For a motor to power machinery, the local motion has to be translated into the ordered movement of other parts of the system. Organic chemists have now produced a light driven rotary motor in which ...

"Instantaneous peak Inrush current is a momentary current transient that occurs immediately (within half an AC cycle) after contact closure. Locked rotor current is the root-mean-square (RMS) current ...

This is University of Groningen professor of organic chemistry Ben Feringa. The naphthalene rotor is attached to the motor by a single carbon-carbon bond, which allows it to rotate freely. But the ...
