Metal surface can repel electric charges

(Phys.org)—Metals are known for being good electrical conductors. Due to this property, a stationary electric point charge placed outside a metal will cause the electrons in the metal to redistribute in such a way that ...

Ray of light could lead to next generation of superconductors

A superconductor, which can move electrical energy with no wasteful resistance, is the holy grail of cost-effective, efficient, and "green" power production. Unlike traditional conductors such as copper or silver, which waste ...

'Nanocable' could be big boon for energy storage

Thanks to a little serendipity, researchers at Rice University have created a tiny coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors.
