The precise control of crystallization is a key issue in providing a high quality crystalline product. It has to be achieved by, among other means, a proper choice of the solution processing temperature, which is determined on the basis of the metastable zone width and type of solubility curve. In this article experimental data for potassium chloride solution density, as a function of temperatu...

Abstract. This study evaluates the potential usefulness of halogenated compounds HCFC-22, HCFC-141b, HCFC-142b, HFC-134a, HFC-125, HFC-23, PFC-14, and PFC-116 as oceanographic transient tracers to better constrain ocean ventilation processes. We do this mainly in terms four aspects characteristics tracers: input function (including atmospheric history historical surface saturation), seawater so...

Utilization of ionic liquids (ILs) for carbon dioxide (CO2) capture is continuously growing, and further understanding the factors that influence its solubility (notably new ILs) crucial. Herein, CO2 absorption two 1,2,4-triazolium-based ILs was compared with imidazolium-based Ils different anions, namely bis(trifluoromethylsulfonyl)imide, tetrafluoroborate, glycinate. The capacity determined u...

The solubility enhancement of poorly soluble compounds is an important task in pharmaceutical technology as it leads to better bioavailability and a more efficient application. Fused dispersions (FDs) of simvastatin (SIM) using PEO-PPO block copolymer were prepared which paved the way for the formation of an amorphous product with enhanced dissolution and bioavailability. The accumulative solub...

Ocean acidification and decreasing seawater saturation state with respect to calcium carbonate (CaCO3) minerals have raised concerns about the consequences to marine organisms that build CaCO3 structures. A large proportion of benthic marine calcifiers incorporate Mg into their skeletons (Mg-calcite), which, in general, reduces mineral stability. The relative vulnerability of some marine calcif...

From the application of chemical thermodynamics a quartz solubility regression expression along the water-vapor saturation curve for whole range of temperature from 0 to 374oC was developed. The equation is the following ( ) ( ) 08 . 0 88 . 4 ) ( 7 . 31 7 1175 ) ( log 2 ± + ± ⋅ − = K T ppm SiO The correction of total discharge silica composition from a well for the vapor fraction in the geother...

BCS class II drugs associated as they are with low aqueous solubility and bioavailability pose an alarming challenge for the pharmaceutical scientists from the point of view of formulation by conventional methods. That is all the more surprising as around forty percent of the new generated drugs exhibit poor water solubility. However , the formulation of such drugs is now being increasingly don...

The effects of 22 lyotropic salts on the polymerization of deoxygenated sickle hemoglobin (deoxy-Hb S) were evaluated. The equilibrium solubility was measured as the saturation concentration, cBat, after phase separation by centrifugation at 30°C. The linear plots of csat uersus salt concentration allowed the assignment of particular cations or anions as either salting-in (csat increased) or sa...

Rates of reduction of Fe(III) oxyhydroxides by the bacterium Shewanella putrefaciens were measured as a function of the bacterial density and the Fe(III) substrate concentration. The results show that an earlier reported positive correlation between the solubility products (Kso) and the maximum cell-specific reduction rates (vmax) of predominantly poorly crystalline Fe(III) oxyhydroxides also a...

Elevation of 2,3-bisphosphoglycerate (2,3-DPG) in sickle erthrocytes (SS RBCs) and concomitant acidification of the cell interior promote polymerization by decreasing the solubility (csat) of deoxyhemoglobin S. The antisickling effect of 2,3-DPG depletion was evaluated after activation of the 2,3-DPG phosphatase activity of bisphosphoglycerate mutase by glycolate-2-phosphate, leading to rapid l...
