Congratulations to Dawid. The first of two papers from his visit to Frank Marken in Bath just appeared online.

The paper is about electrocatalytic conversion of the model antioxidant diphenylcarbinol (DBC) by the mediator TEMPO (2,2,6,6-
tetramethyl-1-piperidinyloxy). In this case the DBC is a solid crystal on the electrode surface and the product also a solid. This arrangements allows the process to be approximated as a first-order reaction which makes it possible to extract the reaction rate from a single chronoampereometric measurement. Dawid measured and compared the reaction rate using several different TEMPO derivatives as mediators.

The paper was published in Journal of Solid State Electrochemistry, doi: 10.1007/s10008-014-2722-6.
