Nice!, but you should also really try to make copper-oxide-ish-stuff with electrolysis. Just use two copper pieces in a solution of kitchen salt (NaCl and amount does not matter) put 5V or ...

Diode-based power sensors extend the power measurement range far below 300 nW. They offer a dynamic range of up to 90 dB. Depending on their implementation, these sensors can also measure the power ...

The higher the frequency the harder to get a decent tube, so certainly for 432MHz and up, most converters had the antenna feeding a diode mixer. Not good, but better than a tube rf stage.

A team at MIT is working on constructing thermal diodes that are able to convert heat to electricity at lower temperatures than ever before, which may eventually lead to practical uses for thermal ...

To make a diode that could produce visible light, scientists had to widen the energy gap. By the early 1970s, scientists had discovered how to make bright red, yellow, ...

It may also be possible to make the diode operate as an LED. “My results are not only a direct confirmation of the structural purity of single-walled nanotubes but a strong affirmation of their ...
