Single-molecule electric motor

The single-molecule electric motor is an electrically operated synthetic molecular motor made from a single butyl methyl sulphide molecule. The molecule is adsorbed onto a copper (111) single-crystal piece by chemisorption. The motor, the world's smallest electric motor, is just a nanometer across. It was developed by the Sykes group and scientists at the Tufts University School of Arts and Sciences and published online September 4, 2011.
