On the relationship between the basicity of a surface and its ability to catalyze transesterification in liquid and gas phases: the case of MgO

Damien Cornu, Hazar Guesmi, Guillaume Laugel, Jean-Marc Krafft, Hélène Lauron-Pernot

Gas or liquid phase transesterification reactions are used in the field of biomass valorization to transform some platform molecules into valuable products. Basic heterogeneous catalysts are often claimed for these applications but the role of basicity in the reaction mechanism depending on the…

Static and dynamic electronic characterization of organic monolayers grafted on a silicon surface

Olivier Pluchery, Y. Zhang, R. Benbalagh, L. Caillard, J. J. Gallet, F. Bournel, A.-F. Lamic-Humblot, M. Salmeron, Y. J. Chabal, F. Rochet

Organic layers chemically grafted on silicon offer excellent interfaces that may open up the way for new organic–inorganic hybrid nanoelectronic devices. However, technological achievements rely on the precise electronic characterization of such organic layers. We have prepared ordered grafted…

Critical assessment of solvent effects on absorption and fluorescence of 3HF in acetonitrile in the QM/PCM framework: A synergic computational and experimental study

Daniele Loco, Stefano Protti, Benedetta Mennucci, Alberto Mezzetti

Absorption and fluorescence properties of 3-hydroxyflavone (3HF) dissolved in the polar aprotic solvent acetonitrile have been investigated by electronic spectroscopies, associated to mixed quantum mechanical (QM)/classical calculations, where the effect of the solvent is included at the classical…

Cation Migration and Structural Deformations upon Dehydration of Nickel-Exchanged NaY Zeolite: A Combined Neutron Diffraction and Monte Carlo Study

Wilfried Louisfrema, Jean-Louis Paillaud, Florence Porcher, Elsa Perrin, Thomas Onfroy, Pascale Massiani, Anne Boutin, Benjamin Rotenberg

Combining neutron diffraction and classical molecular simulations, we describe the cation migration and associated structural changes taking place in a Ni-exchanged NaY faujasite zeolite upon stepwise dehydration from room temperature up to 400 °C. The cation redistribution between sites and the…

Co-grafting of antiadhesive and antimicrobial agents onto UV-micropatterned copper surfaces

Jessie Peyre, Vincent Humblot, Christophe Méthivier, Jean-Marc Berjeaud, Claire-Marie Pradier

Adhesion of proteins and bacteria was reduced by a factor close to one order of magnitude, and adhered bacteria were dramatically damaged on copper surfaces by grafting a PEG-modified PMMA-based (polymethyl methacrylate) copolymer together with an antimicrobial peptide. To obtain PEG and a peptide…

Potent antimicrobial peptides against Legionella pneumophila and its environmental host, Acanthamoeba castellanii.

Margot Schlusselhuber, Vincent Humblot, Sandra Casale, Christophe Méthivier, Julien Verdon, Matthias Leippe, Jean-Marc Berjeaud

Legionella pneumophila, the major causative agent of Legionnaires' disease, is most often found in the environment in close association with free-living amoebae, leading to persistence, spread, biocide resistance, and elevated virulence of the bacterium. In the present study, we evaluated the…

Biomass characterization and biogas production of pretreated straw: is there a correlation?

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

Lignocellulosic biomass is a very attractive substrate for biogas production via anaerobic digestion. Among all, straw represents a very interesting and worldwide diffused agricultural by-product. However, due to the intrinsically complex structure of lignocellulosic biomass, straw has low…

Design of TiO2/Au nanoparticle films with controlled crack formation and different architectures using a centrifugal strategy

Abdelhafed Taleb, Frederic Mesguich, Thomas Onfroy, Xue Yanpeng

Here we present an approach to design hybrid nanocomposite films based on TiO2/Au nanoparticles using centrifugation processes. The prepared nanocomposite films have been characterized by different techniques such as FEGSEM, TEM, BET and XRD. Furthermore it is demonstrated that centrifugal force…
