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 …

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 …

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 …

Ammonia is predicted to be one of the major components in the depths of the ice giant
planets Uranus and Neptune. Their dynamics, evolution, and interior structure are …

Under high pressures and temperatures, molecular systems with substantial polarization
charges, such as ammonia and water, are predicted to form superionic phases and dense …

Fluid ammonia is highly associated because of strong intermolecular hydrogen bonding.
This causes different behavior of thermophysical properties from nonpolar fluids, as …

Nondipolar magnetic fields exhibited at Uranus and Neptune may be derived from a unique
geometry of their icy mantle with a thin convective layer on top of a stratified nonconvective …

This work presents an investigation into the premature failure of FeCrAl heating coils after 48
h of continuous exposure to a high-pressure (12 bar) and high-temperature (700° C) …

Motivated by the poor knowledge of the implication of planetary ice on the internal
convection and anomalous magnetic field of ice giants, we perform extensive first-principles …

High pressure–temperature conditions can be readily achieved through the laser-heated
diamond anvil cell (LH-DAC). A stable laser source is required for reliable in situ …
