Book Description
Since the first works introducing the aluminum intercalated clay family in the early 1970s, interest in the synthesis of pillared interlayered clays has increased tremendously, especially research into the properties and applications of new synthesis methods. The need for solids that could be used as cracking catalysts with larger pores than zeolitic materials has spurred the synthesis of new porous materials from clays. Pillared Clays and Related Catalysts reviews the properties and applications of pillared clays and other layered materials used as catalysts, focusing on: the acidity of pillared clays and the effect it has on catalytic performance the use of pillared clays as supports for catalytically active phases, and the use of the resulting solids in environmentally friendly reactions the applications of the selective reduction of NOx the comparison between the reactions of pillared clays and anionic clays.

Book Description
Proceedings of the 10th International Clays Conference, Adelaide, Australia, July 18 to 23, 1993. Clays have provided us with the most active ingredients in soils, with building materials, with pottery and ceramics for both utility and decoration, and with coatings and fillers for paper, among other uses. The unique properties of these apparently everyday materials are being studied and used in an increasing range of industrial and environmental applications. Clays: Controlling the Environment provides a valuable compendium of the latest results from the complete range of clay-related scientific research. It includes coverage of the economic and environmental issues as well as directions for further research and development in many vital and expanding industries. All papers in these proceedings were subject to peer review. The topics discussed are: Clays in industry and the environment Surface and interlayer reactions Clay mineral structures and chemistry Methods of investigation Clays in geology Soil mineralogy The emphasis of this book reflects the vital role that clays play in controlling natural, polluted and technological environments.

Book Description
The book provides insight into the working of clays and clay minerals in speeding up a variety of organic reactions. Clay minerals are known to have a large propensity for taking up organic molecules and can catalyse numerous organic reactions due to fine particle size, extensive surface area, layer structure, and peculiar charge characteristics. They can be used as heterogeneous catalysts and catalyst carriers of organic reactions because they are non-corrosive, easy to separate from the reaction mixture, and reusable. Clays and clay minerals have an advantage over other solid acids as they are abundant, inexpensive, and non-polluting.

Book Description
On January 1988, the ascertained and economically accessible reserves of Natural Gas (NG) amounted to over 144,000 billion cubic meters worldwide, corresponding to 124 billion tons of oil equivalents (comparable with the liquid oil reserves, which are estimated to be 138 billion TOE). It is hypothesized that the volume of NG reserve will continue to grow at the same rate of the last decade. Forecasts on production indicate a potential increase from about 2,000 billion cubic meters in 1990 to not more than 3,300 billion cubic meters in 2010, even in a high economic development scenario. NG consumption represents only one half of oil: 1.9 billion TOE/y as compared to 3.5 of oil. Consequently, in the future gas will exceed oil as a carbon atom source. In the future the potential for getting energetic vectors or petrochemicals from NG will continue to grow.The topics covered in Natural Gas Conversion V reflect the large global R&D effort to look for new and economic ways of NG exploitation. These range from the direct conversion of methane and light paraffins to the indirect conversion through synthesis gas to fuels and chemicals. Particularly underlined and visible are the technologies already commercially viable.These proceedings prove that mature and technologically feasible processes for natural gas conversion are already available and that new and improved catalytic approaches are currently developing, the validity and feasibility of which will soon be documented. This is an exciting area of modern catalysis, which will certainly open novel and rewarding perspectives for the chemical, energy and petrochemical industries.

Book Description
The first edition of the Handbook of Clay Science published in 2006 assembled the scattered literature on the varied and diverse aspects that make up the discipline of clay science. The topics covered range from the fundamental structures (including textures) and properties of clays and clay minerals, through their environmental, health and industrial applications, to their analysis and characterization by modern instrumental techniques. Also included are the clay-microbe interaction, layered double hydroxides, zeolites, cement hydrates, and genesis of clay minerals as well as the history and teaching of clay science. The 2e adds new information from the intervening 6 years and adds some important subjects to make this the most comprehensive and wide-ranging coverage of clay science in one source in the English language. - Provides up-to-date, comprehensive information in a single source - Covers applications of clays, as well as the instrumental analytical techniques - Provides a truly multidisciplinary approach to clay science

Book Description
The basic idea of the NATO International Exchange Program for funding an Advanced Research Workshop on "Chemical Reactions in Organic and Inorganic Constrained Systems" was to contribute to a better under standing of the influence of configurational constraints on reaction mechanisms, as imposed on reagents by organic or inorganic templates. The original character of the Workshop was to bring together organic and inorganic chemists with this common interest in order to promote the exchange of ideas and, eventually, interdisciplinary research. All the participants to the Workshop agreed that the discussions were stimulating and fruitful. The judgement of the reader of the Proceedings may perhaps be more restrictive because the director (Professor J. J. FRIPIAT) and co-director (Professor P. SINAY), faced with the impossible task of covering such an enormous domain, were obliged to select, somewhat arbitrarily, a limited number of topics which seemed to them to be the most important. Their choice may be discussed and there surely are important gaps, with fields which were not considered. However, both organisers believe that, within the limited span of time and number of contributors, most of the exciting areas were addressed. Dr. WARNHEIM was kind enough to write a commentary on the Workshop; his summary, written with the hindsight of a few weeks, supports, we believe, this opinion. Dr. SETTON has accepted the burden of collecting and shaping (not selectively) the manuscripts. This book would not be what it is without his efficient contribution as scientific secretary of the Workshop.
