Vanadium‐manganese redox flow battery: Study of Mn(III) disproportionation in the presence of other metallic ions

Hubert Girault, Pekka Eero Peljo, Danick Reynard, Sunny Isaïe Maye, Solène Cindy Gentil

The Mn(III)/Mn(II) redox couple with a standard potential of +1.51 V vs . SHE has drawn interest for the design of V/Mn redox flow battery (RFB). However, Mn(III) disproportionation leads to a loss of capacity, an increase of pressure drop and electrode pa ...

Compact and General Strategy for Solving Current and Potential Distribution in Electrochemical Cells Composed of Massive Monopolar and Bipolar Electrodes

Hubert Girault, Alejandro Nicolás Colli

A compact, fast and general algorithm based on Dirichlet boundary conditions for the potential field is derived to enable the calculation of local current distribution, shunt currents and the local potential distribution on massive electrodes in electroche ...

TiO2 nanoparticles suppress Escherichia coli cell division in the absence of UV irradiation in acidic conditions

Juan Kiwi

TiO2 nanoparticles (NPs) activated by UV irradiation are known to have a bactericidal effect. In this study we report the details of TiO2 NPs influence on the colony-forming capacity of E. coli in the dark at pH 4.0-4.5. At this pH the bacterial cells are ...

Anodic oxidation of phenol on Ti/IrO2 electrode: Experimental studies

Stéphane Fierro

The electrochemical oxidation of acidic solutions of phenol on a Ti/IrO2 anode has been investigated by cyclic voltammetry and bulk electrolysis in a single-compartment cell. In the potential region of oxygen evolution, anodic oxidation resulted in electro ...

Electrochemical comparison between IrO2 prepared by anodic oxidation of pure iridium and IrO2 prepared by thermal decomposition of H2IrC16 precursor solution

Christos Comninellis, Stéphane Fierro

Surface redox activities, oxygen evolution reaction (OER), oxidation of formic acid (FA), and anodic stability were investigated and compared for IrO2 electrodes prepared by two techniques: the thermal decomposition of H2IrCl6 precursor (TDIROF) and the an ...

Transport phenomena in nanofluidics : form ionic studies to proteomic applications

Reto Bruno Schoch

This thesis explores transport phenomena in nanochannels on a chip. Fundamental nanofluidic ionic studies form the basis for novel separation and preconcentration applications for proteomic purposes. The measurements were performed with 50-nm-high 1D nanoc ...

Simulation numérique des phénomènes thermiques et magnétohydrodynamiques dans une cellule de Hall-Héroult

Yasser Safa

This work is concerned with a numerical simulation of the thermal behaviour of an electrolysis cell for the production of the aluminium. Aluminium is produced by an electrolytic reduction of alumina dissolved in a bath of molten cryolite. In this reduction ...
