Ruthenium ion containing N and S rich triazine based metallopolymer as a low overpotential acid stable electrocatalyst for hydrogen evolution

Another article by Vishwanath in his collaboration with his old Indian institute has just been published in Journal of Catalysis. In this paper they have shown a facile method for preparing thin films of Ruthenium ion containing metallopolymers chemically immobilised on the reactive electrode substrate. These electrodes exhibit a remarkable […]

SECM study of hydrogen photogeneration in a 1,2-dichloroethane | water biphasic system with decamethylruthenocene electron donor regeneration

Wojtek had another publication in the series of papers on ion-transfer for H2 and H2O2 generation at liquid|liquid interfaces. In this paper, we continue our studies on hydrogen evolution reaction (HER) at the Interface between Two Immiscible Electrolyte Solutions (ITIES). This time, we have generated hydrogen by using photoelectroactive redox […]

Generation-Collection Electrochemistry Inside a Rotating Droplet

We just had a paper published in Analytical Chemistry concerning generation-collection electrochemistry inside a rotating droplet. This is a continuation of the investigation of the rotating droplet as a small volume hydrodynamic system that was published last year in Electrochem. Commun. In this paper we generation-collection electrochemistry, meaning that we […]

Surface-enhanced Raman spectroscopy introduced into the International Standard Organization (ISO) regulations as an alternative method for detection and identification of pathogens in the food industry

Marta just had her first paper published. She prepared SERS-active substrates for a study using Raman spectroscopy to identify pathogens in food. Results described in the article (with a title so long that an abstract in not really needed) show that surface-enhanced Raman spectroscopy (SERS) combined with principal component analysis […]

Metal ions containing C3N3S3 coordination polymers chemisorbed to copper surface as acid stable hydrogen evolution electrocatalysts

Another paper from Vishwanath’s old work in India was just published in the very good Journal of Materials Chemistry A. Brilliant work! The paper concerns the creation of electrocatalysts for the hydrogen evolution reaction, something that is urgently needed if hydrogen shall be produced using sustainable amounts of energy. The […]

Rotating droplet as a new alternative for small volume electrochemical measurements

A paper from Magda’s work with a rotating droplet as alternative to rotating disc electrodes for electrochemical measurements in small volumes was just accepted in Electrochemistry Communications. This is a development of an idea from Limoges’s group in Paris, where they used a rotating disc electrode (RDE) to spin a […]

H2O2 Generation at a Carbon-Paste Electrode with Decamethylferrocene in 2-Nitrophenyloctyl Ether as a Binder: Catalytic Effect of MoS2 Particles

Another paper in the series on H2O2 generation at liquid|liquid interfaces appeared in ChemElectroChem a while back. Wojtek is a co-author together with members of the Opallo-group and Hubert Girault from Lausanne. In the paper we describe the use of a carbon paste electrode (CPE) for generation of H2O2 at […]

Compatibility of organic solvents for electrochemical measurements in PDMS-based microfluidic devices

We just had a new paper published in Microfluidics and Nanofluidics concerning the compatibility of some organic solvents with PDMS-based microfluidic devices. In a well-known study (cited ~1600 times) the Whitesides-group argued that how much PDMS swells in a solvent is a good indication of how compatible that solvent is with […]
