Surfactant adsorption kinetics in microfluidics [PDF]

Proceedings of the National Academy of Sciences, 2016
Significance Surfactant adsorption to interfaces is a dynamic process of relevance for foaming, emulsification, and detergency. Although the process has been described for centuries now, the rational measurement of adsorption and desorption constants, as well as the modeling of the binding mechanism, is still subject to many ...
