Covalent Grafting of Organic–Inorganic Polyoxometalates Hybrids onto Mesoporous SBA-15: A Key Step for New Anchored Homogeneous Catalysts

Richard Villanneau, Asma Marzouk, Yan Wang, Aicha Ben Djamaa, Guillaume Laugel, Anna Proust, Franck Launay

Covalent grafting of the polyoxometalate (POM) hybrid [AsW9O33{P(O)(CH2CH2CO2H)}2]5- on mesoporous NH2-functionalized SBA-15 is the first example of anchored vacant POMs in which nucleophilic oxygen atoms are still available after incorporation into the supports. Such systems are interesting…

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…

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…

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…

Smartphone-assisted plasmonic biosensors for rapid on-site detection of foodborne pathogens and allergens

Walid Ait Mammar, Axel Wilson, Antoine Miche, Thomas Kuntzel, Michèle Salmain, Souhir Boujday

We report the design of a smartphone-assisted plasmonic immunosensor and its application to the detection of several food contaminants, namely staphylococcal enterotoxin A (SEA), bovine β-lactoglobulin (BLG), and hen egg white lysozyme (LYSO). Comprehensive characterization of antibodies was…

Non-Hydroxyl Radical Species Production during Dark Air Oxidation of Alluvial Soils

Elora Bourbon, Frédéric Averseng, Pierre Le Pape, Thierry Allard, Fulvia Baratelli, Fabrice Alliot, Alexandre Gélabert, Valentine Rollot, Elodie Guigon, Jessica Brest, Sylvie Nélieu, Guillaume Morin

Natural environments subjected to hydrologically-driven redox fluctuations are regarded as propitious to contaminant degradation since they favor cyclic oxygenation of Fe(II)-minerals that produces oxidizing reactive species, such as the hydroxyl radical, OH • . However, the identity of these…

Efficient transformation of cyclohexanone to ε-caprolactone in the oxygen-aldehyde system over single-site titanium BEA zeolite

Katarzyna Pamin, Jacek Gurgul, Grzegorz Mordarski, Yannick Millot, Jean-Philippe Nogier, Laetitia Valentin, Stanislaw Dzwigaj

TixSiBEA zeolites prepared by a two-step post-synthesis method are applied in the liquid-phase Baeyer-Villiger oxidation of cyclohexanone to ε-caprolactone in the oxygen-aldehyde system. Such method of ε-caprolactone synthesis offers the application of milder reaction conditions with the catalytic…
