Unconventional resistivity at the border of metallic antiferromagnetism in NiS2 [PDF]

, 2006
We report low-temperature and high-pressure measurements of the electrical resistivity \rho(T) of the antiferromagnetic compound NiS_2 in its high-pressure metallic state. The form of \rho(T) suggests that metallic antiferromagnetism in NiS_2 is quenched

Thermodynamic Properties of MgAl₂O₄ Spinel at High Temperatures and High Pressures

Crystals, 2023
Thermodynamic properties of MgAl2O4 spinel are significant in understanding the phase relations of the Earth’s crust and upper mantle, but available values from experimental measurements are limited at ambient pressure conditions to date.

High Pressure and Road to Room Temperature Superconductivity

, 2018
High pressure serves as a path finding tool towards novel structures, including those with very high Tc.The superconductivity in sulfur hydrides with record value (203 K) is caused by the phonon mechanism.

Effects of Al Content on the Corrosion Behaviors of Low Cr Bearing Steels in NaCl Solutions

International Journal of Electrochemical Science, 2021
The effects of Al content on the corrosion behaviors of aluminum-bearing steels were studied in NaCl solutions. Electrochemical measurements and Raman and scanning electron microscopy (SEM) surface analyses revealed that the aluminum-bearing steel formed

Pressure effects on the superconducting thin film Ba$_{1-x}$K$_{x}$Fe$_{2}$As$_{2}$

, 2012
We report electrical resistivity measurements on a high-quality Ba$_{1-x}$K$_{x}$Fe$_{2}$As$_{2}$ thin film ($x=0.4$) under pressure. The superconducting transition temperature (=39.95 K) of the optimally-doped thin film shows a dome shape with pressure,

Effect of Thermoelastic Properties of the Pyrope-Almandine Solid Solutions on the Entrapment Pressure of Garnet-Related Elastic Geobarometer

Frontiers in Earth Science, 2022
The pyrope (Prp)–almandine (Alm) solid solutions are the most fundamental garnet components on the Earth, and both the quartz inclusions in garnet (QuiG) barometry and the garnet inclusions in diamond barometry need to be constrained by the thermoelastic

High-pressure and high-temperature differential scanning calorimeter for combined pressure-concentration-temperature measurements of hydrides [PDF]

Review of Scientific Instruments, 2009
The design and construction of a high-pressure (200 bar) and high-temperature (600 °C) heat-flow differential scanning calorimeter (DSC) for the in situ investigation of the hydrogenation and dehydrogenation reactions of hydrides is presented. In combination with a pressure-concentration-temperature (pcT) system, simultaneous thermodynamic and ...
