In this work, we present a number of techniques to improve the quality of the acquired nanotomography data, together with easy-to-implement methods to obtain “advanced” microstructural quantifications. The techniques are applied to a solid oxide fuel cell cathode of interest to the electrochemistry community, but the methodologies are easily adaptable to a wide range of material systems.

In this work, we demonstrate a simple spin-coating system that can be used to easily coat planar samples with a conductive polymer film. Such a system provides protection to samples during FIB imaging and milling at a fraction of the cost of traditional coating instruments.

In this work, we characterize the transition layer at the 4H-SiC/SiO2 interface as a function of nitric oxide (NO) post-annealing time using HRTEM and EELS. We confirm an inverse relationship between NO-anneal time and transition layer width, which correlates with improved channel mobility.
