Understanding how dislocations (line defects in the crystal structure) occur when 3D-printing metals has been unclear to materials scientists. Understanding when and how dislocations form in ...

Materials can deform plastically by atomic-scale line defects called dislocations. Many technical applications are based on this fundamental process, such as forging, but we also rely on the power of ...

Illustration of an intense laser pulse hitting a diamond crystal from top right, driving elastic and plastic waves (curved lines) through the material. The laser pulse creates linear defects, known as ...

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.

Background Shoulder dislocation is a common sporting injury. Glenoid deficiency is thought to be a risk factor for recurrent shoulder dislocations. This study was performed to assess the role of CT ...

For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, ...

(Nanowerk News) An international team of researchers, led by Professor Yu Zou (MSE), is using electric fields to control the motion of material defects. This work has important implications for ...

A promising semiconductor material, halide perovskite, could be improved if flaws previously thought irrelevant to performance are reduced, according to new research. A promising semiconductor ...
