Quantum dot coupling is to restrict number of states and increase efficiency. Columb coupling is to avoid the blackbody limit. The current quantum-mechanical resonant-coupling model confirms the ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 109, No. 31 (July 31, 2012), pp. 12393-12397 (5 pages) Scalar couplings between covalently bound nuclear spins are ...

In this paper, the authors present the concept of transmitting power without using wires i.e. transmitting power as magnetic waves from one place to another is in order to reduce the transmission and ...

Couplings are probably the most compliant and predictable component in a motion system. Turn up the speed, however, and it's a different story. Learn how to address this engineering issue. Couplings ...

In controlled experiments, engineers have shown that electricity can be transmitted through the air using highly controlled ...

Torque spikes can melt elastomers and damage couplings. Learn how to prevent it. Torsional vibration is an occurrence that can have a negative effect on coupling elastomer elements. It can also have a ...
