Shini explores electric current, voltaic cells, and how we get electric charge. Electric current works like a river... kinda... Instead of flowing based on elevation ...

Quantum metals are metals where quantum effects—behaviors that normally only matter at atomic scales—become powerful enough ...

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 ...

Electric current comes in many forms: current in a wire, flow of ions between the plates of a battery and between plates during electrolysis, as arcs, sparks, and so on. However, here on Hackaday we ...

Large-scale currents are the conveyor belts of the ocean, transporting water and nutrients and controlling Earth's climate.

Physicists from Trinity College Dublin and the Universidad Complutense of Madrid have made a peculiar discovery in which energy moves from a colder to a hotter region. They describe how a quantum ...

In school, you might have learned that electrons were negatively charged and protons were positive. This is not a fact of nature but a human-invented convention. It’s a fact that protons and electrons ...

Researchers explain why weak magnetic fields can instantly control electrical flow direction in these quantum metals. (Nanowerk News) Quantum metals are metals where quantum effects—behaviors that ...
