A diode is an electrical device that allows current to move through it in one direction with far greater ease than in the other. The first diodes were crystals used as rectifiers in home radio kits. A ...

Scientists successfully control the direction of current in a superconductor, creating a superconducting diode. (Nanowerk News) What would happen if you combined the unparalleled efficiency of a ...

Engineers have long known how to steer electricity in one direction, but heat has been far harder to tame. Now a new one-way thermal “diode” promises to give designers similar control over heat flow, ...

The effective control of heat transfer is of great significance to improve energy efficiency. Thermal diode is one of the key elements for heat flow controlling. Similar to the current rectification ...

Forty years ago, scientists theorized that a single molecule could function as a diode—an electronic circuit element that allows current to flow in one direction but not the other. In the ongoing push ...
