Book Description
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.

Book Description
Advanced Characterization of Nanostructured Materials — Probing the Structure and Dynamics with Synchrotron X-Rays and Neutrons is a collection of chapters which review the characterization of the structure and internal dynamics of a wide variety of nanostructured materials using various synchrotron X-ray and neutron scattering techniques. It is intended for graduate students and researchers who might be interested in learning about and applying these methods. The authors are well-known practitioners in their fields of research who provide detailed and authoritative accounts of how these techniques have been applied to study systems ranging from thin films and monolayers on solid surfaces and at liquid-air, liquid-liquid and solid-liquid interfaces; nanostructured composite materials; battery materials, and catalytic materials. While there have been a great many books published on nanoscience, there are relatively few that have discussed in one volume detailed synchrotron X-ray and neutron methods for advanced characterization of nanomaterials in thin films, composite materials, catalytic and battery materials and at interfaces. This book should provide an incentive and a reference for researchers in nanomaterials for using these techniques as a powerful way to characterize their samples. It should also help to popularize the use of synchrotron and neutron facilities by the nanoscience community.

Book Description
Very thin film materials have emerged as a highly interesting and useful quasi 2D-state functionality. They have given rise to numerous applications ranging from protective and smart coatings to electronics, sensors and display technology as well as serving biological, analytical and medical purposes. The tailoring of polymer film properties and functions has become a major research field. As opposed to the traditional treatise on polymer and resin-based coatings, this one-stop reference is the first to give readers a comprehensive view of the latest macromolecular and supramolecular film-based nanotechnology. Bringing together all the important facets and state-of-the-art research, the two well-structured volumes cover film assembly and depostion, functionality and patterning, and analysis and characterization. The result is an in-depth understanding of the phenomena, ordering, scale effects, fabrication, and analysis of polymer ultrathin films. This book will be a valuable addition for Materials Scientists, Polymer Chemists, Surface Scientists, Bioengineers, Coatings Specialists, Chemical Engineers, and Scientists working in this important research field and industry.

Book Description
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 Description
This 2-volume set includes extensive discussions of scattering techniques (light, neutron and X-ray) and related fluctuation and grating techniques that are at the forefront of this field. Most of the scattering techniques are Fourier space techniques. Recent advances have seen the development of powerful direct imaging methods such as atomic force microscopy and scanning probe microscopy. In addition, techniques that can be used to manipulate soft matter on the nanometer scale are also in rapid development. These include the scanning probe microscopy technique mentioned above as well as optical and magnetic tweezers.

Book Description
The study of the relationship between the structure, morphology and properties of polymer films has significantly progressed in recent years through the use of a number of phyiscal techniques - some new and some old. These methods include small and large angle x-ray diffraction, bire fringence, light scattering, infrared dichroism, fluorescence polarization, light and electron microscopy and interferrometry. This collection of papers, most of which were presented at a symposium at the Boston American Chemical Society Meeting in April, 1972, represent a collection of recent studies using many of these methods by some of the leading scientists in their fields. It is evident that these various techniques permit the study of various aspects of film structure such as crystal structure and orientation, amorphous orientation, the interrelation of crystalline and amorphous regions in lamellar, fibrillar, and spherulitic superstructure and the relationshi. p of these structural variables to the mechanical and optical properties of the films. Film structure is sufficiently complex that a complete understanding of the relationship between structure and properties will come from the employment of a combination of several of these methods. vii CONTENTS Optical Studies of the Morphology of Polymer Films ••• • • 1 Richard S.

Book Description
Smart Stimuli-Responsive Poymers, Films, and Gels Discover the most important developments in synthesis, simulation, and applications of a fascinating compound class There exist a range of natural materials that respond to environmental changes by altering their physical or chemical properties, known as stimuli-responsive polymers, these substances are responsive to light, temperature, pressure, and more. The study of these so-called “smart” polymers is essential to a range of application fields, many of which have generated cutting-edge research in recent decades. A comprehensive introduction to the subject is therefore well-timed Smart Stimuli-Responsive Polymers, Films, and Gels provides an introduction to these polymers and their applications. It includes producing these polymers through synthetic approaches, simulating their responses to different stimuli, and applying these materials in different industries and research capacities. Written to serve the requirements of advanced students and senior researchers alike, this timely work will drive years of research in this vital field. In Smart Stimuli-Responsive Polymers, Films, and Gels readers will also find: Treatment of mechanoresponsive, photoresponsive, and ionizing-radiation responsive polymers Applications in emerging fields such as sensors, biomedicine, catalysis, and more Interdisciplinary research into the properties and responses of these vital compounds Smart Stimuli-Responsive Polymers, Films, and Gels promises to become a seminal work for chemists, materials scientists, and industrial researchers seeking to incorporate these materials into a variety of industrial and research areas.

Book Description
This book serves as a teaching tool for beginning graduate students and new researchers interested in two seemingly divergent themes whereby one theme deals with synchrotron X-ray scattering and laser cross correlation function techniques, while the other theme is concerned mainly with the use of electrospun nanofibers for application to water purification. Together with recent reviews of several hundreds of references on the two themes, the monograph points out how we should adapt our education to new environments in the changing society.
