Introduction. Nanofluids show a versatile spectrum of applications since they exhibit an enhancement of physicochemical and electrothermal properties of the base liquid1,2,3,4. Actually, the integration of nanoparticles of different shapes, sizes, and chemical compositions results in increased breakdown voltage5,6, lower partial discharge activity7, improved heat transfer8, and radiation-proof?performance9 through mechanisms that remain the subject of ongoing investigations. In light of th...
