Available in PDF, EPUB and Kindle. Book excerpt: One of the few textbooks in the field, this volume deals with several aspects of the dynamics of colloids. A self-contained treatise, it fills the gap between research literature and existing books for graduate students and researchers. For readers with a background in chemistry, the first chapter contains a section on frequently used mathematical techniques, as well as statistical mechanics. Some of the topics covered include: • diffusion of free particles on the basis of the Langevin equation •the separation of time, length and angular scales; • the fundamental Fokker-Planck and Smoluchowski equations derived for interacting particles • friction of spheres and rods, and hydrodynamic interaction of spheres (including three body interactions) • diffusion, sedimentation, critical phenomena and phase separation kinetics • experimental light scattering results. For universities and research departments in industry this textbook makes vital reading.
Download or read book Dynamic Light Scattering written by R. Pecora and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the twenty years since their inception, modern dynamic light-scattering techniques have become increasingly sophisticated, and their applications have grown exceedingly diverse. Applications of the techniques to problems in physics, chemistry, biology, medicine, and fluid mechanics have prolifer ated. It is probably no longer possible for one or two authors to write a monograph to cover in depth the advances in scattering techniques and the main areas in which they have made a major impact. This volume, which we expect to be the first of aseries, presents reviews of selected specialized areas by renowned experts. It makes no attempt to be comprehensive; it emphasizes a body of related applications to polymeric, biological, and colloidal systems, and to critical phenomena. The well-known monographs on dynamic light scattering by Berne and Pecora and by Chu were published almost ten years ago. They provided comprehensive treatments of the general principles of dynamic light scat tering and gave introductions to a wide variety of applications, but natu rally they could not treat the new applications and advances in older ones that have arisen in the last decade. The new applications include studies of interacting particles in solution (Chapter 4); scaling approaches to the dynamics of polymers, including polymers in semidilute solution (Chapter 5); the use of both Fabry-Perot interferometry and photon correlation spectroscopy to study bulk polymers (Chapter 6); studies of micelIes and microemulsions (Chapter 8); studies of polymer gels (Chapter 9).
Download or read book Introduction to Dynamic Light Scattering by Macromolecules written by Kenneth S Schmitz and published by Elsevier. This book was released on 2012-12-02 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Dynamic Light Scattering by Macromolecules provides an introduction to the basic concepts of dynamic light scattering (DLS), with an emphasis on the interpretation of DLS data. It presents the appropriate equations used to interpret DLS data. The material is presented in order of increasing complexity of the systems under examination, ranging from dilute solutions of noninteracting particles to concentrated multicomponent solutions of strongly interacting particles and gels. Problems are presented at the end of each chapter to emphasize these concepts. Since a major emphasis of this textbook is the interpretation of DLS data obtained by polarized light scattering studies on macromolecular solutions, the results of complementary experimental techniques are also presented in order to gain insight into the dynamics of these systems. This textbook is intended for (1) advanced undergraduate students and graduate students in the chemical, physical, and biological sciences; (2) scientists who might wish to apply DLS methods to systems of interest to them but who have no formal training in the field of DLS; and (3) those who are simply curious as to the type of information that might be obtained from DLS techniques.
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.

This book was released on 2012-12-06 with total page 848 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, various powerful experimental tools have been developed, such as small angle X-ray and neutron scattering, X-ray and neutron reflection from interfaces, neutron spin-echo spectroscopy and quasi-elastic multiple light scattering and large scale computer simulations. Due to the rapid progress brought about by these techniques, one witnesses a resurgence of interest in the physicochemical properties of colloids, surfactants and macromolecules in solution. Although these disciplines have a long history, they are at present rapidly transforming into a new, interdisciplinary research area generally known as complex liquids or soft condensed matter physics: names that reflect the considerable involvement of the chemical and condensed matter physicists. This book is based on lectures given at a NATO ASI held in the summer of 1991 and discusses these new developments, both in theory and experiment. It constitutes the most up-to-date and comprehensive summary of the entire field.

This book was released on 2012-12-06 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains most of the papers presented at the "Workshop on Quasielastic Light Scattering Studies of Fluids and Macromolecular Solutions" held at CISE, Segrate (Milano), Italy, from 11 to 13 May, 1979. Quasielastic light scattering (also called self-beating spectroscopy or intensity correlation spectroscopy) is the technique, introduced by Benedek and coworkers and by Cummins and coworkers about 15 years ago, by which dynamical information about a scattering medium is obtained through the measurement of the power spectrum (or the intensity correlation function) of the laser light scattered from the medium. The technique received in the early seventies a considerable impulse from the development of real-time fast digital correlators. The aim of the Workshop was to bring together a selected number of researchers in order to discuss recent developments in quasielastic light scattering and related optical methods and to report about new applications of the technique in physics, chemistry and biology. The first two days of the meeting were devoted to the oral presentations of papers. In the third day an informal session was held which included a very lively and thorough discussion of the highlights of the Workshop. Most part of the technical problems were debated during the informal session and during the subsequent visits to the light scattering laboratory in CISE.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The Fourth USA-USSR Symposium. on The Physics of Optical Phenomena and Their Use as Probes of Matter, was held in Irvine, California, January 23-27, 1990. Participating in the Symposium were 22 scientists from the USSR and 29 from the USA. In addition, to provide an international dimension to this Symposium without, however, compromising significantly its essentially binational character, 7 non-US and non-USSR scientists were invited to take part in it. The present volume is the proceedings of that Symposium, and contains all manuscripts received prior to August 1, 1990, representing. scientific contributions presented. A few manuscripts were not received, but for completeness the corresponding abstract is printed.. Three previous USA/USSR Binational Symposia on related topics have been held, viz. "Theory of Light Scattering in Condensed Matter" (Moscow, 1975), "Light Scattering in Solids" (New York, 1979), and "Laser Optics of Condensed Matter" (Leningrad, 1987). These meetings were evaluated by the participants as highly successful and provided invaluable oppor tunities for researchers to exchange information and to initiate colla borative work which led to research visits by US physicist to Soviet laboratories, and vice versa, and which continue to the present day.

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.
Download or read book An Improved Form for the Electrostatic Interactions of Polyelectrolytes in Solution and Its Implications for the Analysis of QELSS Experiments in Sodium Dodecyl Sulfate and Cetyl Trimethyl Ammonium Bromide written by Nicholas V. Sushkin and published by Universal-Publishers. This book was released on 1997-11 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electrostatic interaction between two charged spheres in the presence of a screening electrolyte is calculated at the level of the linearized Debye-Hückel theory. The calculation is performed analytically as a multipole expansion by applying two-center spherical harmonic expansions and symbolic manipulation methods. I focus on charge-charge and charge-induced dipole interactions, calculated for two spheres of possibly unequal size. The former interaction is given to good approximation by the familiar Debye-Hückel form q1q2exp[-k(R-2a)]/[(epsilon*r(1]ka)^2]. The new results are the charge-induced dipole interactions. Physically, these terms arise from two sources: (i) surface polarization charge at the surface of each sphere, and (ii) exclusion of the counterion cloud of each sphere from the volume occupied by the other sphere. With parameters appropriate for micelles, the charge-induced dipole interactions dominate the charge-charge interaction at small separations. Quasi-elastic light scattering measurements of the diffusion of sodium dodecyl sulfate (SDS) and cetyl trimethyl ammonium bromide (CTAB) micelles in aqueous solutions, and the diffusion of mesoscopic optical probes through the same solutions, were carried out at 35°C and multiple solvent ionic strengths. Assuming a spherical micelle, I deduced the micelle radius, aggregation number, charge, and hydration from nonlinear least-squares fits to both probe and mutual diffusion data. For SDS micelles the charge that I find is lower than reported in the literature [Hayter, J. B.; Penfold, J. Colloid & Polymer Science 1983, 261, 1022; Triolo, R.; Caponetti, E.; Graziano, V. J. Phys. Chem. 1985, 89, 5743.] because I used an improved functional form of the micellar electrostatic interaction. I find a smaller aggregation number and a larger micellar hydration than literature values. My analysis of CTAB data implies extensive micellar growth, and failure of the spherical micelle assumption.
