Solid acid catalysts are already being used in various processes in petroleum refining and are presently being studied intensively in both academic and applied fields for usage in a variety of reactions. Solid base catalysts are also gaining increasing recognition as potential catalysts. Both acidic and basic catalysts are promising not only with respect to acid and base-catalyzed reactions but also in materials sciences, such as the production of adsorbents, sensors, ceramics, etc.The present volume presents the text of 21 invited oral presentations and 58 poster presentations. The material covers a wide range of aspects on acid-base catalysis, from quantum chemistry to industrialized processes.

This volume summarises and reviews the enormous progress made over the past two decades in solid acids and bases, with emphasis on fundamental aspects and chemical principles. In recent years many new kinds of solid acids and bases have been found and synthesized. The surface properties (in particular, acidic and basic properties) and the structures of the new solids have been clarified by newly developed measurement methods using modern instruments and techniques. The characterized solid acids and bases have been applied as catalysts for diversified reactions, many good correlations being obtained between the acid-base properties and the catalytic activities or selectivities. Recently, acid-base bifunctional catalysis on solid surfaces is becoming a more and more important and intriguing field of study.It has been recognized that the acidic and basic properties of catalysts and catalyst supports play an important role in oxidation, reduction, hydrogenation, hydrocracking, etc. The effect of the preparation method and the pretreatment conditions of solid acids and bases on the acidic and basic properties, the nature of acidic and basic sites and the mechanism regarding the generation of acidity and basicity have been elucidated experimentally and theoretically. On the basis of the accumulated knowledge of solid acids and bases, it is now possible to design and develop highly active and selective solid acid and base catalysts for particular reactions. The chemistry of solid acids and bases is now being related to and utilized in numerous areas including adsorbents, sensors, cosmetics, fuel cells, sensitized pressed papers, and others. The information presented in this book will therefore be of interest to a wide-ranging readership.

Endourology has developed significantly in recent years as a result of rapid change in surgical techniques and instruments. This eighth volume in the series Recent Advances in Endourology brings together the latest clinical findings regarding various endourological treatment modalities and innovative materials. In the past 30 years, transurethral resection of prostate, bladder, and ureteral tumors has been dramatically refined. Transurethral microwave thermotherapy has emerged as a nonsurgical option for the treatment of benign prostatic obstruction. Percutaneous surgery has changed significantly with the miniaturization of the endoscope, while the needle ablation technique, which decreases pain and shortens hospital stays, has become the treatment of choice for small renal cell tumors. In this book, world-recognized experts outline their techniques clearly and concisely to provide an updated review of state-of-the-art endourological techniques.
