Relax, just break it

Fri, 07/20/2018 - 11:07
The properties of a solid depend on the arrangement of its atoms, which form a periodic crystal structure. At the nanoscale, arrangements that break this periodic structure can drastically alter the behavior of the material, but this is difficult to measure. Recent advances by scientists are starting to unravel this mystery.
