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 ...

An international team of researchers, led by University of Toronto Engineering Professor Yu Zou, is using electric fields to control the motion of material defects. This work has important ...

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 materials. So, as a ...

Researchers have discovered that engineering one-dimensional line defects into certain materials can increase their electrical performance. Materials engineers don't like to see line defects in ...
