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 ...

A Prototype switch built in nanoscopic level can increase efficiency of electronics devices by reducing the heat it generates ...

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 ...

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 thermogalvanic device uses nanoparticles to control ion flow, allowing it to convert waste heat to electricity and store the energy without external batteries.

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 ...

When we eat, our cells break down sugars, while their excess electrons flow through a series of chemical reactions until they’re passed onto oxygen. This process generates the energy molecule ATP, ...

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 ...

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 ...
