Researchers show how to control liquid crystal patterns (Image 2)

Researchers at the University of Pennsylvania confined liquid crystals within droplets, creating shells floating in water. To create patterns, they then added surfactants to the water. Because liquid crystals are similar to oil, the surfactants were attracted to the liquid crystal shells, causing ...This is an NSF Multimedia Gallery item.
