“…Picolinium salts have, in many cases, been used as intermediates for the preparation of donor-acceptor molecules for the construction of promising photo- and electro-active materials [ 29 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. In addition, their typical physicochemical features such as surface activity and micellization have been intensively studied in the line of their possible application [ 39 , 40 , 41 , 42 , 43 , 44 ]. For instance, N -( n -hexadecyl)- and N -( n -heptadecyl)-3-methylpyridinium bromide or 1-methyl-3-octylpyridinium alkyl sulfate were found to be effective for micelle-based drug delivery to improve drug solubility and the bioavailability of anionic drugs and metal complexes [ 28 , 43 ].…”

“…The surface activity of ILSs solutions can be characterized by the adsorption efficiency (pC 20 ) and the surface pressure (p CMC ). The adsorption efficiency can be calculated by the following equation: 18,27,28 The maximum surface excess (G MAX ) and the minimum surface cross sectional area (A MIN ) of the ILSs are calculated by the following eqn ( 5) and ( 6), respectively. 18,27,28…”

“…Surface and interfacial tension measurements were obtained Tensiometer K6 Krüss, Germany, (Du Nouy tensiometer with Platinum-Iridium ring) in Egyptian Petroleum Research Institute (EPRI). [42,43]. Interfacial tension was measured for surfactant-oil system at 25 o C with a 0.1 % surfactant solution.…”
