Use of infrared bands of the surfactant headgroup to identify mixed surfactant structures adsorbed on Titania
Article Abstract:
The study identifies the mixed surfactant structures formed on charged TiO2 particles using the attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR). It concludes that subtle changes in the infrared bands due to surfactant headgroup provide a unique insight to the aggregated structures of mixed surfactants on charged metal oxide surfaces.

Effect of an anionic surfactant on the complexation of some nonionic polymers with iodine in aqueous media
Article Abstract:
The complex formation of water soluble nonionic polymers like polyvinylalcohol (PVA), polyvinylpyrrolidone (PVP) and hydroxypropyl cellulose (HPC) with iodine is studied in aqueous sodiumdodecylsulfate (SDS) solution. The formation of iodine-PVP/HPC complex is favored by the presence of SDS monomers.

Comparing effectiveness of rhamnolipid biosurfactant with a quaternary ammonium salt surfactant for hydrate anti-agglomeration
Article Abstract:
The effectiveness of different surfactants with a quaternary ammonium salt is examined The studies have shown that a rhamnolipid biosurfactant can be effective to a concentration of 0.05 wt % and the biosurfactant has formed a less stable emulsion, making it very desirable for hydrate application.
