Isothermal titration calorimetric and electromotive force studies on binding interactions of hydrophobic ethoxylated urethane and sodium dodecyl sulfate of different molecular masses

Article Abstract:

The isothermal titration calorimetric (ITC) and surfactant-selective electrode (EMF) techniques were used for examining the interactions between hydrophobic ethoxylated urethane (HEUR) and sodium dodecyl sulfate (SDS). The comparison of isothermal titration of sodium dodecyl sulfate (SDS) into hydrophobic ethoxylated urethane (HEUR) solutions and hydrophobic ethoxylated urethane (HEUR) into sodium dodecyl sulfate (SDS) micellar solutions is discussed.

Mesostructured Fe oxide synthesized by ligand-assisted templating with a chelating triol surfactant

Article Abstract:

The properties and synthesis of sulfate- and phosphate-free mesostructures iron oxide prepared using a chelating triol surfactant are illustrated. The results show that other chelating oxygen surfactants may yet be successful in synthesizing stable mesoporous iron oxide with surface areas comparable or higher than other samples of mesoporous iron oxide previously synthesized.

Synthesis of highly-active sulfate promoted rutile titania nanoparticles with a response to visible light

Article Abstract:

A novel, simple, and effective method to produce highly active sulfate-promoted rutenile TiO(sub 2) that can be efficiently operated in the visible light region by an in situ sulfation method is successfully developed. The results show that sulfate species are sensitive to the variation of calcination temperature.
