Not what you might think: A new and non-invasive technique to probe the electrostatic interaction between surface-charged nanoparticles and a charged metal/solution interface shows that electrostatic effects are insignificant in all but very dilute electrolytes.

Unbiased and efficient: Plane-recessed disk-electrode arrays are extremely useful for sensing purposes, even when the top-plane electrode is not biased. This theoretical study provides insights into the bipolar performance of such systems and shows that rational design may allow their optimization for a broad range of experimental conditions.

Fast and furious: The interplay between catalytic reaction, diffusive permeation of the substrate, and diffusion-like transport of charge is analyzed for fast catalytic reactions as a function of two dimensionless parameters. These analyses also provide bases for the rational benchmarking of catalysts.
- Comparison of Cyclic and Square Wave Voltammetry of Irreversible EC Mechanisms

A theoretical model of EC mechanisms that consist of a reversible electrode reaction and a totally irreversible chemical reaction is developed for cyclic and square wave voltammetry. Simulation of square wave voltammograms for frequencies of 33 Hz (broken line) and 100 Hz (solid line) demonstrates the possibility that there is a critical frequency below which the response is small and apparently irreversible and above which it is high and appears reversible.
