Over the past six years (2015±2021), many superconducting hydrides with critical
temperatures Tc up to+ 15 C, which are currently record high, have been discovered. Now …

In the past couple of decades, the laser-heated diamond anvil cell (combined with in situ
techniques) has become an extensively used tool for studying pressure-temperature …

We present a new design of a universal diamond anvil cell, suitable for different kinds of
experimental studies under high pressures. Main features of the cell are an ultimate 90 …

Although chemically very simple, Fe2O3 is known to undergo a series of enigmatic
structural, electronic and magnetic transformations at high pressures and high temperatures …

Since the early days of X-ray diffraction, researchers have tried to follow the evolution of
crystal structures under extremes of pressure. Recently, interest in this area has exploded …

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 …

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 …

Among complex oxides, perovskite-based manganites play a special role in science and
technology.[1, 2] They demonstrate colossal magnetoresistance,[3] and can be employed as …

Carbon-bearing solids, fluids, and melts in the Earth's deep interior may play an important
role in the long-term carbon cycle. Here we apply synchrotron X-ray single crystal micro …

Three single-crystals of magnesium silicate perovskite with differing chemical compositions
have been studied by means of synchrotron X-ray diffraction in diamond anvil cells with He …
