Due to the large surface area of the layered silicate nanoparticles, the in situ formed graft efficiently reduces the interfacial tension
, as a result of its migration to the interface of incompatible phases [28, 40].
The high concentration of Polyglycerol polyricinoleate lowers the interfacial tension
and the droplets became weak and easily deformable, hence the flow behavior was more pronounced in high concentration of Polyglycerol polyricinoleate hence, the results are according to literature [26, 27].
The decreasing of interfacial tension
on border "water/diesel fuel" in the presence of 0.
Surprisingly, there is relatively little published information on the surface and interfacial tensions
of native and modified starches and existing data is conflicting or incomplete.
Where (gamma) sd and (gamma) sc are the interfacial tensions
of the respective boundary of solid/disperse phase and solid/continuous phases, and (gamma) cd is the interfacial tension
between the two liquid phases.
For surface properties: sweet almond oil / whey, all interfacial tensions
are lower than that found obtained for sweet almond oil/water is 45 Dynes/cm whose the values of the interfacial tension
varies from one whey to another: 35.
It is also known that the attainment of three phases in mixtures of oil, water and an ionic surfactant produces low and ultralow values of the interfacial tension
between the immiscible phases (Salager et al.
Schulman et al have postulated that interfacial tension
is a key process in microemulsion formation and that the main role of the surfactant is to reduce the interfacial tension
to very low values [13, 14].
Among the topics are effects of surface structure on the behavior of a heating contact line, the mechanistic modeling of dynamic vapor-liquid interfacial tension
in complex petroleum fluids, measuring wettability and evaluating cleanliness without substantial cost, modulating the surface properties of reactive polymers by photo-Fries rearrangement, super-hydrophobic aluminum surfaces obtained by chemical etching, and the adsorption of surfactants at hydrophobic and super-hydrophobic solid surfaces.
Surfactants lower the surface tension of a liquid and the interfacial tension
, or resistance, between two liquids, or between a liquid and a solid.
Experimental Study of Transient Interfacial Tension
for Alkane-Water-Triton X-100 System using the Emergent Drop Technique
In the inversion region the ultra-low interfacial tension
between water and oil phase allows the formation of very fine oil/water emulsion droplets.
