AET has previously been used to image 3D crystal defects (such as dislocations, stacking faults, grain boundaries, chemical order/disorder and point defects) in materials at the single-atom level.

nearly perfect cube of silver onto a hard target turns its single-crystal microstructure into a gradient-nano-grained (GNG) structure. Scientists at Rice University are smashing metallic micro ...

Here we discover that mechanical deformations provide a route to switching thermodynamic stability between a semiconducting and a metallic crystal structure in these monolayer materials.

High-pressure research can be used to probe structure on an atomic level ... often have weaknesses at the boundaries between crystal grains. Metallic glasses lack these defects, which makes ...

Unfortunately, typical metallic luster materials cause environmental ... The team attributed this to the unique crystal structure of DS-DA1 with two coexisting assembled states, revealing that ...

A new study by Professor Tao Sun tracks the evolution of crystallographic defects in real time during metal additive manufacturing.
