Download or read book Light and Electron Microscopy written by Elizabeth M. Slayter and published by Cambridge University Press. This book was released on 1992-10-30 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The compound optical microscope, in its various modern forms, is probably the most familiar of all laboratory instruments and the electron microscope, once an exotic rarity, has now become a standard tool in biological and materials research. Both instruments are often used effectively with little knowledge of the relevant theory, or even of how a particular type of microscope functions. Eventually however, proper use, interpretation of images and choices of specific applications demand an understanding of fundamental principles. This book describes the principles of operation of each type of microscope currently available and of use to biomedical and materials scientists. It explains the mechanisms of image formation, contrast and its enhancement, accounts for ultimate limits on the size of observable details (resolving power and resolution) and finally provides an account of Fourier optical theory. Principles behind the photographic methods used in microscopy are also described and there is some discussion of image processing methods. The book will appeal to graduate students and researchers in the biomedical sciences, and it will be helpful to students taking a course involving the principles of microscopy.

Available in PDF, EPUB and Kindle. Book excerpt: Research in Chemical Kinetics, Volume 1 focuses on authoritative review articles on a wide range of developing topics in the kinetics of gaseous and condensed phases. The selection first elaborates on gas-phase kinetics of free radicals studied by pulse radiolysis combined with time-resolved infrared diode laser spectroscopy and solid/liquid reactions of environmental significance. Discussions focus on coprecipitation of phosphate with calcite, reactions of silica and quartz, infrared spectroscopy of free radicals, and kinetics of methyl radicals. The book then examines the collision energy dependence of reaction cross sections and photoelectrochemical dynamics, including organometallic photoelectrochemistry and photofragmentation voltammetry, contrasting reactivity of ion radical excited states, photoelectrochemical reaction mechanisms, and experimental methods. The publication tackles collisional electronic energy transfer in CN free radicals, photo-ion imaging techniques and future directions in reactive scattering, and photoelectrochemical dynamics. Topics include photoelectrochemical reaction mechanisms, photoelectrochemical measurement of quantum yields, photofragment translational spectroscopy, and velocity distributions. The selection is a valuable reference for researchers interested in the kinetics of gaseous and condensed phases.
Download or read book Advances in Molecular Structure Research written by and published by Elsevier. This book was released on 1995-09-28 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in molecular structure research reflects progress in chemistry in many ways. Much of it is thus blended inseparably with the rest of chemistry. It appears to be prudent, however, to review the frontiers of this field from time to time. This may help the structural chemist to delineate the main thrusts of advances in this area of research. What is even more important though, these efforts may assist the rest of the chemists to learn about new possibilities in structural studies, both methodological and interpretation. The aim is to make this a user-oriented series. Structural chemists of excellence will be critically evaluating a field or direction including their own achievements, and charting expected developments.
Download or read book The Flavonoids written by Jeffrey B. Harborne and published by Springer. This book was released on 2013-11-11 with total page 1218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flavonoids, one of the most numerous and widespread groups of natural constituents, are important to man not only because they contribute to plant colour but also because many members (e.g. coumestrol, phloridzin, rotenone) are physiologically active. Nearly two thousand substances have been described and as a group they are universally distributed among vascular plants. Although the anthocyanins have an undisputed function as plant pigments, the raison d'etre for the more widely distributed colourless flavones and flavonols still remains a mystery. It is perhaps the challenge of discovering these yet undisc10sed functions which has caused the considerable resurgence of interest in flavonoids during the last decade. This book attempts to summarize progress that has been made in the study of these constituents since the first comprehensive monograph on the chemistry of the flavonoid compounds was published, under the editorship of T. A. Geissman, in 1962. The present volume is divided into three parts. The first section (Chapters 1-4) deals with advances in chemistry, the main emphasis being on spectral techniques to take into account the re cent successful applications of NMR and mass spectral measurements to structural identifications. Recent developments in isolation techniques and in synthesis are also covered in this section. Advances in chemical knowledge of individual c1asses of flavonoid are mentioned inter aha in later chapters of the book.

Download or read book Catalysis written by John R. Anderson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of a commercially successful process for the catalytic synthesis of ammonia was a scientific as well as a technical triumph. Its implications were con siderable. It demonstrated the power of a combination of innovative technology and engineering together with basic chemical science, and it introduced ideas and techniques into catalytic science and process engineering which are still with us today. In a real sense, this process changed the face of industrial chemistry and process technology. Of course, the key step in the direct synthesis of ammonia was the development of an efficient catalyst, and the historical account given by Dr. S. A. Topham in the first chapter of this volume shows how this was success fully accomplished, and how this was combined with the successful solution of other daunting technical problems to make the overall process possible. The microstructure of a catalyst is an important feature which determines its behaviour, and the electron microscope is one of the most important instrumental methods by means of which structural and microstruc tural information can be obtained. Nevertheless, the elec tron-optical processes of image formation are complex, but need to be properly understood if image interpreta tion is to be done reliably. In the second chapter of this volume, Dr. J. V. Sanders addresses the entire field of the application of electron microscopic methods to the examination of catalysts.

Download or read book The Neglect of Experiment written by Allan Franklin and published by Cambridge University Press. This book was released on 1989-09-29 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: What role have experiments played, and should they play, in physics? How does one come to believe rationally in experimental results? The Neglect of Experiment attempts to provide answers to both of these questions. Professor Franklin's approach combines the detailed study of four episodes in the history of twentieth century physics with an examination of some of the philosophical issues involved. The episodes are the discovery of parity nonconservation ( or the violation of mirror symmetry) in the 1950s; the nondiscovery of parity nonconservation in the 1930s, when the results of experiments indicated, at least in retrospect, the symmetry violation, but the significance of those results was not realized; the discovery and acceptance of CP ( combined parity-charge conjugations, paricle-antiparticle) symmetry; and Millikan's oil-drop experiment. Franklin examines the various roles that experiment plays, including its role in deciding between competing theories, confirming theories, and calling fo new theories. The author argues that one can provide a philosophical justification for these roles. He contends that if experiment plays such important roles, then one must have good reason to believe in experimental results. He then deals with deveral problems concerning such reslults, including the epistemology of experiment, how one comes to believe rationally in experimental results, the question of the influence of theoretical presuppositions on results, and the problem of scientific fruad. This original and important contribution to the study of the philosophy of experimental science is an outgrowth of many years of research. Franklin brings to this work more than a decade of experience as an experimental high-energy physicist, along with his significant contributions to the history and philosophy of science.
