Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. These linear defects, or dislocations, are what ...

Dislocation dynamics examines the behaviour of line defects within crystalline materials—imperfections that are central to understanding plastic deformation. At the microstructural level, the motion ...

Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications.

AMES, Iowa – Materials engineers don’t like to see line defects in functional materials. The structural flaws along a one-dimensional line of atoms generally degrades performance of electrical ...

Quantum engineers have spent years trying to tame the fragility of qubits, only to be thwarted by the tiniest imperfections in the materials they use. Now a new line of research flips that problem on ...
