Standardization of the Boehm titration. Part I. CO2 expulsion and endpoint determination
TL;DR: In this paper, the methods of CO 2 expulsion and endpoint determination for the Boehm titration were standardized, and it was found that to minimize errors both the NaOH titrant and HCl should be standardized prior to titration and that a back-titration is preferable for all three reaction bases.

Standardization of the Boehm titration: Part II. Method of agitation, effect of filtering and dilute titrant
TL;DR: In this paper, it was found that shaking was the optimal method for use in the Boehm titration as other methods (stirring and sonicating) affect the carbon surface.

Effects of charge redistribution on self-discharge of electrochemical capacitors
TL;DR: In this article, the effect of charge redistribution on the self-discharge profile of porous carbon (Spectracarb 2225) electrodes was examined, and it was shown that the selfdischarge due purely to charge redistribution results in the same self- discharge profile as that expected for an activation-controlled self-Discharge mechanism (the potential falls linearly with log t).

Minimizing the Nyquist-plot semi-circle of pseudocapacitive manganese oxides through modification of the oxide-substrate interface resistance
A. Allison,Heather A. Andreas +1 more
TL;DR: In this article, it was shown that the origin of the Nyquist semi-circle is in fact the oxide-substrate interface resistance, rather than the pseudocapacitive reaction's charge-transfer resistance.
