A diode allows current to travel in only one direction. With that in mind, [Alex] built a mechanical diode that will only allow gear rotation in one direction to be transmitted through the system. But ...

(Nanowerk News) Transistors, resistors, capacitors, and diodes. All of these are examples of common electrical circuit elements that can be found on a computer motherboard, for instance. Billions of ...

An optical diode made with silicon technology can be used for quantum information. Researchers propose using ring resonators to construct a micro-optical diode. The technology is silicon-on-insulator, ...
