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 Union2024Investigation of Biogenic Passivating Layers on Corroded Iron
This study evaluates mechanisms of biogenic mineral formation induced by bacterial iron reduction for the stabilization of corroded iron. As an example, the Desulfitobacterium hafniense strain TCE1 was employed to treat corroded coupons presenting urban na ...
2020Dissimilarities in polyphosphate accumulation between Shewanella loihica and the model bacterium Shewanella oneidensis
Polyphosphate plays an important role in the physiological adaptation of bacteria during growth and development, as well as in their response to nutritional and environmental stresses. Moreover, polyphosphate accumulation is of environmental relevance and ...
2019Variations in elastic and electrical properties of crustal rocks with varying degree of microfracturation
Marie Estelle Solange Violay, Lucas Xan Pimienta, Luis Felipe Orellana Espinoza
This work aims at investigating the effect of varying degrees of microfracturing on the joint elastic and electrical transport properties of rocks. Different crustal rocks were subjected to Thermal Treatment, expected to induce microfracturing, up to diffe ...
2019Adsorption of HPDX and CaHPOx (x=1, ...,4) molecules on anatase TiO2 (001) surfaces
perform DFT calculations within the COSMO framework to study the adsorption properties of the CaHPOx (x = 1,...,4) phosphate family, and of the related HPOx acids, on a paradigmatic anatase (001) surface. Of particular interest is CaHPO4, a precursor of hy ...
ELSEVIER SCIENCE BV2019Contaminant loading and competitive access of Pb, Zn and Mn(III) to vacancy sites in biogenic MnO2
Louise Helene Soegaard Jensen, Jasquelin Peña
The scavenging properties of MnO2 are largely attributed to sorption on layer vacancy sites. However, co-occurrence of Mn(II, III) with MnO2 can change mineral reactivity by modifying its Mn(III) content or number of free vacancy sites. These processes are ...
2018Global impact of mineral dust on cloud droplet number concentration
The importance of wind-blown mineral dust for cloud droplet formation is studied by considering (i) the adsorption of water on the surface of insoluble particles, (ii) particle coating by soluble material (atmospheric aging) which augments cloud condensati ...
Copernicus GmbH2017From 2D to 3D Characterization of Materials Subjected to Extreme Pressure and Temperature Conditions
Planetesimal were the first planetary objects to form in the solar system, which later grew to make the proto-planets. Most of these bodies were differentiated as a result of internal heating. Several differentiated bodies have, then, been accreted followi ...
EPFL2017Influence of crustal dust and sea spray supermicron particle concentrations and acidity on inorganic NO3- aerosol during the 2013 Southern Oxidant and Aerosol Study
Satoshi Takahama, Robin Lewis Modini
Inorganic aerosol composition was measured in the southeastern United States, a region that exhibits high aerosol mass loading during the summer, as part of the 2013 Southern Oxidant and Aerosol Study (SOAS) campaign. Measurements using a Monitor for AeRos ...
Copernicus Gesellschaft Mbh2015The incommensurate structure of K3In(PO4)(2)
Gervais Chapuis, Alla Arakcheeva
The incommensurately modulated structure of K3In(PO4)(2) has been solved and refined. The origin of the modulation relates to the ordering of K cations within the hexagonal close packing of the PO4 anions. The driving forces for the modulation of the other ...
