Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the Proceedings of the Third International EXAFS Conference, hosted by Stanford University and the Stanford Synchrotron Radiation Laboratory on July 16-20, 1984. The meeting, co-chaired by Professors Arthur Bienenstock and Keith Hodgson, was attended by over 200 scientists representing a wide range of scientific disciplines. The format of the meeting consisted of 51 invited presenta tions and four days of poster sessions. This Proceedings is a compilation of 139 contributions from both invited speakers and authors of contributed posters. The last ten years has seen the rapid maturation of x-ray absorption spectrosco pyas a scientific discipline. The vitality of the field is reflected in the diver sity of applications found in the Proceedings. Recent work continues to probe the limits of x-ray spectroscopy, with proven techniques being extended to, for examp le, very low or high energy studies, to very dilute systems, and to studies of surface structure. In fact, the title of the conference does not at all reflect the breadth of the science discussed at this meeting. The number of fields in which x ray absorption spectroscopy is finding applications has increased dramatically even in the two years since the previous International Conference held in Frascati*. The prospects for continued growth and innovation will be even further enhanced if a new generation 6 GeV storage ring is constructed in the next five years.

Available in PDF, EPUB and Kindle. Book excerpt: Catalytic steam reforming has grown during the last two or three decades into one of the world's great catalytic processes. It is of major economic significance since the products from it form the feed for a number of other major processes. Nevertheless, catalytic steam reforming is a relatively difficult technology. It operates at high temperatures where problems of the maintenance of materials integrity and of catalyst stability and activity are severe, the establishment of high thermal efficiency of the plant is economically vital, and reactor operation is strongly influenced by mass and heat transport effects. The process is the subject of a thorough review by Dr. J. R. Rostrup-Nielsen who discusses both the basic cataly tic chemistry and the way in which this is interrelated with reactor and plant design. The use of catalytic converters for the purification of automotive exhaust gases is a relatively new technology which was brought into existence by social pressures for the preservation of acceptable environmental conditions. The majority of catalytic practitioners have been able to watch the growth of this technology from its inception to its current state of sophistication. Automotive catalytic converter technology is now in a mature state, and the chapter in this volume by Dr. K. C. Taylor provides a review which covers both the process chemistry and the most important converter design factors.

Download or read book Contribution of Clusters Physics to Materials Science and Technology written by Joel Davenas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade there has been an increasing interest in clusters and small particles because of the peculiar proper ties induced by their large area to volume ratio. For that reason small particles are often considered as an intermediate state of matter at the border between atomic (or molecular) chemistry, and physics of the condensed matter. The importance of the surface effect can explain the anomalous properties, for example the exis tence of the five fold symmetry observed in different circumstan ces '(beams of rare gas clusters, gold particles deposited on a substrate). However the question of the critical size at which the transition to bulk properties occurs cannot be simply answered, since the reply depends on the peculiar property which is studied. The importance of the size effect was emphasized in the last International Meetings. However the situation remains confused in most cases since the exact role of the cluster environment cannot be clearly elucidated and is a main difficulty, except in cluster beam experiments. In fact ideally free clusters constitute a labo ratory exception. In most applications small particles must be supported on a surface or embedded in a matrix, in order to be stabilized, which obviously shows the role of the environment.

Available in PDF, EPUB and Kindle. Book excerpt: Heterogeneous catalysis has undergone a revolutionary change in the past two decades due to the development of sophisticated characterization methods that provide fundamental information about the catalyst bulk structures, surfaces, and their properties. For the first time, these characterization methods have allowed researchers to "see" the surfaces of catalytic materials, their bulk structures (crystalline as well as amorphous phases), the influence of the process conditions on the catalytic material, as well as the effect of different synthesis methods. This new information has tremendously advanced our understanding of catalytic materials and their properties. These characterization methods have become our "eyes" and are indispensible in the development of new catalytic materials. It is hard to conceive of a modern heterogeneous catalysis activity, be it research or manufacturing, without the aid of these new characterization techniques.

Download or read book Mesoporous Molecular Sieves 1998 written by L. Bonneviot and published by Elsevier. This book was released on 1998-07-08 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original properties of mesoporous molecular sieves are so unique that the design of most existing catalysts could be reconsidered. It might indeed be of interest to introduce MMS either as a support or as the active phase, merely on the basis of their high surface areas, narrow pore size distribution and flexibility in composition. The recent literature provides examples of MMS based catalysts of many types such as acid-base solids, supported metals and supported oxides, mixed oxides, anchored complexes and clusters, grafted organic functional groups and others. Examples of all these developments are documented in the present proceedings including some spectacular new proposals. The new metallic (Pt) mesophases are specially worth mentioning because they represent a new approach to producing non-supported highly dispersed metals.In these proceedings the reader will find feature articles and regular papers from many worldwide groups, covering all aspects of synthesis, physical characterization and catalytic reactivity of MMS and their chemically modified forms. It is actually remarkable that this recent development brought together an even broader spectrum of scientists from traditionally unrelated fields such as those of liquid crystals, surfactants, sol-gels, amorphous oxides and mixed oxides, solid state, adsorbents and heterogeneous catalysts. Obviously, this is a fast-growing research area which triggers the imagination and creativity at the cross-road between material design, molecular surface tailoring and catalytic applications.
