Nanoelectrochemistry: metal nanoparticles, nanoelectrodes, and nanopores.
TL;DR: This review of “nanoelectrochemistry” involves a necessary arbitrariness of defining what “nano” means, and attention will be biased toward metal nanoparticles having dimensions of only a small number of nanometers, because it is in the 10 nm and lower size range where many significant recent advances have been made.
Journal ArticleDOI
Ultramicroelectrodes in Electrochemistry
TL;DR: In this paper, the changes in mass transport conditions bring about extremely high current densities at ultramicroelectrodes, whereas the currents themselves become very small, which allows for many electroanalytical applications that are not possible with conventional electrodes, especially experiments in solutions with very low electrolyte concentrations.

A microelectrode study of the mechanism and kinetics of the ferro/ferricyanide couple in aqueous media: The influence of the electrolyte and its concentration
C. Beriet,D. Pletcher +1 more
TL;DR: In this paper, the influence of the cation of the base electrolyte and its concentration (0-1 mol dm−3) on the oxidation of ferrocyanide to ferricyanide in aqueous solutions is investigated using platinum microdisc electrodes.

Fabrication of carbon microelectrodes with an effective radius of 1 nm
Shengli Chen,Anthony Kucernak +1 more
TL;DR: In this article, a method for producing insulated nanometer-sized carbon electrodes is presented, where electrodes are produced using electrochemical etching of carbon fibers followed by deposition of electrophoretic paint.
Journal ArticleDOI
Graphene Nanoelectrodes: Fabrication and Size-Dependent Electrochemistry
TL;DR: The electrodes thus fabricated are used to study the heterogeneous electron transfer (ET) kinetics at r-GOs and the nanoscopic charge transport dynamics at electrochemical interfaces and are found to exhibit similarly high activity for electrochemical ET reactions to metal electrodes.

Scanning electrochemical microscopy. Introduction and principles
TL;DR: In this paper, different modes of operation for the SECM are discussed, including collectlon modes, where products electrogenerated at the substrate are detected at the tip (held at constant potentlal or operated In the cyclic voltammetrlc mode), and feedback modes where the effect of substrate on the tlp current is monltored.

Electrochemical kinetics at microelectrodes: Part V. Migrational effects on steady or quasi-steady-state voltammograms
TL;DR: In this article, an analytical formulation for the increase or decrease of the current in steady-state or quasi-steady-state voltammograms is established for the case where the concentration of the inert electrolyte is low, and thus migration can play a role in the flux of electroactive species.
Journal ArticleDOI
Theory of microelectrode voltammetry with little electrolyte
TL;DR: In this paper, general theoretical relationships are derived that apply to steady-state voltammetry at hemispherical microelectrodes for any electrode reaction and any solution composition, and these relationships are then applied to two typical systems: the oxidation of ferrocene and the reduction of a quinone.
Journal ArticleDOI
Electrochemical kinetics at microelectrodes: Part IV. Electrochemistry in media of low ionic strength
TL;DR: In this article, a general simplified formulation of two coupled partial derivative equations is presented for situations corresponding to achievement of quasi-steady state behavior, which is shown to be directly transposable to electrodes of spherical geometry under steady-state conditions.
