Synergistic effects in self assembly induced structuring of the water-air interface
The hypothesis is that inducing packing constraints in the self assembly structure of fatty acids at the water-air interface can cause the liquid-air interface to dimple in a 3D fashion. This was spectacularly proven for the first time using FIGARO 2 days before this proposal deadline. The branched fatty acids in question are biologically interesting due to their barrier properties on hair and wool. These experiments may also cast light on their biological function, and possibly their bacteriostatic properties. The recent measurements showed an unexpected but unmistakable synergy effect in the extent of interfacial dimpling. To allow this effect to be understood and permit publication of this extremely important observation, we are applying for beam time to study the interfacial dimpling of mixtures of three different combinations of fatty acids. With the combination of fatty acids proposed and their different individual dimpling properties, a sufficiently large matrix will be generated to explain the mechanism of this striking synergistic effect.
