Droplet Surface Shows 2D State (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption Nanocrystals within a liquid droplet that is injected into an oily solution (left) are chemically compressed into a solid-like "jammed" 2D state (middle) -- which causes wrinkles to form on the surface of the droplet -- and then revert to a relaxed, liquid-like state (right) in which the wrinkles smooth out.
