Additive Manufacturing of Bioinspired Mineral-Based Composites
Biominerals are used by natural organisms for example as structural supports and optical sensors. They are produced from a limited number of elements and under ambient conditions. Nevertheless, they often possess excellent mechanical properties and sometim ...
EPFL2024Water weakening and the compressive brittle strength of carbonates: Influence of fracture toughness and static friction
Marie Estelle Solange Violay, Barnaby Padraig Fryer, Corentin Jean-Marie Rémi Noël
Water is ubiquitous within the pore space of rocks and has been shown to affect their physical and mechanical behaviour. Indeed, water can act on the rock strength via mechanical (i.e., reducing the effective stresses) or chemical effects (e.g., mineral di ...
2024High 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 Union2024Unraveling the Uptake of Glyoxal on a Diversity of Natural Dusts and Surrogates: Linking Dust Composition to Glyoxal Uptake and Estimation of Atmospheric Lifetimes
The uptake of glyoxal (Gly) on 28 different samples with varying mineralogical origins, such as clays, mineral proxies, and natural dusts from the major arid regions of the Earth, was determined. Experiments were performed at ambient temperature inside a K ...
Amer Chemical Soc2024Controlling crystal cleavage in focused ion beam shaped specimens for surface spectroscopy
Philip Johannes Walter Moll, Matthias Carsten Putzke, Andrew Scott Hunter
Our understanding of quantum materials is commonly based on precise determinations of their electronic spectrum by spectroscopic means, most notably angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy. Both require atomicall ...
Melville2024Electron transfer reactions and their role in soil carbon cycling
Electron transfer reactions are central to the transformation of energy in the environment and play an important role in biogeochemical element cycling. In soils, one of the main drivers of carbon cycling is the activity of organisms that utilize the energ ...
2024Insights from an extensive triaxial testing campaign on a shale for comparative site characterization of a deep geological repository
Lyesse Laloui, Alessio Ferrari, Eleonora Crisci
Several boreholes were drilled for site comparison of a deep geological repository (DGR) in Northern Switzerland. The main target of the exploration program was the >100m thick Opalinus Clay, the designated host rock encountered at approximately 450 to 100 ...
Amsterdam2024Impact of CO2-rich seawater injection on the flow properties of basalts
Lyesse Laloui, Eleni Stavropoulou, Cesare Griner
Permanent CO storage in basalts through mineralisation offers a promising solution for reducing carbon emissions and mitigating climate change. This study focuses on the impact of potential mineralisation on the flow properties of the basaltic material. Fl ...
2024Integrating CO2 mineralization in industrial clusters: the benefits of material and heat integration
François Maréchal, Rafael Amorim Leandro De Castro Amoedo, Julia Granacher, 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 ...
2023Permeability, alteration, and microstructure: A (hopefully) coupled rock physics and geochemical approach to how rock-fluid interactions change permeability
Permeability is a key physical property across all spatial scales in the Earth’s crust and exerts significant control on the behaviour of Earth systems, with implications for natural hazards (e.g., earthquakes, slope instabilities, volcanic eruptions) and ...
