Ordered mesoporous “one-pot” synthesized Ni-Mg(Ca)-Al2O3 as effective and remarkably stable catalysts for combined steam and dry reforming of methane (CSDRM)

Karam Jabbour, Pascale Massiani, Anne Davidson, Sandra Casale, Nissrine El Hassan

Two series of Nix% (x: 5–10 wt%) and Ni5%M5% (M: Ca or Mg) containing mesoporous Al2O3 catalysts were prepared by “one-pot” synthesis following an evaporation-induced self-assembly (EISA) method. After reduction, the catalysts showed very high Ni dispersion within the structured oxide matrix giving…

Acidic Osteoid Templates the Plywood Structure of Bone Tissue

Marc Robin, Chakib Djediat, Arnaud Bardouil, Niki Baccile, Camille Chareyron, Ivo Zizak, Peter Fratzl, Mohamed Selmane, Bernard Haye, Isabelle Genois, Jean‐marc Krafft, Guylène Costentin, Thierry Azaïs, Franck Artzner, Marie‐madeleine Giraud-Guille, Paul Zaslansky, Nadine Nassif

Bone is created by osteoblasts that secrete osteoid after which an ordered texture emerges, followed by mineralization. Plywood geometries are a hallmark of many trabecular and cortical bones, yet the origin of this texturing in vivo has never been shown. Nevertheless, extensive in vitro work…

Catalytic activity and thermostability of enzymes immobilized on silanized surface: Influence of the crosslinking agent

Nesrine Aissaoui, Jessem Landoulsi, Latifa Bergaoui, Souhir Boujday, Jean-François Lambert

In this work, we investigate the influence of crosslinkers on the operational and heat stability of immobilized enzymes on a silanized silicon surface. To this end, glucose-6-phosphate dehydrogenase (G6PDH), a model multimeric enzyme, was attached through bifunctional crosslinkers able to bind…

Electrochemical deposition of ZnO thin films in aprotic ionic liquids: Effect of the cationic alkyl-chain-length

Rita Khalil, Mirella Azar, Ibrahim Bou Malham, Mireille Turmine, Vincent Vivier

Zinc oxide (ZnO) is a semiconductor with various physicochemical properties allowing its use in a wide range of technological applications. The aim of this work is to study nanocrystalline ZnO thin-film deposited using zinc salt which is dissolved in pure ionic liquids (ILs). The latter play a dual…

Direct grafting of ethylene sulfide onto silicic acid magadiite

Michelle Menezes de Oliveira, Marcia Maria Fernandes, Maria Gardennia Fonseca, Edson Cavalcanti da Silva Filho, Antonio Gouveia de Souza, Fabrice Gaslain, Maguy Jaber

Acidic magadiite (HMag) was directly reacted with ethylene sulfide (ES) under various controlled conditions producing an intercalated hybrid silicate (MagS). The sodium, acidic and modified magadiites were characterized using elemental analysis, thermogravimetric analysis (TGA/DTG), infrared…

Conversion of xylene over mordenites: an operando infrared spectroscopy study of the effect of Na+

Pascale Massiani, Olivier Marie, Frédéric Thibault-Starzyk

A series of progressively proton-exchanged sodium mordenite samples was studied by operando infrared spectroscopy during xylene conversion. This unique, powerful tool allowed us to characterize the species adsorbed to the surface during catalysis and to follow the evolution of the active sites as…

Engineering of Antimicrobial Surfaces by Using Temporin Analogs to Tune the Biocidal/antiadhesive Effect

Pierre-Carl Oger, Christophe Piesse, Ali Ladram, Vincent Humblot

Proliferation of resistant bacteria on biomaterials is a major problem leading to nosocomial infections. Due to their broad-spectrum activity and their ability to disrupt bacterial membranes through a rapid membranolytic mechanism, antimicrobial peptides (AMPs) are less susceptible to the…
