An Internally Consistent Thermodynamic Dataset for Aqueous Species in the System Ca-Mg-Na-K-Al-Si-O-H-C-Cl to 800 °C and 5 Kbar
George D. MironThomas WagnerDmitrii A. KulikBarbara Lothenbach
This study presents an internally consistent thermodynamic dataset for aqueous species in the system Ca-Mg-Na-K-Al-Si-O-H-C-Cl, obtained by adding species of calcium, magnesium and carbon to the core system Na-K-Al-Si-O-H-Cl (Miron...

Steps to Achieving High-Resolution NMR Spectroscopy on Solutions at GPa Pressure
Matthew P. AugustineGerardo OchoaWilliam H. Casey
Recent theoretical advances and molecular-dynamic estimates of the dielectric constant of water have extended the HKF model for aqueous solution chemistry up to 6.0 gigapascals (GPa), which are conditions well...
