High-resolution scanning and transmission electron microscopy (S)TEM analysis. Low-magnification (a) and high-magnification (b) TEM images of the Ca-MDP nanolayers observed at low doses clearly show the Ca-MDP nanolayers in their characteristic highly layer-ordered profile. No Ca2+ atomic ordering could be observed. (c) HAADF-STEM image at low magnification where periodicity measurements show regional distancing variations at locations of (i) ~ 4.2 nm and (ii) ~3.8 nm. (d) High-resolution HAADF-STEM image showing the nanolayering stack (white arrows); with the inset of the FFT in (e) shows an average interplanar space of 3.5 nm. (f) High-magnification HAADF-STEM image of a single Ca-MDP nanolayer with no Ca2+ atomic ordering could be observed.
