In solar cells, solar radiation boosts electrons to higher energy states, thereby releasing them from their atomic bonds as electricity begins to flow. Scientists have now developed a novel method to ...

A memory effect that is crucial in electronics has been seen for the first time in a cloud of ultracold atoms. The phenomenon represents a milestone in the emerging field of ‘atomtronics’, which seeks ...

HANOVER, N.H. – April 19, 2022 – Researchers at Dartmouth have built the world’s first superfluid circuit that uses pairs of ultracold electron-like atoms, according to a study published in Physical ...

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

Time to retire the old soldering iron? In the “atomtronic” circuits pictured on the right, it is atoms, not electrons, that flow. Such circuits could form the basis for ultra-sensitive gyroscopes.

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 ...

Your 14-year-old kids have probably spent as much of their summer holidays on their phones or computers as they have at the beach or moaning about how bored they are. Yet when they learn about ...
