Direct Electrodeposition of Gold Nanostructures onto Glassy Carbon Electrodes for Non-enzymatic Detection of Glucose
TL;DR: In this paper, Dendrite-like gold nanostructures were directly electrodeposited onto the surface of a glassy carbon electrode (GCE) via the potentiostatic method without any templates, surfactants, or stabilizers.

In Situ and Real-Time Surface-Enhanced Infrared Study of Electrochemical Reactions
Masatoshi Osawa,Katsumasa Yoshii +1 more
TL;DR: In this article, surface-enhanced infrared absorption spectroscopy (SEIRAS) in conjunction with cyclic voltammetry has been applied to in situ and real-time monitoring of the electrochemical redox reactions of heptylviologen at a silver electrode surface.

Use of cyclic voltammetry for studying two-dimensional phase transitions: Behaviour at low scan rates
TL;DR: In this article, a theoretical study of two-dimensional phase transitions taking place in electrode processes was carried out by using cyclic voltammetry, where the treatment used was applied on the assumption that the nucleation rate for the process is a function only of the concentration of nuclei of a critical size which depends on the overpotential.

TL;DR: One-electron reduction of the "extended viologen" dication 1 yields the red cation radical 2, characterized by strong near-IR absorption, which has been generated and studied by pulse radiolytic, electrochemical, redox titration, UV-visible, and electron paramagnetic resonance spectroscopic methods.

Quartz Crystal Microbalance Studies of Deposition and Dissolution Mechanisms of Electrochromic Films of Diheptylviologen Bromide
TL;DR: In this article, the deposition and dissolution mechanisms of thin films of diheptylviologen bromide were investigated using the quartz crystal microbalance (QCM) technique in conjunction with cyclic voltammetric and potential step measurements.

Theoretical and experimental studies of multiple nucleation
TL;DR: The theory of the potentiostatic current transient for three-dimensional multiple nucleation with diffusion controlled growth is discussed in this paper, where the termination of the nucleation process by the expansion of diffusion fields is considered, as well as deviations from randomness observed in the distribution of nuclei on the electrode surface.

Electrochemical nucleation: Part I. General considerations
TL;DR: In this paper, a new theory was proposed for the potentiostatic current maximum which leads to more reliable values of the nuclear number density and to a better distinction between instantaneous and progressive nucleation.

Three-dimensional nucleation with diffusion controlled growth: Part I. Number density of active sites and nucleation rates per site
TL;DR: In this article, the current transient for three-dimensional nucleation on a finite number of active sites, followed by diffusion controlled growth, has been analyzed and the true nucleation rate per site can be obtained from the current maximum of single-step potentiostatic experiments.

On the relation between nucleation work, nucleus size, and nucleation rate
TL;DR: In this paper, a general thermodynamic relation is proved between the nucleation work and the nucleus size regardless of the model for the excess free energy of the nucleus, and the relation reads as follows: the number of atoms (or molecules) in the nucleus equals the derivative with minus sign of the nucleations with respect to the supersaturation Δμ.
