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.

Book excerpt: By browsing about 10 000 000 scientific articles of over 200 major journals mainly in a 'cover to cover approach' some 200 000 publications were selected. The extracted data is part of the following fundamental material research fields: crystal structures (S), phase diagrams (also called constitution) (C) and the comprehensive field of intrinsic physical properties (P). This work has been done systematically starting with the literature going back to 1900. The above mentioned research field codes (S, C, P) as well as the chemical systems investigated in each publication were included in the present work. The aim of the Inorganic Substances Bibliography is to provide researchers with a comprehensive compilation of all up to now published scientific publications on inorganic systems in only three handy volumes.
