Available in PDF, EPUB and Kindle. Book excerpt: Ce travail est une contribution à l'étude du système Cs-U-O. Il met en évidence la modification du degré d'oxydation de l'uranium, induite par le césium, par l'intermédiaire des anions oxygène. Ceci a été montré de deux manières différentes: la première concerne d'abord la détermination des structures cristallines de plusieurs uranates de césium, réalisée à partir des données obtenues par diffraction des rayons X et des neutrons, à l'aide de la méthode de Rietveld. Elle a été complétée par des examens faits, d'une part par spectroscopie de photoélectrons X (XPS) afin de préciser le ou les degrés d'oxydation des cations uranium, d'autre part par spectroscopie d'absorption des rayons X (XAS) pour étudier directement leur environnement local. La méthode des valences électrostatiques a permis de corroborer les divers résultats. La seconde porte sur des couches minces simulant les joints de grains du combustible nucléaire irradié. Le décapage réactif d'uranium métallique par des ions argon, en présence d'oxygène en quantité connue, a, tout d'abord permis de préparer des couches de dioxyde UO2. Celles-ci ont ensuite été recouvertes par du césium, le degré d'oxydation de l'uranium étant simultanément suivi par spectroscopie de photoélectrons UV (UPS) et X (XPS). Un décapage réactif d'uranium en présence d'oxygène et de vapeur de césium, a enfin conduit à la formation de couches mixtes de ces trois éléments chimiques, qui ont été étudiés comme précédemment. Lors de la formation de couches mixtes constituées d'uranium, césium et oxygène, la formation de cation U6+ a pu être montrée, alors que dans les même conditions, ils n'apparaissent pas en l'absence de césium.

Available in PDF, EPUB and Kindle. Book excerpt: Clays and soils are of great importance in various scientific fields, such as agriculture and environmental science, and in mineral deposits. Students and close collaborators of Georges Millot, the eminent French clay sedimentologist, have put together a book with topics ranging from weathering processes and diagenetic evalution of sediments to sedimentary mineral deposits. The book is of interest to practitioners, advanced students as well as teachers in the above fields.

Book excerpt: This book explores important chapters of past and recent African history from a multidisciplinary perspective. It covers an extensive time range from the evolution of early humans to the complex cultural and genetic diversity of modern-day populations in Africa. Through a comprehensive list of chapters, the book focuses on different time-periods, geographic regions and cultural and biological aspects of human diversity across the continent. Each chapter summarises current knowledge with perspectives from a varied set of international researchers from diverse areas of expertise. The book provides a valuable resource for scholars interested in evolutionary history and human diversity in Africa.

Download or read book Principles of Polarography written by Jaroslav Heyrovský and published by Elsevier. This book was released on 2013-09-11 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles of Polarography is a revised and extended version of an original Czech edition that appeared in 1962 at the Publishing House of the Czechoslovak Academy of Sciences in Prague. Based on a one-term course of lectures for third-year students of chemistry at the Charles University it brings the fundamental results of more than forty years' research in the field of polarography. The book contains 22 chapters and opens with a discussion of the principles of polarography. This is followed by separate chapters on polarizable electrodes used in polarography; charging current; influence of the resistance of the electrolyte on polarographic curves; migration and diffusion-controlled currents; and equation of a reversible polarographic wave. Subsequent chapters deal with reversible processes controlled by diffusion of complex ions; reversible reduction of organic substances; deposition of mercury ions; irreversible electrode processes; applications of limiting currents; polarographic curves for the formation of semiquinones and dimers; and catalytic hydrogen currents.
