Over the past few decades, hydrous minerals were thought to be absent in the lower mantle,
due to their instability at high-pressure conditions. Recently, however, hydrous phases …

Geophysical remote-sensing methods, particularly seismology, provide an incredibly
detailed view of the structure and composition of Earth's mantle. The seismic velocity …

We have studied the H 2 O ice VII–ice X phase transition at room temperature by performing
three quasicontinuous synchrotron time-resolved x-ray-diffraction experiments in a dynamic …

Three-dimensional finite element (FE) modelling, with representation of materials at grain
scale in realistic sample volumes, is capable of accurately describing elastic wave …

Abstract Knowledge of the elasticity of high‐pressure ice is key to constructing the internal
structure of various planetary bodies. Here, we present direct experimental constraints on …

The externally-heated diamond anvil cell (EHDAC) can be used to generate simultaneously
high-pressure and high-temperature conditions found in Earth's and planetary interiors …

Using a density functional theory based approach, we explore the symmetrization and
proton dynamics in ice-VII, for which recent high-pressure NMR experiments indicate …

We investigate the effect of nuclear quantum effects (NQEs) of hydrogen atoms on the
elasticity of ice VII at high pressure and ambient-temperature conditions using ab initio path …

The melting curve of H2O was investigated up to 54 GPa and∼ 2000 K by Brillouin
scattering spectroscopy in a diamond anvil cell. A CO2 laser was used for heating the H2O …

Externally heated diamond anvil cells provide a stable and uniform thermal environment,
making them a versatile device to simultaneously generate high-pressure and high …
