Low-concentration tracer tests to measure air-water interfacial area in porous media

Chemosphere, 2020
The aqueous-based interfacial tracer method employing miscible-displacement tests is one method available for measuring air-water interfacial areas. One potential limitation to the method is the impact of tracer-induced drainage on the system. The objective of this study was to investigate the efficacy of a low-concentration tracer test method for ...

Interfacial assignment of branched-alkyl benzene sulfonates: A molecular simulation

AIP Advances, 2015
A molecular dynamics simulation was conducted to analyze orientations of sodium branched-alkyl benzene sulfonates molecules at nonane/water interface, which is helpful to design optimal surfactant structures to achieve ultralow interfacial tension (IFT).
