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.

Sizable studies: Mercury(I) chloride (Hg2Cl2) nanoparticles (NPs) are synthesised for the first time by using two different techniques. First, particles are formed by implosion of a calomel nanolayer, induced by partial electrolysis at a mercury hemisphere microelectrode. Second, Hg2Cl2 NPs are synthesised by the precipitation reaction between Hg2(NO3)2 and KCl. The NPs are characterised on both mercury and carbon microelectrodes by using the nanoimpact method and their size is found to agree with TEM results.

Why so uniform? Palladium on carboxylate-functionalized multiwalled carbon nanotubes (Pd–MWNT-COOH) are successfully synthesized by using a facile one-pot method involving thermal decomposition of Pd(acac)2 in the presence of MWNT-COOH without addition of reductant or surfactant. Carboxyl groups on the tube wall act as anchors and are responsible for the excellent distribution and thus contribute to the high catalytic performance of Pd–MWNT-COOH.
