Estimation of interfacial tension between organic liquids and water

Determination of Water-Oil Interfacial Area during 3-Phase Gravity Drainage in Porous Media

“…1) and γ gw = 36 mN/m (18). γ go has been previously tabulated and found to be approximately 24 mN/m (22). The value of the initial spreading coefficient, using [3], is 3 mN/m.…”

Flow dynamics and potential for biodegradation of organic contaminants in fractured rock vadose zones

“…Water is intermediately wetting to epoxy (contact angle ranges from 57°to 65°, Geller et al, (1996)), which somewhat reduces capillary forces and trapping of the non-wetting phase compared to strongly water-wet systems. Most common aquifer minerals, such as quartz, carbonates and sulfates, are strongly water-wet (Demond and Lindner, 1993); however, natural hydrophobic organic materials and anthropogenic organic compounds on the mineral surface may create conditions of neutral nettability.…”

Silicon-modified carbohydrate surfactants. IV. The impact of substructures on the wetting behaviour of siloxanyl-modified carbohydrate surfactants on low-energy surfaces

“…In a number of cases major deviations of the experimental results from theoretical predictions have been found. 35 Therefore the authors are aware that the donor-acceptor and Lifshitz-van der Waals portions of the surface tension and solid/liquid interfacial tension do not entirely describe the absolute polarity of a single molecule. Instead they reflect its measurable interactions with other surfactant molecules or condensed phases.…”
