Inventing the Nanomolecular Wheel

  title={Inventing the Nanomolecular Wheel},
  author={Jay S Siegel},
The wheel is considered the canonical invention leading to all manner of mechanical devices. Rotating machinery is also being investigated at the nanoscale as researchers attempt to create molecular analogs of wheels and motors. But will these devices be merely imitations of macroscopic machines? In his Perspective, [Siegel][1] discusses results reported in the same issue by [ Fletcher et al. ][2] in which a four-stroke chemical nanoengine is reported. By a series of bond-breaking and bond… CONTINUE READING
