Analytical transmission electron microscopy (TEM) has become a widely
implemented technique in a modern catalysis research institute. TEM is a
key technique for the investigation of local elemental compositions,
surfaces and atomic interfaces, which are crucial for catalytic
performance. However, usually TEM specialists perform the necessary
tasks for a thorough study of the materials of interest. The ChemiTEM
project aims to generate standard procedures and workflows optimized for
non-expert TEM users for applications in material synthesis and
chemistry. By investigating 40 samples of the Fritz-Haber-Institut and
its collaboration partners we collected the relevant questions and
developed standardized workflows and guiding tools for sample
preparation and investigation. These workflows were implemented into a
tablet app enabling non-expert TEM users to perform even applications
they have no previous experience with by guiding them through the whole
decision process. The app also includes a workflow for data analysis. I
will present the current status of the ChemiTEM project, its future
developments, and other related research of our group at MPI-CEC.
