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.

Earth Pressure During Earthquake
Soils and Foundations, 1973 ABSTRACT In order to estimate the active earth pressure and the earth pressure at rest against the walls during earthquake, the authors carried out the tests using a large scale vibrating soil bin in laboratory. The resultant force due to the oscillating earth pressure, its applied point and the angle of wall friction were measured during the wall ...

The effect of temperature evolution on the interior structure of H${}_{2}$O-rich planets [PDF]
, 1996 For most planets in the range of radii from 1 to 4 R$_{\oplus}$, water is a major component of the interior composition. At high pressure H${}_{2}$O can be solid, but for larger planets, like Neptune, the temperature can be too high for this.

The Pressure and Temperature Limits of Likely Rocky Exoplanets
, 2019 The interior composition of exoplanets is not observable, limiting our direct knowledge of their structure, composition, and dynamics. Recently described observational trends suggest that rocky exoplanets, that is, planets without significant volatile ...

Deep carbon cycle constrained by carbonate solubility
Nature Communications, 2021 Carbonate mineral aqueous solubility decreases as carbonates become more Mg-rich during subduction. Coupled with regional variations in amounts of carbon and water subducted, this explains discrepancies in estimates of carbon recycling, suggesting that ...

Local structure of REFeAsO (RE=La, Pr, Nd, Sm) oxypnictides studied by Fe K-edge EXAFS
, 2009 Local structure of REOFeAs (RE=La, Pr, Nd, Sm) system has been studied as a function of chemical pressure varied due to different rare-earth size. Fe K-edge extended X-ray absorption fine structure (EXAFS) measurements in the fluorescence mode has ...

Possible re-entrant superconductivity in EuFe2As2 under pressure [PDF]
, 2008 We studied the temperature-pressure phase diagram of EuFe2As2 by measurements of the electrical resistivity. The antiferromagnetic spin-density-wave transition at T_0 associated with the FeAs-layers is continuously suppressed with increasing pressure ...

Surface atmospheric pressure excitation of the translational mode of the inner core
, 2014 Using hourly atmospheric surface pressure field from ECMWF (European Centre for Medium-Range Weather Forecasts) and from NCEP (National Centers for Environmental Prediction) Climate Forecast System Reanalysis (CFSR) models, we show that atmospheric ...
