Available in PDF, EPUB and Kindle. Book excerpt: Microscopic X-ray Fluorescence Analysis Edited by Koen H. A. Janssens, Freddy C. V. Adams Department of Chemistry, University of Antwerp, Belgium and Anders Rindby Department of Physics, Chalmers University of Technology, Göteborg, Sweden In the last 10-15 years many analytical advances in X-ray fluorescence analysis (XRF) have taken place, giving rise to non-destructive ultrasensitive surface analyses of materials. One of the variants of XRF developed is micro-XRF (μ-XRF), which is able to analyse the distribution of major, minor and trace elements in microscopic sample surface areas. Due to the availability of commercial instrumentation and the development of simple devices for focusing X-rays, μ-XRF has increased in popularity and is able to fill the gap between bulk X-ray fluorescence and electron probe X-ray microanalysis (EPXMA). Microscopic X-ray Fluorescence Analysis is the first single volume to bring together introductory and advanced information on the essential aspects of the technique, thereby providing an excellent overview of the developments and applications of μ-XRF. Topics discussed in the book include: * Interaction of X-rays with matter * Micro-focusing X-ray optics * Instrumentation for μ-XRF with laboratory and synchrotron sources * Evaluation and calibration of μ-XRF data * Comparison of μ-XRF to other microanalytical techniques. In addition, the final chapters of the book describe applications of μ-XRF in the geosciences, in art and archaeology, environmental and biological applications, and the use of μ-XRF for industrial purposes. Finally an overview is presented of some of the new directions both laboratory and synchrotron μ-XRF are likely to take in the 21st Century.

Book excerpt: This book has its origins in the intensive short courses on scanning elec tron microscopy and x-ray microanalysis which have been taught annually at Lehigh University since 1972. In order to provide a textbook containing the materials presented in the original course, the lecturers collaborated to write the book Practical Scanning Electron Microscopy (PSEM), which was published by Plenum Press in 1975. The course con tinued to evolve and expand in the ensuing years, until the volume of material to be covered necessitated the development of separate intro ductory and advanced courses. In 1981 the lecturers undertook the project of rewriting the original textbook, producing the volume Scan ning Electron Microscopy and X-Ray Microanalysis (SEMXM). This vol ume contained substantial expansions of the treatment of such basic material as electron optics, image formation, energy-dispersive x-ray spectrometry, and qualitative and quantitative analysis. At the same time, a number of chapters, which had been included in the PSEM vol ume, including those on magnetic contrast and electron channeling con trast, had to be dropped for reasons of space. Moreover, these topics had naturally evolved into the basis of the advanced course. In addition, the evolution of the SEM and microanalysis fields had resulted in the devel opment of new topics, such as digital image processing, which by their nature became topics in the advanced course.

Available in PDF, EPUB and Kindle. Book excerpt: This book has grown out of our shared experience in the development of the Stanford Synchrotron Radiation Laboratory (SSRL), based on the electron-positron storage ring SPEAR at the Stanford Linear Accelerator Center (SLAC) starting in Summer, 1973. The immense potential of the photon beam from SPEAR became obvious as soon as experiments using the beam started to run in May, 1974. The rapid growth of interest in using the beam since that time and the growth of other facilities using high-energy storage rings (see Chapters 1 and 3) demonstrates how the users of this source of radiation are finding applications in an increasingly wide variety of fields of science and technology. In assembling the list of authors for this book, we have tried to cover as many of the applications of synchrotron radiation, both realized already or in the process of realization, as we can. Inevitably, there are omissions both through lack of space and because many projects are at an early stage. We thank the authors for their efforts and cooperation in producing what we believe is the most comprehensive treatment of synchrotron radiation research to date.

Available in PDF, EPUB and Kindle. Book excerpt: X-ray Optics and X-ray Microanalysis covers the proceedings of the Symposium on X-ray Optics and X-ray Microanalysis, held at Stanford University on August 22-24, 1962. The book focuses on X-ray microscopy, microradiography, radiation and irradiation, and X-ray microanalysis. The selection first offers information on the methods of X-ray microscopy and X-ray absorption microanalysis. Discussions focus on X-ray scanning microscopy, contact microradiography, point projection microscopy, and total dry-weight determinations. The text then takes a look at X-ray microanalysis in biology and medicine; electron microscopic enlargements of X-ray absorption micrographs; and automation in microradiography. The publication examines the production of Fresnel zone plates for extreme ultraviolet and soft X radiation; quantitative microradiographic studies of human epidermis; and irradiation effect on total organic nerve-cell material determined by integrating X-ray absorption. The manuscript then reviews the calculation of fluorescence excited by characteristic radiation in the X-ray microanalyzer and the method for calculating the absorption correction in electron-probe microanalysis. The selection is a valuable reference for readers interested in X-ray technology.

This book was released on 2013-11-11 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication in 1979 of Introduction to Analytical Electron Microscopy (ed. J. J. Hren, J. I. Goldstein, and D. C. Joy; Plenum Press), analytical electron microscopy has continued to evolve and mature both as a topic for fundamental scientific investigation and as a tool for inorganic and organic materials characterization. Significant strides have been made in our understanding of image formation, electron diffraction, and beam/specimen interactions, both in terms of the "physics of the processes" and their practical implementation in modern instruments. It is the intent of the editors and authors of the current text, Principles of Analytical Electron Microscopy, to bring together, in one concise and readily accessible volume, these recent advances in the subject. The text begins with a thorough discussion of fundamentals to lay a foundation for today's state-of-the-art microscopy. All currently important areas in analytical electron microscopy-including electron optics, electron beam/specimen interactions, image formation, x-ray microanalysis, energy-loss spectroscopy, electron diffraction and specimen effects-have been given thorough attention. To increase the utility of the volume to a broader cross section of the scientific community, the book's approach is, in general, more descriptive than mathematical. In some areas, however, mathematical concepts are dealt with in depth, increasing the appeal to those seeking a more rigorous treatment of the subject.

This book was released on 2011-04-14 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scanning electr on microscopy (SEM) and x-ray microanalysis can produce magnified images and in situ chemical information from virtually any type of specimen. The two instruments generally operate in a high vacuum and a very dry environment in order to produce the high energy beam of electrons needed for imaging and analysis. With a few notable exceptions, most specimens destined for study in the SEM are poor conductors and composed of beam sensitive light elements containing variable amounts of water. In the SEM, the imaging system depends on the specimen being sufficiently electrically conductive to ensure that the bulk of the incoming electrons go to ground. The formation of the image depends on collecting the different signals that are scattered as a consequence of the high energy beam interacting with the sample. Backscattered electrons and secondary electrons are generated within the primary beam-sample interactive volume and are the two principal signals used to form images. The backscattered electron coefficient ( ? ) increases with increasing atomic number of the specimen, whereas the secondary electron coefficient ( ? ) is relatively insensitive to atomic number. This fundamental diff- ence in the two signals can have an important effect on the way samples may need to be prepared. The analytical system depends on collecting the x-ray photons that are generated within the sample as a consequence of interaction with the same high energy beam of primary electrons used to produce images.
