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 …

A detailed description is presented of the Extreme Conditions Beamline P02. 2 for micro X-
ray diffraction studies of matter at simultaneous high pressure and high/low temperatures at …

Cubic CaSiO3 perovskite is a major phase in subducted oceanic crust, where it forms at a
depth of about 550 kilometres from majoritic garnet,,. However, its rheological properties at …

High-resolution x-ray diffraction and scattering is a key tool for structure analysis not only in
bulk materials but also at surfaces and buried interfaces from the sub-nanometer range to …

Severe plastic deformations (SPD) under high pressure, mostly by high-pressure torsion, are
employed for producing nanostructured materials and stable or metastable high-pressure …

Brillouin spectroscopy is an optical technique that allows one to determine the directional
dependence of acoustic velocities in minerals and materials subject to a wide range of …

The ability to remotely control pressure in diamond anvil cells (DACs) in accurate and
consistent manner at room temperature, as well as at cryogenic and elevated temperatures …

The accurate determination of melting curves for transition metals is an intense topic within
high pressure research, both because of the technical challenges included as well as the …

High pressure phase transformations play an important role in the search for new materials
and material synthesis, as well as in geophysics. However, they are poorly characterized …
