New testing method can predict cracks before they appear

A new method for testing fatigue in metals at a microscopic scale can predict when early, localized damage will evolve into cracks.

Graphene comes together to exhibit highly correlated electron properties

Twisted stacks of bilayer graphene can exhibit highly correlated electron properties, which likely relates to the emergence of exotic magnetic states.

Simple twist unlocks magnetism in graphene

Researchers have discovered a variety of exotic electronic states, including a rare form of magnetism, in a twisted three-layer graphene structure.

Strain forces diamond needles to alter their electronic properties

Applying strain to tiny needles of diamond can transform their electronic properties from insulating, through semiconducting, to highly conductive.

Study uncovers dislocation pathways to advanced alloys

Using experiments and simulations, researchers have identified the configurations of dislocations that give rise to desirable properties in a model alloy.
