ingenierilupon heating the surface to 200 °c the molecules move forward and back as they roll on their fullerene wheels. the nanocar is able to roll about because the fullerene wheel is fitted to the alkyne axle through a carbon-carbon single bond. the hydrogen on the neighboring carbon is not great obstacle to free rotation. when the temperature is high enough, the four carbon-carbon bonds rotate and the car rolls about. occasionally the direction of movement changes as the molecule pivots. the rolling action was confirmed by professor kevin kelly, also at rice, by pulling the molecule with the tip of the stm.
