Book Synopsis Laser Light Scattering by : Benjamin Chu
Download or read book Laser Light Scattering written by Benjamin Chu and published by Academic Press. This book was released on 2012-12-02 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Laser Light Scattering by : Charles S. Johnson
Download or read book Laser Light Scattering written by Charles S. Johnson and published by Dover Publications. This book was released on 1995-01-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light scattering has provided an important method for characterizing macro-molecules for at least three decades. Now, through the use of intense, coherent laser light and efficient spectrum analyzers and autocorrelators, experiments in the frequency and time domains can be used to study molecular motion, e.g. diffusion and flow and other dynamic processes, as well as the equilibrium properties of solutions. As a result, laser light scattering has become a powerful form of spectroscopy with applications in physics, biochemistry, and other fields. This volume, which employs a relatively simple approach in order to reach the widest audience, focuses on two main topics: classical light scattering (scattering intensity, concentration dependence, size dependence, and polydispersity) and dynamic light scattering (time and frequency dependence, translational diffusion, directed flow, rotational motion, and more). A series of useful appendixes and a list of references complete this concise, accessible work, a valuable resource for physicists, chemists, and anyone interested in the increasingly important field of laser light scattering.
Book Synopsis The Application of Laser Light Scattering to the Study of Biological Motion by : J. C. Earnshaw
Download or read book The Application of Laser Light Scattering to the Study of Biological Motion written by J. C. Earnshaw and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several previous Advanced Study Institutes have concentrated on the techniques of light scattering, while the biological appli cations were not fully explored. Many of the techniques are now standardised and are being applied to a wide range of biologically significant problems both in vivo and in vitro. While laser light scattering methods are superior to conventional methods, there was a general reluctance among biologists to adopt them because of the complexity of the physical techniques and the accompanying mathe matical analysis. Consequently valuable opportunities for advancing the understanding of the biological problems were being missed. Advances in the design and commercial availability of standard light scattering instruments, and the availability of standard computer programs, made the more widespread use of these techniques a practical reality for the biologist. While biologists are unable to cope with the complexities of the physical techniques, physicists are generally unaware of the nature and scale of the biological problems. The meeting at Maratea was an attempt to bring these two groups together and provide an impetus for the application of laser light scattering techniques to biology. This volume differs from the three previous proceedings on laser light scattering in the NATO ASI series (B3, B23, B73), in that it has been published in the Life Sciences series rather than the Physics series, reflecting the shift in emphasis from the development of a new technique to its application in biology.
Book Synopsis Dynamic Light Scattering by : Bruce J. Berne
Download or read book Dynamic Light Scattering written by Bruce J. Berne and published by Courier Corporation. This book was released on 2013-07-24 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lasers play an increasingly important role in a variety of detection techniques, making inelastic light scattering a tool of growing value in the investigation of dynamic and structural problems in chemistry, biology, and physics. Until the initial publication of this work, however, no monograph treated the principles behind current developments in the field.This volume presents a comprehensive introduction to the principles underlying laser light scattering, focusing on the time dependence of fluctuations in fluid systems; it also serves as an introduction to the theory of time correlation functions, with chapters on projection operator techniques in statistical mechanics. The first half comprises most of the material necessary for an elementary understanding of the applications to the study of macromolecules, or comparable sized particles in fluids, and to the motility of microorganisms. The study of collective (or many particle) effects constitutes the second half, including more sophisticated treatments of macromolecules in solution and most of the applications of light scattering to the study of fluids containing small molecules.With its wide-ranging discussions of the many applications of light scattering, this text will be of interest to research chemists, physicists, biologists, medical and fluid mechanics researchers, engineers, and graduate students in these areas.

Book Synopsis Particle Size Measurements by : Henk G. Merkus
Download or read book Particle Size Measurements written by Henk G. Merkus and published by Springer Science & Business Media. This book was released on 2009-01-07 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the practical aspects of particle size measurement: a major difference with existing books, which have a more theoretical approach. Of course, the emphasis still lies on the measurement techniques. For optimum application, their theoretical background is accompanied by quantitative quality aspects, limitations and problem identification. In addition the book covers the phenomena of sampling and dispersion of powders, either of which may be dominant in the overall analysis error. Moreover, there are chapters on the general aspects of quality for particle size analysis, quality management, reference materials and written standards, in- and on-line measurement, definitions and multilingual terminology, and on the statistics required for adequate interpretation of results. Importantly, a relation is made to product performance, both during processing as well as in final application. In view of its set-up, this book is well suited to support particle size measurement courses.

Book Synopsis Molecular Scattering of Light by : I. L. Fabelinskii
Download or read book Molecular Scattering of Light written by I. L. Fabelinskii and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of the laser and the subsequent expansion of research in the field of molecular scattering of light tend to ob scure the vast literature that accumulated on this subject during th'e last fifty years. The appearance of the Russian edition of Dr. Fabelinskii's book, just as this laser-induced explosion in light-scattering research took place, served to put the earlier work in its proper perspective. However, the book lacked any appreci able coverage of the laser work. Fortunately, Dr. Fabelinskii has taken advantage of the time between the appearance of the Russian text and its translation into English to expand greatly the sections devoted to areas in which laser research has made such interesting and vital additions, At the same time, revisions and insertions have been made throughout the text, so that the English translation is virtually a second edition of this useful work. The translator wishes to express his thanks here to Dr. Fa belinskii for making the revisions, corrections, and additions availahle for the English language work. He is also grateful to his graduate student, Mark B. Moffett, who prepared the index and who, during the course of its preparation, made a large number of crit ical comments and corrections that have enhanced the quality of the final product.
Book Synopsis Light Scattering and Photon Correlation Spectroscopy by : E.R. Pike

This book was released on 2012-12-06 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since their inception more than 2.5 years ago, photon correlation techniques for the spatial, temporal or spectral analysis of fluctuating light fields have found an ever-widening range of applications. Using detectors which re spond to single quanta of the radiation field, these methods are intrinsically digital in natnre and in many experimental situations offer a unique degree of accuracy and sensitivity, not only for the study of primary light sources themselves, but most particularly in the use of a laser-beam probe to study light scattering from pure fluids, macromolecular suspensions and laminar or turbulent flowing fluids and gases. Following the earliest developments in laser scattering by dilute macro nl01ecular suspensions, in , ... hich particle sizing was the main aim, and the use of photon correlation techniques for laser-Doppler studies of flow and tnrbuence. both of which areas were the subject of NATO ASls in Capri, Italy in 19;:3 and 19;6. significant advances have be('n made in recent years in many other areas. These were reflected in the topics covered in this NATO Advanced Research Workshop, which took place from August 2;th to 30th, 1!)!}6, at the Jagiellonian University, Krakow, Poland. These in cluded ('xperimental techniques. statist.ics and data reduction, colloids and aggregation, polymers, gels, liquid crystals and mixtures, protein solutions, critical pllf'nomena and dense media.

This book was released on 2009-07-25 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fourth volume of Light Scattering Reviews is composed of three parts. The ?rstpartisconcernedwiththeoreticalandexperimentalstudiesofsinglelightsc- tering by small nonspherical particles. Light scattering by small particles such as, for instance, droplets in the terrestrial clouds is a well understood area of physical optics. On the other hand, exact theoretical calculations of light scattering p- terns for most of nonspherical and irregularly shaped particles can be performed only for the restricted values of the size parameter, which is proportional to the ratio of the characteristic size of the particle to the wavelength?. For the large nonspherical particles, approximations are used (e. g. , ray optics). The exact th- retical techniques such as the T-matrix method cannot be used for extremely large particles, such as those in ice clouds, because then the size parameter in the v- iblex=2?a/???,wherea is the characteristic size (radius for spheres), and the associated numerical codes become unstable and produce wrong answers. Yet another problem is due to the fact that particles in many turbid media (e. g. , dust clouds) cannot be characterized by a single shape. Often, refractive indices also vary. Because of problems with theoretical calculations, experimental (i. e. , la- ratory) investigations are important for the characterization and understanding of the optical properties of such types of particles. The ?rst paper in this volume, written by B. Gustafson, is aimed at the descr- tionofscaledanalogueexperimentsinelectromagneticscattering.
Book Synopsis Investigation of Crystal Imperfections by Means of Laser Light Scattering by : Richard Conger Powell
Download or read book Investigation of Crystal Imperfections by Means of Laser Light Scattering written by Richard Conger Powell and published by . This book was released on 1967 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of light scattering as a method for studying imperfections in crystals is discussed. A unique apparatus using a laser as a light source for ultramicroscopy and angular scattering experiments is described. The results obtained utilizing this apparatus for investigations of imperfections in ruby crystals are presented and discussed. These investigations were done as a function of crystal growth direction, annealing, boule morphology, polarization, chromium concentration, gamma-irradiation, and temperature. The results of this work demonstrate the usefulness of this new equipment as a convenient, nondestructive technique for characterizing imperfections in crystals of relatively large size. They also indicate the existence of both randomly distributed scatterers and oriented scattering regions in ruby crystals and show how these scattering centers are altered by changes in the various parameters studied in this investigation.

Book Synopsis Different Particle Size Information Obtained from Static and Dynamic Laser Light Scattering by : Yong Sun
Download or read book Different Particle Size Information Obtained from Static and Dynamic Laser Light Scattering written by Yong Sun and published by . This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Static light scattering (SLS) and dynamic light scattering (DLS) techniques are used to measure characteristics of particles in dispersion. SLS measures the dependence of the average scattered intensity I, on the scattering angle and is sensitive to spatial variations in the dielectric constant E. DLS measures the time dependence of the scattered light. One fundamental application of light scattering techniques is the accurate measurement of the size distribution of particles in dispersion. Detailed experimental investigation of SLS and DLS has been attempted in this work, with experimental work based on dilute water dispersions of two different spherical particles, polystyrene latexes and poly(N-isopropylacrylamide) (PNIPAM) microgels. Size information is obtained from SLS measurements in the form of a particle size distribution G (R,) where R, is the static radius. Size information is obtained from DLS measurements in the form of a decay rate distribution G (I?) which depends on the decay rate I?. Although both SLS and DLS can be used to obtain size information from the scattered light, the information obtained using SLS and DLS is different. For the three polystyrene latex sphere samples studied in this thesis, the mean static radii obtained are consistent with that of the mean radii provided by the supplier. For all three samples, the apparent hydrodynamic radius is larger than the mean static radius by about 12%. For PNIPAM microgel spheres, the apparent hydrodynamic radius is also larger than the mean static radius. The size of the PNIPAM microgel particles is extremely temperature sensitive; the radius decreases by a factor of three as the temperature is raised from 15OC to 50?? Both the hydrodynamic and static radii show this behavior. The effect of the chemical crosslinker (N, N'-methylenebisacrylamide) content on the temperature sensitivity of the PNIPAM microgels and the temperature dependence of the ratio of the apparent hydrodynamic radius to the mean static radius are also discussed.
