A bit of old-fashioned oscillation: The attraction of contact charge electrophoresis

Date: Apr 21, 2015

Author: Jon Evans

When looking for a new way to convert chemical and electrical energy into motion at small scales, US chemical engineers were inspired by a technology over 250 years old to develop a new form of electrophoresis.
