In electrochemistry, the Nernst equation is an equation that relates the reduction potential of an electrochemical reaction (half-cell or full cell reaction) to the standard
electrode potential, temperature, and activities (often approximated by concentrations) of the chemical species undergoing reduction and oxidation.
The various current versus
electrode potential relationships for the anodic and cathodic reactions are assumed to be subject to activation control with logarithmic (Tafel) polarization behavior.
A more cathodic
electrode potential (in the hydrogen evolution direction) leads to (i) larger hydrogen oxidation currents and (ii) a shift of hydrogen oxidation towards more positive potentials.
To determine the best current density and
electrode potential domain to be applied to favor both the electro-Fenton process (cathodic [H.sub.2][O.sub.2]) and the anodic oxidation (anodic OH), a microelectrolysis study was performed.
PC cointercalation is well known to occur at ~1 V versus [Li.sup.+]/Li, hindering the lowering of the
electrode potential to values corresponding to lithium intercalation (0.25-0.0 V versus [Li.sup.+]/Li) and thus inducing graphite exfoliation prior to lithium intercalation during the first charging.
Touch in different parts of the screen is done experimentally and simulated in MATLAB, then for each point of touch,
electrode potential is recorded in two modes.
The
electrode potential reported in this work was against the saturated calomel electrode (SCE).
The
electrode potential of the control group is then
