Atomically packed boundaries resist cracking

Researchers used high energy X-rays to image the crack and also the grains inside a material in terms of size, shape, and position. Importantly, the new advances also determine the crystallographic orientation of the atomic arrangements in each grain.

Theory reveals the nature of crystals defects (of silicon carbide)

Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications. Using silicon carbide as an example, physicists have shown that even such computationally demanding defects can be successfully examined with atomic accuracy by means of a cleverly constructed, small in size, model.

End-run spreads lithium throughout battery electrodes

Scientists used chemical valence sensitive X-ray microscopy to measure the movement of lithium and the rate of phase separation in thousands of battery nanoparticles, in place and under operation, while in the battery chemical environment.
