Characterization of Porous Solids and Powders: Surface Area, Pore Size and Density


Book Description

The growth of interest in newly developed porous materials has prompted the writing of this book for those who have the need to make meaningful measurements without the benefit of years of experience. One might consider this new book as the 4th edition of "Powder Surface Area and Porosity" (Lowell & Shields), but for this new edition we set out to incorporate recent developments in the understanding of fluids in many types of porous materials, not just powders. Based on this, we felt that it would be prudent to change the title to "Characterization of Porous Solids and Powders: Surface Area, Porosity and Density". This book gives a unique overview of principles associated with the characterization of solids with regard to their surface area, pore size, pore volume and density. It covers methods based on gas adsorption (both physi and chemisorption), mercury porosimetry and pycnometry. Not only are the theoretical and experimental basics of these techniques presented in detail but also, in light of the tremendous progress made in recent years in materials science and nanotechnology, the most recent developments are described. In particular, the application of classical theories and methods for pore size analysis are contrasted with the most advanced microscopic theories based on statistical mechanics (e.g. Density Functional Theory and Molecular Simulation). The characterization of heterogeneous catalysts is more prominent than in earlier editions; the sections on mercury porosimetry and particularly chemisorption have been updated and greatly expanded.




Particle Size Analysis in Industrial Hygiene


Book Description

Particle Size Analysis in Industrial Hygiene discusses technical information on particle properties, kinetic behavior, sampling instruments, and interpretation. This book is composed of seven chapters and is prepared by the American Industrial Hygiene Association for the Division of Technical Information, United States Atomic Energy Commission. This monograph is a part of the continuing effort of both organizations to extend the field of technical knowledge and safeguard the health and well-being of persons exposed to toxic or deleterious material. After briefly discussing the fundamental physics and chemistry of aerosol systems, the book goes on describing the analytical methods and instruments for particle size analysis. Such methods include direct and indirect sampling methods as well as automatic counting and sizing instruments. Specific methods considered include sieve analysis, optical and electron microscopy, and scanning electron microscopy. A chapter on particle size interpretation and representation with the use of applied mathematical statistics concepts is also provided. This book also covers a general discussion on typical applications of particle size analysis to industrial hygiene, radiation protection, air pollution control, industrial toxicology, and related areas. This book is an invaluable source for industrial hygienists and to those working in the many disciplines dealing with particle behavior.
