Multi-scan cyclic voltammetry of a solution containing mixed valence states
Autor: Keith B. Oldham, Jan C. Myland
Publikováno v: Journal of Solid State Electrochemistry. 23:3355-3361
When both members of a redox pair are present in a voltammetric cell, the applied signal must start at the null potential if pure cyclic voltammetry is to be conducted. Here the current from a limitless number of repetitive cyclic scans is predicted

Pitfalls in the application of statistics to chemical data: the determination of the partition ratio $$K_{\mathrm{ow} }$$ K ow as a case in point
Autor: Keith B. Oldham, Jan C. Myland, Donald Mackay, J. Mark Parnis
Publikováno v: Journal of Mathematical Chemistry. 56:1407-1427
Nowadays those who make replicate measurements of physicochemical properties usually employ spreadsheets or handheld devices to perform averaging and other statistical operations. Using the determination of a partition ratio as an exemplary procedure

Jacobian elliptic functions describe the properties of the diffuse charge region in narrow electrochemical cells
Autor: Keith B. Oldham, Jan C. Myland
Publikováno v: Journal of Mathematical Chemistry. 56:1184-1205
Diffuse double layers merge in narrow electrochemical cells. The distribution of ions, and the accompanying electrical properties, are predicted under static conditions that are mild enough not to engender electrochemical reactions. The predictions r

Theory of unsupported, steady-state, Nernstian, three-ion, twin-electrode, voltammetry: the special case of dual concentration polarization
Autor: Keith B. Oldham, Frank Marken, Jan C. Myland
Publikováno v: Journal of Solid State Electrochemistry. 20:3083-3095
Steady-state voltammetry is easily attained in narrow cells. Here we develop an exact mathematical description of one of the simplest instances, in which a redox pair is present, but without supporting electrolyte. The Nernstian oxidation that depola

How does a reversible electrode respond in a.c. voltammetry? Part 1: An analytic solution for the semiintegral for amplitudes less than 40mV
Autor: Jan C. Myland, Keith B. Oldham
Publikováno v: Journal of Electroanalytical Chemistry. 754:165-172
It proves possible to analyze exactly the electrode response in reversible a.c. voltammetry without resorting to simulation. The procedure involves segmenting the timescale and deducing the semiintegral. In this study, the temporal evolution of each

The excess current in cyclic voltammetry arising from the presence of an electrode edge
Autor: Keith B. Oldham, Jan C. Myland
Publikováno v: Journal of Solid State Electrochemistry. 18:3259-3269
The popular inlaid disc electrode suffers from an edge effect that is usually, and sometimes unwarrantedly, ignored in analyzing transient voltammograms. This study addresses the role played by the edge in linear scan and cyclic voltammetries when th

The aperiodic current, and its semiintegral, in reversible a.c. voltammetry: Theory and experiment
Autor: Keith B. Oldham, Alan M. Bond, Elena Mashkina, Alexandr N. Simonov, Jan C. Myland
Publikováno v: Journal of Electroanalytical Chemistry. 719:113-121
There is difficulty in attaching a precise meaning to the term “aperiodic component” in the context of a.c. voltammetry. Once this difficulty is circumvented, it becomes possible to use a filter or Fourier processing to model the dependence of th

The effect of periodic modulation on the aperiodic current in linear-scan and cyclic voltammetries
Autor: David J. Gavaghan, Jan C. Myland, Keith B. Oldham
The modulation of a ramped potential applied to a voltammetric electrode evokes two responses: a quasiperiodic 'ac' current of the same periodicity as the modulation, and a perturbation of the underlying dc current. The latter is the subject of this

Modelling cyclic voltammetry without digital simulation
Autor: Keith B. Oldham, Jan C. Myland
Publikováno v: Electrochimica Acta. 56:10612-10625
A semi-analytical method of modelling cyclic voltammetry is described, derived, exemplified, verified, and advocated. A listing of the mechanistic schemes that can be addressed by the procedure includes E, EE, CE, EC and ECE, all with various degrees
