Combined hydrogen production and electricity storage using a vanadium-manganese redox dual-flow battery
Hubert Girault, Danick Reynard
A redox dual-flow battery is distinct from a traditional redox flow battery (RFB) in that the former includes a secondary energy platform, in which the pre-charged electrolytes can be discharged in external catalytic reactors through decoupled redox-mediat ...
ELSEVIER2021Hydrogen production on demand by redox-mediated electrocatalysis: A kinetic study
Hubert Girault, Sunny Isaïe Maye, Danick Reynard
Producing hydrogen from water using a redox mediator on solid electrocatalyst particles in a reactor offers several advantages over classical electrolysis in terms of safety, membrane degradation, purity and flexibility. Herein, vanadium-mediated hydrogen ...
ELSEVIER SCIENCE SA2021Soft-probe-scanning electrochemical microscopy reveals electrochemical surface reactivity of E. coli biofilms
Hubert Girault, Emad Oveisi, Horst Pick, Andreas Stephan Lesch, Sorour Darvishi
Investigating and understanding dynamic biofilm growth mechanisms is challenging, often because state-of-theart optical characterization tools provide limited information. Micrometric electrochemical imaging of Escherichia coli biofilms using Soft-Probe-Sc ...

2021The Solvent Effect on H2O2 Generation at Room Temperature Ionic Liquid|Water Interface
H2O2 is a versatile chemical and can be generated by the oxygen reduction reaction (ORR) in proton donor solution in molecular solvents or room temperature ionic liquids (IL). We investigated this reaction at interfaces formed by eleven hydrophobic ILs and ...
2021Photonic Flash Synthesis of Mo2C/Graphene Electrocatalyst for the Hydrogen Evolution Reaction
Hubert Girault, Danick Reynard, Bhawna Nagar
Nowadays, molybdenum carbides (Mo2C) represent alternative electrocatalysts to noble metal for the hydrogen evolution reaction (HER). Here, a fast and simple process is proposed for the fabrication of Mo2C-based electrocatalysts on a carbon cloth substrate ...
AMER CHEMICAL SOC2021Rapid Noninvasive Skin Monitoring by Surface Mass Recording and Data Learning
Hubert Girault, Horst Pick, Natalia Gasilova, Andreas Stephan Lesch, Milica Jovic, Tzu-En Lin, Yingdi Zhu
Skin problems are often overlooked due to a lack of robust and patient-friendly monitoring tools. Herein, we report a rapid, noninvasive, and high-throughput analytical chemical methodology, aiming at real-time monitoring of skin conditions and early detec ...
2021Oxygen Plasma/Bismuth Modified Inkjet Printed Graphene Electrode for the Sensitive Simultaneous Detection of Lead and Cadmium
Hubert Girault, Andreas Stephan Lesch, Milica Jovic, Léopoldine Guenang Sonfack, Prachi Gupta
In this work, a simple procedure for the preparation of an inkjet printed disposable graphene electrode is reported. Commercial graphene ink was printed on a kapton substrate and the resulting electrode was 30 min treated by oxygen plasma, then modified by ...
