Neutrons in Soft Matter


Book Description

Neutron and synchrotron facilities, which are beyond the scale of the laboratory, and supported on a national level in countries throughout the world. These tools for probing micro- and nano-structure research and on fast dynamics research of atomic location in materials have been key in the development of new polymer-based materials. Different from several existing professional books on neutron science, this book focuses on theory, instrumentation, an applications. The book is divided into five parts: Part 1 describes the underlying theory of neutron scattering. Part 2 describes the various instruments that exist and the various techniques used to achieve neutron scattering or bombardment. Part 3 discusses data treatment and simulation methods as well as how to assess the environment of the sample (temperature, pressure, shear, and external fields). Part 4 addresses the myriad applications of small and large molecules, biomolecules, and gels. Part 5 describes the various global neutron sources that exist and provides an overview of the different reactors.




Dynamics of Soft Matter


Book Description

Dynamics of Soft Matter: Neutron Applications provides an overview of neutron scattering techniques that measure temporal and spatial correlations simultaneously, at the microscopic and/or mesoscopic scale. These techniques offer answers to new questions arising at the interface of physics, chemistry, and biology. Knowledge of the dynamics at these levels is crucial to understanding the soft matter field, which includes colloids, polymers, membranes, biological macromolecules, foams, emulsions towards biological & biomimetic systems, and phenomena involving wetting, friction, adhesion, or microfluidics. Emphasizing the complementarities of scattering techniques with other spectroscopic ones, this volume also highlights the potential gain in combining techniques such as rheology, NMR, light scattering, dielectric spectroscopy, as well as synchrotron radiation experiments. Key areas covered include polymer science, biological materials, complex fluids and surface science.




Applications of Neutron Scattering to Soft Condensed Matter


Book Description

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.




Neutrons, X-rays, and Light


Book Description

This book addresses the possibilities provided by scattering techniques in the study of soft matter. It fills the gap between the fundamental scattering processes, which are described by the general theoretical framework of elastic and quasi-elastic interaction of radiation with matter, and state-of-the-art applications to specific soft matter systems. Three probes are discussed in detail: neutrons, X-ray photons, and visible light. The first part of the book is dedicated to the use of general principles for the measurement and analysis of scattered intensity: elementary scattering process, data reduction, general theorems, the concept of reciprocal space, and its link to structural and dynamical information in direct space. In the second part, methods and techniques are further discussed, including resolution effects, contrast variation, static and dynamic light scattering, quasi-elastic neutron scattering, and reflectometry and grazing incidence techniques. Part three deals with the state of the art of scattering studies of typical soft matter systems (polymers, self-assembled surfactant systems, microemulsions, liquid crystals, colloids, aggregates, biological systems) with dedicated chapters for particle interactions, and modelling. Part four highlights special applications, from turbid media to scattering under external constraints, and industrial applications. This new edition, written by the lecturers of the Bombannes Summer School, will be most useful as a learning tool for masters and PhD students, post-docs, and young researchers moving into the field. As with the previous edition, it will also be a reference for any scientist working in soft matter, where scattering techniques are ubiquitous, used both in small laboratories and at large-scale research facilities. • Provides an understandable and thorough introduction to the fundamentals of scattering in a way that is accessible for students/PhDs.• Offers a comprehensive overview of the main scattering techniques associated with neutrons, X-rays, and light.• Includes chapters on virtually all soft matter systems.• Presents both standard analyses and recent advances in scattering techniques

Neutron Scattering in Condensed Matter Physics


Book Description

Neutron scattering has become a key technique for investigating the properties of materials on an atomic scale. The uniqueness of this method is based on the fact that the wavelength and energy of thermal neutrons ideally match interatomic distances and excitation energies in condensed matter, and thus neutron scattering is able to directly examine the static and dynamic properties of the material. In addition, neutrons carry a magnetic moment, which makes them a unique probe for detecting magnetic phenomena. In this important book, an introduction to the basic principles and instrumental aspects of neutron scattering is provided, and the most important phenomena and materials properties in condensed matter physics are described and exemplified by typical neutron scattering experiments, with emphasis on explaining how the relevant information can be extracted from the measurements.




Soft-Matter Characterization


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.




Condensed Matter Research Using Neutrons


Book Description

The Advanced Research Workshop (ARW) on Condensed Matter Re search Using Neutrons, Today and Tomorrow was held in Abingdon, Oxfordshire for four days beginning 26 March 1984. The Workshop was sponsored by NATO and the Rutherford Appleton Laboratory. A total of 32 lecturers and participants attended. An objective of the Workshop was to review some dynamic proper ties of condensed matter that can be studied using neutron spectros copy. A second objective, no less important, was to identify new topics that might be investigated with advanced spallation neutron sources. The twelve lectures reproduced in this volume bear wit ness, largely by themselves, to the success of the Workshop in meet ing these objectives. The many discussions generated by lecturers and participants meant that, in the event, the objectives were in deed amply satisfied. I should like to thank all those who attended the Horkshop for their part in making it so beneficial and rewarding. I am most grateful to Reinhard Scherm, who acted as my advisor in the organisation of the Workshop. The efforts of Mrs. M. Sherwen and Miss J. Harren made light my burden of administrative duties. The preparation of the manuscript for publication was simplified by the assistance of Miss C. Monypenny.




Vibrational Spectroscopy With Neutrons - With Applications In Chemistry, Biology, Materials Science And Catalysis


Book Description

Inelastic neutron scattering (INS) is a spectroscopic technique in which neutrons are used to probe the dynamics of atoms and molecules in solids and liquids. This book is the first, since the late 1960s, to cover the principles and applications of INS as a vibrational-spectroscopic technique. It provides a hands-on account of the use of INS, concentrating on how neutron vibrational spectroscopy can be employed to obtain chemical information on a range of materials that are of interest to chemists, biologists, materials scientists, surface scientists and catalyst researchers. This is an accessible and comprehensive single-volume primary text and reference source.
