We are pleased to announce exciting news from our research group:

Subin Lee successfully obtained funding through the Helmholtz Imaging Projects for his project in the field of imaging and data science. This collaborative initiative, led by two experts from the KIT (IAM-MMI) and Forschungszentrum Jülich (FZJ, IAS-9), namely Prof. Christoph Kirchlechner, and Prof. Stefan Sandfeld, aims to advance our comprehension of the degradation mechanisms affecting functional materials. This will be achieved by integrating advanced electron microscope imaging techniques with deep learning (DL).

The primary focus of the project is to understand the behavior of dislocations, which play a critical role in the degradation of functional materials exposed to mechanical stress. While traditional transmission electron microscopy (TEM) provides invaluable data, it is limited by sample size and in-situ testing capabilities. On the other hand, scanning electron microscopy (SEM) offers a larger specimen chamber and more flexibilities for in situ facilities, however encounters challenges when it comes to effectively capturing dislocations and deformation mechanisms at the micro-/nano-scale.

To overcome these obstacles, our team will develop in situ 4D-STEM-in-SEM imaging, taking full advantage of advanced DL techniques such as feature detection and adaptive scanning. With successful outcomes, we envision the potential expansion of this project into various research domains, encompassing the exploration of degradation mechanisms in the field of energy materials and beyond.
