Activity coefficients for each of the components, urea and sodium sulfate, in their ternary mixtures with water have been obtained using the isopiestic vapor pressure method over the concentration ranges 0 to 19.4 molal urea and 0 to 2.4 molal Na2S04. At the lower molalities of the solutes, there is mutual salting-in of the components which changes to salting-out at 0.4 molal Na2SQ4 and 5 molal...
Morphologies Observed in Ultraflexible Microemulsions with and without the Presence of a Strong Acid
We show that three different morphologies exist near the two-phase boundary of ternary systems containing a hydrotropic cosolvent. Based on synchrotron small- and wide-angle X-ray scattering combined with molecular dynamics, we rationalize the specific scattering signature of direct, bicontinuous, and reverse mesoscale solubilization. Surprisingly, these mesostructures are resilient toward stro...
Great Salt Lake, Utah, is a large, terminal, hypersaline lake consisting of a northern more saline arm and a southern arm that is less saline. The southern arm supports a seasonally abundant fauna of low diversity consisting of brine shrimp (Artemia franciscana), 7 species of brine flies, and multiple species of algae. Although fish cannot survive in the main body of the lake, the lake is highl...
The effect of salting by different salt composition on fatty acid profile studied in hot smoked Black and Caspian Sea sprat, Clupeonella cultriventris. After initial prepare activities, samples were exposed to brining process within two salt concentrations including of 100 % NaCl (treatment 1 or T1) and 75 % NaCl- 25 % KCl (treatment 2 or T2) under 15% brine solution for 3 hrs. The smoking proc...
A small but significant number of sinkholes and other karst phenomena in southeastern New Mexico are of human origin and are often associated with solution mining of salt beds in the shallow subsurface. In 2008 two brine wells in a sparsely populated area of northern Eddy County, New Mexico, abruptly collapsed as a result of solution mining operations. The well operators had been injecting fres...
Large quantities of oil and gas well brines are produced annually in Ohio. This paper presents chemical parameters measured for a Wayne County, Ohio, oil well brine and reports the effects of several incremental brine concentrations on the germination and seedling development of soft red winter wheat (Triticum aestivum), soybeans (Glycine max), tall fescue (Festuca arundinacea), garden peas (Pi...
The permanent ice cover of Lake Vida (Antarctica) encapsulates an extreme cryogenic brine ecosystem (-13 °C; salinity, 200). This aphotic ecosystem is anoxic and consists of a slightly acidic (pH 6.2) sodium chloride-dominated brine. Expeditions in 2005 and 2010 were conducted to investigate the biogeochemistry of Lake Vida's brine system. A phylogenetically diverse and metabolically active Bac...
Industrial scale injection of anthropogenic carbon dioxide into the crustal lithosphere has been proposed to reduce atmospheric accumulation. Much of this injection is expected to occur in saline reservoirs. An understanding of two-phase brine-CO2 flow is necessary for predicting storage capacity, fluid migration, and injectivity in geologic reservoirs. Additionally, the chemical reactivity of ...
The complexity and dynamics of microbial metagenomes may be evaluated by genome size, gene duplication and the disruption rate between lineages. In this study, we pyrosequenced the metagenomes of microbes obtained from the brine and sediment of a deep-sea brine pool in the Red Sea to explore the possible genomic adaptations of the microbes in response to environmental changes. The microbes from...
