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 ...

Nanostructured metals often exhibit superior mechanical properties due to strong size effects at the nanoscale 1,2. They have been used as important components for modern nanotechnology and ...

Movement of a dislocation becomes more difficult if some barrier or discontinuity enters the path of the dislocation, that is, the materials are hardened. Among many hardening routines, precipitate ...

Observation of dynamic processes by transmission electron microscopy (TEM) is an attractive technique to experimentally analyze materials’ nanoscale phenomena and understand the ...

Engineers devised a new method for designing metals and alloys that can withstand extreme impacts, which could lead to the development of automobiles, aircraft and armor that can better endure ...
