Quinones for Redox Flow Batteries

2021/5/4High-edge-density graphite electrodes (HEDGE) gave better results than commercially available glassy carbon or highly ordered pyrolytic graphite. The use of multi-walled carbon nanotubes (MWCNT) also provided superior results.[14]. 4.0. Conclusions

The induction heating of pyrolytic graphite

This can be most easily observed in materials of low thermal conductivity, and is here applied to pyrolytic graphite, which is a good thermal insulator normal to the surface on which it is deposited. At outer temperatures of 1000–1500C, the temperature difference across a pyrolytic graphite wall is negligible at 500 kc/s, but is remarkably large at frequencies below 10 kc/s.

The anodic strippin voltammetry of trace silver solutions

Abstract: The characteristics of the anodic stripping curves obtained from 10-11-10-7 M Ag+ have been studied using pyrolytic graphite and wax impregnated spectrographic grade carbon electrodes. It was found that the stripping curves on pyrolytic graphite electrodes (PGE) had essentially only one sharp dissolution peak, while those for wax impregnated carbon (SGE) exhibited multiple
