Particle characterization is an important component in product research and development, manufacture, and quality control of particulate materials and an important tool in the frontier of sciences, such as in biotechnology and nanotechnology. This book systematically describes one major branch of modern particle characterization technology - the light scattering methods. This is the first monograph in particle science and technology covering the principles, instrumentation, data interpretation, applications, and latest experimental development in laser diffraction, optical particle counting, photon correlation spectroscopy, and electrophoretic light scattering. In addition, a summary of all major particle sizing and other characterization methods, basic statistics and sample preparation techniques used in particle characterization, as well as almost 500 latest references are provided. The book is a must for industrial users of light scattering techniques characterizing a variety of particulate systems and for undergraduate or graduate students who want to learn how to use light scattering to study particular materials, in chemical engineering, material sciences, physical chemistry and other related fields.

Particle Size Analysis reviews the development of particle characterization over the past 25 years and also speculates on its future. Interest in the subject has increased enormously over the years and this book highlights the changes and advances made within the field. This book is comprehensive in its coverage of particle size analysis and includes contributions on such characterization techniques as microscopy using fractal analysis, light diffraction, light scattering with the phase doppler technique, light observation, and photon correlation spectroscopy. A number of chapters address the interest in on-line in-stream particle size analysis and illustrate the progress being made in achieving this long sought after ideal of in-situ in-process particle characterization. Applications to other technological fields are detailed by chapters covering biological systems and the pharmaceutical industry. The subject of surface area determination is considered with particular emphasis on the measurements on porosity of powders, the characterization and comparability of reference materials, and the need for standards. Particle Size Analysis should provide stimulating reading for technologists, scientists, and engineers involved in particle characterization and powder technology worldwide.

This book develops the theory of the null-field method (also called T-matrix method), covering almost all aspects and current applications. This book also incorporates FORTRAN programs and simulation results. Worked examples of the application of the FORTRAN programs show readers how to adapt or modify the programs for their specific application.

The primary aim of this monograph is to provide a systematic state-of-the-art summary of the light scattering of bioparticles, including a brief consideration of analytical and numerical methods for computing electromagnetic scattering by single particles, a detailed discussion of the instrumental approach used in measurement of light scattering, an analysis of the methods used in solution of the inverse light scattering problem, and an introduction of the results dealing with practical analysis of biosamples. Considering the widespread need for this information in optics, remote sensing, engineering, medicine, and biology, the book is useful to many graduate students, scientists, and engineers working on various aspects of electromagnetic scattering and its applications.

This Ph.D. work deals with the scattering of light by a cloud of bubbles (i.e. particles with relative refractive index below unit) near the critical-scattering-angle. Under a single scattering assumption, a critical scattering pattern (CSP) can be accurately modeled with the Lorenz-Mie theory and a Fredholm integral of the first kind. A CSP is basically composed of several bows that are very similar to those observed in the forward diffraction zone and the rainbow region. By measuring the angular spreading, the visibility and the global position of these bows it is possible to deduce the bubbles mean size, poly-dispersion and mean refractive index (i.e. composition). We have developed several inverse methods and experiments to recover these properties, demonstrating the validity of what can be called the "Critical-Angle Refractometry and Sizing" (CARS) technique. Various effects like the laser Gaussian intensity profile or the laser beam spectrum width have also been studied. This new optical particle characterization technique is thought to be a useful tool to study real bubbly flows as well as for laboratory experiments requiring bubbles material recognition.

Laser Light Scattering: Basic Principles and Practice, Second Edition deals with the technical aspects of laser light scattering, including the basic principles and practice. Topics covered include light scattering theory, optical mixing spectrometry, photon correlation spectroscopy, and interferometry. Experimental methods and methods of data analysis are also described. This book is comprised of eight chapters and begins with a discussion on the interrelationship between laser light scattering and other types of scattering techniques that use X-rays and neutrons, with particular reference to momentum and energy transfers as well as time-averaged and time-dependent scattered intensity. The spectrum of scattered light and a single-particle approach to time-averaged scattered intensity are considered. The following chapters focus on photoelectric detection of the scattered electric field; optical mixing spectrometers; basic equations for photon correlation spectroscopy; and the principles of Fabry-Perot interferometry. The pertinent features of the experimental aspects of laser light scattering are also outlined, together with the Laplace inversion problem. The final chapter examines polymer molecular-weight distributions in relation to particle sizing. This monograph will be of interest to physicists.

Light scattering is a very powerful method for characterizing the structure of polymers and nanoparticles in solution. As part of the Springer Laboratory series, this book provides a simple-to-read and illustrative textbook probing the seemingly very complicated topic of light scattering from polymers and nanoparticles in dilute solution, and goes further to cover some of the latest technical developments in experimental light scattering.

Powder technology is a rapidly expanding technology and nowhere more than in particle characterization. There has been an explosion of new particle measuring techniques in the past ten year particularly in the field of on-line measurement. One of the main aims of this book is to bring the reader up-to-date with current practices. One important area of interest is the improvements in on-line light scattering instruments and the introduction of ultrasonic on-line devices. Another is the introduction of on-line microscopy, which permits shape analysis in conjunction with particle sizing.Schools of powder technology are common in Europe and Japan but the importance of this subject has only recently been recognised in America with the emergence of the Particle Research Centre (PERC) at the University of Florida in Gainsville. - Details all the latest developments in powder technology - Written by established authority on powder technology- A comprehensive text covering all aspects of powder technology and handling of particulate solids including characterization, handling and applications
