Viscosity of liquid fayalite up to 9 GPa

Structure of liquid iron at pressures up to 58 GPa.

We report structural data on liquid iron at pressures up to 58 GPa measured by x-ray scattering in a laser heated diamond anvil cell. The determined structure factor preserves essentially the same shape along the melting curve. Our data demonstrate that liquid iron at high pressures is a close-packed hard-sphere liquid. The results place important constraints on the thermodynamic and transport ...

Electrical resistivity of solid and liquid Cu up to 5 GPa: Decrease along the melting boundary

The electrical resistivity of high purity Cu has been investigated by both experiments and first principle calculations at pressures up to 5 GPa and at temperatures in the liquid phase up to 1730 K. The resistivity decreases with P and increases with T and our data are in very good agreement in relation to 1 atm data. Our melting temperature data agree with other experimental studies. We show t...

Molecular response of liquid nitrogen multiply shocked to 40 GPa.

Liquid nitrogen was subjected to multiple shock compression to examine its response to pressures (15-40 GPa) and temperatures (1800-4000 K) previously unexplored in static and shock compression studies. Raman spectroscopy measurements were used to characterize the molecular bond response and to determine temperatures in the peak state. By extending our analysis to include other Raman spectrosco...

Equation of state measurements in liquid deuterium to 70 GPa.

Using intense magnetic pressure, a method was developed to launch flyer plates to velocities in excess of 20 km/s. This technique was used to perform plate-impact, shock wave experiments on cryogenic liquid deuterium ( L-D(2)) to examine its high-pressure equation of state. Using an impedance matching method, Hugoniot measurements were obtained in the pressure range of 30-70 GPa. The results of...
