The capability of the extended forms, of two well established cosolvency models, i.e. the combined nearly ideal binary solvent/Redlich-Kister equation and the modified Wilson model, used to predict the solute solubility in non-aqueous ternary solvent mixtures is presented. These predictions are based on the measured solubilities of anthracene in binary solvent mixtures. As a result the values o...

The polarographic study of Cd(II) with L-Tyrosine has been investigated in aqueous organic solvent mixtures at 300K. The Dimethyl sulphoxide and Dimethyl formamide solvents have been used with water to study the effect of solvents on the stability of complexes. Cadmium(II) formed 1:1, 1:2 and 1:3 complexes with L-Tyrosine in the aqueous-organic solvent mixture i.e. DMSO and DMF. The stability c...

Cellular metabolome analysis by chromatography-mass spectrometry (MS) requires prior metabolite extraction. We examined a diversity of solvent systems for extraction of water-soluble metabolites from Escherichia coli. Quantitative yields of approximately 100 different metabolites were measured by liquid chromatography-tandem MS and displayed in clustered heat map format. Many metabolites, inclu...

Abstract Viscosity is the resistance of a material to continuous deformation exerted by shear force. High viscosity, which sometimes greater than 1 million mPa s, at initial reservoir conditions, major challenge recovery, production, and transportation bitumen. Addition organic solvents or diluents with bitumen leads significant viscosity reduction forms basis for steam/solvent-assisted recover...

Previously, we described a coarse-graining method for creating local density-dependent implicit solvent (DDIS) potentials that reproduce the radial distribution function (RDF) and solute excess chemical potential across a range of particle concentrations [E. C. Allen and G. C. Rutledge, J. Chem. Phys. 128, 154115 (2008)]. In this work, we test the transferability of these potentials, derived fr...

Based on hard-sphere limit of binary mixtures with different molecular size of components a theory has been developed for calculating activities of solvents in polymer/solvent mixtures. The theory considers various chain configurations for polymer molecules, varying from extended chain to the coiled chain. According to this theory the activity of solvent can be calculated from molecular weights...

Imidazolium-based chloride ionic liquids (ILs) have exhibited remarkable performance in several important applications such as biomass dissolution and extraction, but their large viscosity is a non-negligible problem. Adding molecular co-solvents into chloride ILs is effective in reducing viscosity; nevertheless, understanding of the accompanied change of thermodynamic polarity is quite few. Th...

the solubility of naproxen in binary mixtures of polyethylene glycol 200 (peg 200) + water at the temperature range from 298.0 k to 318.0 k were reported. the combinations of jouyban-acree model + van’t hoff and jouyban-acree model + partial solubility parameters were used to predict the solubility of naproxen in peg 200 + water mixtures at different temperatures. combination of jouyban-acree m...
