Recent progress in theoretical mineral physics based on the ab initio quantum mechanical computation method has been dramatic in conjunction with the advancement of computer technologies. It is now possible to predict stability and several physical properties of complex minerals quantitatively not only at high pressures but also at high temperatures with uncertainties that are comparable to or even smaller than those attached in experimental data. Our present challenges include calculations of high-P,T elasticity to constrain the lower mantle mineralogy, transport properties such as lattice thermal conductivity, and further extensions to terapascal phase equilibria of Earth materials for studying planetary interiors. [ab initio density functional computation method, high-P,T phase relation, thermodynamics, elasticity, lattice thermal conductivity]

We present a review of the superconducting properties of Cu, Sr and Nb doped Bi2Se3 compounds with a focus on high pressure effects. The parent compound Bi2Se3 is a topological insulator at ambient pressure and exhibits pressure-induced crystallographic phase transitions and superconductivity above 10 GPa. The doped compounds are all bulk superconductors with Tc~3 K and have been investigated intensively in the past decade because of their candidature for topological superconductivity (TSC). A key role as regards topological superconductivity is played by spontaneous rotational symmetry breaking (RSB), which is observed, for instance, as an anisotropy in the upper critical field Bc2. We discuss the pressure variation of Tc and the concomitant effect on the upper critical field. An analysis of the basal-plane anisotropy of Bc2 is presented in the context of an oddparity unconventional superconducting state. [topological superconductor, rotational symmetry breaking, resistivity, upper critical field, critical pressure]

Research and development of CO2 capture technologies are of great importance in the context of global warming mitigation. Among those, amines are the most widely used compounds to remove CO2 from a gas stream. In this article, amine-based CO2 capture methods are briefly reviewed with a particular focus on amine-CO2 chemistry, CO2 solubility in amine solvent, and its pressure dependence. It is also described how the molecular structure of amine affects the CO2 absorption-desorption performance by comparing several amines. [absorption, amine, bicarbonate, carbamate, chemical reaction, gas-liquid equilibrium, gas separation]
