Selective Catalytic Reduction of NO x over Au/Al2O3: Influence of the Gold Loading on the Promoting Effect of H2 in H2-Assisted C3H6-SCR of NO x

Tesnim Chaieb, Cyril Thomas, Sandra Casale, Catherine Louis, Laurent Delannoy

This article reports on the promotional effect of adding H2 to the reaction feed for the selective catalytic reduction of NO x with propene (H2–C3H6-SCR) over Au/Al2O3 catalysts. For this purpose, the influence of the Au loading in H2–C3H6-SCR was investigated. The H2 promoting effect in C3H6-SCR,…

Dual Thermo- and pH-Responsive N -Cyanomethylacrylamide-Based Nano-Objects Prepared by RAFT-Mediated Aqueous Polymerization-Induced Self-Assembly

Nicolas Audureau, Fanny Coumes, Jean-Michel Guigner, Clément Guibert, François Stoffelbach, Jutta Rieger

We report the straightforward synthesis of dual stimuli-responsive nano-objects using a RAFT-mediated polymerization-induced self-assembly (PISA) process in water. The key to complex and tunable responsiveness was the copolymerization of N-cyanomethylacrylamide, providing UCST-type polymers, with a…

Effect of pH on the incorporation of acrylic acid units in the core of polymer nanoparticles prepared by PISA and on their morphology

Clément Debrie, Noémie Coudert, Jean-Michel Guigner, Fanny Coumes, Clément Guibert, Simon Harrisson, François Stoffelbach, Olivier Colombani, Jutta Rieger

Polymerization-induced self-assembly (PISA) is a polymerization process in which amphiphilic block copolymers are simultaneously synthesized and self-assembled in a selective solvent, leading to nanoparticles of different morphologies. Copolymerization has been reported as a means to tune…

Evidence of Pd segregation and stabilization at edges of AuPd nano-clusters in the presence of CO: A combined DFT and DRIFTS study

Beien Zhu, Gode Thrimurthulu, Laurent Delannoy, Catherine Louis, Christine Mottet, Jerome Creuze, Bernard Legrand, Hazar Guesmi

Combined Density Functional Theory (DFT) calculations and Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) were performed to study the distribution of Pd atoms in bimetallic AuPd nanoparticles in the presence of adsorbed CO. Compared to vacuum condition, the results showed…

Adsorption of chiral molecules in oxide-supported heterogeneous catalysts : a model approach, Adsorption de molécules chirales sur catalyseurs hétérogènes supportés sur oxyde : une approche modèle

Elisa Meriggio

Enantioselective heterogeneous catalysis is a method of choice for the synthesis of enantiopure chiral products. One current approach involves the modification of a metal surface by a chiral modifier. Despite its great potential, only a small number of successful systems have been developed so far…, La catalyse asymétrique hétérogène est une méthode de choix pour la synthèse de composés chiraux énantiopurs. Une approche courante implique la modification d'une surface métallique par un inducteur chiral. Malgré son potentiel, seul un petit nombre de systèmes ont été mis au point jusqu'…

Phosphorylation of a conserved serine in the deoxyribonucleic acid binding domain of nuclear receptors alters intracellular localization.

Kai Sun, Vedrana Montana, Karthikeyani Chellappa, Yann Brelivet, Dino Moras, Yutaka Maeda, Vladimir Parpura, Bryce M Paschal, Frances M Sladek

Nuclear receptors (NRs) are a superfamily of transcription factors whose genomic functions are known to be activated by lipophilic ligands, but little is known about how to deactivate them or how to turn on their nongenomic functions. One obvious mechanism is to alter the nuclear localization of…

Catalytic behavior of copper–amine complex supported on mesoporous silica SBA-15 toward mono-Aza-Michael addition: role of amine groups

Aboubakr Hakiki, Riad Mustpha Kerbadou, Bouhadjar Boukoussa, Hadjira Habib Zahmani, Franck Launay, Alain Pailleret, Françoise Pillier, Salih Hacini, Abdelkader Bengueddach, Rachida Hamacha

This work concerns the preparation and modification of mesoporous silica SBA-15 with different amine-copper complexes in order to study their impact on the catalytic behavior via Aza Michael addition. Firstly, SBA-15 was prepared hydrothermally, then functionalized by mono-, di- and tri-amine, and…
