5.0 mL anthocyanins solution (1.0 μM) was titrated by successive additions of BSA solution with the concentration of 1.0 × 10−5 mol L−1 at different conditions (T = 297, 317, 337 K).
To explain the ORR catalytic mechanism of the Co-NC-900 catalyst in acidic electrolyte, we also measured the ORR polarization curves in 0.1 mol l 1 HClO4 at different rotation speeds (400−3600 rpm), as displayed in Fig. 5c.
Polymer solutions (5.0 ml) at different concentrations were added to the vials, and the final pyrene concentration was 6 × 10−7 mol l 1 in water.

To explain the ORR catalytic mechanism of the NPNC-700 catalyst in the alkaline electrolyte, we also measured the ORR polarization curves in 0.1 mol l−1 KOH at different rotation speeds (400 3600 rpm), as displayed in Fig. 5e.
Graphs show particle size distributions in dispersions of pristine (a e) and oxidized MWCNTs (f, i) with concentration of 0.2 mg/ml in CsCl solution (C = 0.1 mol/l) at different pH.
Figures 5 represents average particle (agglomerates) size that was obtained in dispersion of pristine (a) and oxidized (b) multiwalled carbon nanotubes dispersed in electrolytes with different cation (NaCl, KCl, CsCl) or anion (NaCl, NaClO4) size at concentration of 0.1 mol/l at different pH of solutions.
Based on a previous study, Zn1 − xAlxO (AZO; Al/Zn = 1.5 mol%) thin films optimized with a Ni content of 0.5 mol% were annealed at different temperatures from 450 to 600 °C in N2/H2 (95/5) forming gas for 1 h.
Emf measurements in the formation cell Al|AlCl3 l), NaCl(l)|Cl2 were carried out at different mol fractions of AlCl3 in the range 0 < xAlCl3 < 0.5.
