In their paper published in the journal Science, the group describes how experiments led to the discovery of a way to get some fluids to remain as an emulsion for long periods of time without the use of surfactants. It is widely known that when two immiscible liquids, such as water and oil, do not remain so for very long—they slowly separate into two layers. This is because they never really mix to begin with; instead, they coexist as droplets that coalesce when they come into
