# Thin Layer Sonoelectrochemistry: The Solvents

## TL;DR

This paper studies how ultrasound affects electrochemical reactions in thin fluid layers, showing that solvent properties influence the reaction rates without causing cavitation or heating.

## Contribution

The study validates a model predicting TLS rate enhancements based on solvent properties using experimental data from various solvents.

## Key findings

- Rate enhancements in TLS vary with solvent properties as predicted by the model.
- No cavitation or heating is observed during TLS experiments.
- The TLS model is verified for nonaqueous solvents using voltammetry data.

## Abstract

In thin layer sonoelectrochemistry (TLS), ultrasound
induces constructive
interference in a thin fluid layer to increase interfacial rates.
In TLS experiments, slow interfacial rates are increased during and
after sonication. No cavitation or heating is observed in the fluid.
A previously developed model quantifies how solvent properties impact
TLS rates. Voltammetry for Fe3+ and benzoquinone in tetrahydrofuran,
dimethylformamide, water, ethanol, and 2-propanol is undertaken with
and without sonication. Rate enhancements vary with solvent properties,
as quantitatively predicted by the model. The data vet the TLS model
for nonaqueous solvents.
