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.

Active support: A vanadium nitride/porous graphitic nanocarbon (VN/PGNC) composite is synthesized as an efficient support for Pt electrocatalyst for the oxygen reduction reaction (ORR). The designed Pt–VN/PGNC catalyst exhibits higher ORR activity and better stability than the commercial 20 % Pt/C catalyst.

Make the arrangements: Control of atom arrangement is a powerful tool for tuning the properties of pure ferromagnetic materials. By controlling Fe and Co atom stacking to form different nanostructured FeCo films using alternating current electrodeposition, a range of microwave properties are successfully tailored from this pure high-magnetic-moment alloy.

Watching the coverage: A synergistic interplay between CO and biphosphate adsorption occurs, so that increased biphosphate adsorption is visible with increasing amounts of CO in the gas feed (below 3–4 % in H2), apparently because small amounts of CO adsorption force more localization of the phosphate, which is believed to be adsorbed on top of the existing H overlayer.
