The authors find that when a drop of water is placed in the hydrocarbon dodecane with phospholipids, emulsion droplets and multilamellar concentric structures called "onions" spontaneously form. A multilamellar film in a semicrystalline state forms at the interface between the dodecane and the water. As this film swells with water, it sheds the onions and emulsion droplets. The authors find that the core of the onions consists of dodecane, water, and lipids, while the shell is made of partially hydrated concentric bilayers.
