Atom probe tomography (APT) provides 3D compositional mapping with atomic resolution for most elements, from light hydrogen to heavy uranium isotopes.  In this talk, I will introduce the working principle of APT and how it has been applied to answer long-standing questions in structural materials.  By combing with advances in other microscopy techniques, such as the cryogenic focused-ion beam, APT brings new opportunities for addressing challenges in hydrogen storage, lithium battery, and even bio-organic materials.
