Illuminating nanostructured gold electrode: surface plasmons or electron ejection?

We used a surface-plasmon-active gold-mushroom-array as a working electrode and observed enhanced faradaic current from ferrocenemethanol following illumination with a xenon lamp. The photoelectric current behaved differently in the presence and absence of oxygen in the solution.

Unexpected ionic transport behavior in hydrophobic and uncharged conical nanopores

We investigated ionic transport behavior in the case of uncharged conical nanopores. We observed unexpected ionic transport behaviour, which is attributed to a predominant effect of slippage due to water organization at the solid/liquid interface.

Measuring a frequency spectrum for single-molecule interactions with a confined nanopore

The time-domain nanopore signal is preciously converted into energy–frequency–time spectra with high frequency resolution and high time resolution using the Hilbert–Huang transform for revealing the detail behaviours of single-molecule weak interactions.

Charge transport at a molecular GaAs nanoscale junction

The use of semiconducting electrodes in molecular junctions is an elegant way to impart new properties to nanodevices. Here we report metal-molecule(s)–metal Schottky photodiodes whose behaviour can be tuned by appropriate choice of molecule and doping density, giving further insights into the molecule–semiconductor interface.

A study of dynamic nanoscale corrosion initiation events using HS-AFM

Using HS-AFM measurements it was possible to calculate, and subsequently model, the volumes of metal reacting with respect to time, and so the current densities and ionic fluxes at work. In this manner, the local electrochemistry at nanoscale reaction sites may be reconstructed.

About this collection

We are delighted to share with you a selection of the papers which will be presented at our Faraday Discussion on Electrochemistry at Nano-interfaces taking place in Bath, UK in June 2018. More information about the event may be found here: http://rsc.li/nanointerfacesfd2018. Additional articles will be added to the collection as they are published. The final versions of all the articles presented and a record of the live discussions will be published after the event.

The active nano-interface is important in electrochemistry because it constitutes the place where electron/ion transfer reactions occur coupled to extremely fast mass transport and under exquisite control of local conditions. Electrochemistry at nano-interfaces poses major fundamental and conceptual challenges in physical electrochemistry, while also being central to the emergence of real applications. Nano-interfaces are a major theme in energy transforming technologies (

e.g.

batteries, fuel cells, solar cells), electrochemical biosensors, diagnostic platforms, in bio-electrochemistry, and in nano-electrochemical mapping/imaging techniques. All of these areas face common challenges linked to the nano-interface concept.
