High Sodium Solubility in Magnesiowüstite in Iron-Rich Deep Lower Mantle
Marco Cantoni, James Badro, Susannah McGregor Dorfman, Farhang Nabiei
(Mg,Fe)O ferropericlase-magnesiow & uuml;stite has been proposed to host the majority of Earth's sodium, but the mechanism and capacity for incorporating the alkali cation remain unclear. In this work, experiments in the laser-heated diamond anvil cell and ...
Amer Geophysical Union2024Integrating CO2 mineralization in industrial clusters: the benefits of material and heat integration
François Maréchal, Julia Granacher, Rafael Amorim Leandro De Castro Amoedo, Mouhannad Abou Daher
Curbing and capturing CO2 emissions is no longer enough to cope with the demanding environmental challenges of the coming years. Long-term storage technologies need deployment, to help industrial sectors to reach ambitious emission standards. Mineral carbo ...
2023Effect of different ions on dissolution rates of silica and feldspars at high pH
Karen Scrivener, Barbara Lothenbach, Mahsa Bagheri, Mahdieh Shakoorioskooie
The dissolution kinetics of silica-containing minerals in aggregates influences strongly the process of ASR in concrete. In this paper, the effect of different ions on the dissolution rates of SiO2 (amorphous and quartz) and feldspars at high pH values was ...
PERGAMON-ELSEVIER SCIENCE LTD2022Aggregate dissolution in different pore solutions
The occurrence of cracking due to alkali silica reaction (ASR) affects the service life of concrete structures. The dissolution of silica-containing minerals within aggregates causes the formation of ASR products, which fill macroscopic cracks and cause th ...
EPFL2021Role of Iron Sulfide Phases in the Stability of Noncrystalline Tetravalent Uranium in Sediments
Rizlan Bernier-Latmani, Luca Loreggian
Uranium (U) in situ bioremediation has been investigated as a cost-effective strategy to tackle U contamination in the subsurface. While uraninite was believed to be the only product of bioreduction, numerous studies have revealed that noncrystalline U(IV) ...
AMER CHEMICAL SOC2020Active sulfur cycling in the terrestrial deep subsurface
Rizlan Bernier-Latmani, Manon Frutschi, Emma Bell, Chen Qian
The deep terrestrial subsurface remains an environment where there is limited understanding of the extant microbial metabolisms. At Olkiluoto, Finland, a deep geological repository is under construction for the final storage of spent nuclear fuel. It is th ...
2020An alternative model for the formation of hydrous Mg/Ni layer silicates ("deweylite"/"garnierite") in faulted peridotites of New Caledonia: II. Petrography and chemistry of white and green clay infillings
This study, which complements a first mineralogical work, presents detailed petrographic and chemical data on the sequences of clay infillings commonly found in serpentine veins of reactivated faults from the New Caledonian peridotite formation. Chemical t ...
