  In a comprehensive study on several samples we demonstrate for our
laboratory-based computed tomography system resolutions down to 150nm. The
achieved resolution is validated by imaging com-mon test structures in 2D and
Fourier Shell Correlation of 3D volumes. As representative application examples
from nowadays material research, we show metallization processes in multilayer
integrated circuits, ageing in lithium battery electrodes, and volumetric of
metallic sub-micrometer fillers of com-posites. Thus, our laboratory system
provides the unique possibility to image non-destructively struc-tures in the
range of hundred nanometers, even for high density materials.
