Atom Probe Tomography

We have some very good news to share: Dr. Baptiste Gault, head of our research group “Atom Probe Tomography”, was honoured this year with the Leibniz Award, the highest German research award. Dr. Gault is a worldwide leading scientist who pushes the technique of atom probe tomography (APT) to its limits. Already during his PhD studies, he implemented a pulsed-laser source on an atom probe, paving the way for the modern design of commercial APT instruments. He not only probes complex metallic materials at so far unprecedented resolution, but found a way to analyse with APT even biological materials, including proteins suspected to contribute to Alzheimer. His group works on connecting the vast amount of data from APT with machine learning techniques to accelerate and facilitate data extraction. And, one current big project, which is funded by the European Research Council, targets a crucial problem faced both by the steel industry and the hydrogen economy: the effect of hydrogen on metallic alloys. But, let him speak by himself in this very special newsletter edition.

Hi, I’m Baptiste. I lead two research groups at the Max-Planck-Institut für Eisenforschung (MPIE). I was invited to guest edit this newsletter because I was awarded the Leibniz Prize 2020 by the German Research Foundation. The Prize was awarded to me for my frontier work in atom probe tomography (APT) and the research that the technique enables. [more]
In 1814, Pierre-Simon Laplace postulated that if at any moment a “demon” could know the position and momentum of each and every one of the atoms in the universe, it would know everything about their past and their future. Inspired by this idea, we started putting together infrastructure enabling the correlation of multiple microscopy techniques on the same specimen. [more]
