Hydrogen-based superconductors provide a route to the long-sought goal of room-
temperature superconductivity, but the high pressures required to metallize these materials …

Solids in nature can be generally classified into crystalline and non-crystalline states,,,,,–,
depending on whether long-range lattice periodicity is present in the material. The …

The theoretical predictions and experimental syntheses of hydrogen sulfide (H 3 S) have
ignited a surge of research interest in hydride superconductors. Over the past two decades …

Under extreme conditions of high pressure and temperature, liquids can undergo substantial
structural transformations as their atoms rearrange to minimise energy within a more …

The goal of this paper is to simplify and reduce the cost of manufacturing tungsten carbide.
The work presents the results of experimental studies that prove the possibility of …

Penetrating, high-energy synchrotron X-rays are in strong demand, particularly for high-
pressure research in physics, chemistry and geosciences, and for materials engineering …

A substantial amount of subducted basaltic crusts may exist in the lower mantle. It features
distinct chemical composition from the peridotitic mantle and plays important roles in the …

Water transported by subducted oceanic plates changes mineral and rock properties at high
pressures and temperatures, affecting the dynamics and evolution of the Earth's interior …

Mantle convection manifests in the subduction of cold slabs and the upwelling of hot plumes,
driving both near-surface processes such as volcanism and seismicity and the chemical …

Stishovite, a rutile-structured polymorph of SiO2, is a main component of subducted basaltic
lithologies in the lower mantle. At mid lower-mantle depths, a second-order ferroelastic …
