Surface enhanced vibrational spectro-electrochemistry of endonuclease III provides direct evidence that the [4Fe-4S] cluster is responsible for the enzyme redox activity, and that this process is not exclusively DNA-mediated, as currently proposed. We report the first surface enhanced resonance Raman spectrum of a [4Fe-4S](2+) cluster containing enzyme.

The combination of visible light, photovoltaics, and electrochemistry provides a convenient, inexpensive platform for conducting a wide variety of sustainable oxidation reactions. The approach presented in this article is compatible with both direct and indirect oxidation reactions, avoids the need for a stoichiometric oxidant, and leads to hydrogen gas as the only byproduct from the correspond...

Gas-phase electrochemistry: The direct hydroxylation of benzene to phenol was investigated using an electrochemical cell. The production of phenol over a VO(x) anode was found to be significant at 50 °C. The resultant current efficiency for phenol production and selectivity toward phenol reached 76.5 and 94.7 %, respectively.

Advances in Electrochemistry! This Virtual Issue on Advances in Electrochemistry highlights the rich diversity in the exciting and dynamic field of electrochemistry.

Hemoglobin (Hb) in the hyaluronic acid (HA) was cast at pyrolytic graphite (PG) electrodes for researching its electrochemical and electrocatalytic properties. The formal potential and electron transfer rate constant of Hb on HA films were determined, and the stability of the films, the pH effect, and the influence of supporting electrolyte concentrations upon Hb electrochemistry on the films w...

The direct electrochemistry of human, bovine and porcine cytochrome P450c17 (CYP17) has been examined on an edge-oriented pyrolytic graphite electrode. The recombinant protein was immobilized on an electrode modified with a surfactant to simulate the environment of a biological membrane, and hence physiological electron-transfer conditions. The P450 enzymes all retained 'electron-transfer' acti...
