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 ...

In graphene, electrons move in strange ways. Their unusual and fluid-like behavior was observed by scientists at the National Graphene Institute, leading to a new wave of studies related to the ...

Researchers have experimentally caused electrons to bend in bilayer graphene with the use of light. The way electrons flow in materials determine its electronic properties. For example, when a voltage ...

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 ...

Key learning points Electrical charges What are free electrons? Cell polarity Conventional current direction Electrons orbit the nucleus. An atom has a neutral charge, because it contains the same ...

A new type of switch sends electrons propagating in opposite directions along the same paths – without ever colliding with each other. The switch works by controlling the presence of so-called ...

(Nanowerk News) You don’t normally want to mix electricity and water, but electricity behaving like water has the potential to improve electronic devices. Recent work from the groups of engineer James ...

Photosynthetic reaction centres show promise for biomolecular electronics as nanoscale solar-powered batteries and molecular diodes that are amenable to atomic-level re-engineering. In this work the ...

If you want an electrical current to flow around a normal metal ring you have to supply enough energy to overcome the metal’s resistance – right? Not always, according to physicists in the US and ...

On a quest to discover new states of matter, a team of Princeton University scientists has found that electrons on the surface of specific materials act like miniature superheroes, relentlessly ...

RICHLAND, Wash. -- If the Flintstones had electricity, their wires might have been made of rock. New results in Science Express show that a chunk of hematite can conduct electrons under certain ...
