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

Non-Invasive Probing of Nanoparticle ElectrostaticsNot 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.

  1. Nanoimpacts Reveal the Electron-Transfer Kinetics of the Ferrocene/Ferrocenium Couple Immobilised on Graphene Nanoplatelets

    The big reveal: The kinetics of the ferrocene/ferrocenium (Cp2Fe/Cp2Fe+) redox couple in aqueous solution are evaluated by using the nanoimpacts method. Single graphene nanoplatelets (GNPs) modified with poly(vinylferrocene) are allowed to impact a microelectrode. For the duration (ca. 10–100 ms) of the impacts, the GNP adopts the potential of the electrode and acts as a “chemically modified nanoelectrode”. The study of individual impacts facilitates the resolution of fast electron-transfer kinetics that, for the Cp2Fe/Cp2Fe+ couple, is shown to be at least 3±1 s−1.

  2. Reduction of Nitrophenyl Films in Aqueous Solutions: How Many Electrons?

    Four or six electrons: By analyzing the relationships between the charges for redox reactions of nitrophenyl films in strongly acidic and basic solutions, guidelines for the determination of film surface concentrations are established.

  3. Self-Supporting and Binder-Free Anode Film Composed of Beaded Stream-Like Li4Ti5O12 Nanoparticles for High-Performance Lithium-Ion Batteries

    Self-help: A self-supporting film composed of arrays of Li4Ti5O12 (LTO) nanoparticles is designed as a high-performance binder-free anode in lithium-ion batteries. The LTO nanoparticles formed in situ are closely connected along the axial direction of the pristine TiO2 nanotubes, forming a beaded stream-like structure, which boasts a high a volumetric capacity of 304 mA h cm−3 at a current density of 50 mA cm−3 as well as a high rate capability of 208 mA h cm−3 at 5000 mA cm−3.

  4. Impurities in Nitrile Solvents Commonly Used for Electrochemistry, and their Effects on Voltammetric Data

    Quality control: The voltammetric behavior of quinones and phenylenediamines can be used to detect the presence of impurities in nitrile solvents. This is especially useful for propionitrile, where the purity can vary significantly between different suppliers.
