How to Transmit Torque at the Nanoscale (image) University of Bristol Share Print E-Mail Caption A model microscopic system to demonstrate the transmission of torque in the presence of thermal fluctuations -- necessary for the creation of a tiny 'clutch' operating at the nanoscale -- has been assembled at the University of Bristol, UK. This image shows the principle of operation of the 'nanoclutch': red spheres rotate clockwise and an opposing torque is applied to a central axle.
