A nano two-wheeler
Abstract:
According to New Scientist, French and German researchers have built a nanoscale machine with two wheels of a diameter of 0.8 nanometers joined by an axle of only four carbon atoms long. It has been done before, but this time, the nanoscientists have been able to really watch these nano-wheels rolling and rotating over a flat surface. It has been claimed before, but it is the first time that researchers have directly seen this nanowheel rotation. And this discovery probably opens the way to future molecular machines.
