At the nanoscale, what used to mix no longer does
.

In a silica nanotube of a few billionths of a metre (diameter) the alcohol/hydrocarbon mixture separates into a core-shell structure (hydrocarbon in the centre, alcohol on the outside). Physicists from Rennes have explained the phenomenon. They validated their hypothesis by reversing the separation structure (alcohol in the centre, hydrocarbon on the outside) by modifying the hydrophobic properties of the nanotube.
