Available in PDF, EPUB and Kindle. Book excerpt: This open access book, edited and authored by a team of world-leading researchers, provides a broad overview of advanced photonic methods for nanoscale visualization, as well as describing a range of fascinating in-depth studies. Introductory chapters cover the most relevant physics and basic methods that young researchers need to master in order to work effectively in the field of nanoscale photonic imaging, from physical first principles, to instrumentation, to mathematical foundations of imaging and data analysis. Subsequent chapters demonstrate how these cutting edge methods are applied to a variety of systems, including complex fluids and biomolecular systems, for visualizing their structure and dynamics, in space and on timescales extending over many orders of magnitude down to the femtosecond range. Progress in nanoscale photonic imaging in Göttingen has been the sum total of more than a decade of work by a wide range of scientists and mathematicians across disciplines, working together in a vibrant collaboration of a kind rarely matched. This volume presents the highlights of their research achievements and serves as a record of the unique and remarkable constellation of contributors, as well as looking ahead at the future prospects in this field. It will serve not only as a useful reference for experienced researchers but also as a valuable point of entry for newcomers.

Download or read book Short Wavelength Laboratory Sources written by Alan Michette and published by Royal Society of Chemistry. This book was released on 2014-12-15 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our ability to manipulate short wavelength radiation (0.01-100nm, equivalent to 120keV-12eV) has increased significantly over the last three decades. This has lead to major advances in applications in a wide range of disciplines such as: the life and medical sciences, including cancer-related studies; environmental science, including studies of pollution and its effects; archaeology and other cultural heritage disciplines; and materials science. Although expansion in application areas is due largely to modern synchrotron sources, many applications will not become widespread, and therefore routinely available as analytical tools, if they are confined to synchrotrons. This is because synchrotrons require enormous capital and infrastructure costs and are often, of necessity, national or international facilities. This seriously limits their scope for applications in research and analysis, in both academia and industry. How many universities, research institutes or even industrial laboratories would have electron microscopes if electron sources cost ú100M or more Hence the need to develop bright but small and (relatively) cheap x-ray sources, not to replace synchrotrons but to complement them. Written by a distinguished team of international authors this exemplary new handbook is based on the COST Action MP0601: Short Wavelength Laboratory Sources. The contents are divided into five main sections. The introductory section provides a comprehensive introduction to the fundamentals of radiation, generation mechanisms and short wavelength laboratory sources. The middle sections focus on modelling and simulation, source development: improvement and characterisation and integrated systems: sources, optics and detectors. The final section looks at recent applications.
Download or read book Inference from Incomplete Data in Coherent Diffraction Imaging written by Sara Salha and published by . This book was released on 2014 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in nanotechnology and biotechnology are propelled by our ability to manipulate and resolve the structure of matter on fine scales. As imaging at higher resolution is limited by the probing light source and the numerical aperture, lensless imaging offers an advantage over lensed microscopy. Dispensing with lenses allows one to overcome certain intrinsic aberrations and to bypass fabrication costs, in the optical and the X-ray regimes. The long penetration depth of X-rays renders coherent X-ray diffraction imaging (CXDI) the method of choice for high resolution structure determination with broad applications from materials science to biology; moreover, the same methodology is extensible to electrons, optical photons, or even gamma rays or neutrons. Since coherent diffraction imaging (CDI) bypasses the need for focusing optics, it relies upon computer algorithms to reconstruct the structure of the scattering object. Currently, one of the main obstacles to nanometer resolution of biological imaging is noisy, incomplete data due to radiation damage. With the rapid development of new light source facilities and the advancement in image reconstruction techniques, determining the structure of individual virons or cells at high resolution is becoming more feasible. In particular, the femtosecond pulse of a free electron laser (FEL) is shorter than the coulomb explosion of the specimen, and thus, it is possible to collect diffraction data prior to radiation damage. However, to fully exploit the computational aspect of lensless imaging, prior knowledge about the object should be incorporated into the image reconstruction process and yet so far such methods are generally lacking. In this thesis, we develop tools that incorporate prior knowledge and reduce the amount of necessary data to recover the structure. We begin by a brief overview of lensless imaging and its place in the natural sciences. we then review the process of image formation in coherent X-ray scattering, the corresponding phase problem and the current state of image recovery. The contributions to this field are two fold. We first demonstrate that three dimensional information can be extracted from a two dimensional diffraction pattern collected at a high numerical aperture. Second, we present a framework for image discovery through Bayesian inference, where we introduce four general constraints: symmetry, sparsity and bounded local and total variation. Using simulated noisy, incomplete data, we recover the solution in situations where traditional algorithms fail. We anticipate that these results will encourage the broader application of Bayesian learning into the phase retrieval problem from noisy, incomplete diffraction data and further enhance the possibility of single shot three dimensional structure determination.

Available in PDF, EPUB and Kindle. Book excerpt: This text is a companion volume to Transmission Electron Microscopy: A Textbook for Materials Science by Williams and Carter. The aim is to extend the discussion of certain topics that are either rapidly changing at this time or that would benefit from more detailed discussion than space allowed in the primary text. World-renowned researchers have contributed chapters in their area of expertise, and the editors have carefully prepared these chapters to provide a uniform tone and treatment for this exciting material. The book features an unparalleled collection of color figures showcasing the quality and variety of chemical data that can be obtained from today’s instruments, as well as key pitfalls to avoid. As with the previous TEM text, each chapter contains two sets of questions, one for self assessment and a second more suitable for homework assignments. Throughout the book, the style follows that of Williams & Carter even when the subject matter becomes challenging—the aim is always to make the topic understandable by first-year graduate students and others who are working in the field of Materials Science Topics covered include sources, in-situ experiments, electron diffraction, Digital Micrograph, waves and holography, focal-series reconstruction and direct methods, STEM and tomography, energy-filtered TEM (EFTEM) imaging, and spectrum imaging. The range and depth of material makes this companion volume essential reading for the budding microscopist and a key reference for practicing researchers using these and related techniques.

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.
