Book Synopsis Studying Atomic Dynamics with Coherent X-rays by : Michael Leitner
Download or read book Studying Atomic Dynamics with Coherent X-rays written by Michael Leitner and published by Springer Science & Business Media. This book was released on 2012-01-04 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diffusion in solids at moderate temperatures is a well-known phenomenon. However, direct experimental evidence about the responsible atomic-scale mechanisms has been scarce, due to difficulties in probing the relevant length- and time-scales. The present thesis deals with the application of X-ray Photon Correlation Spectroscopy (XPCS) for answering such questions. This is an established method for the study of slow dynamics on length-scales of a few nanometres. The scattered intensity in the diffuse regime, i.e. corresponding to atomic distances, is very low, however, and so it has so far been considered impossible to use XPCS for this problem. Threefold progress is reported in this work: It proposes a number of systems selected for high diffuse intensity, it optimizes the photon detection and data evaluation procedures, and it establishes theoretical models for interpretating the results. Together these advances allowed the first successful atomic-scale XPCS experiment, which elucidated the role of preferred configurations for atomic jumps in a copper-gold alloy. The growth in available coherent X-ray intensity together with next-generation X-ray sources will open up a wide field of application for this new method.

Book Synopsis Material Research in Atomic Scale by Mössbauer Spectroscopy by : Miroslav Mashlan
Download or read book Material Research in Atomic Scale by Mössbauer Spectroscopy written by Miroslav Mashlan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mössbauer spectroscopy is uniquely able to probe hyperfine interactions by looking at the short-range order of resonant atoms. Materials containing an appropriate isotope as one of their constituent atoms, such as iron or tin, are readily investigated. But even materials that do not contain Mössbauer-active atoms can be investigated if the probe atoms are incorporated in minor quantities (ca. 0.1 at.-%) to act as molecular-level indicators. These 35 papers collected here represent a state-of-the-art description of Mössbauer spectroscopy techniques applied to advanced materials. The topics covered comprise investigations of nanomaterials, nanoparticles, and quasicrystals, artificially structured materials as well as applications of Mössbauer spectroscopy in chemistry, mineralogy and metallurgy. The main aim of is the dissemination of information on research and recent developments of the method in materials science as obtained in leading Mössbauer laboratories.

Book Synopsis Light Scattering and Photon Correlation Spectroscopy by : E.R. Pike
Download or read book Light Scattering and Photon Correlation Spectroscopy written by E.R. Pike and published by Springer Science & Business Media. 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. Following the earliest developments in laser scattering by dilute macro nl01ecular suspensions, in , ... hich particle sizing was the main aim, and the use of photon correlation techniques for laser-Doppler studies of flow and tnrbuence. both of which areas were the subject of NATO ASls in Capri, Italy in 19;:3 and 19;6. significant advances have be('n made in recent years in many other areas. These were reflected in the topics covered in this NATO Advanced Research Workshop, which took place from August 2;th to 30th, 1!)!}6, at the Jagiellonian University, Krakow, Poland. These in cluded ('xperimental techniques. statist.ics and data reduction, colloids and aggregation, polymers, gels, liquid crystals and mixtures, protein solutions, critical pllf'nomena and dense media.

Book Synopsis Synchrotron Light Sources and Free-Electron Lasers by : Eberhard J. Jaeschke
Download or read book Synchrotron Light Sources and Free-Electron Lasers written by Eberhard J. Jaeschke and published by Springer. This book was released on 2016-05-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardly any other discovery of the nineteenth century did have such an impact on science and technology as Wilhelm Conrad Röntgen’s seminal find of the X-rays. X-ray tubes soon made their way as excellent instruments for numerous applications in medicine, biology, materials science and testing, chemistry and public security. Developing new radiation sources with higher brilliance and much extended spectral range resulted in stunning developments like the electron synchrotron and electron storage ring and the freeelectron laser. This handbook highlights these developments in fifty chapters. The reader is given not only an inside view of exciting science areas but also of design concepts for the most advanced light sources. The theory of synchrotron radiation and of the freeelectron laser, design examples and the technology basis are presented. The handbook presents advanced concepts like seeding and harmonic generation, the booming field of Terahertz radiation sources and upcoming brilliant light sources driven by laser-plasma accelerators. The applications of the most advanced light sources and the advent of nanobeams and fully coherent x-rays allow experiments from which scientists in the past could not even dream. Examples are the diffraction with nanometer resolution, imaging with a full 3D reconstruction of the object from a diffraction pattern, measuring the disorder in liquids with high spatial and temporal resolution. The 20th century was dedicated to the development and improvement of synchrotron light sources with an ever ongoing increase of brilliance. With ultrahigh brilliance sources, the 21st century will be the century of x-ray lasers and their applications. Thus, we are already close to the dream of condensed matter and biophysics: imaging single (macro)molecules and measuring their dynamics on the femtosecond timescale to produce movies with atomic resolution.

Book Synopsis Devitrification of Bulk Metallic Glasses Studied by Neutron and X-ray Scattering by : Ling Yang
Download or read book Devitrification of Bulk Metallic Glasses Studied by Neutron and X-ray Scattering written by Ling Yang and published by . This book was released on 2006 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: The structural evolutions during the devitrification of three bulk metallic glasses, including Zr52.5Cu17.9Ni 14.6Al10Ti5 (BAM-11), Zr50Cu40 Al10 and Mg65Cu25Tb10, have been studied in-situ by neutron and synchrotron X-ray scattering. By measuring simultaneously the wide-angle X-ray scattering (WAXS) patterns and the small-angle X-ray scattering (SAXS) patterns, a good comparison of the structural evolutions at the atomic scale and nano scales during the different transformation stages are achieved. Also the evolutions of pair distribution functions (PDFs) in real space have been measured by neutron and X-ray total scattering. These results are further complemented by ex-situ experiments including DSC, conventional XRD, TEM and SEM. The results show all three samples are amorphous in the as-cast state, and that phase separation precedes crystallization for Zr-based BMGs. BAM-11 devitrifies in two stages; the first stage is related to topological changes within a 2 nm range, and a metastable fcc NiZr2 phase is formed, which transforms to the tetragonal NiZr2 phase in the second stage. Above 690 K, Zr50Cu40Al10 decomposes to form the Cu10Zr7 phase and CuZr2 phase, which transform to the CuZr phase eutectoidly at higher temperature. Mg65Cu 25Tb10 devitrifies in three stages, the first stage is related to the formation of icosahedral clusters, the second and third stages are the formation of quasicrystalline phase and further decomposition. Kinetic model and SAXS model are proposed and applied to refine the patterns. The topologies of conventional oxide glasses and BMGs are compared and summarized. The nonperiodic order plays an important role in nanometer scale for BMGs.
