In stark contrast to common ice, I h, water ice at planetary interior conditions has been
predicted to become superionic with fast-diffusing (that is, liquid-like) hydrogen ions moving …

In the phase diagram of water, superionic ices with highly mobile protons within the stable
oxygen sublattice have been predicted at high pressures. However, the existence of …

Laser-heated diamond anvil cell (LH-DAC) experimentation has emerged as a leading
technique for materials processing at extreme pressures and temperatures. LH-DAC …

Supercritical water is fundamental in many fields of applications and a precise
characterization of the supercritical state is of uttermost importance for this liquid. In a fluid …

Structural transformation of hot dense water ice is investigated by combining synchrotron x-
ray diffraction and a laser-heating diamond anvil cell above 25 GPa. A transition from the …

This Review presents the state of knowledge of the thermophysical properties of water in all
its phases and the reference formulations that provide standardized, recommended values …

The phase diagram and melting curve of water ice is investigated up to 45 GPa and 1600 K
by synchrotron x-ray diffraction in the resistively and laser heated diamond anvil cell. Our …

From first-principles molecular dynamics, we investigate the relation between the superionic
proton conduction and the behavior of the O─ H⋯ O bond (ice VII′ to ice X transition) in …

All the different phases of water ice between 2 GPa and several megabars are based on a
single body-centered cubic sub-lattice of oxygen atoms. They differ only by the behavior of …

The field of high-pressure materials research has grown steadily over the last seven
decades, with many remarkable discoveries having been made. This work is part II of a three …
