The vesicle-to-micelle transition (VMT) was realized in catanionic surfactant systems by the addition of two kinds of bile salts, sodium cholate (SC) and sodium deoxycholate (SDC). It was found that steric interaction between the bile salt and catanionic surfactant plays an important role in catanionic surfactant systems that are usually thought to be dominated by electrostatic interaction. The...

The solubility of sodium oxalate was measured in kraft black liquors at temperatures 115 °C to 140 with dry solid contents 45% 70%. composition studied were varied respect concentration by addition salts. increased increasing temperature and decreased liquor contents. data showed no dependence on the a constant sodium. A mathematical expression derived validated from experimental conditions inv...

The microrheology of cationic micellar solutions has been investigated as a function of added organic salts using quasielastic light scattering (QELS). Two organic salts, sodium p-toluene sulfonate and sodium salicylate, were used to induce microstructural changes in cetyl trimethylammonium bromide (CTAB) micelles. The mean-squared displacement (MSD) of polystyrene probe particles embedded in C...

1. Fibrin clots prepared in the absence of calcium can be dissolved in solutions of lithium chloride and bromide and sodium bromide and iodide, as well as of guanidine hydrochloride and urea. These salts do not denature fibrinogen under the same conditions of concentration, temperature, and time. Sedimentation experiments on the fibrin solutions show in each case a single sharp peak with a sedi...

The enthalpies of dilution of solutions of two bile salts in water and aqueous NaCI were measured over a range of solute concentrations encornpassing the critical micellization concentrations (c.m.c.). The compounds were sodium taurodeoxycholate and sodium tauro choiate. An isoperibolic reaction calorimeter was used. The observed changes of enthalpies of dilution as a function of surfactant and...

Inhibition of recombinant D-amino acid oxidase from Trigonopsis variabilis (TvDAAO) activity in the presence of different sodium salts and potassium chloride is reported. A competitive inhibition pattern by sodium chloride was observed, and an inhibition constant value of K(i) = 85 mM was calculated. Direct connection of NaCl inhibition with FAD cofactor dissociation was confirmed by measuring ...
