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

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

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 ...

Fabrication of clamped-clamped beam resonators with embedded fluidic nanochannel

Philippe Renaud, Luis Guillermo Villanueva Torrijo, Annalisa De Pastina, Damien Maillard, Stefano Silvio Giovanni Varricchio, Carlo Ricciardi, Davide Scaiola, Stefano Stassi

Suspended nanochannel resonators (SNRs) are promising devices able to characterize mass down to the attogram scale, thus being able to detect nanoparticles or biomolecules. In this paper, we present a flexible fabrication process for SNRs based on a sacrif ...

Formal Aza-Wacker Cyclization by Tandem Electrochemical Oxidation and Copper Catalysis

Xile Hu, Xiangli Yi

In oxidative electrochemical organic synthesis, radical intermediates are often oxidized to cations on the way to final product formation. Herein, we describe an approach to transform electrochemically generated organic radical intermediates into neutral p ...

Soluble and Solid Iron Reduction Assays with Desulfitobacterium hafniense

Julien Maillard

There is a pressing need to develop sustainable and efficient methods to protect and stabilize iron objects. To develop a conservation-restoration method for corroded iron objects, this bio-protocol presents the steps to investigate reductive dissolution o ...

Bacterial iron reduction and biogenic mineral formation for the stabilisation of corroded iron objects

Julien Maillard, Arnaud Michel Gelb

Exploiting bacterial metabolism for the stabilisation of corroded iron artefacts is a promising alternative to conventional conservation-restoration methods. Bacterial iron reduction coupled to biogenic mineral formation has been shown to promote the conve ...

The Structure of the Cobalt Oxide/Au Catalyst Interface in Electrochemical Water Splitting

Klaus Kern

The catalytic synergy between cobalt oxide and gold leads to strong promotion of the oxygen evolution reaction (OER)one half-reaction of electrochemical water splitting. However, the mechanism behind the enhancement effect is still not understood, in part ...

Silicon Heterojunction Solar Cells on Quasi-mono Wafers

Christophe Ballif, Antoine Descoeudres, Matthieu Despeisse, Mathieu Gérard Boccard, Loris Barraud, Jan Haschke, Raphaël Monnard, Brahim Aissa

We applied hydrogen passivation, gettering and a combination of both to quasi-mono (qm) wafer material to enhance its bulk lifetime and prepared silicon heterojunction (SHJ) solar cells. We find that while our applied hydrogen passivation alone seems not t ...

A 3D printed beam splitter for polar neutral molecules

Andreas Osterwalder, Sean Dennis Steven Gordon

We describe a beam splitter for polar neutral molecules. An electrostatic hexapole initially confines and guides a supersonic expansion of ammonia, and it then smoothly transforms into two bent quadrupole guides, thus splitting the molecular beam in two co ...
