Mechanistic studies of the 'blue' Cu enzyme, bilirubin oxidase, as a highly efficient electrocatalyst for the oxygen reduction reaction
(ROYAL SOC CHEMISTRY, 2010)
The 'blue copper' enzyme bilirubin oxidase from Myrothecium verrucaria shows significantly enhanced adsorption on a pyrolytic graphite 'edge' (PGE) electrode that has been covalently modified with naphthyl-2-carboxylate ...
Simultaneous determination of Cu, Pb, Cd, Ni, Co and Zn in bioethanol fuel by adsorptive stripping voltammetry and multivariate linear regression
(Elsevier, 2014-08)
In this work it is proposed the one-voltammogram simultaneous determination of Cu(II), Pb(II), Cd(II),Ni(II), Co(II), and Zn(II) at ppb and sub-ppb levels in bioethanol fuel samples by adsorptive stripping voltammetry.Mixed ...
Theoretical model of ion transfer-electron transfer coupled reactions at the thick-film modified electrodes
(Elsevier Science Sa, 2017-01)
The theory of cyclic voltammetry of ion transfer-electron transfer coupled reactions in a thick organic film modified electrode is developed. The model system consists of a planar electrode completely covered by an organic ...
