A 3D-printed material that glows when a force is applied to it could be used to better understand how objects break.
at the Kunming University of Science and Technology in China and his colleagues have created a material that glows where a force pushes on it.
Similar materials have been made before from compounds called lanthanides, which contain rare-earth elements like lutetium, but they are normally thin and flat. The researchers wanted to make a material thick enough so it would show how…
