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, ...

We’re all familiar with semiconductor diodes, whose function is to allow electricity to easily flow in one direction and impede its progress in the other. A thermal diode performs a similar gating ...

Diodes allow electricity to flow in only one direction, protecting and controlling circuits. This video explains how they ...

A diode is an electric device which allows the flow of current only in one direction and restricts the current flow in the opposite direction. A diode starts its operations when a voltage signal is ...

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 have reviewed the superconducting diode effect, a quantum effect enabling dissipationless supercurrent to flow in only one direction. The SDE provides new functionalities for ...

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 ...

Researchers have created a diode out of a 1 nm-sized single molecule with high rectification ratios. Diodes, commonly used in in everyday electronic devices, allow current to flow in one direction ...

Scientists have shown that twisting a crystal at the nanoscale can turn it into a tiny, reversible diode, hinting at a new era of shape-engineered electronics.

New York, NY--May 25, 2015--Under the direction of Latha Venkataraman, associate professor of applied physics at Columbia Engineering, researchers have designed a new technique to create a ...
