“…This is not always the case for competitive adsorption between different surfactants, and situations arise where either a positive or a negative synergy exists. This is in contrast, for example, to the situation for SDS/dodecanol (11) and C 16 TAB/dodecane (13), where the total adsorption for the mixture is greater than the adsorption for the individual components.…”

“…By deuterium labeling each component in turn the adsorbed amount of that component can be determined, whereas measurement with both components labeled gives an estimate of the total adsorption. This approach has been successfully applied to a range of different surfactant mixtures (5)(6)(7)(8)(9)(10)(11)(12)(13).…”

“…We have previously shown that specular neutron reflection, in combination with D/H isotopic substitution, is a powerful technique for the study of the composition and structure of mixed surfactant monolayers adsorbed at the air-water interface and other interfaces (5)(6)(7)(8)(9)(10)(11)(12)(13). This has now been extensively demonstrated on a range of different mixed surfactant systems (5)(6)(7)(8)(9)(10)(11), in surfactant/alcohol mixtures (12) and surfactant/alkane mixtures (13).…”

“…the dependencies on the extent of adsorption and the hydrophobic chain length of the surfactant) are also exhibited by the adsorption and penetration of oil molecules from the vapour phase into surfactant monolayers at the air-water surface. [29][30][31][32][33][34][35][36][37][38] In addition to the surfactant studies described above, the optical response triggered by surface anchoring changes of LC systems has been used to investigate many different surface processes. These include the patterning of solid surfaces, [1,4,6,9,14,23,24] surface re-organisation of adsorbed phospholipids, [12,20] protein and ligand binding, [2,5,8,10,16,17,18,22,21] bound virus imaging, [15] chemical [3] and enzyme catalysed reactions, [13] the pH response of adsorbed polymers, [26] layer-by-layer polymer film assembly [25] and DNA hybridisation.…”

UV Polymerisation of Surfactants Adsorbed at the Nematic Liquid Crystal–Water Interface Produces an Optical Response

We have investigated the changes in crossed polariser optical textures produced by adsorption and UV polymerisation of a range of polymerisable surfactants at the interface between a nematic liquid crystal and water. Similar to non-polymerisable surfactants, the adsorption of polymerisable surfactants with sufficiently long hydrophobic tail groups produces a transition from planar to homeotropic anchoring. UV polymerisation of surfactants with a polymerisable group located in the hydrophobic tail region changes the anchoring from homeotropic back to planar. Polymerisation in the hydrophilic headgroup region does not produce an optical transition. We demonstrate that these systems can be used to "write with light" in the interfaces and that they form the basis of a UV sensor device in which the optical response is visible to the naked eye.

The surface tension of aqueous solution drops of ß-casein, ß-lactoglobulin, and human serum albumin at the interface to air and hexane saturated air are measured by drop profile analysis tensiometry. The results indicate that the dynamic and equilibrium surface tension for a hexane vapor atmosphere are considerably lower as compared to the values at the interface with pure air. The experiments are performed with the initial adsorption of protein followed by hexane adsorption, and with subsequent removal of hexane from the measuring cell after equilibrium is attained. Two models are proposed, both of which assume the diffusion of protein in the solution and either diffusion-governed or barrier-governed hexane coadsorption. The new developed theoretical equilibrium model assumes a double layer adsorption in these systems, with the first layer composed of protein mixed with hexane and the second layer formed by hexane molecules only. The experimental and calculated equilibrium surface tension data are in a perfect agreement. Note the model parameters are exactly the same as those found for the individual compounds
