Linear sweep voltammetry at very small stationary disk electrodes

A Novel Approach to the Simulation of Electrochemical Mechanisms Involving Acute Reaction Fronts at Disk and Band Microelectrodes

“…Thus, for the disk electrode, the simulated chronoamperometric current deviates from the analytical approximations for short and long times made by Aoki and Osteryoung [51] by no more than 0.24 %, which is within the claimed 0.5 % accuracy of these analytical approximations (see Table 4). At the same time, the simulated steady-state current achieves its analytical value i expression provided by Aoki et al for voltammetry [53] reveals an excellent agreement (see Table 5 showing the results for a wide range of values of the dimensionless voltammetric parameter p ¼ ffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffi nFr [52] …”

Voltammetric determination of the titrable acidity of milk using a platinum microelectrode

“…The peak (I) does not change significantly in its shape or height at low scan rates, within 5-20 mV/s, where the large contribution from nonlinear diffusion gives rise to a time-independent flux [6].…”

Métodos para fabricação de microeletrodos visando a detecção em microambientes

“…[102][103][104][105][106][107][108][109][110][111][112] Dessa forma, a análise matemática dos resultados obtidos nestes casos é dificultada. 104,[107][108][109][110][111][112] Microeletrodos com geometria hemisférica não apresentam esse problema, uma vez que a densidade de corrente no estado estacionário é uniforme em toda a superfície do eletrodo. Além disso, microeletrodos não planares sofrem menos problemas de bloqueio do isolante resultantes de imprecisões no processo de isolamento da microfibra.…”
