Thermodynamics and Kinetics of Mixed Protein/Surfactant Adsorption Layers at Liquid Interfaces

R. Miller E.V. Aksenenko V.S. Alahverdjieva V. B. Fainerman Cs. Kotsmár

This chapter describes the equilibrium state of mixed protein/surfactant adsorption layers and the mechanisms of their formation by thermodynamic and kinetics theories. Measurements of the equilibrium adsorption state are surface or interfacial tension isotherms. While tensiometry allows following the formation of adsorption layers over a certain time interval, dilational rheology provides information on the response of the interfacial layer to small perturbations. There are additional studies which do not provide quantitative but qualitative information about protein adsorption layers. Surface and interfacial shear rheology, for example, probes the formation of structures within the adsorption layers. The chapter also shows that the general features of protein adsorption at the water—air surface and at water—oil interfaces are similar; however, there are significant quantitative differences. This is of great relevance as proteins and their mixtures with low-molecular-weight surfactants are frequently used for the stabilization of foams and emulsions.

On the Dissolution of Vapors and Gases

Langmuir (2006)

N. Wüstneck R. Wüstneck U. Pison Helmuth Möhwald

The captive bubble technique in combination with axisymmetric drop shape analysis (ADSA-CB) and with micro gas chromatography is used to study the dynamics of dissolution of different gases and vapors in water in situ. The technique yields the changes in the interfacial tension and bubble volume and surface. As examples, the dissolution of methanol and hexane vapors, inhaled anesthetic vapors, and gases, that is, diethyl ether, chloroform, isoflurane, enflurane, sevoflurane, desflurane, N2O, and xenon, and as nonimmobilizers perfluoropentane and 1,1,2-trichloro-1,2,2-trifluoro-ethane (R113) were investigated. The examination of interfacial tension-time and bubble volume-time functions permits us to distinguish between water-soluble and -insoluble substances, gases, and vapors. Vapors and gases generally differ in terms of the strength of their intermolecular interactions. The main difference between dissolution processes of gases and vapors is that, during the entire process of gas dissolution, no surface tension change occurs. In contrast, during vapor dissolution the surface tension drops immediately and decreases continuously until it reaches the equilibrium surface tension of water at the end of dissolution. The results of this study show that it is possible to discriminate anesthetic vapors from anesthetic gases and nonimmobilizers by comparing their dissolution dynamics. The nonimmobilizers have extremely low or no solubility in water and change the surface tension only negligibly. By use of newly defined molecular dissolution/diffusion coefficients, a simple model for the determination of partition coefficients is developed.
