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 Union2024Mapping orthorhombic domains with geometrical phase analysis in rare-earth nickelate heterostructures
Duncan Thomas Lindsay Alexander, Bernat Mundet, Jean-Marc Triscone
Most perovskite oxides belong to the Pbnm space group, composed of an anisotropic unit cell, A-site antipolar displacements, and oxygen octahedral tilts. Mapping the orientation of the orthorhombic unit cell in epitaxial heterostructures that consist of at ...
Melville2024Micromechanics of oxide inclusions in ferrous alloys
Oxide inclusions are inevitably present in steel as a direct consequence of the steelmaking process; as a result, a cubic centimetre of modern steel will generally contain about a million of these hard and brittle micrometre-sized ceramic particles. Inclus ...
EPFL2023New tools for phase segmentation and denoising of analytical STEM data for enhanced chemical sensitivity, applied to Earth mantle research
This thesis is dedicated to developing innovative methodologies that improve elemental quantification in scanning transmission electron microscopy (STEM) using energy-dispersive X-ray spectroscopy (EDXS). The primary motivation stems from a geochemistry pr ...
