• electrocatalysts (both supported and supportless) were evaluated with the help of Tafel plots (Figure 4b). The lower Tafel slope of the ACC-2 sample (69 mV·dec−1) showed better electrokinetics than that of ACC-1 (86 mV·dec−1), unsupported ACC-2* (141 mV·dec−1), and ACC-3 (131 mV·dec−1). Figure 4c reveals the

• and lower Tafel slope (giving rise to better electrokinetics) are the main reasons for the superior ORR performance of the ACC-2 sample. In addition to the catalyst size, morphology, conductivity, and the exposure of active sites, the surface wettability of the electrocatalyst significantly governs

Its applicability on other Newtonian fluids with properties such as polarity and even on non-Newtonian fluids should be further validated. 2.2 Surface charge effects Investigating electrokinetics phenomena, including electro-osmosis

In addition, the hydrodynamic slippage at the solid–liquid interface can in turn largely enhance the electro-osmotic velocity, which increases the urgency for a deep research on the liquid slippage phenomena in electrokinetics.

For instance, it has been reported
