We have analyzed the electrical conductivity of a linear high charge density polyelectrolyte aqueous solution, finding that the counterion association order follows the same pattern as that described for a cyclic monomeric ...

Counterion condensation to poly(1,1-dimethyl-3,5-dimethylene piperidinium) through the behavior of the relative conductimetric interaction parameter f* in methanol/water solutions is analyzed. The trend of this parameter ...

We developed a Monte Carlo systematic study into the effect of counterion condensation on the polyelectrolyte adsorption process on charged surfaces. Polyelectrolyte is modeled as a full-flexible chain whose size is ...

The effect of the nature of the medium on the chloride and bromide condensation to a cationic polyelectrolyte was studied. Methanol/water mixtures were used as solvent in order to vary continuously the properties of the ...

Measurements of the electrical equivalent conductivity of potassium salts of poly(maleic acid-co-1-olefins), PA-nK(2) with n = 12, 18 has been carried out in methanol-water mixtures in the whole range of composition. The ...

For RNA to fold into compact, ordered structures, it must overcome electrostatic repulsion between negatively charged phosphate groups by counterion recruitment. A physical understanding of the counterion-assisted folding ...

Measurements of surfactant ion (tetradecyltrimethylammonium) and counterion (bromide) activities in binary tetradecyltrimethylaznmonium bromide (TTAB)-Brij 35 surfactant mixtures have been performed by using ion-specific ...
