TEM and EDX investigation of chosen CoFe2O4 samples. HR-TEM micrographs (a,d), EDX elemental mappings (b,e) and size histograms (c,f) of the CoFe2O4 educt on the left (a to c) and the sample after tenth PLFL passage on the right (d to f). The inlet of HR-TEM micrograph of the product (d) shows a conglomerate of particles of the by number dominant size fraction.
