Why is it important?

Provides an explanation of for non-sigmoidal voltammetric responses

Perspectives

This is the key paper from my PhD. I was seeing odd shaped voltammograms similar to that observed by Prof Fraser Armstrong. We were able to show that the unexpected results were due to changes in the pathway of electron transfer from the catalytic center to the electrode.
