Methods Of X Ray And Neutron Scattering In Polymer Science

Also, to help students gain a unified view of diffraction, the distinction between wide-angle diffraction and small-angle scattering is postponed until late in the text."--BOOK JACKET.

Small-angle scattering of X rays and neutrons is a widely used diffraction method for studying the structure of matter. This method of elastic scattering is used in various branches of science and technology, includ ing condensed matter physics, molecular biology and biophysics, polymer science, and metallurgy. Many small-angle scattering studies are of value for pure science and practical applications. It is well known that the most general and informative method for investigating the spatial structure of matter is based on wave-diffraction phenomena. In diffraction experiments a primary beam of radiation influences a studied object, and the scattering pattern is analyzed. In principle, this analysis allows one to obtain information on the structure of a substance with a spatial resolution determined by the wavelength of the radiation. Diffraction methods are used for studying matter on all scales, from elementary particles to macro-objects. The use of X rays, neutrons, and electron beams, with wavelengths of about 1 A, permits the study of the condensed state of matter, solids and liquids, down to atomic resolution. Determination of the atomic structure of crystals, i.e., the arrangement of atoms in a unit cell, is an important example of this line of investigation.

This book is devoted to a simple practical approach to neutron, X-ray and light scattering experiments, involving model calculation of the scattering and mathematical transformation. It is intended to attract colloid and polymer scientists using scattering methods in their laboratory or at common research facilities. The primary objective is to explain the current methodology of elastic and quasi-elastic scattering techniques (avoiding both under and over-exploitation of data) rather than a general course on colloids and polymers. Basic information on data interpretation, on the complementarity of the different types of radiation, as well as information on recent applications and developments are presented.

Understanding and manipulating the properties of materials naturally occurring in our world and artificially produced by modern technologies requires detailed information on their properties on the atomic scale. This information is the basis for any kind of research in physics, chemistry, biology, engineering, metallurgy, and ceramics. Among the various experimental methods, neutron and photon scattering have become the key techniques of choice. This book provides an overview of the complementarity between neutron and synchrotron x-ray scattering. The most important topics are covered, including structure determination, magnetic correlations, polymer dynamics, thin films and multilayers, photoemission studies, etc; they are thoroughly introduced and discussed by experts from both the experimental and the theoretical side.

Nanostructure is in the focus of science, and advanced scattering methods are significantly contributing to the solution of related questions. This volume includes 19 contributions to the field of polymers and scattering, collected on the occasion of Wilhelm Ruland’s 80th anniversary in October 2005. The contributions from leading scientists cover a wide range of topics concerning -Advanced polymer materials -Studies of nanostructure: From bone to nanotubes -Modern data evaluation methods for isotropic and anisotropic scattering data. The book is an excellent source of information with respect to recent developments and future applications related to this important field that extends from the engineering of advanced materials to the development of novel evaluation methods.

Retaining its proven concept, the second edition of this ready reference specifically addresses the need of materials engineers for reliable, detailed information on modern material characterization methods. As such, it provides a systematic overview of the increasingly important field of characterization of engineering materials with the help of neutrons and synchrotron radiation. The first part introduces readers to the fundamentals of structure-property relationships in materials and the radiation sources suitable for materials characterization. The second part then focuses on such characterization techniques as diffraction and scattering methods, as well as direct imaging and tomography. The third part presents new and emerging methods of materials characterization in the field of 3D characterization techniques like three-dimensional X-ray diffraction microscopy. The fourth and final part is a collection of examples that demonstrate the application of the methods introduced in the first parts to problems in materials science. With thoroughly revised and updated chapters and now containing about 20% new material, this is the must-have, in-depth resource on this highly relevant topic.

Scattering experiments, using X-ray, light and neutron sources (in historical order) are key techniques for studying structure and dynamics in systems containing colliods, polymers, surfactants and biological macromolecules, summarized here as soft condensed matter. The education in this field in Europe is very heterogeneous and frequently inadequate, which severely limits an efficient use of these methods, especially at large-scale facilities. The series of "Bombannes" schools and the completely revised and updated second edition of the lecture notes are devoted to a practical approach to current methodology of static and dynamic techiques. Basic information on data interpretation, on the complementarity of the different types of radiation, as well as information on recent applications and developments is presented. The aim is to avoid over - as well as under-exploitation of data.

Neutrons, which are a penetrating yet non destructive probe, are ideally suited to studying the structure, organisation and motion of molecules responsible for the physical properties of materials under a variety of conditions. Applications are in fields as diverse as colloid and polymer science, earth sciences, pharmaceutics, biology and engineering. This book will be of interest to both present and potential future users of neutron sources working in these areas, as both a useful reference and a comprehensive overview.
