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.

Getting hot in here: An electrochemical field-effect transistor setup is used for cyclic voltammetry and conductivity measurements (see picture). It includes a counter electrode (CE) and a reference electrode (RE) immersed into a drop of 5 Li-S1-cMb solvent-free melt, which comprises Li+ (green circles) dispersed in polymer-conjugated myoglobin bioconjugates.

Polka dots go quantum: A gel-like film (GF) mechanism is proposed to prepare quantum dot/graphene nanosheet (QD/GNS) fabric. Large numbers of MnO QDs are homogeneously dispersed on the GNS surface, similar to polka dot fabrics in real life. This material presents superior long-term and rate performance for lithium storage.
- Assessments of Surface Coverage after Nanomaterials are Drop Cast onto Electrodes for Electroanalytical Applications
Ya Yun Chan, Alex Y. S. Eng, Prof. Dr. Martin Pumera and Prof. Dr. Richard D. Webster
Article first published online: 17 MAR 2015 | DOI: 10.1002/celc.201500047
Incomplete coverage: The drop-casting procedure is unable to prevent solution-phase ions from diffusing all the way through the nanomaterial coating to the base electrode. Studies that utilize nanomaterial coatings on electrode surfaces need to take into account the effect of the base electrode on the overall measured current or potential.
- Electrospun Single-Phase Na1.2V3O8 Materials with Tunable Morphologies as Cathodes for Rechargeable Lithium-Ion Batteries

You spin me right round: Nanobelts with standalone and hierarchical configurations are synthesized by using a simple electrospinning technique with alterations to the sintering profile. As a potential cathode material for rechargeable lithium-ion batteries, the standalone, non-agglomerated nanobelts exhibit excellent cyclability and rate capability.
