In-situ monitoring of transition metal complex adsorption on oxide surfaces during the first stages of supported metal catalyst preparation

Juliette Blanchard, Antoine Hervier, Guylène Costentin, John Regalbuto, Catherine Louis, Souhir Boujday

In the preparation of supported catalysts by deposition, in solution, of a transition metal complex (TMC) on an oxide support, the interactions occurring at the solid/liquid interface between the TMC and the oxide have a crucial impact on the properties of the final catalyst. However, these…

Partial oxidation of methane over bifunctional catalyst I. In situ formation of Ni0/La2O3 during temperature programmed POM reaction over LaNiO3 perovskite

Tri Huu Nguyen, Agata Łamacz, Patricia Beaunier, Sylwia Czajkowska, Marian Domański, Andrzej Krztoń, Tiep van Le, Gérald Djéga-Mariadassou

The transformation of perovskite to an oxide-supported metal during reaction of partial oxidation of methane (POM) has been very often cited in literature as the “reduction” of the perovskite, without any detailed mechanism. In this work, the in situ transformation of initial LaNiO3 perovskite to…

Building of an immunosensor : how can the composition and structure of the thiol attachment layer affect the immunosensor efficiency ?

Elisabeth Briand, Michèle Salmain, Jean-Marie Herry, Hubert Perrot, Chantal Compere, Claire-Marie Pradier

Immunosensors, based on the immobilsation of model rabbit antibodies on a mixed self assembled monolyaers and Protein A as a linking agent on gold transducers, were elaborated and characterised at each step by Modulated polarisation- Infrared Spectroscopy (PM-IRRAS) and punctually by Atomic Force…

In situ photo-electrochemical investigation using surface X-ray diffraction: from ultra-high vacuum to solid/electrolyte interfaces

Axel Wilson, I M Nadeem, H Hussain, X Torrelles, J Imran, D Garai, Robert Lindsay, Gregory Cabailh, J Zegenhagen, G Thornton, C Nicklin

<div><p>A Photo-ElectroChemical DrOplet Cell (PEC-DOC) has been developed for the I07 surface diffraction beamline of Diamond Light Source to investigate solid-liquid interfaces using Surface X-Ray Diffraction (SXRD). PEC-DOC is ultrahigh vacuum (UHV) compatible, and so can be directly…

Effect of the niobium state on the properties of NbSiBEA as bifunctional catalysts for gas- and liquid-phase tandem processes

Pavlo I. Kyriienko, Olga V. Larina, Nataliia O. Popovych, Sergiy O. Soloviev, Yannick Millot, Stanislaw Dzwigaj

NbSiBEA zeolites contained isolated framework mononuclear Nb(V) (Nb0.7SiBEA) and a mixture of framework mononuclear and extra-framework polynuclear Nb(V) (Nb2.0SiBEA) were prepared by two-step postsynthesis method as evidenced by XRD, NMR, DR UV–vis and FTIR. DR UV–vis showed that two types of…

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…

Investigation of the collapse of bubbles after the impact of a piston on a liquid free surface

Maya Mounir Daou, Elena Igualada, Hugo Dutilleul, Jean-Marie Citerne, Javier Rodríguez-Rodríguez, Stéphane Zaleski, Daniel Fuster

A novel technique based on the impact of a piston on a liquid confined in a vessel is described. Pressure measurements reveal that strong pressure variations (up to 100 atmospheres) with a rich content of frequencies are efficiently transmitted to the liquid. High-speed camera visualizations show…
