Influence of natural adsorbates of magnesium oxide on its reactivity in basic catalysis

Damien Cornu, Hugo Petitjean, Guylène Costentin, Hazar Guesmi, Jean-Marc Krafft, Hélène Lauron-Pernot

Solid materials possessing basic properties are naturally covered by carbonates and hydroxyl groups. Those natural adsorbates modify their chemical reactivity. This article aims to specifically evidence the role of surface carbonates and hydroxyls in basic heterogeneous catalysis on MgO. It…

Influence of acid–base properties of Mg-based catalysts on transesterification: role of magnesium silicate hydrate formation

Damien Cornu, Longfei Lin, Maya Mounir Daou, Maguy Jaber, Jean-Marc Krafft, Virginie Herledan, Guillaume Laugel, Yannick Millot, Hélène Lauron-Pernot

The transesterification reaction assisted through heterogeneous basic catalysis was thoroughly studied because of its importance in transforming biomass, as for biodiesel production or lactone opening. As catalysts with the strongest basic properties are not always the most efficient ones, a series…

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…

Microporous polyacrylate matrix containing hydrogen bonded nanotubular assemblies

Farid Ouhib, Emmanuelle Bugnet, Andrei Nossov, Jean-Luc Bonardet, Laurent Bouteiller

We report the straightforward photo-polymn. of polyacrylate films contg. bis-urea based self-assembled nanotubes. The obtained materials are characterized by gas adsorption measurements, 129Xe NMR spectroscopy and WAXS. The presence of the bis-ureas is shown by butane adsorption (at 273 K and…

High activity of mononuclear copper present in the framework of CuSiBEA zeolites in the selective catalytic reduction of NO with NH3

Rafal Baran, Teresa Grzybek, Thomas Onfroy, Stanislaw Dzwigaj

CuxSiBEA zeolites (with x = 1–7.5 Cu wt %) prepared by a two-step postsynthesis method which consists in the first step of dealumination of parent BEA zeolite to obtain aluminum-free SiBEA support and then in the second step, of contacting the obtained material with an aqueous solution of copper…

Non-thermal plasma assisted catalytic NOx remediation from a lean model exhaust

Olivier Gorce, Hervé Jurado, Cyril Thomas, Gérald Dega-Mariadassou, Ahmed Khacef, Jean Marie Cormier, Jean Michel Pouvesle, Gérard Blanchard, Sabine Calvo, Yvanne Lendresse

No efficient catalyst presently exists for deNOx in lean burn conditions. Furthermore, actual catalysts generally deactivate during reaction. A cylindrical DBD non-thermal plasma reactor was coupled with a stable three-function catalyst in order to verify the nature of the effect of the plasma on…

Surface-induced assembly of sophorolipids

Jessie Peyre, Ahmed Hamraoui, Marco Faustini, Vincent Humblot, Niki Baccile

The surface self-assembly properties of acidic sophorolipids, a bolaform microbial glycolipids with pH-responsive properties in solution, were studied based on the chemical nature of the support and pH of the solution. Sophorolipids generally form micelles in water but formation of morphologies…

Insights into bacteriophage T5 structure from analysis of its morphogenesis genes and protein components.

Yvan Zivanovic, Fabrice Confalonieri, Luc Ponchon, Rudi Lurz, Mohamed Chami, Ali Flayhan, Madalena Renouard, Alexis Huet, Paulette Decottignies, Alan R Davidson, Cécile Breyton, Pascale Boulanger

Bacteriophage T5 represents a large family of lytic Siphoviridae infecting Gram-negative bacteria. The low-resolution structure of T5 showed the T=13 geometry of the capsid and the unusual trimeric organization of the tail tube, and the assembly pathway of the capsid was established. Although major…
