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, ...

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 ...

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 ...

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 ...

How a Virginia Tech research team constructed its novel thermal diode. Test results of the thermal diode. Electrical engineers are obviously very familiar and comfortable with the basic diode, a ...

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 ...

Although they are a simple device, diodes do have a number of traits to consider. These traits are often application dependent. Some applications include: rectifiers, signal ORing, transistor turn off ...
