Effect of pore geometry of mesoporous supports on catalytic performances in methane reforming

Joy Tannous, Leila Karam, Marie-Nour Kaydouh, Henri El Zakhem, Nissrine El Hassan, Sandra Casale

Catalysts prepared using three dimensional SBA-16 silica support (composed of micropores and cage-like mesopores) were tested in the reaction of methane dry reforming, in comparison with 2D hexagonal mesoporous SBA-15 support. The samples were evaluated by N 2 sorption and X-Ray diffraction (XRD)…

Joint Constellation Design for Noncoherent MIMO Multiple-Access Channels

Khac-Hoang Ngo, Sheng Yang, Maxime Guillaud, Alexis Decurninge

We consider the joint constellation design problem for the noncoherent multiple-input multiple-output (MIMO) multiple-access channel. By analyzing the noncoherent maximum-likelihood (ML) detection error, we propose novel design criteria so as to minimize the error probability. Our first criterion…

A common precursor to both prebiotic and biological pathways to RNA nucleotides

Andrea Pérez-Villa, Thomas Georgelin, Jean-François Lambert, Marie-Christine Maurel, François Guyot, A. Marco Saitta, Fabio Pietrucci

Understanding the mechanism of spontaneous formation of ribonucleotides under realistic prebiotic conditions is a key open issue of origins-of-life research. In cells, de novo and salvage nucleotide enzymatic synthesis combines 5-phospho-α-D-ribose-1-diphosphate (α-PRPP) and nucleobases.…

Carbon Dioxide Reforming of Methane over Nickel-Supported Zeolites: A Screening Study

Carmen Bacariza, Leila Karam, Nissrine El Hassan, José Lopes, Carlos Henriques

As the utilization of zeolites has become more frequent in the dry reforming of methane (DRM) reaction, more systematic studies are required to evaluate properly the influence of zeolites’ composition and framework type on the performance. Therefore, in this work, a step-by-step study was performed…

The concentration of bone-related organic additives drives the pathway of apatite formation

Marc Robin, Camila B Tovani, Jean-Marc Krafft, Guylène Costentin, Thierry Azaïs, Nadine Nassif

Bone models set for studying apatite mineralization tend to use excess of organic additives and a very low concentration of collagen in the light of those described in the biological tissue. However, the activity of soluble additives during mineral deposition is highly dependent on their…

Carbon nanowalls functionalization for efficient O2 reduction catalyzed by laccase using design of experiment

Achraf Blout, Jérôme Pulpytel, Shinsuke Mori, Farzaneh Arefi-Khonsari, Christophe Méthivier, Alain Pailleret, Claude Jolivalt

An enzymatic biofuel cell cathode was elaborated by nano-structuration and functionalization of graphite using two consecutive plasma treatments before immobilization of laccase as a biocatalyst to perform oxygen reduction reaction (ORR) by direct electron transfer ((DET). Nano-structuration of…

Synthesis of supported ZSM-5 nanoparticles

Olfa Ben Moussa, Ilef Borghol, David Hu, Sandra Casale, Yannick Millot, Celine Sayag, Juliette Blanchard, Olivier Durupthy

The influence of the support on the nucleation of ZSM-5 nanoparticles has been studied for three supports: γ-alumina, zirconia and carbon nanotubes (CNT). While zeolite nucleation was suppressed in presence of alumina and strongly delayed in presence of zirconia, it occurred without delay in…

Adsorption of dyes from aqueous solution under batch mode using cellulosic orange peel waste

Sami Guiza, Launay Franck, Mohamed Bagané

The present work aimed at studying the use of orange peel (OP) biosorption for the removal of methylene blue (MB) and Congo red (CR) from aqueous solution. The influences of initial dye concentration and contact time on the biosorption process were studied. Experimental data were modeled by…

Etude des paramètres influençant la réactivité de bases inorganiques faibles : application à la catalyse hétérogène de transestérification, Study of the parameters governing the reactivity of weak inorganic bases : towards the transesterification reaction

Damien Cornu

Les enjeux actuels pour la valorisation de dérivés de la biomasse donnent à la catalyse hétérogène basique un intérêt nouveau. Dans la mesure où des relations complexes peuvent exister entre la performance d'un catalyseur hétérogène basique et sa force déprotonante, une étude des critères qui…, The current challenges for the valorization of biomass derived products contribute to a growing interest for basic heterogeneous catalysis. Because of the complex connection between the catalytic performance of a basic heterogeneous catalyst and its deprotonating ability, a study of the parameters…
