This group from the Helmholtz-Institute Erlangen-Nürnberg performed simulations, both on a coarse-grained and a molecular level of detail, elucidating how so-called antagonistic salts, consisting of a large anion and a small cation, trigger the spontaneous formation of highly regular, nanometer sized structures in water/oil mixtures. Due to their size difference the small cations accumulate in the water phase while the large anions go to the oil phase. The resulting electrostatic interactions between the phases can lead to long-range ordering.
