Book excerpt: L'interaction des électrons avec la matière cristallisée constitue un domaine de recherches très important en microscopie électronique. L'áccroissement de la tension accélératrice des électrons a permis de développer l'étude de nombreux phénomènes observés tant en microscopie qu'en diffraction électronique. [...] Notre étude porte sur le diamant et l'oxyde de magnesium. Nous utilisons pour nos expériences des cristaux en forme de coin délimité par des faces planes. Dans ce cas, les contours d'extinction correspondent à des franges d'égale épaisseur. L'analyse de la répartition d'intensité dans ces franges permet de déterminer à la fois th et [mu]o. Ce mémoire comprend sept chapitres : Nous rappelons d'abord les résultats d'une première étude de l'absorption des électrons par la matière cristallisée, effectuée pour des tensions comprises entre 50 et 1200 kV. [...] Nous consacrons le second chapitre à l'étude de la distance d'extinction en théorie dynamique à deux faisceaux et à plusieurs faisceaux. [...] Dans le 3e chapitre, nous analysons les phénomènes d'absorption des électrons dans le cas de l'approximation à deux ondes, à l'aide d'une théorie phénoménologique. [...] L'étude de l'interaction des électrons avec des cristaux de diamant pour des tensions accélératrices comprises entre 100 et 1200 kV, fait l'ojet du 4e chapitre. [...]. Nous avons remarqué au cours de nos expériences, que la présence de réflexions intenses, appelées réflexions simultanées, modifie les valeurs de la distance d'extinction et du coefficient moyen d'absorption. C'est la raison pour laquelle nous consacrons une étude particulière à ces réflexions dans le chapitre V. [...] Nous étudions, dans le 6e chapitre, la distance d'extinction et le coefficient moyen d'absorption dans le cas où la condition de Bragg n'est pas vérifiée pour la réflexion considérée. [...] Dans le 7e chapitre, figure l'étude de la variation de la distance d'extinction en fonction de la tension accélératrice pour deux orientations particulères des cristaux d'oxyde de magnésium [...]

Download or read book Adhesion Between Polymers and Concrete Adh sion Entre Polym res Et B ton written by H. R. Sasse and published by Springer. This book was released on 1986 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Download or read book Surface and Interface Chemistry of Clay Minerals written by Robert Schoonheydt and published by Elsevier. This book was released on 2018-11-05 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface and Interface Chemistry of Clay Minerals, Volume 9, delivers a fundamental understanding of the surface and interface chemistry of clay minerals, thus serving as a valuable resource for researchers active in the fields of materials chemistry and sustainable chemistry. Clay minerals, with surfaces ranging from hydrophilic, to hydrophobic, are widely studied and used as adsorbents. Adsorption can occur at the edges and surfaces of clay mineral layers and particles, and in the interlayer region. This diversity in properties and the possibility to tune the surface properties of clay minerals to match the properties of adsorbed molecules is the basis for study. This book requires a fundamental understanding of the surface and interface chemistry of clay minerals, and of the interaction between adsorbate and adsorbent. It is an essential resource for clay scientists, geologists, chemists, physicists, material scientists, researchers, and students. - Presents scientists and engineers with a resource they can rely on for their own research and work involving clay minerals - Includes an in-depth look at ion exchange, adsorption of inorganic and organic molecules, including polymers and proteins, and catalysis occurring at the surfaces of clay minerals - Includes materials chemistry of clay minerals with chiral clay minerals, optical materials and functional films
