Results are presented for the aggregation number of sodium dodecyl sulfate (NaDS) micelles determined by the quenching of alkyl derivatives of the fluorescent probe ruthenium(lI)tris(bipyridyl). A significant increase in the apparent aggregation number was observed for determinations using probes wi
The effect of medium chain length alcohols on the micellar size and shape of sodium dodecyl sulfate in electrolyte solutions has been investigated by means of small angle neutron scattering (SANS), dynamic light scattering (DLS), and viscosity measurements. The surfactant content was kept constant t
