Coupling morphological evolution and multiphase transport to Decipher degradation in PEM water electrolyzers

Youssef Kharchouf, Loïc Assaud, Mireille Turmine, Vincent Vivier

In this work, we present a multiphase numerical model for the corrosion degradation of proton exchange membrane water electrolyzers. The numerical framework comprises two main components, a geometry tracking component and a performance evaluation component. The geometry tracking is based on the…

From 8-hydroxy-5-sulfoquinoline to new related fluorogenic ligands for complexation of aluminium(III) and gallium(III)

Franck Launay, Valérie Alain-Rizzo, Émilie Destandau, Nathalie Ramos, Ēlisabeth Bardez, Paul Baret, Jean-Louis Pierre

The hexadentate tripodal ligand O-TRENSOX (already known as a siderophore), incorporating three 8-hydroxy-5- sulfoquinoline (8-HQS) subunits, was investigated as a potential Ñuorogenic ligand of Al(III) and Ga(III). For the sake of comparison, every chelation study was also carried out with n-BUSOX…

Development of a thermodynamic approach to assist the control of the precipitation of hydroxyapatites and associated calcium phosphates in open systems

Corentin Reynaud, Cyril Thomas, Sandra Casale, Sophie Nowak, Guylène Costentin

The understanding of the precipitation mechanisms of calcium phosphates (CaPs) remains extremely challenging despite its fundamental interest for material sciences and its practical implications in medicine, paleosciences, and chemistry, especially for heterogeneous catalysis. The competitive…

Dimerization of Uracil in a simulated Mars-like UV radiation environment

Laura Rouquette, Fabien Stalport, Hervé Cottin, Cyril Colas, Thomas Georgelin, Naïla Chaouche-Mechidal, Jerome Lasne, Sara Mahfouf, Franćois Raulin, Laura Selliez, Cyril Szopa, Patrice Coll

The search for organic molecules at the surface of Mars is a key objective in astrobiology, given that many organic compounds are possible biosignatures and their presence is of interest with regard to the habitability of Mars. Current environmental conditions at the martian surface are harsh and…

Brake wear (nano)particle characterization and toxicity on airway epithelial cells in vitro

Chloé Puisney, Evdokia K Oikonomou, Sophie Nowak, Alexandre Chevillot, Sandra Casale, Armelle Baeza-Squiban, Jean-François Berret

Particulate air pollution results from different sources, among which those related to road traffic have a significant impact on human health. Combustion-derived particles emitted by thermal engines have been incriminated and are now better controlled. In contrast, non-exhaust emission sources…

Polypyrrole nanostructures modified with mono- and bimetallic nanoparticles for photocatalytic H2 generation

Xiaojiao Yuan, Diana Dragoe, Patricia Beaunier, Daniel Bahena Uribe, Laurence Ramos, Maria Guadalupe Méndez-Medrano, Hynd Remita

Conjugated polymer polypyrrole nanostructures modified with bimetallic (Pt–Ni) nanoparticles are very active for hydrogen generation and a synergetic effect is obtained by alloying Pt with Ni.

Molten Salts‐Driven Discovery of a Polar Mixed‐Anion 3D framework at the nanoscale: Zn4Si2O7Cl2, Charge Transport and Photoelectrocatalytic Water Splitting

Ram Kumar, Yang Song, Anissa Ghoridi, Philippe Boullay, Gwenaelle Rousse, Christel Gervais, Cristina Coelho Diogo, Houria Kabbour, Capucine Sassoye, Patricia Beaunier, Victor Castaing, Bruno Viana, Maria Luisa Ruiz Gonzalez, José Gonzalez Calbet, Christel Laberty-Robert, David Portehault

Mixed-anion compounds widen the chemical space of attainable materials compared to single anionic compounds, but the exploration of their structural diversity is limited by common synthetic paths. Especially, oxychlorides rely mainly on layered structures, which suffer from low stability during…

Advantages of Covalent Immobilization of Metal‐Salophen on Amino‐Functionalized Mesoporous Silica in Terms of Recycling and Catalytic Activity for CO 2 Cycloaddition onto Epoxides

Matthieu Balas, Sébastien Beaudoin, Anna Proust, Franck Launay, Richard Villanneau

NiII and MnIII Schiff base complexes (Salophen-Ni and Salophen-MnCl) bearing a pending carboxylic group were prepared and characterized. Both complexes were grafted onto a mesoporous amino-functionalized SBA-15 silica, by formation of an amide function between the propylamine groups of the support…

Loop-stabilized BAB triblock copolymer morphologies by PISA in water

Pauline Biais, Patricia Beaunier, François Stoffelbach, Jutta Rieger

A straightforward strategy to synthesize in water, loop-stabilized particles via PISA is developed. These particular structures can in theory be obtained through the synthesis of amphiphilic BAB triblock copolymers, starting from a hydrophilic middle block A, which is chain extended in an aqueous…

Gold Nanoparticle-Driven Phenylketonuria Monitoring via Colorimetric Biosensing of Phenylalanine

Alexis Loiseau, Zihua Yang, Lu Zhang, Anne Vallée, Michèle Salmain, Souhir Boujday

Phenylalanine has long been recognized as a reliable biomarker for the diagnosis and monitoring of phenylketonuria (PKU), a rare genetic disease characterized by the impairment of phenylalanine hydroxylase. As part of the current efforts toward the design of point-of-care devices for the day-to-day…
