Zeta potentials of each NiO-NP and CeO2-NP/dispersion media combination.

Medium Type NiO Zeta Potential (mV) CeO2 Zeta Potential (mV)
Pluronics −1.86 −1.40
PBS −0.06 −0.29
Survanta −0.04 −0.51
DM −0.10 −0.31

The surface charge of the NiO-NP and CeO2-NP in each dispersion media was analyzed using a Malvern Zetasizer Nano ZS instrument (Malvern Instruments Inc., UK). The electrophoretic mobility of the nanoparticles in each dispersion media was converted into the zeta potential by utilizing the Helmholtz-Smoluchowski equation.
