MFI zeolite characterized by uniform pore size, adjustable acidity, and high-temperature resistance has a broad application prospect in catalytic reactions. However, controlling the product distribution of zeolite as a catalyst is still confronting great challenges and applications. It is considered as an effective way to control the product distribution by developing and improving new zeolites to modulate their shape selective effect. In recent years, researchers have achieved remarkable successes in investigating the shape selective modulation of zeolites on catalytic reaction and molecular diffusion. The microporous channels of MFI zeolite are the main places for the entry and exit of reactants or product molecules. This review provides the research progress of the shape-selective modulation of MFI zeolite channels and its influence on a series of catalytic performances in recent years. The shape-selective modulation of microporous channels of zeolite, encapsulation of micropores to metals, catalysis of mesoporous zeolite, and the distribution of framework Al were all systematically discussed. The development of advanced catalysts still faces great challenges and potential applications. Finally, we discussed the problems to be addressed urgently in the field of zeolite catalysts in the future.

The Zeolites and Mesporous Materials at the Dawn of the 21st Century Proceedings are the expression of the oral and poster communications which where presented during the 13th International Zeolite Conference (IZC). They are subdivided into 32 thematic sessions starting from the genesis of materials to their applications through their characterisation. The paper volume contains the full texts of the 5 plenary and 6 keynote lectures and informative summaries of 150 oral and 540 poster presentations. These contributions have been selected among the 903 submissions received from a total of 57 countries! In order to gather all the communications in a handy document, the full texts of oral and poster presentations are available in CD-ROM. Besides the fields of zeolite science always represented at IZC (synthesis, characterisation, catalysis, etc¿), some subjects strengthened their position (mesoporous materials, theory and modelling), new areas emerge (advanced materials, environmental and life sciences) and older ones regain interest (natural zeolites). The understanding and development of the unique properties of porous materials relies on a unique blend of multidisciplinary knowledge: material science, with the implication of organic and colloid chemistry, to prepare micro- and mesoporous materials, surface and adsorption science sustained by theory and modelling to understand the peculiar behaviour of molecules in confined systems, special branches of catalysis, physics, chemical engineering and life science to design novel applications. The gathering of these elements is at the basis of a fruitful and evolutionary zeolite science, as it is hopefully reflected by these proceedings.

The Special Court for Sierra Leone was established through signature of a bilateral treaty between the United Nations and the Government of Sierra Leone in early 2002, making it the third modern ad hoc international criminal tribunal. The tribunal has tried various persons, including former Liberian President Charles Ghankay Taylor, for allegedly bearing "greatest responsibility" for serious violations of international humanitarian law committed during the latter half of the Sierra Leonean armed conflict. It completed its work in December 2013. A new Residual Special Court for Sierra Leone, based in Freetown and with offices in The Hague, has been created to carry out its essential “residual” functions. This volume, which consists of three books and a CD-ROM and is edited by two legal experts on the Sierra Leone court, presents, for the first time in a single place, a comprehensive collection of all the interlocutory decisions and final trial and appeals judgments issued by the court in the case Prosecutor v. Charles Ghankay Taylor. The Taylor case is the jewel in the crown of the SCSL, as it was the first ever trial and conviction of a former African head of state for crimes committed in a neighboring state. It is also one of a handful of such significant cases in international criminal law. The Taylor Law Report contains the full text of all substantive judicial decisions, including the majority, separate and concurring as well as dissenting opinions and probably the longest trial judgment ever issued by an international criminal court. It additionally provides relevant information for a better understanding of the case, such as the indictments, a list of admitted exhibits and a list of documents on the case file. This book set, which is the third in a series of edited law reports that follows volume 1 (on Prosecutor v. Brima, Kamara and Kanu – the so-called “AFRC case” published in November 2012) and volume 2 (Prosecutor v. Norman, Fofana and Kondewa – the “CDF case” published in March 2014) seeks to capture the entire jurisprudential legacy of the tribunal, fills the gap for a single and authoritative reference source of the tribunal’s jurisprudence. These law reports, the last volumes of which will be published in 2015 and 2016, are intended for national and international judges, lawyers, academics, students and other researchers as well as transitional justice practitioners in courts, tribunals and truth commissions as well as anyone seeking an accurate record of the trials conducted by the Special Court for Sierra Leone. N.B.: The hardback copy of this title contains a CD-ROM with the scanned decisions that are reproduced in the book and the trial transcripts. The e-book version does not.

A comprehensive, practical guide to wood-plastic composites and their properties This is the first book that presents an overview of the main principles underlying the composition of wood-plastic composite (WPC) materials and their performance in the real world. Focusing on the characteristics of WPC materials rather than their manufacture, this guide bridges the gap between laboratory-based research and testing and the properties WPC materials exhibit when they're used in decks, railing systems, fences, and other common applications. Complete with practical examples and case studies, this guide: Describes compositions of WPC materials, including thermoplastics, cellulose fiber, minerals, additives, and their properties Covers mechanical properties, microbial resistance, water absorption, flammability, slip resistance, thermal expansion-contraction, sensitivity to oxidation and solar radiation, and rheological properties of hot melts of WPC Covers subjects that determine esthetics, properties, performance, and durability of wood-plastic composite products Includes comparisons of different ASTM methods and procedures that apply to specific properties This is a comprehensive, hands-on reference for scientists, engineers, and researchers working with wood-plastic composites in plastics and polymers, materials science, microbiology, rheology, plastic technology, and chemical engineering, as well as an outstanding text for graduate students in these disciplines. It's also an excellent resource for suppliers and WPC manufacturers, and an accessible guide for developers, homebuilders, and landscape architects who want to know more about wood-plastic composites and their performance in the real world.
