Ellipsometric investigations of mixed adsorption layers of polyallylamine hydrochloride with sodium dodecyl sulphate at the water/air interface

Mixed Adsorption Layers Formed at the Electrode – Solution Interface

Adsorption of sophorolipid biosurfactants on their own and mixed with sodium dodecyl benzene sulfonate, at the air/water interface.

The adsorption of the lactonic (LS) and acidic (AS) forms of sophorolipid and their mixtures with the anionic surfactant sodium dodecyl benzene sulfonate (LAS) has been measured at the air/water interface by neutron reflectivity, NR. The AS and LS sophorolipids adsorb with Langmuir-like adsorption isotherms. The more hydrophobic LS is more surface active than the AS, with a lower critical micel...

Composition of mixed adsorption layers and micelles in solutions of sodium dodecyl sulfate and dodecyl acid diethanol amide

The surface tension isotherms of dodecyl acid diethanole amide (DADA), sodium dodecyl sulfate (SDS) and their mixtures at different molar ratios are measured by the Wilhelmy-plate method. The isotherms are analyzed by the theory of nonideal interactions in binary surfactant mixtures (NIBM) and by the nonideal multicomponent mixed micelle model (NMMM). The molecular interaction parameters (MIP) ...

FOLDING OF THE INTERACTION OF HISTONE HI WITH SODIUM N-DODECYL SULPHATE

The effects of sodium n-dodecyl sulphate (SDS) on the structure of histone HI has been studied by a combination of e:quilibrium dialysis, U.V. spectroscopy ; polyacrylamide gel electrophoresis, protein titration and viscometery techniques using, 2.5 mM phosphate buffer, pH 6.4. The interaction of H, and SDS in contrast tomanyothel-protein-SDS interactions is organized between V 40 to 70. A...

THERMODYNAMIC STUDIES OF THE INTERACTION OF SODIUM N-DODECYL, SULPHATE WITH CALF - THYMUS WISTONE H3

The binding of Sodium n-dodecyl sulphate (SDS) to histone H3 was studied in the pH range 3.2-10 by equilibrium dialysis at 27? and 3 7 ?c .T he binding data have been used to obtain the Gibbs free energy of interaction using a theoretical model of the Wyman binding potential; and the enthalpy of interaction from the temperature dependence of theequilibriumconstantsfronr theVan't Hoff re1ati...
