Available in PDF, EPUB and Kindle. Book excerpt: During the past several years some very important advances in electron microscopy have been made in instrument design and performance as well as in specimen preparation techniques. The resulting improvement in resolution has opened up a new pattern of study, with greater emphasis now being placed on fine structural details which were not able to be resolved in earlier studies. With some of the new microscopes a resolving power as low as 8 Å can be obtained in direct observations of the specimen, while the lowest possible resolution with a replica technique is about 20 to 30 Å. The latter appears to be limited chiefly by the structure of the shadowing metals. With the development of a new replica technique made possible with Bradley's method of forming evaporated carbon films (1), particular attention is being paid to fine structure in clay minerals, glasses, and other ceramic materials. The examination of bulk clays has revealed details that are important in attempting to define the natural state of the mineral and has helped to provide logical explanations for some of the physical and chemical properties of importance when they are used as catalysts and in the manufacture of certain products in which clays play an important part. Surface details on glasses show fracture paths, liquid immiscibility, location and size of ucleating agents, weathering effects, and the effects of chemical surface treatments. In the study of ceramic bodies, electron micrographs of fractured specimens show how surface topography is related to particle size of the raw clay, the presence of impurities, and the firing temperature. This information has been helpful in basic studies of the formation of high-temperature phases in fired clays and has provided information on structural development which may be correlated with properties of the test specimens. Replica studies of other minerals have also been carried out, including studies of structure in crystals grown from solutions containing added impurities. Direct examinations of clays and other minerals are made for the determination of particle size distributions, the determination of the morphology of individual particles, or the determination of the state of aggregation of a specimen. The preparation of specimens for direct examination usually takes less time than that required for replica studies and under normal conditions permits the use of the ultimate resolving power of the instrument. By a simple selection of proper lenses, the electron microscope can now be converted readily for electron diffraction studies using an aperture system which permits one to "select" diffraction patterns from areas of over 30? down to less than 2? in diameter. One of its important uses is in the identification of small quantities of impurities in samples which by X-ray diffraction may appear to be "pure." It is used also in the study of single crystals to obtain information on unit-cell parameters of compounds whose crystal size is so small as to preclude single crystal X-ray analysis.

This book was released on 2011-07-14 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thirty papers in this 1986 volume review the scientific knowledge of the nature of flint and chert at this time. These papers were presented at a 1983 interdisciplinary and international conference on flint and other cherts. Each contribution has been meticulously assessed and edited prior to publication. This collection is principally concerned with the geology and geochemistry of flint in European chert. Topics include the origin of flint; scanning electron microscopy of surface textures; and the behaviour of flint under periglacial conditions. There is a companion volume, edited by G. de G. Sieveking and M. B. Hart, on the archaeological uses of flint.

This book was released on 2006-04-11 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books are available that detail the basic principles of the different methods of surface characterization. On the other hand, the scientific literature provides a resource of how individual pieces of research are conducted by particular labo- tories. Between these two extremes the literature is thin but it is here that the present volume comfortably sits. Both the newcomer and the more mature scientist will find in these chapters a wealth of detail as well as advice and general guidance of the principal phenomena relevant to the study of real samples. In the analysis of samples, practical analysts have fairly simple models of how everything works. Superimposed on this ideal world is an understanding of how the parameters of the measurement method, the instrumentation, and the char- teristics of the sample distort this ideal world into something less precise, less controlled, and less understood. The guidance given in these chapters allows the scientist to understand how to obtain the most precise and understood measu- ments that are currently possible and, where there are inevitable problems, to have clear guidance as the extent of the problem and its likely behavior.

Download or read book Gigaseal Formation in Patch Clamping written by Majid Malboubi and published by Springer Science & Business Media. This book was released on 2013-07-24 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an investigation of gigaseal formation using micro/nanotechnology. The aims of the book are twofold. First, it explains the mechanisms of gigaseal formation using the latest discoveries. Second, it provides practical techniques for frequent formation of high resistance seals. The formation of a high-resistance electrical seal, also known as a gigaseal, between a cell membrane and a glass micropipette tip is essential in patch-clamp experiments. Even though four decades have passed since the introduction of the patch-clamping technique by Neher and Sakmann, gigaseal formation remains an obstacle in developing the high-throughput ion channel screening systems required by the pharmaceutical industry. Here the authors share their latest methods for achieving gigaseal formation and describe techniques that are highly desirable at both research and industrial levels. Nanotechnology has been found to be a powerful tool for studying and modifying glass micropipettes and in tackling the problem of gigaseal formation.
