Sulfur Deactivation of NOx Storage Catalysts: A Multiscale Modeling Approach.

Nikola Rankovic, Céline Chizallet, Andre Nicolle, David Berthout, Patrick da Costa

Lean NOx Trap (LNT) catalysts, a promising solution for reducing the noxious nitrogen oxide emissions from the lean burn and Diesel engines, are technologically limited by the presence of sulfur in the exhaust gas stream. Sulfur stemming from both fuels and lubricating oils is oxidized during the…

Investigating the DMPO-formate spin trapping method for the study of paper iron gall ink corrosion

Alice Gimat, Valeryia Kasneryk, Anne-Laurence Dupont, Sabrina Paris, Frederic Averseng, Jeanine Fournier, Pascale Massiani, Véronique Rouchon

Paper degradation by iron gall ink is a challenging issue for the conservation of ancient manuscripts. It is usually attributed to both FeII catalyzed oxidation and acid catalyzed hydrolysis of cellulose, yet the dominant degradation pathway remains an open question. In this work, electron spin…

Silk bionanocomposites : design, characterization and potential applications, Bionanocomposites à base de soie : élaboration, caractérisation et applications potentielles

Cristina Belda Marín

Silk-based bionancompoistes have attracted a growing interest in numerous applications, particularly in the biomedical field, owing to their ability to combine the specific properties of silk fibroin (biodegradability, biocompatibility and interesting mechanical properties) and nanoparticles (NPs…, Les « bionanocomposites » à base de soie sont des matériaux qui suscitent un intérêt croissant dans de nombreuses applications, et en particulier dans le domaine biomédical, de par leur capacité à combiner les propriétés de la fibroïne (biodégradabilité, biocompatibilité et propriétés mécaniques…

Thiol-Poly(Sodium Styrene Sulfonate) (PolyNaSS-SH) Gold Complexes: From a Chemical Design to a One-Step Synthesis of Hybrid Gold Nanoparticles and Their Interaction with Human Proteins

Ceĺine Falentin-Daudre, Mounia Aitouakli, Jean Sebastien Baumann, Nadia Bouchemal, Vincent Humblot, Veronique Migonney, Jolanda Spadavecchia

This study highlights recent advances in the synthesis of nanoconjugates based on gold (Au(III)) complex with a bioactive polymer bearing sulfonate groups called thiol-poly(sodium styrene sulfonate) (PolyNaSS-SH) with various molecular weights (5, 10, and 35 kDa). The three nanomaterials differ…

Fe3+-doped ordered mesoporous γ-Fe2O3/SiO2 microspheres as a highly efficient magnetically separable heterogeneous Fenton catalyst

Nassira Ferroudj, Patricia Beaunier, Anne Davidson, Sébastien Abramson

Here, several γ-Fe 2 O 3 /SiO 2 nanocomposite microspheres were synthesized, characterized and tested as magnetically separable heterogeneous catalysts in an advanced oxidation process. A strong relation between the structure and the activity of these materials was evidenced. Two parameters,…

Efficiency of Polyoxometalate-Based Mesoporous Hybrids as Covalently Anchored Catalysts

Faiza Bentaleb, Ourania Makrygenni, Dalil Brouri, Cristina Coelho Diogo, Ahmad Mehdi, Anna Proust, Franck Launay, Richard Villanneau

Polyoxometalate (POM) hybrids have been covalently immobilized through the formation of amide bonds on several types of mesoporous silica. This work allows the comparison of three POM-based mesoporous systems, obtained with three different silica supports in which either the organic functions of…
