New rotors could help develop nanoscale generators

Posted on 27. May, 2009 by admin.

In collaboration with the Chinese Academy of Sciences in Beijing, scientists have investigated the rotation of molecules on a fixed surface to understand how they may help in the development of future rotor-based machinery at nanoscale level.
The research focused on rotating magnetic fields, which play an important part in machines like electric motors and generators. [...]

With a single electron pump, PTB researchers provide ‘counted’ electrons with the desired spin
Many hopes are pinned on spintronics. In the future it could replace electronics, which in the race to produce increasingly rapid computer components, must at sometime reach its limits. Different from electronics, where whole electrons are moved (the digital “one” means “an [...]
