Rh-Ni/SBA-15 prepared by two solvents method as stable catalysts for the dry reforming of methane at high pressure

M.N. Kaydouh, El Hassan N., Elzakhem H., Anne Davidson, Sandra Casale, Pascale Massiani

The effect of Rh addition on the catalytic performance of Ni/SBA-15 catalysts was studied in the dry reforming of methane. The SBA-15 silica support was synthesized in large quantities and the metals were deposited using the two solvents impregnation method. The properties of the calcined, reduced…

“Water soluble” palladium nanoparticle engineering for C–C coupling, reduction and cyclization catalysis

A. Iben Ayad, C. Belda Marín, E. Colaco, C. Lefevre, C. Methivier, A. Ould Driss, J. Landoulsi, Erwann Guénin

The use of Pd nanoparticles (Pd-NPs) to realize several important organic reactions allows efficient catalysis with low metal loading (<1000 ppm), hence providing a greener catalytic system. However, to be truly green Pd-NPs need to be synthesized in a sustainable manner and be able to react…

Combined fungal and chemical pretreatment of lignocellulosic biomass for biogas production: Effect of pretreatment order and fungal strains

Shruthi Meenakshisundaram, Vincenzo Calcagno, Claire Ceballos, Antoine Fayeulle, Estelle Léonard, Virginie Herledan, Jean-Marc Krafft, Yannick Millot, Xiaojun Liu, Claude Jolivalt, André Pauss

The recalcitrance of lignocellulosic poses a challenge for conversion to biogas and therefore, pretreatment is an essential step in addressing this. Combining fungal pretreatment with a biomimetic system, a mild Fenton reaction, was studied to improve the methane production from straw. The…

Assessing the Oxidation Behavior of EC:DMC Based Electrolyte on Non- Catalytically Active Surface

Iban Azcarate, Wei Yin, Christophe Méthivier, François Ribot, Christel Laberty-Robert, Alexis Grimaud

The race for developing Li-ion batteries positive electrodes with always greater energy density has recently renewed interest towards understanding the formation of the so-called cathode electrolyte interface (CEI) forming upon cycling at high potential. In this work, we used an approach combining…

Temporin-SHa peptides grafted on gold surfaces display antibacterial activity

Andres Lombana, Zahid Raja, Sandra Casale, Claire-Marie Pradier, Thierry Foulon, Ali Ladram, Vincent Humblot

Development of resistant bacteria onto biomaterials is a major problem leading to nosocomial infections. Antimicrobial peptides are good candidates for the generation of antimicrobial surfaces because of their broad-spectrum activity and their original mechanism of action (i.e. rapid lysis of the…

Probing the Orientation of β-Lactoglobulin on Gold Surfaces Modified by Alkyl Thiol Self-Assembled Monolayers

Victor Lebec, Jessem Landoulsi, Souhir Boujday, C. Poleunis, Claire-Marie Pradier, A. Delcorte

The adsorption of a globular protein on chemically well controlled surfaces was investigated in order to correlate its orientation to the surface properties. To this end, three different alkyl thiols, differing by their end group (−COOH, −CH3, and −NH2), were used to build up self-assembled…

Immobilisation of protein A on SAM's for the elaboration of immunosensors

Elisabeth Briand, Michèle Salmain, Chantal Compere, Claire-Marie Pradier

Binary mixtures of 11-mercaptoundecanoic acid (MUA) and other thiols of various lengths and terminal functions were chemisorbed on gold-coated surfaces via S-Au bonds to form mixed self-assembled monolayers (SAMs). Several values of the mole fraction of MUA in the thiol mixtures were tested and the…

Self-Regulating VO2 Photonic Pigments

Maria Letizia de Marco, Olivier Smith, Fanny Thorimbert, Cédric Boissière, Lionel Nicole, Jean-Marc Krafft, Clement Sanchez, Marco Faustini

Nanostructured photonic pigments exhibiting structural colors hold promises to replace conventional pigments for several applications. One emerging challenge in the field consists in integrating additional functionalities to the pigments beyond colors. For instance, integrating phase changing…

Self-Organization and/or Nanocrystallinity of Co Nanocrystals Effects on the Oxidation Process Using High-Energy Electron Beam

Ana Cazacu, Claudio Larosa, Patricia Beaunier, Guillaume Laurent, Paolo Nanni, Liliana Mitoseriu, Isabelle Lisiecki

We report the enhanced stability of Co nanocrystals (NCs) when they are highly ordered at both nanometer and micrometer scales. We show for the first time that both the crystalline structure of Co nanoparticles (NPs) and their 2D hexagonal organization have a significant impact on the oxidation…
