This volume includes papers presented at the second International Workshop on Oxide-based Systems at the Crossroads of Chemistry, held at Villa Olmo in Como, Italy, 8-11 October. The selected papers present the highlights of recent research in the field of oxide structure. A wide range of oxidic materials, including real oxides, zeolites and layer-structured systems, is considered and described in terms of preparation methods, structural characterization and the relation between active sites, structure and catalytic properties. The application of the most powerful simulation and physical-chemical techniques show their usefulness in discovering and explaining structural and dynamic properties of complex materials. Moreover the development of sophisticated spectroscopical and analytical techniques are shown to significantly improve the growth of surface oxide science, generating new tools for the knowledge of catalyst structure and reaction mechanisms. An interesting feature is the inclusion of papers which show the mutual roles of experiment and theoretical models.

Clay plays an important role in everyday life. This versatile mineral is used in housing, improving the environment as a waste treatment material and also in biological applications and medical health care. Clay Surfaces contains 17 chapters which deal with various aspects of natural and man made (synthetic) clay. Well written by experts in both experimental and theoretical areas, this book takes the reader into the fascinating world of the chemistry and physics of clay mineral surfaces and interfaces as well as the complex phenomena on the surfaces involved in clay related systems. This book will provide a better understanding of the intervention mechanisms of interactions of soils in contact with wastes, actions to be taken in the case of chemical spillage, methods to improve the production of food without affecting the ecological balance, increased fixation of carbon in the soil to increase grain production and reduction of carbon dioxide release into the atmosphere. Applications covered describe the role of clays in environmental remediation and the pharmaceutical and cosmetic industries. This book looks at theory and applications of both natural and modified clays from academic and industrial viewpoints. With broad appeal, this book is suitable for specialists directly involved in clay science and those undergraduate and graduate student studying related areas.

Since 1987, the Petroleum Division of the American Chemical Society (ACS) has sponsored at 3 year intervals an international symposium on fluid cracking catalysts (FCC) technology. This volume collects the recent progress of this technology as reported in the papers presented during the 232th National Meeting of the ACS in San Francisco, September 10-14, 2006. Sixty-six years after the introduction of the fluid cracking catalyst process, it remains the main process of gasoline generation for the estimated 237 millions cars on US roads. Catalysts testing and evaluation still remains a subject of interest, debate and controversy. Lambda sweep testing, testing of SOx, NOx and combustion promoters have been discussed in details together with catalyst evaluation for atmospheric residues and metal contaminated oils cracking. Of particular interest has been the introduction of novel concept in process design aimed at improving cracked product selectivity such as two-stage risers for better gasoline and olefins production and downer technology for high severity processes . The importance of solid state nuclear magnetic resonance (NMR) in the study of crude oils, catalysts and reaction products are illustrated by several examples. Two contributions describe the use of predictive methods to understand FCC aging and deactivation and personal overviews of the development of SOx and combustion promoters technology are presented. * Presents findings from the tri-annual international symposium on fluid cracking catalysts (FCC) technology, sponsored by the Petroleum Division of the American Chemical Society (ACS) * Two contributions describe the use of predictive methods to understand FCC aging and deactivation * Personal overviews by the authors of the development of SOx and combustion promoters technology

During the past 30 years, the field of alkene polymerization over transition metal catalysts underwent several major changes: 1. The list of commercial heterogeneous Ziegler-Natta catalysts for the synthesis of polyethylene and stereoregular polyolefins was completely renewed affording an unprecedented degree of control over the polymer structure. 2. Research devoted to metallocene and other soluble transition-metal catalysis has vastly expanded and has shifted toward complexes of transition metals with multidentate ligands. 3. Recent developments in gel permeation chromatography, temperature-rising fractionation, and crystallization fractionation provided the first reliable information about differences between various active centers in transition-metal catalysts. 4. A rapid development of high-resolution 13C NMR spectroscopy resulted in greatly expanded understanding of the chemical and steric features of polyolefins and alkene copolymers. These developments require a new review of all aspects of alkene polymerization reactions with transition-metal catalysts. The first chapter in the book is an introductory text for researchers who are entering the field. It describes the basic principles of polymerization reactions with transition-metal catalysts, the types of catalysts, and commercially manufactured polyolefins. The next chapter addresses the principal issue of alkene polymerization catalysis: the existence of catalyst systems with single and multiple types of active centers. The subsequent chapters are devoted to chemistry and stereochemistry of elemental reaction steps, structures of catalyst precursors and reactions leading to the formation of active centers, kinetics of polymerization reactions, and their mechanisms. The book describes the latest commercial polymerization catalysts for the synthesis of polyethylenes and polypropylene The book provides a detailed description of the multi-center nature of commercial Ziegler-Natta catalysts. The book devotes specialized chapters to the most important aspects of transition metal polymerization catalysts: the reactions leading to the formation of active centers, the chemistry and stereochemistry of elemental polymerization steps, reaction kinetics, and the polymerization mechanism. The book contains an introductory chapter for researchers who are entering the field of polymerization catalysis. It describes the basic principles of polymerization reactions with transition-metal catalysts and the types of commercially manufactured polyolefins and copolymers The book contains over 2000 references, the most recent up to end of 2006.
