Abstract

This book highlights emerging diffraction studies of strain and dislocation gradients with mesoscale resolution, which is currently a focus of research at laboratories around the world. While ensemble-average diffraction techniques are mature, grain and subgrain level measurements needed to understand real materials are just emerging. In order to understand the diffraction signature of different defects, it is necessary to understand the distortions created by the defects and the corresponding changes in the reciprocal space of the non-ideal crystals. Starting with a review of defect classifications based on their displacement fields, this book then provides connections between different dislocation arrangements, including geometrically necessary and statistically stored dislocations, and other common defects and the corresponding changes in the reciprocal space and diffraction patterns. Subsequent chapters provide an overview of microdiffraction techniques developed during the last decade to extract information about strain and dislocation gradients. X-ray microdiffraction is a particularly exciting application compared with alternative probes of local crystalline structure, orientation and defect density, because it is inherently non-destructive and penetrating.

Abstract

X-ray astronomy is the prime available window on astrophysical compact objects: black holes, neutron stars and white dwarfs. New observational opportunities have led to an explosion of knowledge in this field. This book provides a comprehensive overview of the astrophysics of compact objects that emit X-rays. Sixteen chapters written by the foremost experts in the field cover the observations and the astrophysical interpretation of these objects. Topics covered include binary systems, gamma ray burst sources, anomalous X-ray pulsars, super-soft sources, and enigmatic fast X-ray transients. Further chapters are dedicated to isolated neutron stars and the X-ray source populations of globular clusters. The properties of X-ray binaries are discussed in depth in chapters on quasi-periodic oscillations and related aperiodic X-ray variability, X-ray bursts, black holes, and relativistic jets. This is a valuable reference for both graduate students and active researchers.

Abstract

The application of X-rays to archaeological objects with the goal of gaining insight into both their construction and chemical composition, in a non-destructive manner, dates back to the discovery of radiation. Nowadays, X-ray techniques, such as X-ray fluorescense and diffraction are standard tools. This book offers physicists, art historians, archaeologists, curators, and conservators a detailed overview via contributions written by leading scientists in the field. The book contains scientific data, i.e. in situ measurement data taken with portable XRF and XRD, and fine data taken with accelerating ion beams and synchrotron radiations, together with their explanations. Results obtained by traditional scientific methods are also reviewed. The broad data collection spans experimental data taken both from monuments in the field and exhibits in museums, for example: ancient Egyptian wall-painting pigments ancient Egyptian wooden statues and mummies ancient Greek funerary monuments Cypriot ceramics medieval, Lyubliana and Venetian glass Romanian ceramics ancient Near-Eastern clay old Japanese porcelain pre-Hispanic items from America ancient Chinese underglaze-red blue and white porcelain Chinese celadon Phoenician cosmetics Also included are data from glazes, ancient gold and silver coins, gold jewelleries, gold alloys, corroded metals, gemstones (ruby, emerald and garnet), painting pigments, pottery, bronze, obsidian, stucco, turquoise, and so on. The discussion fostered here between natural scientists and archaeologists anticipates the future direction of archaeology.

Abstract

The opportunities for doing scattering experiments at synchrotron and neutron facilities have grown rapidly in recent years and are set to continue to do so into the foreseeable future. This text provides a basic understanding of how these techniques enable the structure and dynamics of materials to be studied at the atomic and molecular level. Although mathematics cannot be avoided in a theoretical discussion, the aim has been to write a book that most scientists will still findapproachable. To this end, the first two chapters are devoted to providing a tutorial background in the mathematics

Abstract

The availability of synchrotron x-ray sources and the subsequent developments described in this book have led to substantial progress in our understanding of molecular ordering at liquid interfaces. This practical guide enables graduate students and researchers working in physics, chemistry, biology and materials science to understand and carry out experimental investigations into the basic physical and chemical properties of liquid surfaces and interfaces. The book examines the surfaces of bulk liquids, thin wetting films and buried liquid-liquid interfaces. It discusses experiments on simple and complex fluids, including pure water and organic liquids, liquid crystals, liquid metals, electrified liquid-liquid interfaces and interfacial monolayers of amphiphiles, nanoparticles, polymers and biomolecules. A detailed description of the apparatus and techniques required for these experiments is provided, and theoretical approaches to data analysis are described, including approximate methods such as the Master formula, the Born approximation, Parratt's algorithm and the Distorted Wave Approximation.

Abstract

Applications of X-ray scattering to soft matter have advanced considerably within recent years, both conceptually and technically – mature high-power X-ray sources, synchrotrons and rotating anodes, as well as high-speed detectors have become readily available. High-quality time-resolved experiments on polymer structure now can be performed with ease, a major advancement due to the genuine power of the scattering method. This manual summarizes the analytical power of modern X-ray scattering in the field of soft matter. Description of simple tools that can elucidate the mechanisms of structure evolution in the studied materials is followed by a step-by-step guide and breakdown of the more advanced methods. Data analysis based on clear, unequivocal results is rendered simple and straightforward – with a stress on the carefully planning of the experiments and adequate recording of all required data. To this end, this book serves as a useful ready-reference guide.
