This review paper focuses on dislocations and plastic deformation in magnesium oxide
crystals. MgO is an archetype ionic ceramic with refractory properties which is of interest in …

Seismic anisotropy has been found in many regions of the Earth's interior. Its presence in the
Earth's crust has been known since the 19th century, and is due in part to the alignment of …

Subduction of oceanic lithosphere is the main process by which material from Earth's
surface and atmosphere is recycled back into the deep mantle. Seismic images indicate that …

Plastic deformation of olivine at relatively low temperatures (ie, low‐temperature plasticity)
likely controls the strength of the lithospheric mantle in a variety of geodynamic contexts …

Plate tectonics, which shapes the surface of Earth, is the result of solid-state convection in
Earth's mantle over billions of years. Simply driven by buoyancy forces, mantle convection is …

Observations of seismic anisotropy just above the core‐mantle boundary are a powerful way
to understand the dynamics of the lowermost mantle. Here we present models of seismic …

Gradient nanostructured metallic materials with a gradual change of grain boundary and
dislocation density display unprecedent mechanical properties. Herein, we uncover a …

Following the discovery of high-entropy alloys, high-entropy oxides have gained
considerable interest due to their unconventional structural characteristics and versatile …

A first-principles computational scheme was applied for studying edge and screw
dislocations in non-elemental systems for the first time. For the case of TiN as a model …

Abstract Bridgmanite (Mg, Fe) SiO 3 and ferropericlase (Mg, Fe) O are the most abundant
phases in the lower mantle and localized regions of the D ″layer just above the core mantle …
