Dynamic light scattering (DLS) means of particle size (nm) ± standard errors (SE) are shown for each NiO/dispersion media combination and CeO2/dispersion media combination. DLS measurements for each particle/dispersion media combination (1.6 mg/ml) were immediately performed after the specified 5 or 20 minute sonication time periods. Values presented are means of hydrodynamic diameters of particle sizes (nm) from 10 sample recordings of each nano-sized particle/dispersion media combination analyzed.
