Comparative dissolution kinetics of biogenic and chemogenic uraninite under oxidizing conditions in the presence of carbonate

Rizlan Bernier-Latmani, Harish Veeramani, Jonathan Sharp

The long-term stability of biogenic uraninite with respect to oxidative dissolution is pivotal to the success of in situ bioreduction strategies for the subsurface remediation of uranium legacies. Batch and flow-through dissolution experiments were conduct ...

Pd-Supported Catalysts: Evolution of Support Porous Texture along Pd Deposition and Alkali-Metal Doping

Adsorption of N-2 at 77 K and scanning electron microscopy have been used to measure the changes in the support morphology, at nano- and microscale level, along the processes involved in the preparation of a supported Pd catalyst: Pd deposition, doping, an ...

The role of calcium and magnesium in the concrete tubes of the sandcastle worm

Georg Fantner

Sandcastle worms Phragmatopoma californica build mound-like reefs by sticking together large numbers of sand grains with cement secreted from the building organ. The cement consists of protein plus substantial amounts of calcium and magnesium, which are no ...

Characterization of perovskite powders for cathode and oxygen membranes made by different synthesis routes

Jan Van Herle, Philippe Buffat, Sébastien Vaucher, Elena Suvorova Buffat, Nicolas Xanthopoulos

Strontium lanthanum manganite (LSM) and lanthanum ferrite (LSF) perovskite cathode and oxygen membrane materials were synthesized using different techniques: spray pyrolysis, a modified citrate route, oxalate and carbonate co-precipitations. The use of Ca, ...

Distribution of magnesium in coral skeleton

Anders Meibom

Ion micro-probe imaging of the aragonite skeleton of Pavona clavus, a massive reef-building coral, shows that magnesium and strontium are distributed very differently. In contrast to strontium, the distribution of magnesium is strongly correlated with the ...

Nanobacteria-like calcite single crystals at the surface of the Tataouine meteorite

Philippe Gillet

Nanobacteria-like objects evidenced at the surface of the orthopy-roxenes of the Tataouine meteorite in South Tunisia have been studied by scanning and transmission electron microscopies. A method of micromanipulation has been developed to ensure that exac ...

Effect of magnesium on the properties of LiNbO3 thin films prepared from polymeric precursors

Nava Setter

The effect of magnesium addition on the phase formation, microstructure and electric and ferroelectric properties of LiNbO3 thin films prepared through polymeric precursors was analyzed. By X ray diffraction no secondary phase was observed with the increas ...
