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 ...

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 creep is a deformation mechanism transporting shear through the crystal lattice by the motion of line defects, called dislocations. This mechanism involves the elementary processes of ...

Material structures are rarely perfect, but researchers at the Japan Advanced Institute of Science and Technology (JAIST) have now identified a way to make them more so. By monitoring in real time how ...

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 ...
