Dynamic surface properties of adsorbed protein solutions: BSA, casein and buttermilk

Monodispersed microbubble formation using microchannel technique

“…Measurements by the capillary-wave method (Sasaki et al, 1977) also yield an adsorption relaxation time on the order of 10 Ϫ3 s for SDS in the concentration ranges similar to those used in our experiment (Sasaki et al, 1977). On the other hand, it was reported that d for BSA of 4.8 g/L concentration was 1.3 s (Serrien et al, 1992).…”

Development of a Constant Surface Pressure Penetration Langmuir Balance Based on Axisymmetric Drop Shape Analysis

“…In this case fitting may be still possible but considerably more complicated. But if adsorption is irreversible, as may be the case for some proteins (see, e.g., 21,27), no such relation can be obtained by fitting of the experimental data, and the existing theoretical models are not adequate for a sufficiently general prediction of protein film behavior. Therefore, computer simulations are recommended only for some situations, where a functional relation between measurement and control variable can easily be obtained.…”

Formation Kinetics and Viscoelastic Properties of Water/Crude Oil Interfacial Films

“…Different types of model of the kinetics of adsorption of molecules in the film may be used to adjust the measurements. Firstly a monoexponential model was considered as it has been proposed by Serrien et al [31] for the proteins' adsorption process: (5) where γ eq is the interfacial tension at equilibrium, γ 0 is the interfacial tension at time zero, and τ is the characteristic time for the reorganization process of the interfacial film. It can be noticed that the regression line that follows the monoexponential model does not perfectly fit the experimental points.…”
