Description
Presumably simple solutions can show a variety of nanoscale aggregation structures. Ternary mixtures of three liquids, in which two show only partial mutual solubility, resemble different types of microemulsions even in the absence of classical surfactants. We present fully atomistic molecular dynamics simulations of octanol/ethanol/water mixtures, a typical representative of these “surfactant-free microemulsions”. We compare MD simulations results with different scattering experiments: SAXS/WAXS and neutron scattering reveal the structures present. Neutron Spin-Echo and NMR experiments gives insight into their dynamic behaviour.
