Atom Probe Tomography

Caption

Arun Devaraj, a staff scientist at PNNL, loads a sample into a chamber in preparation for an atom probe tomography experiment. This method, which can provide a nanoscale 3-D map of a chemical element's distribution in a material, was used in combination with other techniques, including X-ray experiments at Berkeley Lab, to study a type of catalyst known as a zeolite.
