New metrological technique uses stress for nanotomography

Researchers from the Skolkovo Institute of Science and Technology (Skoltech) and their colleagues in Russia and Spain demonstrated proof-of-concept of a new radiation-safe method for mapping the internal structure and stress distribution in samples of materials at the nanoscale, with a resolution about 100 times higher than that of the x-ray and neutron tomography techniques currently available.

White iron rust material provides safe UV protection

A research team consisting of National Institute for Materials Science (NIMS), Hokkaido University, and Hiroshima University has developed an iron oxide-based ultraviolet (UV)-absorbing powder material by stabilizing normally unstable, colorless, UV-absorbing di-nuclear iron species in porous silica.
