A 7 . High Pressure

Recent experiments show evidence of fluctuating magnetism in δ-Pu. This has direct consequences for the atomic volume of this metal phase and gives a simple explanation for its anomalously low density. Earlier there has from the experimental community been a strong emphasis on the absence of magnetism in Pu, a view which has severely delayed the development of a proper description of the physics determining the extraordinary behavior of plutonium. 10:45 A7-2(invited) Title of Talk: Modeling and simulation of clays, carbonates and their interfaces under environmental conditions Authors’ Names: Ali Zaoui Affiliation: Université des Sciences et Technologies de Lille 1, France Abstract: In this talk I will present some recent results related to surface morphology of carbonates, as well as their behaviors under water and pressure effects. The hydrous phases are of considerable interest for their role as precursors to stable carbonate minerals. I will present a detailed recent results concerning structural and energetic stability of dry and hydrous surfaces of calcium In this talk I will present some recent results related to surface morphology of carbonates, as well as their behaviors under water and pressure effects.
