Analysing chronoamperometry data to determine logical gates.

, 2023
The figure displays the output of four distinct logical gates (AND, OR, XOR, and NAND) derived from the chronoamperometry data of 12 proteinoids. The output is a binary vector that indicates whether the logical condition is satisfied or not for each time

The influence of reaction-induced thermal convection on the electrical currents measured in chronoamperometry and cyclic voltammetry [PDF]

, 2016
Electrochemical reactions invariably occur with a change in the molar volume between reactant and product, as well as a change in enthalpy. These factors give rise to convective flows driven respectively by concentration and temperature and affect the ...

Dissolution of Iron and Ionisation of Hydrogen in Borate Buffer under Cyclic Pulse Polarisation

International Journal of Electrochemical Science, 2019
The dissolution of iron in a neutral borate buffer under cyclic pulse polarisation was studied. If the potential is cycled between the values that correspond to the pre-passivity of iron and cathodic hydrogen evolution, the rate of metal dissolution ...
