Silver Island Film for Enhancing Light Harvesting in Natural Photosynthetic Proteins

And the next paper in the silver nanostructure series with our neighbours in the Surface Nanoengineering group and the Maćkowski group in Toruń. This time its a review of how Silver Island Films (SIFs) affect the properties of light-sensitive proteins. Here, experiments were done with proteins such as peridinin-chlorophyll-protein (PCP) or the Fenna–Matthews–Olson (FMO) complex, […]

Electrochemical reduction of 7,7,8,8-tetracyanoquinodimethane at the n-octyl pyrrolidone/water/electrode three-phase junction

Continuing our investigations of the behaviour of various redox probes at three-phase electrodes we have just published a paper looking at TCNQ (7,7,8,8-tetracyanoquinodimethane) in a standard droplet-based setup. The reason we choose TCNQ is that it’s a quinone related to the ones we studied in our previous publication on transfer […]

Electrochemical Detection of Dopamine and Serotonin in the Presence of Interferences in a Rotating Droplet System

After quite a bit of work Magdalena published her research on using the rotating droplet for detection of neurotransmitters. The key point is that by using the rotating droplet, we can perform hydrodynamic measurements in volumes of only a few tens of microliters. Combining this with an electrode modification that […]

Anodic fabrication of nanostructured CuxS and CuNiSx thin films and their hydrogen evolution activities in acidic electrolytes

This is the latest paper in Vishwanath’s collaboration with his former group in India. In this study, they describe a simple route for direct fabrication of nanostructured copper sulphide and hybrid copper–nickel sulphide thin film electrocatalysts by direct anodization of reactive metal electrodes in sulphide ion containing electrolytes. This method […]

Facilitated cation transfer at a three-phase junction and its applicability for ionophore evaluation

We’re on a roll. Another cation transfer paper was accepted1, also in Electrochimica Acta. This is work done by Marta and our undergrad student Julia. They were investigating transfer of cations at the three-phase junction driven by reduction of the fullerene C60 and facilitated by the addition of ionophores to […]

Electrochemistry of selected quinones at immiscible n-octyl-2-pyrrolidone/aqueous interface using a three-phase electrode system

Vishwanath’s research on cation transfer at a three-phase junction was just published1 in Electrochimica Acta. This paper looks at transfer of cations driven by a redox reaction in an organic droplet immobilised on the electrode surface. The droplet is small enough not to cover the whole electrode area, so a […]
