Screw dislocations play an important role in materials’ mechanical, electrical and optical properties. However, imaging the atomic displacements in screw dislocations remains challenging.

Finding new alloys just became simpler Date: September 16, 2021 Source: University of Groningen Summary: In metal alloys, behavior at the atomic scale affects the material's properties.
