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.

Time to get organized: Experimental observations are reported for reducing the bandgap of self-organized highly oriented TiO2 nanotube arrays with enhanced and controlled tube ordering, crystallinity, and geometry of pores. The effect of two different nanotube geometries (wall thickness to pore diameter) are studied. The two geometries are achieved by anodic oxidation of Ti at 0 and 30 °C. The effect of either geometry is studied independently of the bandgap and the ordering effect is clear for each condition.
- Nickel-Foam-Supported Co3O4 Nanosheets/PPy Nanowire Heterostructure for Non-enzymatic Glucose Sensing
Hongxiu Dai, Dr. Meng Lin, Nan Wang, Fei Xu, Donglei Wang and Prof. Houyi Ma
Version of Record online: 27 FEB 2017 | DOI: 10.1002/celc.201600919
Construction zone: The Co3O4/PPy nanostructure possesses structural features of a nanowire core and nanosheet shell grown directly on a nickel foam substrate by electrochemical deposition processes. The PPy nanowires are introduced onto the nickel foam, which create a three-dimensional structure and the Co3O4 nanosheets shell act as a catalyst for the electro-oxidation of glucose.

Bound together: The unusual electrochemical behaviour of cytochrome c at liquid−gel and liquid−liquid interfaces reveals the formation of protein oligomers under electrochemical conditions. Experimental investigations using voltammetry, adsorptive stripping and electrophoretic separations are reported.
