Ultrasonically propelled nanorods spin dizzyingly fast

22 julio 2014

Vibrate a solution of rod-shaped metal nanoparticles in water with ultrasound and they’ll spin around their long axes like tiny drill bits. Why? No one yet knows exactly. But researchers have clocked their speed — and it’s fast. At up to 150,000 revolutions per minute, ten times faster than any nanorotor ever reported.
