[...]... materials Case studies are presented and, in some instances, conclusions and projections for optimal design procedures of nanoparticles and porous materials are offered The scope of this volume is inherently multidisciplinary from the viewpoint of usage of materials The common factor, however, is that their surface chemical behavior mates, and thus, unification of purpose and scope becomes a reality The... Heat of Adsorption of Pure Gas and Multicomponent Gas Mixtures on Microporous Adsorbents 501 Shivaji Sircar and Madhukar B Rao art 111 Adsorption from the Liquid Phase onto Nanoparticles and Porous Solids 20 Surface Chemistry of Activated Carbon Materials: State of the Art and Implications for Adsorption 529 Ljubisa R Radovic 21 Charge Regulation at the Surface of a Porous Solid Boris V Zhrnud and Lennart... sections, each of which addresses fundamental and practical realization of the production of nanostructured materials The first section deals with the preparation, characterization, and transport properties of this unique class of materials Structural and chemical heterogeneity are the result of preparation protocols, and various spectroscopies can be used to characterize these properties Transport of adsorbates... The purpose of this volume, therefore, is to collect state -of- the-art procedures for construction and design of nanoparticles and porous materials, where their applications might be most appropriate To that end, synthesis and characterization procedures are presented The ultimate test is their practical utilization in world" environments that exist at the gas and liquid interfaces of these materials. .. Equilibria and Kinetics: Rationalizations of the Elovich Equation 355 WladyslawRudzinski and Tornasz Panczyk 16 Single- and Multicomponent Adsorption Equilibria of Hydrocarbons on Activated Carbon: The Role of Micropore Size Distribution 391 K and D Do 17 Surface and Structural Properties of Modified Porous Silicas Michal Kruk and Mietek Jaroniec 443 18 Nanodimensional Magnetic Assembly of Confined... gas-solid and liquid-solid interfaces of porous materials have been the focus of many studies, over decades In recent years, materials have become the focus of many researchers Such materials have interesting properties, but they d o not definitively promise to change the state of science or technology What might change is our use of design strategies for converting theoretical materials into practical materials. .. sections are quite diverse, which is a reflection of the versatility of nanoparticles and porous materials in technologies that demand superior performance, yet still require latitude for optimization strategies Each of the contributions has been peer-reviewed and we feel confident that the information contained is complete and can be used by seasoned researchers and newcomers Copyright 1999 by Marcel Dekker...
