Nanoporous Materials Iv

Nanoporous Materials IV contains the invited lectures and peer-reviewed oral and poster contributions to be presented at the 4th International Symposium on Nanoporous Materials, which will be hosted in Niagara Falls, Ontario, Canada, June 7-10, 2005. This volume covers complementary approaches to and recent advances in the field of nanostructured materials with pore sizes larger than 1nm, such as periodic mesoporous molecular sieves (e.g., MCM-41 and SBA-15) and related materials including clays, ordered mesoporous carbons, colloidal crystal templated materials, porous polymers and sol gels. The broad range of topics covered in relation to the synthesis and characterization of ordered mesoporous materials are of great importance for advanced adsorption, catalytic, separation and environmental processes as well as for the development of nanotechnology. This volume contains over 120 contributions related to the synthesis of ordered mesoporous silicas, organosilicas, nonsiliceous inorganic materials, carbons, polymers and related materials, their characterization and applications in adsorption, catalysis and environmental clean up. * Unique contributions brings readers up-to-date on new research and application developments * Figures and tables supplement comprehensive topics * Extensive author and subject index

This proceedings volume contains selected and peer-reviewed original oral and poster contributions to be presented at the 5th International Symposium on Nanoporous Materials, Vancouver, Canada, May 25OCo28, 2008. It presents recent scientific advances in the area of nanoporous materials, especially those with ordered pores of sizes between 1 and 50 nm, their synthesis, characterization and applications in adsorption, catalysis, bio-related processes, environmental cleanup and nanotechnology.

Nanoporous materials consist of a regular organic or inorganic framework supporting a porous structure. Nanoporous materials are separated into three subtypes: microporous materials, mesoporous materials and macroporous materials. In recent years, nanoporous materials have been recognized as promising candidates for the multifunctional applications such as catalysis, ion-exchange, gas storage low density magnetic storage, etc. In addition, nanoporous materials are also of scientific and technological importance because of their ability to absorb and co-operate with atoms, ions and molecules on their sizeable interior surfaces and pore space. This book proposes and reviews advances being made in the field of nanoporous materials.

In the past two decades, the field of nanoporous materials has undergone significant developments. As these materials possess high specific surface areas, well-defined pore sizes, and functional sites, they show a great diversity of applications such as molecular adsorption/storage and separation, sensing, catalysis, energy storage and conversion,

This NATO ASI involved teachings and perspectives of the state-of-the-art in experimental and theoretical understandings of transport in nanoporous solids. This workshop brought together the top scientists and engineers in each area to discuss the similarities and differences in each technique and theory. The lectures truly bridge the gaps between these related areas and approaches. The applications in future separations, catalysis, the environment and energy needs are obvious. The solids comprised the newly developing molecular sieves, biological systems and polymeric solids. Transport in single particles, in membranes and in commercial applications were reviewed and analyzed, placing each in context. Techniques such as uptake, Chromatographic, Frequency Response, NMR, Neutron Scattering and Infrared spectroscopies are discussed for mixtures as well as for single components. Theoretical approaches such as Density Functional Theory, Statistical Mechanics, Molecular Dynamics and Maxwell-Stefan Theory are employed to analyze the diffusional transport in confined environments, spanning from sub-nanometers to centimetre scales. In all cases the theories are related to the experiments. These lectures present a uniquq opportunity to learn the various theoretical and experimental approaches to analyze and understand transport in nanoporous materials.

Having successfully replaced elements used in traditional, pollution-prone, energy-consuming separation processes, nanoporous materials play an important role in chemical processing. Although their unique structural or surface physicochemical properties can, to an extent, be tailored to meet specific process-related requirements, the task of charac
