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.

In pole position: Solid-state, polymer-based, light-emitting electrochemical cells incorporating bipolar electrodes (BPEs) positioned between the driving electrodes are presented. The dominant processes in these planar electrochemical cells are in situ electrochemical p and n doping of the luminescent conjugated polymer when a sufficient voltage bias is applied. The inclusion of floating BPEs causes additional doping at the extremities of the BPE.

To cap it off: Vertically aligned carbon nanotubes are selectively modified at one end with an organic layer through the bipolar electrochemical reduction of diazonium salts. The grafted organic layer, which is revealed by coupling with negatively charged gold nanoparticles, is located exclusively on the inner tube surface.
