The central theme of this conference, quantitative methods in X-ray spectrometric analy sis, and the large number of papers on that subject attest to the growth of the application and usefulness of X-ray emission. It is a privilege to have as an invited speaker Laverne Birks, one of the original group that put X-ray emission into analytical chemistry. Determination of elements above titanium in the periodic table was considered the province of X-ray fluorescence, and most of the early development was aimed at the analy sis of alloys. The papers in this volume on metals analysis accept most operational features as routine and have concentrated on the improved treatment of the observed data in order to convert them to more accurate results. As the treatment of matrix effects, geometry, and stability have been better understood, corrections have become routine. For most elements that are present in amounts greater than a few parts per million, determinations can now be done with accuracies rivaling wet methods. Trace quantities are being determined to lower and lower amounts, largely owing to improvement of equipment and development of concentration techniques. For most trace elements, X-ray spectrography has become the preferred analytical method. The develop ment of improved methods for separating signals from noise should lead to major reduc tions in minimum detection levels. ····· 1017648448
für 104.63€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The Ninth Annual Conference on Applications of X-Ray Anal ysis sponsored by the University of Denver was held August 10, 11,12, 1960, at the Park Lane Hotel in Denver, Colorado. Forty one papers on new developments in X-ray analytical techniques and instrumentation were presented. This volume contains thirty eight of those papers. Research in X-ray analytical methods is a dynamic and expanding area of scientific investigation. Each year exciting and stimulating progress is reported in the various regions of this field. Suitable documentation of the results is the purpose of the series `Advances in X-Ray Analysis. ` Participation in the Conference by two distinguished European scientists, Dr. Raymond Castaing of the University of Paris, France, and Dr. Arnold Hargreaves of the Manchester College of Science and Technology, England, was made possible through financial aid provided by the United States Office of Naval Re search. This assistance is greatly appreciated. Major contributions to the conference were made by the following individuals who chaired the technical sessions: Dr. William D. Forgeng, Electro Metallurgical Company, Niagara Falls, New York Dr. Kurt F. J. Heinrich, E. I. du Pont de Nemours and Company, Wilmington, Delaware Mr. Robert A.

····· lezzter Preis 105.19€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This accessible text presents a unified approach of treating the microstructure and effective properties of heterogeneous media. Part I deals with the quantitative characterization of the microstructure of heterogeneous via theoretical methods Part II treats a wide variety of effective properties of heterogeneous materials and how they are linked to the microstructure, accomplished by using rigorous methods. The study of random heterogeneous materials is an exciting and rapidly growing multidisciplinary endeavor. This field demands a unified rigorous means of characterizing the microstructures and macroscopic properties of the widely diverse types of heterogeneous materials that abound in nature and synthetic products. This book is the first of its kind to provide such an approach. Emphasis is placed on foundational theoretical methods that can simultaneously yield results of practical utility. The first part of the book deals with the quantitive characterization of the microstructure of heterogeneous materials. The second part of the book treats a wide variety of macroscopic transport, electromagnetic, mechanical, and chemical properties of heterogeneous materials and describes how they are linked to the microstructure of model and real materials. Contemporary topics covered include the statistical mechanics of many-partical systems, the canonical n-point correlation function, percolation theory, computer-simulation methods, image analyses and reconstructions of real materials, homogenization theory, exact property predictions, variational bounds, expansion techniques, and cross property relations. This clear and authoritative volume will be of particular interest to graduate students and researchers in applied mathematics, physics, chemistry, material sciences, engineering, geophysics, and biology. Moreover, the book is self-contained and approachable by nonspecialist. Salvatore Torquato is a professor in the Department of Chemistry and in the Materials Institute at Princeton University. He also holds affiliated appointments at Princeton University in applied and Computational Mathematics Program and in Chemical Engineering. Among other honors, he was a John Simon Guggenheim Fellow in 1998. He has published over two hundred journal articles across a variety of scientific disciplines. ····· 1017674127
