Water compresses under a high gradient electric field

(University of Illinois College of Engineering) Scientists at the University of Illinois at Urbana-Champaign have predicted new physics governing compression of water under a high-gradient electric field. Physics Professor Aleksei Aksimentiev and his post doctoral researcher James Wilson found that a high electric field applied to a tiny hole in a graphene membrane would compress the water molecules travelling through the pore by 3 percent. The predicted water compression may eventually prove useful in high-precision filtering of biomolecules for biomedical research.
