cationic radical, MV", with sodium dodecyl sulfate (SDS) near or below the critical micelle concentration (cmc) of the surfactant is considerably different from ours. We would like to present some comments on this, based on the results of our publication2 and other experimental results. One major contention is on the interaction of MV" radical ...
Oct 10, 2018· Wettability alteration of carbonate reservoirs from oilwet to waterwet is an important method to increase the efficiency of oil recovery. Interaction between surfactants and polymers can enhance the effectiveness of surfactants in EOR applications. In this study, the interaction of polyethylene glycol (PEG) with an ionic surfactant, sodium dodecyl sulphate (SDS), is evaluated on an oilwet ...
The micelles formed by sodium dodecyl sulfate (SDS) are studied in aqueous solutions at 294 K as a function of nominal SDS concentration (C) using positron lifetime spectroscopy. In a fourcomponent analysis of the data, it appears that the lifetime (τ3) of the positronium triplet state (oPs) in the aqueous phase decreases significantly with increasing C. Preliminary results on sodium ...

The primary ingredients are polyacrylamide and sodium dodecyl sulfate—SDSPAGE refers to sodium dodecyl sulfatepolyacrylamide gel electrophoresis. In order to visualize the results, proteins separated via SDSPAGE are transferred to a nitrocellulose membrane, where they are probed with antibodies for a specific protein of interest.
Several pieces of experimental evidence of condensation of soluble surfactant molecules, cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS), into the air/water surface region from the bulk solution are presented at different added salt concentrations in order to substantiate that the concentrated molecules do not locate just at the air/solution interface.
A critical examination of the pathway of adsorption for the interactions of SDS with preadsorbed PAMAM monolayers and premixed PAMAM/SDS solutions with hydrophilic silica revealed that nonequilibrium effects are important only in the latter case, and the application of a thermodynamic model to such experimental data would be inappropriate.
