Anion exchange membrane water electrolysis (AEMWE) is a promising technology for sustainable hydrogen production, combining the prospect of high current-density operation with the potential for reduced reliance on scarce materials. This thesis investigates the integration of nickel–iron layered double hydroxide (Ni3Fe-LDH) as an oxygen evolution reaction (OER) catalyst into AEMWE systems, with the goal of developing and validating membrane electrode assemblies (MEAs) suitable for scalable fabrication and future stack integration.

During operation of high-power nuclear fusion reactors plasma-facing components (PFCs) are exposed to challenging conditions. Due to its properties, pure tungsten is currently the preferred candidate for the plasma-facing material (PFM). [...]

The interplay between exchange interaction and spin-orbit coupling (SOC) in lowdimensional ferromagnetic systems plays a pivotal role in shaping their electronic and spin properties, with direct implications for spintronic applications. This thesisinvestigates the electronic structure of ultrathin epitaxial FePd alloy on Pd(001) using spin- and momentum-resolving photoemission spectroscopy, focusing on symmetry breaking and SOC-driven band hybridization.
