The CaO2 nanoparticles show a very dark image of HR-TEM because CaO2 nanoparticles possess a higher electron density. The particles were shown as single and isolated because of presence of...

The high-resolution TEM (HRTEM) image in Figure 3A reveals that the 70-nm aggregates were comprised of numerous nanocrystals with sizes in the range of 5–10 nm. As shown in Figure 3B, the lattice spacing of an individual nanocrystal was measured to be 0.25 and 0.29 nm, respectively, which could be assigned to the (110) and (002) planes. This
