Mapping the way for cobalt catalysis The cover picture shows a typical 3D montage of the analytical 3D model of a selected supported cobalt grain obtained by using energy filtered (EFTEM) tomographic analysis applied to Si, Ti, and Co elements. In their Full Paper on p. 2610 ff., O. Ersen, C. Pham-Huu et al. present a detailed analysis of their Co/TiO2-SiC catalyst by 2D and 3D chemical imaging, based on EFTEM, combined with the more traditional high-resolution TEM mode. The study allowed them to precisely solve the microstructure, the porous characteristics, and the distribution of the constituting phases.
