VIP: Non-Invasive Probing of Nanoparticle Electrostatics
Dr. Kristina Tschulik, Dr. Wei Cheng, Dr. Christopher Batchelor-McAuley, Stuart Murphy, Dr. Dario Omanović and Prof. Dr. Richard G. Compton
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.

Fine tuning: The combined effects of solution conditions and macrocyclic structure determine the redox behavior of free-base porphyrins in acidic nonaqueous media. Each porphyrin undergoes two reductions at the π-ring system, which occur in well-separated or overlapping electron-transfer steps at potentials between 0.00 and −1.36 V versus a saturated calomel electrode.

Positive exchange: A proton-exchange membrane fuel cell is integrated with active anode materials including vanadium and tin ions, for which redox reactions occur at more positive potentials than for hydrogen reduction. These redox couples are demonstrated to function as promising energy-storage media with excellent reversibility and good cyclability.
