The interfacial tensions and dilational properties of adsorbed films of two zwitterionic surfactants with different hydrophobic groups, alkyl sulphobetaine (ASB) and benzyl substituted alkyl sulphobetaine (BSB), at the decane–water interface have been investigated by the drop shape analysis method. The influences of dilational frequency and bulk concentration on the interfacial dilational modulus...
Sorption of fluids during typical wetting experiments on natural fibers produces a zero receding contact angle situation, leading to an incomplete analysis of their wetting behavior. An acoustic vibration method was used to measure “equilibrium” contact angles on natural bamboo fibers. The correctness of the technique is verified by performing the experiment with polyethylene terephthalate (PET) fibers...
The formation of O/W nanoemulsions by the phase inversion temperature (PIT) method has been studied in water/Miglyol 812 systems. The effects of a hydrophobic co-surfactant (Igepal) and a hydrophobic drug (α-tocopherol) on tuning and optimising the PIT, which is essential for industrial processes, were studied. The hydrophilic poly-oxyethylated surfactant used was Kolliphor HS15. For these systems...
Herein were performed theoretical and experimental studies about the performance of the cationic surfactant docecyltrimethylammonium chloride (C 12 TAC) on the enhancement of the oil recovery factor (ORF) from heavy oil-impregnated calcite cores. The interaction energies between C 12 TAC and either of some molecules present in oil such as an asphaltene (Asph), a resin (Res) or an octanoic...
