  • Title: Surface dilational rheology of mixed adsorption layers at liquid interfaces.
    Author: Aksenenko EV, Kovalchuk VI, Fainerman VB, Miller R.
    Journal: Adv Colloid Interface Sci; 2006 Sep 25; 122(1-3):57-66. PubMed ID: 16884674.
    Abstract:
    The dilational rheology for mixed solutions of surface active compounds is easy to measure with existing methods, however, there are very few attempts only to analyse the resulting data on the basis of a theoretical model. Models by Jiang et al., Joos, and by Lucassen and van den Tempel (for single compounds) are compared here and applied to experimental data. The mentioned models converge to each other after some small modifications and represent a very good scientific background for studies of the mechanical behaviour of mixed adsorption layers. As example, the experimental results for mixed solutions containing a globular protein (beta-lactoglobulin) and a non-ionic surfactant (alkyl dimethyl phosphine oxide) are analysed by the obtained dependencies, using some new proposed numerical procedures.
