Japanese researchers have revealed how weak magnetic fields can instantly control the direction of electrical flow in quantum metals. Quantum metals are materials in which quantum effects, usually ...

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

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 ...

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 ...

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 ...
