Quantification of metallic copper and nickel in their binary mixtures by voltammetry of immobilized microparticles [PDF]

open access: yes, 2013
We report the use of voltammetry of immobilized microparticles for the quantification of metallic copper and nickel in their binary mixtures. Twenty-two electrolytes were investigated in order to obtain well-separated oxidation peaks.

Experimental and theoretical characterization of microbial bioanodes formed in pulp and paper mill effluent in electrochemically controlled conditions [PDF]

open access: yes, 2013
Microbial bioanodes were formed in pulp and paper effluent on graphite plate electrodes under constant polarization at -0.3 V/SCE, without any addition of nutriment or substrate. The bioanodes were characterized in 3-electrode set-ups, in continuous mode,

Bipolar (Bio)electroanalysis.

open access: yesAnnual Review of Analytical Chemistry, 2021
This contribution reviews a selection of the most recent studies on the use of bipolar electrochemistry in the framework of analytical chemistry. Despite the fact that the concept is not new, with several important studies dating back to the middle of ...

The Influence of Protonation on the Electroreduction of Bi (III) Ions in Chlorates (VII) Solutions of Different Water Activity [PDF]

open access: yes, 2015
We examined the electroreduction of Bi (III) ions in chlorate (VII) solutions under varied protonation conditions of the depolariser using voltammetric and impedance methods. The results of the kinetic parameter correlation lead to the statement that

Catalase-based modified graphite electrode for hydrogen peroxide detection in different beverages [PDF]

open access: yes, 2016
A catalase-based (NAF/MWCNTs) nanocomposite film modified glassy carbon electrode for hydrogen peroxide (H2O2) detection was developed. The developed biosensor was characterized in terms of its bioelectrochemical properties.

An Electroanalytical Perspective on the Competitive Interplay between Zinc Deposition and Hydrogen Evolution in Aqueous Zinc Metal Batteries

open access: yesAdvanced Energy Materials, Volume 16, Issue 1, 7 January 2026.
This perspective highlights recent electroanalytical measurement advances in aqueous zinc metal batteries (AZMBs). We describe tools that decouple competing pathways, such as zinc deposition, faradaic hydrogen evolution reaction (HER), and corrosion HER. We show how these insights can help enable the rational design of next generation AZMBs.

Integration of a sensor system into microfluidic chips [PDF]

open access: yes, 2010
There have been considerable developments in the field of potentiometric sensors in recent years mainly with respect to lowering detection limits and making sensors smaller, solid-state, robust and less expensive.[1, 2] In potentiometric measurements two

Electrochemical detection of TNT at cobalt phthalocyanine mediated screen-printed electrodes and application to detection of airborne vapours [PDF]

open access: yes, 2013
We describe the use of cobalt phthalocyanine as a mediator to improve the sensitivity for the electrochemical detection of TNT. Commercial screen-printed electrodes containing cobalt phthalocyanine were employed for determination of TNT.

Valorization of Glycerol Through 2,2,6,6‐Tetramethyl‐1‐Piperidine‐N‐Oxyl (TEMPO)‐Catalyzed Electrochemical Oxidation with High C3 Product Selectivity: Impact of Stirred Bulk Versus Flow Electrolysis

open access: yesChemElectroChem, Volume 13, Issue 1, January 2026.
2,2,6,6‐tetramethyl‐1‐piperidine‐N‐oxyl‐catalyzed glycerol electrochemical oxidation proceeds with different selectivity when comparing bulk stirred and flow electrolysis. Conversion of glycerol to value‐added products is an attractive solution to the oversupply of this byproduct of biofuel production.
