Scale-bridging tomography and in situ microscopy of SCALMS (A03)

• Subject Area: Synthesis and Properties of Functional Materials
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 431791331

Project A03 addresses the temperature-dependent phase stability of SCALMS, the liquid alloy distribution, the surface composition, and the wetting behaviour in porous support materials. For this purpose, we will use analytical and in situ transmission electron microscopy (TEM) as well as scale-bridging tomography techniques, ranging from atom probe tomography (APT) and electron tomography (ET) to X-ray nanotomography (NanoCT). The project includes in situ studies with high spatial resolution of model nanoalloys at near operation conditions, three-dimensional chemical and structural analysis of SCALMS with high-resolution through correlative TEM/APT, and scale-bridging correlative 3D analysis of SCALMS after catalytic operation.
