Trace concentration - Huge impact: Nitrate in the calcite/Eu(III) system

Kislon Voitchovsky, Moritz Schmidt

The interactions of trivalent lanthanides and actinides with secondary mineral phases such as calcite is of high importance for the safety assessment of deep geological repositories for high level nuclear waste (HLW). Due to similar ionic radii, calcium-be ...

Local, element-specific and time-resolved dissolution processes on a Mg–Y–RE alloy – Influence of inorganic species and buffering systems

Christian Ludwig, Noémie Elise Ott, Andrea Ulrich

The effect of body fluids inorganic species on element-specific dissolution of a Mg-Y-Rare earth elements (RE) alloy was investigated by flow microcapillary plasma mass spectrometry. A new important aspect of this method is the online monitoring of precipi ...

Speciation-dependent kinetics of uranium(VI) bioreduction

Rizlan Bernier-Latmani, Harish Veeramani

The kinetics of uranium(VI) reduction by Shewanella oneidensis strain MR-1 was studied for varied pH and concentrations of dissolved inorganic carbon (DIC) and calcium. These are key variables affecting U(VI) speciation in aqueous systems. For all conditio ...

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 ...

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

Jan Van Herle, Philippe Buffat, Elena Suvorova Buffat, Sébastien Vaucher, 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, ...
