TL;DR: The use of surface tensiometry and rheometry of mixed protein/surfactant mixed layers is demonstrated as a new tool in the diagnostics of various diseases and for monitoring the progress of therapies.

TL;DR: In this paper, the authors derived asymptotic solutions of the adsorption kinetic equations for the liquid phase interface in the regions of infinitely small and infinitely great surface lifetimes (t) for the cases of one and of a few surfactants, on non-deforming and deforming surfaces, under nonstationary, stationary and quasi-stationary conditions.

TL;DR: Drop and bubble shape tensiometry is a modern and very effective tool for measuring dynamic and static interfacial tensions as mentioned in this paper, and the theoretical basis of the method, the fitting procedure to the Gauss-Laplace equation and the key procedures for calibration of the instrument are analysed and described.

TL;DR: In this article, the physicico-chemical properties of the aqueous solutions of three different types of hydroxypropyl methylcellulose (HPMC 2208, HPMC 2906 and HPGC 2910) and those of oil-in-water emulsions containing medium-chain triglycerides (MCT) as dispersed phase were investigated.

TL;DR: For the most frequently studied water/air interface, the maximum oscillation frequency is of the order of 1 Hz, although much higher frequencies are technically feasible by the existing profile analysis tensiometers as discussed by the authors.
