Hybrids carbon quantum dots as new nanofluids for heat transfer enhancement in wet cooling towers

Low Temperature Synthesis of Fluorescent Carbon Dots from Pomegranate Peels

“…In order to investigate the stability of the C-dots in water, measurement of the Zeta potential was made. From literature, a zeta potential value of ±30 mV is physically stable and that a value of ±60 mV is completely stable [17]. In general, a higher Zeta potential value indicates a higher degree of electrostatic repulsion between adjacent particles in dispersion, indicating strong colloidal stability and as well high resistant to agglomeration.…”
