We identified heterogeneous Mg-Ho alloys as an ideal material to measure the most extensive acoustic emission spectra available. Mg-Ho alloys are porous and show a high density of dislocations, which ...
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 ...
Observation of dynamic processes by transmission electron microscopy (TEM) is an attractive technique to experimentally analyze materials’ nanoscale phenomena and understand the ...
As metal structures get smaller -- as their dimensions approach the micrometer scale or less -- they get stronger. Now scientists have learned how. The researchers observed that compressing nanoscale ...

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 ...
