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 a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

In this article, we will explore the basic functions of the Zener Diode. This device resembles a compact cylinder, much like the conventional diode, with two terminals at the ends that can be wired or ...

PROVIDENCE, R.I. [Brown University] — Superconductors — materials that conduct electricity with zero loss of energy — have been well-understood since the development of what’s called the BCS theory in ...
