Watching Rust Form at the Atomic Level

Wednesday, February 6, 2019

As published in the National Academy of Sciences, via Gizmodo: researchers at PNNL using Atom Probe Tomography make a breakthrough discovery.

"The researchers created microscopic rods out of goethite, a key mineral component of rust, and reacted them with water dissolved with iron atoms. Some of these dissolved iron atoms had an extra neutron in their nucleus, allowing the scientists to keep better track of how they attached to and entered the nanorods. Then, they imaged the reaction using atom-probe tomography, or APT, which can discern the individual atoms’ identity and positions."
