Fig. 1: SEM and TEM images of CoO assemblies at the end of the reaction.
From: X-ray studies bridge the molecular and macro length scales during the emergence of CoO assemblies
Different magnifications highlight their hierarchical structure. a Probe-corrected SEM image of spherical assemblies built of irregularly shaped crystallites. b TEM image of assemblies grown after 90 min of reaction time. c HR-TEM image and the corresponding Fourier transformation (FT) (inset) reveal that an assembly exhibits different crystallite orientations. A dislocation in the (\(\overline{1}11\)) plane is marked with a white T. d Filtered image of c by inverse FT of the frequency components highlighted by circles in c selectively showing the (111) orientation in violet and the (200) orientation in blue. e HR-TEM image of a different assembly and its corresponding FT, and f filtered inverse FT of e highlighting only the (111) orientation. Individual crystallites do not align to each other in a common crystallographic orientation.
