    Towards FIB-SEM Based Simulation of Pore-Scale Diffusion in SCR Catalyst Layers

    The diffusivity in the upper Cu-Chabazite layer of a dual layer ammonia oxidation catalyst with a lower Pt layer was investigated. In a first step, the pore structure of the upper Cu-Chabazite catalyst layer w...

    Early deformation mechanisms in the shear affected region underneath a copper sliding contact

    Dislocation mediated plastic deformation decisively influences the friction coefficient and the microstructural changes at many metal sliding interfaces during tribological loading. This work explores the init...
