The effects of ionic strength and solvent polarity on the equilibrium distribution of fluorescein (FL) and FITC-dextran between the interior of polyelectrolyte multilayer microcapsules filled with negatively charged strong polyelectrolyte and the bulk solution were systematically investigated. A negatively charged strong polyelectrolyte, poly(styrene sulfonate) (PSS), used for CaCO3 core fabric...

The complexation of zinc (II) with dopamine has been investigated by spectrophotometric measurements in mixed solvent system at an ionic strength of 0.2 mol*dm-3 sodium chloride, employed (25± 0.1° C) at pH ranges of ~6 to ~7 with a high ratio of ligand to metal.

Deterioration of long-term dentin adhesion durability is thought to occur by hydrolytic degradation within hydrophilic domains of the adhesive and hybrid layers. This study investigated the hypothesis that priming the collagen network with an organic solvent displace water without collapse and thereby obtain good bond strength with an adhesive made of hydrophobic monomers and organic solvents. ...

the effect of different solvent systems on the extraction of antioxidant and anti radical agents of grape seed was studied. for this purpose 6 different solvent systems with similar polarity and different selectivity were used to prepare grape seed extract. extraction efficiency, reducing activity, radical scavenging property and the effect of each extract on the increase of thermal resistance ...

The thermodynamics of fluoride ion solvation in nonaqueous and mixed aqueous solvents are reviewed. Gibbs energies of transfer , at^ O (F ) H20+ , indicate that the solvation of the fluoride ion is dominated by hydrogen bonding. Thus, at^ o ( ~ ) H 2 0 S is unfavourable for virtually all solvents, especially dipolar aprotics, and correlates well with solvent acceptor strength. The corresponding...

Interactions of DNA oligomers with two categories of semiconducting nanostructureschalcogenide quantum dots (QDs) and boron nitride nanotubes (BNNTs)owing to their widespread presence in bioinspired processes are investigated using the first-principles density functional theory and continuum solvent model. The chalcogenide QDs interact strongly at their metal centers featuring electrostatic i...

Understanding working principles and thermodynamics behind phase separations, which have significant influences on condensed molecular structures their performances, can inspire to design fabricate anomalously desirably mechanoresponsive hydrogels. However, a combination of techniques from physicochemistry mechanics has yet been established for the separation in In this study, thermodynamic mod...
