Characterization of the CeO2 nanoparticles. a SMPS results for number size distribution for CeO2 nanoparticles in the aged 2 experiment at 60, 120, and 180 min after the start of exposure. The average number size distribution for the 240-minute duration of the exposure study is presented in the panel and in the inset (log scale) where the error bars represent one standard deviation of the number size distribution for each particle size bin. b XRD spectra presented as a function of the XRD scattering angle 2θ of the powder sample collected on the impactor surface. The reference XRD spectra for CeO2 is presented for comparison. The labels correspond to the peak angles. c Bright field TEM images of CeO2 particles at two magnifications
