Abstract. Barite formation is of concern for many utilisations the geological subsurface, ranging from oil and gas extraction to geothermal reservoirs. It also acts as a scavenger mineral retention radium within nuclear waste repositories. The impact its precipitation on flow properties has been shown vary by orders magnitude, emphasising need robust prediction models. An experimental flow-thro...

Extended Hildebrand solubility approach is used to estimate the solubility of nabumetone in binary solvent systems. The solubility of nabumetone in various propylene glycol-water mixtures was analyzed in terms of solute-solvent interactions using a modified version of Hildebrand-Scatchard treatment for regular solutions. The solubility of nabumetone in the binary solvent, propylene glycol-water...

Pharmaceutical field is widely focusing on solubility parameter models to select solvent or non-solvent that can enhance solvency of drug. Solubility Parameter very useful concept in understanding the mechanism and behavior with their applications pharmaceuticals open door research having focus theoretical considerations solubility. Hildebrand Hansen are frequently used identify solvents.

4 Mineral aerosol deposition is recognized as the dominant source of iron to the open 5 ocean and solubility of iron in the dust aerosol is highly uncertain. Previous solubility 6 estimates range widely from 0.01-80%. We developed two conceptual models to solve 7 for the solubility of different particle sizes—diffusion-controlled model and surface8 controlled model. We are able to produce time ...

A method is described for estimating solubility by fitting both solute and solvent properties in a single equation. The method is illustrated by examining the solubilities of five rare gases (He, Ne, Ar, Kr, Xe) and five 6permanent7 gases (O2, N2, CH4, CF4, SF6) in either n-alkane (C5H12 to C16H34) or alkan-1-ol (CH3OH to C11H23OH) solvents. Generally, the correlation (R2) values of the fits ac...

introduction : solubility of root filling materials is heavily influenced by the environment they are in contact with. this study compared the solubility of proroot mta in deionized water and synthetic tissue fluid. materials & methods: forty specimens of prepared mta were immersed in deionized water and synthetic tissue fluid (20 samples each). the solubility was assessed after 7 and 28 days. ...

this study presents the influence of hydroxypropyl-β-cyclodextrin (hpbcd) on the aqueous solubility of acyl esters of cyproterone. first, a number of esters of cyproterone were synthesized. then the phase solubility analysis of the compounds in the presence of hpbcd was investigated in phosphate buffer solution at a ph of 7.4. to gain a better understanding of the complexation mechanism, the sy...
