Tuesday publication update! 📖 This published research from the Karlsruhe Institute of Technology focuses on novel technique for local hydrogen concentration detection in metals.The AtmosphereAX system was used to do in situ gas phase scanning transmission electron microscopy (STEM).
🔬Measured hydrogen concentration in cubic palladium nanoparticles (Pd NPs) with a lateral resolution of 4 nm using STEM and energy electron loss spectroscopy (EELS).
📺It was possible to do real-time tracking of hydrogenation and dehydrogenation processes by analyzing the shift in the Pd bulk plasmon peak during in situ TEM experiments.
📈 The authors linked local hydrogen concentration with microstructure and strain, providing a comprehensive understanding of material behavior during hydrogen interactions.
✨This method enables a deeper understanding of hydrogen-related phenomena such as storage, detection, catalysis, and embrittlement, offering a powerful tool for optimizing materials in hydrogen technology.
Congratulations to Svetlana Korneychuk, Stefan Wagner, Darius Rohleder, Philipp Vana, and Astrid Pundt for this great publication!
