Book Description
The Fifth International Congress on X-Ray Optics and Microanalysis was organized by the Institute of Applied Physics at Tübingen University in Western Germany from September 9th through 14th, 1968. Since 1956, when the First Conference was arranged in Cambridge, England by one of the pioneers in this field, V. E. CossLETT, the experts in the fields of X-Ray Optics and Microanalysis have met every third year to exchange their scientific experiences. Later meetings were held at Uppsala, Sweden in 1959, at Stanford, California in 1962, and at Orsay, Francein 1965. The participants in the 1968 Conference came from the following countries: Germany 140, France 60, Great Britain 55, USA 20, Netherlands 16, Switzerland 12, Austria 9, Sweden 7, Belgium 6, Japan 5, Italy 4, two each from Israel, Yugoslavia, Canada, Norway, Hungary and one each from Argentine, Poland, South Africa. As at the latest congress in Paris the following central topics were treated: General problems of X-ray optics, physical bases of electron beam microanalysis, quantitative problems of X-ray microanalysis, instrumentation, microdiffraction, applications to metal lurgy, mineralogy, and biology. An exhibition showing some of the most modern instruments formed an important part of the conference. The Springer-Verlag, Heidelberg, deserves thanks for the careful and speedy work they have performed in printing these conference proceedings. We are further indebted to all contributors of this volume for their kind cooperation. Tübingen, August 1969 G. MöLLENSTEDT and K. H.

Book Description
The aim of electron probe microanalysis of biological systems is to identify, localize, and quantify elements, mass, and water in cells and tissues. The method is based on the idea that all electrons and photons emerging from an electron beam irradiated specimen contain information on its structure and composition. In particular, energy spectroscopy of X-rays and electrons after interaction of the electron beam with the specimen is used for this purpose. However, the application of this method in biology and medicine has to overcome three specific problems: 1. The principle constituent of most cell samples is water. Since liquid water is not compatible with vacuum conditions in the electron microscope, specimens have to be prepared without disturbing the other components, in parti cular diffusible ions (elements). 2. Electron probe microanaly sis provides physical data on either dry specimens or fully hydrated, frozen specimens. This data usually has to be con verted into quantitative data meaningful to the cell biologist or physiologist. 3. Cells and tissues are not static but dynamic systems. Thus, for example, microanalysis of physiolo gical processes requires sampling techniques which are adapted to address specific biological or medical questions. During recent years, remarkable progress has been made to overcome these problems. Cryopreparation, image analysis, and electron energy loss spectroscopy are key areas which have solved some problems and offer promise for future improvements.

Book Description
The first ICXOM congress held in Cambridge was the brain-child of Dr. Ellis Cosslett, founder of the Electron Optics Section of the Cavendish Laboratory. Dr. Cosslett pioneered research in x-ray optics and microanalysis and retained a close interest in all subject applications for this area of research, including physics, materials science, chemistry, and biology. X-Ray Optics and Microanalysis 1992 was held in his memory. At a special symposium, friends and colleagues reviewed the present status of research in x-ray optics and microanalysis. S.J. Pennycook of Oak Ridge National Laboratory, D.B. Williams of Lehigh University, J.A. Venables et al. of Arizona State University and Sussex University, and C. Jacobsen et al. of SUNY, Stony Brook are among the researchers whose papers are included in this volume.

Book Description
Surface science and colloid science are preeminently experimental subjects. They constitute complementary aspects of a field which has been notably active since World War II; there is every reason to expect that the level of activity will continue to rise in the coming decades, so it is timely to review certain experimental methods of surface and colloid science as they exist, and to evaluate and refine those methods. This volume, and others that will follow, are principally concerned with experimental methods. The working scientist needs access to the latest techniques, of course. He also needs to learn of the potentialities of recently developed techniques which he may not have been aware of. Equally important, or perhaps even more so, he needs to learn of the pitfalls of existing methods. One might say, wistfully, that it would be nice to be able to pick up somebody's description of a new piece of apparatus, to go into the laboratory, to build it, and to have it work, the first time! There is, however, a serious problem of the interaction between the experiment per se and the theory for which the experiment is designed. Very often, this interaction renders problematic the interpretation of "direct" observations. An example, from experience of the senior editor of this volume, is the question of contact angle hysteresis. (See Chapters 1 and 2.

Book Description
* A special volume devoted principally to therole of the late Sir Charles Oatley in the development of the scanning electron microscopeings* It contains historical articles and reminiscences by most of the scientists who have worked on the scanning electron microscope in Oatley's laboratory * Emphasizes broad and in depth article collaborations between world-renowned scientists in the field of image and electron physicsAlthough the scanning electron microscope had a prehistory in Germany and the USA, its real champion was Charles Oatley, who launched his projectin the Cambridge University Engineering Department shortly after the end of World War II. A first microscope was built successfully by D. McMullan, oneof the Guest Editors of this volume and a succession of progressively improved instruments followed. One in particular, built by K.C.A. Smith was commissioned specially for the Canadian Pulp and Paper Research Institute for use in their Montreal laboratories. All these efforts culminated in the commercial model built by the Cambridge Instrument Company and marketed in 1965 under the trade name, Stereoscan.Although this story has been told on several occasions, in particular in these Advances, it seemed appropriate, in the centenary year of the birth of Sir Charles Oatley, that more details should be published to celebrate these achievements. This volume is the result. It contains not only historical articles and reminiscences by most of the scientists who have worked on the scanning electron microscope in Oatley's laboratory but also full or partial reproductions of many of the key publications, beginning with McMullan's early paper of 1953 and including Oatley's own "Early history of the scanning electron microscope" (1982). A website has been created, in which supplementary material is collected.This volume is a tribute to a bold pioneering scientist and a vivid record of the creation of the first commercial scanning electron microscopes and of subsequent developments. * A special volume devoted principally to therole of the late Sir Charles Oatley in the development of the scanning electron microscopeings* It contains historical articles and reminiscences by most of the scientists who have worked on the scanning electron microscope in Oatley's laboratory* Emphasizes broad and in depth article collaborations between world-renowned scientists in the field of image and electron physics

Book Description
This supplement of Mikrochimica Acta contains selected papers from the Second Workshop of the European Microbeam Analysis Society (EMAS) "Modern Developments and Applications in Microbeam Analysis", on which took place in May 1991 in Dubrovnik (Yugoslavia). EMAS was founded in 1987 by members from almost all European countries, in order to stimulate research, applications and development of all forms of microbeam methods. One of the most important activities EMAS is the organisation of biannual workshops for demonstrating the current status and developing trends of microbeam methods. For this meeting, EMAS chose to highlight the following topics: electron-beam microanalysis (EPMA) of thin films and quantitative analysis of ultra-light elements, Auger electron spectroscopy (AES), electron energy loss spec trometry (EELS), high-resolution transmission electron microscopy (HRTEM), quantitative analysis of biological samples and standard-less electron-beam microanalysis. Seven introductory lectures and almost seventy poster presentations were given by speakers from twelve European and two non-European (U.S.A. and Argentina) countries were made. One cannot assume that all fields of research in Europe were duly represented, but a definite trend is discernible. EPMA with wavelength-dispersive spectrometry (WDS) or energy-dispersive spectrometry (EDS) is the method with by far the widest range of applications, followed by TEM with EELS and then AES. There are also interesting suggestions for the further development of new appa ratus with new fields of application. Applications are heavily biased towards materials science (thin films in microelectronics and semicon ductors), ceramics and metallurgy, followed by analysis of biological and mineral samples.

Book Description
In 1968, the National Bureau of Standards (NBS) published Special Publication 298 "Quantitative Electron Probe Microanalysis," which contained proceedings of a seminar held on the subject at NBS in the summer of 1967. This publication received wide interest that continued through the years far beyond expectations. The present volume, also the result of a gathering of international experts, in 1988, at NBS (now the National Institute of Standards and Technology, NIST), is intended to fulfill the same purpose. After years of substantial agreement on the procedures of analysis and data evaluation, several sharply differentiated approaches have developed. These are described in this publi cation with all the details required for practical application. Neither the editors nor NIST wish to endorse any single approach. Rather, we hope that their exposition will stimulate the dialogue which is a prerequisite for technical progress. Additionally, it is expected that those active in research in electron probe microanalysis will appreciate more clearly the areas in which further investigations are warranted.
