Blocking infinity in a topological insulator

(Phys.org)—In bulk, topological insulators (TIs) are good insulators, but on their surface they act as metals, with a twist: the spin and direction of electrons moving across the surface of a TI are locked together. TIs ...

Graphene researchers make a layer cake with atomic precision

Graphene and associated one-atom-thick crystals offer the possibility of a vast range of new materials and devices by stacking individual atomic layers on top of each other, new research from the University of Manchester ...

New circuit breakers prevent electrical fires

A new fire protection circuit breaker from Siemens prevents electrical fires from developing. The device registers dangerous arcing in an electrical installation and breaks the circuit automatically. Arcing can happen as ...
