Themed collection Electrochemistry at nano-interfaces

The stochastic nature of very fast single-entity events challenges current electrochemical methods and modern electronics, as illustrated using recent experiments from the authors’ laboratory.

The Faraday Discussion on electrochemistry at nano-interfaces presented a platform for an incredibly diverse array of advances in electrochemical nanoscience and nanotechnology.

We investigate the deposition, evolution and dissolution of single and two-component metal layers on Au substrates immersed in the deep eutectic solvent Ethaline.

This paper is concerned with long-distance interactions between an unbiased metal nanoparticle (NP) and a nanoelectrode employed as a tip in the scanning electrochemical microscope (SECM).

Combined to electrochemical actuation, it allows the dynamic in situ visualization of the electrochemical growth and dissolution of individual Ag nanoparticles.

Alpha-synuclein aggregates induced cell membrane disruption was observed in real time with scanning ion conductance microscopy.

The ionic conductivity of silica ionogel based solid electrolyte on meso and nanoscales is measured.

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.

We demonstrate a hydrogel-coated nanoelectrode array biosensor that is resistant to biofouling.

In this paper, we report the electrosynthesis and characterization of individual, shape-controlled Pt nanocrystals electrodeposited on carbon nanoelectrodes.

We present evidence that the “third hydrogen peak” involves surface-adsorbed hydrogen on a locally “reconstructed” (110)-type surface site.

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.

We present short cyclodextrin nanotubes that form ion channels in lipid bilayers.

Nanopipette imaging probes (ca. 30 nm) are used to map the activity/topography of nanostructured electrocatalysts directly, revealing active sites unambiguously.

Nanoporous Ag (ligament size: 21 nm) exhibits superior CO selectivity and activity, confirming strong ligament size effects on CO₂ reduction.

Here we present a methodology for probing the surface temperature at a plasmonic nanoparticle substrate using scanning electrochemical microscopy.

Vesicle impact electrochemical cytometry shows vesicular catecholamine concentration is relatively constant and independent of the vesicular size.

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.

An adjustable width (between 600 nm and 20 μm) gap between two Au microelectrodes is used to probe the electrodissolution dynamics of single Ag nanoparticles.

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.

FIB/SEM tomography and energy dispersive X-ray (EDX) spectroscopy are employed to study the interface between two immiscible electrolyte solutions at nanopore arrays, which were electrochemically modified by silica.

An ionic gate for sensing Pb²⁺ based on an emerging advanced funnel-shaped nanochannel system is reported, with enhanced stability and improved sensitivity.

We propose a method enabling the evaluation of intrinsic catalytic activity of nanoparticles based on the diffusion-limited steady-state current.

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.

The present work reveals the role of nano-interfaces on domain size and the thickness in the context of the relationship between double layer impedances and redox reactions.
