his dissertation aims to fill the gap in experimental evidence by first investigatingthe influence of material properties and He plasma parameters on the He-W inter-action broadly and then isolating a parameter variations directly linked to the Heinteraction mechanisms of interest.For this, recrystallised polycrystalline tungsten (polycrystalline tungsten (poly-W)) samples, undamaged and irradiation-damaged to varying doses, were first usedin several exposure series screening the influence of He flux, fluence, energy, andpre-existing defects. To optimise the surface preparation for single-crystalline tung-sten (single-crystalline tungsten (sc-W)), open-volume defect concentrations in thenear-surface region of the samples were characterised by Doppler-broadening spec-troscopy of the positron annihilation line (Doppler-broadening spectroscopy of thepositron-electron annihilation line (DBS)).

A promising antibacterial strategy relies on surfaces that combine contact-killing activity with controlled release, enabling rapid response and long-term reusability. Herein, we report such kill-and-release antibacterial surfaces based on lamellar-organized amphiphilic diblock copolymer thin films. [...]

Magnetic skyrmions are spin textures with nontrivial topology that form two-dimensional hexagonal lattices (SkX) in chiral magnets. Element-specific reciprocal-space characterization of skyrmion lattices with soft x-rays commonly relies on transmission geometries, which require thinning of bulk crystals and can modify their magnetic properties.
