume 109
    • G.F. Froment + 1 more
    • English
    Many processes of the chemical industry are based upon heterogeneous catalysis. Two important items of these processes are the development of the catalyst itself and the design and optimization of the reactor. Both aspects would benefit from rigorous and accurate kinetic modeling, based upon information on the working catalyst gained from classical steady state experimentation, but also from studies using surface science techniques, from quantum chemical calculations providing more insight into possible reaction pathways and from transient experimentation dealing with reactions and reactors. This information is seldom combined into a kinetic model and into a quantitative description of the process. Generally the catalytic aspects are dealt with by chemists and by physicists, while the chemical engineers are called upon for mechanical aspects of the reactor design and its control. The symposium "Dynamics of Surfaces and Reaction Kinetics in Heterogeneous Catalysis" aims at illustrating a more global and concerted approach through a number of prestigious keynote lectures and severely screened oral and poster presentations.

  • Spillover and Migration of Surface Species on Catalysts

    This fourth spillover conference in Dalian exhibits advances and new results in spillover studies since 1993.In the proceedings, 5 invited lectures, 23 oral and 28 poster presentations are collected. In the 5 invited lectures, the active research areas are reviewed by well recognized scientists in the relevant fields. The first lecture highlights the fact that spillover plays a significant role in controlling the dynamic state of catalysts when it occurs in the catalytic process. The second lecture studies the surface mobility of oxygen and hydrogen using isotopic exchange method, and the impact of surface mobility on many catalytic processes is discussed. In the third paper the acidic functions of spilt-over hydrogen in a number of acid catalyzed reactions are well clarified. Subsequently, the fourth lecture explores electrochemically controlled spillover phenomenon over mm distances directly observed on metal catalysts. Finally, the last lecture reports the spontaneous dispersion of compounds onto supports and its importance in catalysis, and concludes that surface migration is a quite common process.The conference papers present a number of aspects of spillover studies, such as new spillover phenomena, new methods for spillover characterization, spillover effects in catalysis, etc. Studies on migration and mobility of surface species are also included in the conference topics, as it is believed that the migration of species is a more general phenomenon, and spillover can be considered as a special case of migration. The spillover of hydrogen and oxygen is the major issue at the conference, while the spillover of larger molecules are reported as well in some papers. Simulation and modeling of spillover and surface mobility are also a very interesting subject in the meeting.

  • Functionally Graded Materials 1996

    Since a formulated concept of functionally graded materials (FGMs) was proposed in 1984 as a means of preparing thermal barrier materials, a coordinated research has been developed since 1986. The 125 papers presented here present state of the art research results and developments on FGM from the past decade.A wide spectra of topics are covered including design and modeling, fracture analysis, powder metallurgical processes, deposition and spray processes, reaction forming processes, novel processes, material evaluation for structural applications, organic and intelligent materials. Three reviews associated with national research programs on FGMs promoted in Japan and Germany, and the historical perspective of FGM research in Europe are presented as well.The resulting work is recommended to researchers, engineers and graduate school students in the fields of materials science and engineering, mechanical and medical engineering.

  • In VIVO Footprinting

    • 1st Edition

    • English
    The revolution in biological research initiated by the demonstration that particular DNA molecules could be isolated, recombined in novel ways, and conveniently replicated to high copy number in vivo for further study, that is, the recombinant DNA era, has spawned many additional advances, both methodological and intellectual, that have enhanced our understanding of cellular processes to an astonishing degree. As part of the subsequent outpouring of information, research exploring the mechanisms of gene regulation, both in prokaryotes and eukaryotes (but particularly the latter), has been particularly well represented. Although no one technical approach can be said to have brought the filed to its current level of sophistication, the ability to map the interactions of trans-acting factors with their DNA recognition sequences to a high level of precision has certainly been one of the more important advances. This "footprinting" approach has become almost ubiquitous in gene regulatory studies; however, it is in its "in vivo" application that ambiguities, confusions, and inconsistencies that may arise from a purely "in vitro"-based approach can often be resolved and placed in their proper perspective. Put more simply, that an interaction can be demonstrated to occur between purified factors and a particular piece of DNA in a test tube does not, of course, say anything regarding whether such interactions are occurring in vivo. The ability to probe for such interactions as they occur inside cells, with due attention paid to the relevant developmental stage, or to the tissue specificity of the interaction being probed, has made in vivo footprinting approach an invaluable adjunct to the "gene jockey's" arsenal of weapons.

  • SDL '97: Time for Testing

    SDL, MSC and Trends
    • 1st Edition
    • Ana Cavalli + 1 more
    • English
    As Cavalli and Sarma astutely remarked in the introduction to this volume, it is quite remarkable that SDL '97 may have the first participant younger than SDL itself. SDL '97 provides the opportunity to reflect the course SDL has taken and why it has been successful over two decades where other languages addressing the same market have failed.SDL now also has a permanent companion in MSC (Message Sequence Charts). MSC today is a language in its own right and has its areas of application both in conjunction with SDL and independently or in combination with other techniques. MSC has strong structuring concepts to specify message sequences for large systems and can be used to develop scenarios, which is extremely useful for test and design environments. The SDL Forum today really is the SDL and MSC Forum.
