The major aim of this study is to investigate the OH-defect inventory of orthopyroxene as major host of OH-defects in upper mantle minerals as a function of pressure and bulk composition.
The models start with a bulk composition based on CI chondrites or the composition of SNC meteorites (believed to be Mars crustal fragments excavated by impacts on Mars), a mineralogical model for the composition as a function of pressure and temperature, and then attempt to match planetary mass, radius, and moment of inertia by varying a quasi-adiabatic temperature profile through the planet.
The gas phase composition was analyzed as a function of pressure and plasma power.
We then calculate the modal compositions of minerals for the mantle based on Kimura et al. (20092010), as a function of pressure and temperature.
The extraction capacity of CO2 is a function of pressure, temperature and composition of the crude oil.
Linear burning rates of quasi-homogeneous mixtures of μAl and liquid water as a function of pressure, mixture composition, density and environment gas medium were measured.
The asphaltene precipitation is a function of pressure, temperature, and fluid composition.
A comprehensive driving force for hydrate formation is a function of pressure, temperature, and gas composition; however, its calculation is not as simple as that of subcooling.
The total mass adsorbed is measured with a microbalance as a function of temperature, pressure, and composition of the gas phase.
Both experimental setups allow investigating hydrate kinetics as a function of pressure, temperature, and feed gas composition.
Therefore, it is of great importance to determine "how much" the asphaltenes precipitate as a function of pressure, temperature and liquid phase composition.
