Porosity Design of Shaped Zeolites for Improved Catalyst Lifetime in the Methanol-to-Hydrocarbons Reaction

Rogéria Bingre, Renna Li, Qiang Wang, Patrick Nguyen, Thomas Onfroy, Benoit Louis

Additional porosity, such as meso-and macropores, was introduced in zeolite extrudates with the intention intuit of improving the effective diffusivity of the catalysts. The samples were characterized in depth by nitrogen adsorption-desorption, mercury intrusion porosimetry, ammonia temperature…

Surface passivation of aluminum alloy 6061 with gaseous trichlorosilane: A surface investigation

Rickielle Ngongang, Eric Marceau, Xavier Carrier, Claire-Marie Pradier, Christophe Méthivier, Jean-Luc Blanc, Martine Carré

A molecular-scale investigation of the interaction at room temperature between gaseous trichlorosilane (HSiCl3), used as a passivating agent, and surfaces of aluminum alloy AA6061 in a polished or hydroxylated state is conducted. Atomic force microscopy (AFM) and scanning electron microscopy (SEM)…

Development of a thermodynamic approach to assist the control of the precipitation of hydroxyapatites and associated calcium phosphates in open systems

Corentin Reynaud, Cyril Thomas, Sandra Casale, Sophie Nowak, Guylène Costentin

The understanding of the precipitation mechanisms of calcium phosphates (CaPs) remains extremely challenging despite its fundamental interest for material sciences and its practical implications in medicine, paleosciences, and chemistry, especially for heterogeneous catalysis. The competitive…

Impregnation of .gamma.-Alumina with Ni(II) or Co(II) Ions at Neutral pH: Hydrotalcite-Type Coprecipitate Formation and Characterization

Jean-Baptiste d'Espinose de la Caillerie, Maggy Kermarec, Olivier Clause

The adsorption of Co(II) or Ni(II) ammine complexes from aqueous solutions onto y-alumina at neutral or near neutral pH (7 < pH < 8.2) and ambient temperature is investigated as a function of the ion concentration in the impregnating solutions, the contact and aging times, and the drying…

Fate of Organic Molecules in the Mars Regolith Under UV Radiation Deduced from the MOMIE Laboratory Experiment

Cyril Szopa, Patrice Coll, Fabien Stalport, Olivier Poch, Maguy Jaber, Jean-François Lambert, Laura Rouquette, Jérôme Lasne

Among bioindicators or biosigna- tures, organic molecules present on Mars could be re- trieved in the regolith near the surface due to erosion of rocks and gardening of the soil from meteorites bom- bardment through the Mars history. Once their, the organic molecules are submitted to the harsh…

Equilibrium and dynamics of single-peptide binding to aluminum oxides: Emphasizing the role of local surface charge and hydrophobicity

Joanne Lê-Chesnais, Christophe Méthivier, Daniela Rodriguez, Christophe Humbert, Jean-François Lambert, Jessem Landoulsi

Understanding the interactions between biomolecules and mineral surfaces is a fundamental challenge at the crossroads of colloid science, surface chemistry, and molecular biophysics. While peptides and amino acids are known to bind a variety of metal oxides, our understanding remains limited…

From 8-hydroxy-5-sulfoquinoline to new related fluorogenic ligands for complexation of aluminium(III) and gallium(III)

Franck Launay, Valérie Alain-Rizzo, Émilie Destandau, Nathalie Ramos, Ēlisabeth Bardez, Paul Baret, Jean-Louis Pierre

The hexadentate tripodal ligand O-TRENSOX (already known as a siderophore), incorporating three 8-hydroxy-5- sulfoquinoline (8-HQS) subunits, was investigated as a potential Ñuorogenic ligand of Al(III) and Ga(III). For the sake of comparison, every chelation study was also carried out with n-BUSOX…

Covalent Grafting of Organic–Inorganic Polyoxometalates Hybrids onto Mesoporous SBA-15: A Key Step for New Anchored Homogeneous Catalysts

Richard Villanneau, Asma Marzouk, Yan Wang, Aicha Ben Djamaa, Guillaume Laugel, Anna Proust, Franck Launay

Covalent grafting of the polyoxometalate (POM) hybrid [AsW9O33{P(O)(CH2CH2CO2H)}2]5- on mesoporous NH2-functionalized SBA-15 is the first example of anchored vacant POMs in which nucleophilic oxygen atoms are still available after incorporation into the supports. Such systems are interesting…

Loop-stabilized BAB triblock copolymer morphologies by PISA in water

Pauline Biais, Patricia Beaunier, François Stoffelbach, Jutta Rieger

A straightforward strategy to synthesize in water, loop-stabilized particles via PISA is developed. These particular structures can in theory be obtained through the synthesis of amphiphilic BAB triblock copolymers, starting from a hydrophilic middle block A, which is chain extended in an aqueous…
