Pressure has long been recognized as a fundamental thermodynamic variable but its
application was previously limited by the available pressure vessels and probes. The …

Active research is ongoing that investigates the properties of matter under extreme pressure.
Such condensed matter is found inside planets at millions of atmospheres and thousands of …

Pressure profoundly alters all states of matter. The symbiotic development of ultrahigh-
pressure diamond anvil cells, to compress samples to sustainable multi-megabar pressures; …

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 …

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 …

The existing macroscale models of the calcium (alumino) silicate hydrate (C-(A-) SH), the
main binder of concrete, assume that the nanocrystallites maintain random orientation under …

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 …

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 …

Previously measured in situ x-ray diffraction is used to assess the development of internal
elastic strains within grains of a sample of polycrystalline cobalt plastically deformed up to a …

The pressure effects on plastic deformation and phase transformation mechanisms of
materials are of great importance to both Earth science and technological applications …
