9. Workflow and practical guidance for identical location scanning electron microscopy: reliable tracking of localized transformationsBlaž Tomc, Marjan Bele, Ana Rebeka Kamšek, Milena Martins, Aleš Marsel, Miha Hotko, Stefan Popović, Gregor Kapun, Črtomir Donik, Mitja Kostelec, Matjaž Godec, Nejc Hodnik, Luka Suhadolnik, 2025, original scientific article Abstract: Understanding material transformations at the nano- and microscale is essential for advancing electrocatalysis, energy storage, and other applications. Conventional SEM imaging, which captures random locations before and after treatment, struggles to distinguish real transformations from inherent sample heterogeneity. Identical Location SEM (IL-SEM) overcomes this by enabling re-imaging of the exact same region, offering clear evidence of localized changes in morphology, structure, and composition. Despite its simplicity and wide applicability, IL-SEM remains underutilized. This article presents a detailed, practical guide to implementing IL-SEM reliably, including sample alignment, multiscale imaging, and consistent re-localization. Key methodological tips and solutions to common challenges are provided, making the approach accessible even for non-expert users. To showcase its versatility, we present case studies involving electrocatalysts, alloys, and nanostructured materials. Moreover, by integrating IL-SEM with energy-dispersive spectroscopy (EDS) and electron backscatter diffraction (EBSD), we demonstrate how compositional and crystallographic evolution can be tracked alongside morphological changes. This optimized workflow offers a powerful, non-destructive method for visualizing dynamic material behavior and provides a foundation for IL-SEM to become a standard technique for studying structural evolution across diverse materials research fields.

10. Grain-resolved mapping of oxygen evolution activation on a Ni-superalloyČrtomir Donik, Luka Suhadolnik, Blaž Tomc, Anton Voronkin, Jon Ustarroz, Marjan Bele, Matjaž Godec, Nejc Hodnik, 2025, original scientific article Abstract: We report the first grain-resolved mapping of oxygen evolution reaction (OER) activation on a Ni-based superalloy using identicallocation EBSD, complemented by IL-SEM, IL-EDS, and SECCM. NiFe (oxy)hydroxide film formation and OER activity are strongly influenced by grain size and orientation, with (111)-oriented and smaller grains showing the highest activity. These findings reveal pronounced microstructure heterogeneity and establish IL-EBSD as a powerful tool for guiding the design of advanced electrocatalysts.
