Discover the science behind diodes — the tiny components that control the flow of electricity. Learn how they let current pass in one direction, block it in the other, and power everything from phone ...

A weird phenomenon in which electricity flows like water was spotted in a nanowire made of "strange metal" — a bizarre metal phase that has stumped physicists for 40 years. When you purchase through ...

After a year of trial and error, Liyang Chen had managed to whittle down a metallic wire into a microscopic strand half the width of an E.coli bacterium — just thin enough to allow a trickle of ...

Over the millennia, the phenomenon known as electricity has meant different things to different people. In ancient societies, electricity—or more specifically lightning—was inspiration for some of the ...

Inside every living cell, tiny molecular machines are constantly in motion, shifting shapes, tugging on membranes and shuttling ions from one side to the other. That restless activity does more than ...

Coulomb blockade is a phenomenon in which the flow of electrons through a nanostructure, such as a quantum dot or a single-electron transistor, is restricted due to the electrostatic repulsion between ...

Which way does electricity flow through a vehicle’s electrical system? From positive to negative, or from negative to positive? Depending on your viewpoint, it can flow either way. When most people ...
