Halide-free CO 2 cycloaddition onto styrene oxide catalysed by first row transition-metal derivatives of polyoxotungstates

Jingjing Ren, Franck Launay, Richard Villanneau, Anna Proust

Quaternary ammonium salts of metal derivatives of polyoxometalates [XW11O39M(H2O)]n- (X = P, Si; M = Cr, Mn, Co, Ni, Zn) were successfully tested instead of quaternary ammonium halides as catalysts in the cycloaddition of CO2 to styrene oxide. Remarkably, they gave very satisfactory yields of…

Coupled quartz crystal microbalance – Surface enhanced Raman scattering strategy for the design and testing of aptasensors for small analytes

Médéric Lequeux, Michèle Salmain, Jean-Marc Krafft, Jakub Dostalek, Anne Vallée, Alexis Loiseau, Wolfgang Knoll, Marc Lamy de la Chapelle, Souhir Boujday

Both quartz crystal microbalance with dissipation (QCM-D) and Surface Enhanced Raman Scattering (SERS) stand at the forefront of label-free transducing techniques to trace and monitor biomolecular association events occurring at solid-liquid interfaces. Although these techniques provide highly…

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…

Electrical surface properties of nanoporous alumina membranes: influence of nanochannels’ curvature, roughness and composition studied via electrokinetic experiments

Ali Vakilinejad, Emmanuelle Dubois, Laurent Michot, Marie Jardat, Didier Lairez, Serge Durand-Vidal, Clément Guibert, Nicolas Jouault

Among classical nanoporous oxide membranes, anodic aluminum oxide (AAO) membranes, made of non-connected, parallel and ordered nanochannels, are very interesting nanoporous model systems widely used for multiple applications. Since most of these applications involve local phenomena at the…

Hybrid Hydrophobin/Gold Nanoparticles: Synthesis and Characterization of New Synthetic Probes for Biological Applications

Jane Politi, Luca de Stefano, Paola Giardina, Sandra Casale, Ilaria Rea, Jolanda Spadavecchia

We report a simple and original method to synthesize gold nanoparticles in which a fungal protein, the hydrophobin Vmh2 from Pleurotus ostreatus, mixed to cetyltetrammonium bromide (CTAB) has been used as additional component in a one-step synthesis, leading to shell-like hybrid protein-metal…

Vanadium-Substituted Phosphomolybdic Acids for the Aerobic Cleavage of Lignin Models-Mechanistic Aspect and Extension to Lignin

Louay Al-Hussaini, Franck Launay, Elena Galvez

This work deals with the aerobic oxidative cleavage of CC and CO bonds catalyzed by the Keggin-type phosphovanadomolybdic acid (H 6 [PMo 9 V 3 O 40 ], noted H 6 PV 3). The latter was synthesized by an adapted hydrothermal procedure classically used for lower vanadium content and was tested as a…

A comparative study of alanine adsorption and condensation to peptides in two clay minerals

Fabrícia de Castro Silva, Luciano Clécio Brandão Lima, Edson Silva-Filho, Maria Gardennia Fonseca, Jean-François Lambert, Maguy Jaber

The polycondensation of amino acids to oligopeptides is an important step in the origins of life, and known to be effective on several mineral surfaces. The data available on clay mineral surfaces are heterogeneous and sometimes contradictory, however. The objective of the present work is to…

Oscillatory Behavior of Pd-Au Catalysts in Toluene Total Oxidation

Tarek Barakat, Joanna Rooke, Dayan Chlala, Renaud Cousin, Jean-François Lamonier, Jean-Marc Giraudon, Sandra Casale, Pascale Massiani, Bao-Lian Su, Stéphane Siffert

In this work, the activity of bimetallic Pd-Au doped hierarchically structured titania catalysts has been investigated in the total oxidation of toluene. In earlier works, doping titania with group Vb metal oxides ensured an increased catalytic performance in the elimination of VOC molecules. A…
