Membrane electrode assembly simulation of anion exchange membrane water electrolysis

Jan Van Herle, Suhas Nuggehalli Sampathkumar, Khaled Lawand, Zoé Mury

Anion exchange membrane water electrolysis (AEMWE) offers a green hydrogen production method that eliminates the need for platinum group metals (PGM) as electrocatalysts. This study employs a COMSOL (R) 6.0 model to simulate a 1x1 cm(2) Ni fibre - Raney (R ...

Mapping of Chemical Heterogeneity at Surfaces with High-Throughput Wide-Field Second Harmonic Microscopy

Igor Nahálka

Many industrial processes are based on electrochemical reactions using engineered electrocatalysts. However, the current lack of theoretical knowledge obscures efforts to maximize catalysts' efficiency, and the optimization process is mostly empirical. To ...

Inkjet-printed microtiter plates for portable electrochemical immunoassays

Hubert Girault, Frédéric Gumy, Andreas Stephan Lesch, Fernando Cortes Salazar, Milica Jovic, Yingdi Zhu, Alexandra Bondarenko

Herein, we present the large-scale fabrication of multiplexed three-electrode sensors used in a point-of-care device platform that couples a magnetic bead-based immunoassay strategy with amperometric detection for rapid and highly sensitive analysis. The m ...

Cathodic pretreatment improves the resistance of boron-doped diamond electrodes to dopamine fouling

Martinus Gijs, Raphaël Etienne Jean Trouillon

The resistance of cathodically and anodically treated boron-doped diamond electrodes to dopamine fouling was investigated. It was found, using cyclic voltammetry and electrochemical impedance spectroscopy, that the cathodic preparation offers an increased ...

Simultaneous detection of iodine and iodide on boron doped diamond electrodes

Christos Comninellis, Stéphane Fierro

Individual and simultaneous electrochemical detection of iodide and iodine has been performed via cyclic voltammetry on boron doped diamond (SOD) electrodes in a 1 M NaClO4 (pH 8) solution, representative of typical environmental water conditions. It is fe ...

Elsevier Science Bv2013

The electrochemical behavior of a promising hydrogen/bromine redox flow battery is investigated for grid-scale energy-storage application with some of the best redox-flow-battery performance results to date, including a peak power of 1.4 W/cm(2) and a 91% ...
