Developing an elevated temperature Pourbaix diagram for zirconium and multi-element Pourbaix diagram of Zircaloy-4
… This lack of information is addressed through solubility measurements and the development of elevated temperature Pourbaix (E-pH) diagrams for zirconium and Zircaloy-4. These Pourbaix diagrams of zirconium and multi-element diagram (Sn, Zr, Cr) of Zircaloy-4 were developed at 373.15K (100 °C). …

Deuterium Phase Behavior in Thin Film Pd
… in situ neutron reflectometry. Room temperature solubility isothermal curves, out-of-plane film expansion, and deuterium depth profiles were determined from fits to the neutron reflectivity data. The measurements demonstrate that the deuterium solubility behavior, both in solid solution and …

Type 3 porous liquids: compressibility and gas and liquid separations
… in ethane/ethene separation by pure gas solubility measurements. Furthermore, no porous liquids have previously been explored to perform liquid-liquid separations. Hydrophobic Type 3 porous liquids were developed for liquid-liquid separation specifically mono-ethylene glycol (MEG) from …

The precipitation of candidate drugs on mixing DMSO stock solutions with aqueous buffers
… analyses, such as bioassay screening and some solubility screens. Precipitation from these mixtures, whilst a recognised issue, has little in the way of published work. This thesis explores in detail the precipitation of three poorly water soluble, commercially available drug molecules, namely …

Synthesis, characterization, and anticancer evaluation of novel gold(I) phosphine thiolate complexes : solubility, cellular uptake, and cytotoxicity.
… aspect of drug development – accurate solubility determination – was addressed using ICP-MS. This technique allowed for direct measurement of gold concentration in saturated solutions, providing precise solubility values in both water and McCoy's 5A cell culture medium supplemented with …

Crystallization of calcium sulphate during phosphoric acid production : improving filtration through improvement in particle shape and size distribution
… which be written in terms of the solubility product ratio, as governed by nonideal thermodynamics, requires the computation of activity coefficients as well as free ion concentrations. For this purpose, the mixed solvent electrolyte (MSE) model is utilized to capture the solution …

Exploring Sulfur Recovery in a Eutectic Mixture of Biphenyl and Diphenyl Ether
… To support further design of the process, sulfur solubility in the eutectic mixture was measured from 25 to 130 °C. High-pressure densities of sulfur in the eutectic solvent were measured from 25 to 100 °C and pressures up to 40MPa to determine the volumetric properties of dissolved sulfur. An …

Halogens and trace elements in subduction zones
… fluids at high temperatures and pressures. The solubility of fluorine and chlorine in upper mantle minerals (forsterite, enstatite and pyrope) and halogen partitioning between aqueous fluids and these minerals were investigated by piston-cylinder experiments at 1100 °C and 2.6 GPa. Chlorine …

Evaluating the Potential of Scaling due to Calcium Compounds in Hydrometallurgical Processes
… data such as mean activity, heat capacity and solubility data in simple binary and ternary systems. Moreover, a number of experiments were conducted to investigate the chemistry of calcium sulphate hydrates in laterite pressure acid leach (PAL) solutions, containing Al2(SO4)3, MgSO4, NiSO4, …
