We have developed an in-situ reaction chamber for atom probe tomography (APT) to experimentally measure in-situ gas-surface reactions as a function of time, temperature, and pressure [1]. We are able to look at a very broad range of gases and reactions and the ability to perform these measurements allows us to accurately perform calculations for a wider range of environments and providing a wider range of values for calibrating atom probe reconstructions and subsequent electronic structure modeling [2]. Therefore, combining this in situ atomistic measurement capability for surface reactions with computational protocols allows us to computationally address the issues related with surface degradation under extreme environments.
