Spin Me Right Round
July 11, 2003 | Source: ScienceNOW
Tiny rotary motors made of spinning molecules hold the promise of driving microscopic devices of the future. But so far, scientists have had a difficult time controlling which direction tiny artificial cogs spin. New interlocking rings designed by a team of researchers may solve that problem, bringing the vision of clockwork machinery on a molecular scale one step closer to reality.
UV laser bursts could easily make the rings spin at millions or billions of revolutions per minute if needed.
