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 […]

Pencil Lead as a Material for Microfluidic 3D-Electrode Assemblies

After long, hard effort we finally published* our research on pencil lead electrodes as electrode arrays in a microfluidic system. This was first intended as an easy-to-assemble system that could be used e.g. in experiments for high-school students or undergrads. However, from that initial, simple idea it turned out to […]

Paper-based system for ion transfer across the liquid-liquid interface

In a paper just accepted for publication in Analytical Chemistry Marta, Emilia, and Martin, together with Damien Arrigan from Curtin University, and our former intern Alexandra Pacowska, show how ion-transfer across the liquid-liquid interface can be studied in a paper-based system. One of the problems when studying ion-transfer between an organic […]
