Porous Materials from the Author: Kozo Ishizaki. Approximately four million years of human history has passed. We have been using materials to make a variety of tools. The first materials used were naturally occurring materials such as animal bones, stones, wood etc.; and some of these familiar materials are porous. Porous materials are so familiar that they are sometimes forgotten or ignored. The taste experience of ice cream is created not only by adjusting ingre dients, but also by including air as an ingredient, i.e. pores that give the smooth texture of ice cream. This book is designed to describe and explain about pores, the synthesis of materials with pores (porous materials), and applications of porous materi als. This book is intended for engineers and scientists of different disciplines and specialities, and is expected to be useful in the design and synthesis of porous materials for existing as well as potential new applications. Let us rediscover pores. K. Ishizaki, S. Komameni and M. Nanko January 1998 1 Introduction 1.1 WHAT ARE POROUS MATERIALS? Porous materials are dermed as solids containing pores. Figure 1.1 shows different porous materials. Generally speaking, porous materials have a porosity of 0.2-0.95. The porosity means the fraction of pore volume to the total volume. Porous materials have been used in various applications from daily necessities, such as purifying drinking water by activated carbon or porous ceramics, to uses in modern industries, for example removing dusts from high purity process gases for semiconductor production.

Electrochemistry Of Porous Materials from the Author: Antonio Doménech Carbó. Porous materials continue to attract considerable attention because of their wide variety of scientific and technological applications, such as catalysis, shape- and size-selective absorption and adsorption, gas storage, and electrode materials. Both research and applications of porous materials—via electroanalysis, electrosynthesis, sensing, fuel cells, capacitors, electro-optical devices, etc.—heavily rely on electrochemistry. Electrochemistry of Porous Materials focuses on generalized theoretical modeling and describes redox processes for different porous materials, assessing their electrochemical applications. Considering the large variety of materials that can be classified as porous, the text focuses on nanostructured micro- and mesoporous materials. Using this approach, the book offers a more focused and practical analysis of key porous materials that are considered relatively homogeneous from an electrochemical point of view. These include: Porous silicates and aluminosilicates Porous metal oxides and related compounds Porous polyoxometalates Metal-organic frameworks Porous carbons, nanotubes, and fullerenes Porous polymers and certain hybrid materials With its detailed presentation of advances in electrochemistry of nanostructured materials, this text specifically addresses the foundation and applications of the electrochemistry of microporous materials. It incorporates the latest breakthroughs in applied fields (development of fuel cells, supercapacitors, etc.) and fundamental research (in areas including fractal scaling, photoelectrocatalysis, magnetoelectrochemistry, etc.). Designed to make the topic accessible and understandable for researchers and graduate students working in the field of material chemistry, this volume approximates porous materials chemistry to electrochemists. Selective and streamlined, it culls a wide range of relevant and practically useful material from the extensive literature on the subject, making it an invaluable reference for readers of all levels of understanding.

Porous Materials from the Author: Duncan W. Bruce. In the past few decades, the increasingly routine use of advanced structural probes for studying the structure and dynamics of the solid state has led to some dramatic developments in the field of porous solids. These materials are fundamental in a diverse range of applications, such as shape-selective catalysts for energy-efficient organic transformations, new media for pollutant removal, and gas storage materials for energy technologies. Porosity in inorganic materials may range from the nano-scale to the macro-scale, and the drive towards particular properties remains the goal in this fast-developing area of research. Covering some of the key families of inorganic solids that are currently being studied, Porous Materials discusses: Metal Organic Frameworks Materials Mesoporous Silicates Ordered Porous Crystalline Transition Metal Oxides Recent Developments in Templated Porous Carbon Materials Synthetic Silicate Zeolites: Diverse Materials Accessible Through Geoinspiration Additional volumes in the Inorganic Materials Series: Low-Dimensional Solids | Molecular Materials | Functional Oxides | Energy Materials

Porous Materials In Environmentally Friendly Processes from the Author: I. Kiricsi. To leave our planet liveable in the next millennium mankind is forced to find environmentally friendly ways in solving the problems of everyday life. Among others, technologies of producing chemicals, absolutely necessary for maintaining a comfortable life, have to be modified, in some instances fundamentally changed now, or in the very near future. Developing new technologies requires strong and innovative fundamental research. In order to provide opportunity for crossfertilization the Federation of European Zeolite Associations (FEZA) decided to organise a conference, where researchers from academia as well as industry can meet, exchange ideas, show and discuss research efforts and results concerning the development of environmentally friendly processes and technologies. The conference, and thus the proceedings are divided into two main parts. The first part contains works concerning the synthesis, modification and characterisation of zeolitic materials as catalyst candidates in environmentally friendly technologies. Works in the second part describe various applications starting from developing highly selective reactions for the fine chemical industry, through waste-water treatment to applying zeolite for formulating bacteria for pest control.

Modeling And Mechanics Of Granular And Porous Materials from the Author: Gianfranco Capriz. Soils are complex materials: they have a particulate structure and fluids can seep through pores, mechanically interacting with the solid skeleton. Moreover, at a microscopic level, the behaviour of the solid skeleton is highly unstable. External loadings are in fact taken by grain chains which are continuously destroyed and rebuilt. Many issues of modeling, even of the physical details of the phenomena, remain open, even obscure; de Gennes listed them not long ago in a critical review. However, despite physical complexities, soil mechanics has developed on the assumption that a soil can be seen as a continuum, or better yet as a medium obtained by the superposition of two and sometimes three con and the other fluids, which occupy the same portion of tinua, one solid space. Furthermore, relatively simple and robust constitutive laws were adopted to describe the stress-strain behaviour and the interaction between the solid and the fluid continua. The contrast between the intrinsic nature of soil and the simplistic engi neering approach is self-evident. When trying to describe more and more sophisticated phenomena (static liquefaction, strain localisation, cyclic mo bility, effects of diagenesis and weathering, ..... ), the nalve description of soil must be abandoned or, at least, improved. Higher order continua, incrementally non-linear laws, micromechanical considerations must be taken into account. A new world was opened, where basic mathematical questions (such as the choice of the best tools to model phenomena and the proof of the well-posedness of the consequent problems) could be addressed.
