unwetting
 n.— «He cited the process called “unwetting,” describing it is the way water seems to be repelled or expelled from the surfaces of certain materials. When grapes were sprayed with a fungicide mist, he said, the liquid did not cover the grape, but formed a single droplet at the grape’s base. “Our research, which initially was strictly fundamental,” he said, made it possible to create sprays that covered 10 times as much of the surface of the grape.» —“LCD and Wine Researcher Pierre-Gilles de Gennes” by Martin Weil Washington Post May 22, 2007.
