La Recherche en Chimie aux Frontières de la Connaissance

Dominique Massiot, Claire-Marie Pradier, Jacques Maddaluno, Jean-François Tassin, Joël Moreau, Mehran Mostafavi, Anne Imberty, Pascal Breuilles, Catherine Larroche

L’Unité Mixte de Recherche est la brique élémentaire, souple et pérenne d’un paysage de la recherche en évolution rapide. De nombreux dispositifs viennent structurer l’activité de ces équipes pour faire émerger des pôles de recherche, consolider le maillage des réseaux nationaux, identifier les…, Mixed research units are building blocks, flexible but permanent, in rapidly evolving fields of research. Several measures shape the activities of research teams and thus give rise to “poles of research”. They also help consolidate national networks, identify strong points, boost the sharing of top…

In situ XAFS study of the thioresistance of metallic Ru supported on HYd zeolite

Juliette Blanchard, K. Kyoko Bando, Christophe Geantet, Takashi Matsui, Michèle Breysse, Yuji Yoshimura

In situ XAFS at the Ru K edge was used to investigate the reduction of Ru(NH3)63+ supported on HYd zeolite, and the evolution of the reduced sample in the presence of sulfur (350 ppm and 2%H2S/H2) at 523K. After reduction at 673K very small Ru° nanoparticules are formed which interact strongly with…

Preparation of two series of VxSiBeta zeolite catalysts with V centres in framework and extra-framework positions and their application in selective oxidation of methanol

Maciej Trejda, Yannick Millot, Karolina Chalupka, Stanislaw Dzwigaj

Two series of V-containing Beta zeolites have been prepared by contacting of the aqueous NH 4 VO 3 solution with two SiBeta zeolites at pH = 2.5 and 6, respectively. Because of the presence in NH 4 VO 3 solution at pH = 2.5 mainly monomeric VO 2 + ions, vanadium have been easily incorporated into…

Long-Lived Charge-Separated States in ZnS/Na-MOR Zeolite upon <i>trans</i>-Stilbene Adsorption

Pedro Henrique Morais Andrade, Matthieu Hureau, Anne-Sophie Mamede, Pascale Massiani, Alexandre Legrand, Alain Moissette

Electron transfer (ET) processes are of fundamental importance in many photochemical processes in biological and chemical systems. Here, semiconductor nanoparticles of ZnS (as electron relay) and trans-stilbene molecules (t-St) (as electron donor), both confined within the porous volume of…

Influence of the Ageing and Drying Steps of a CoMoP/γ‐Al2O3 Catalyst onto the Multi‐Scale Molybdenum Active Phase Organization

Candice Cottrez, Séverine Humbert, Anne‐sophie Gay, Elodie Devers, Frédéric de Geuser, Xavier Carrier, Alexandra Chaumonnot

To study the influence of ageing and drying steps onto the multiscale Mo active phase arrangement (i. e. MoS2 slabs and slab aggregates), a series of highly loaded CoMoP/γ-Al2O3 catalysts aged, unaged, dried or freeze-dried were prepared and tested in toluene hydrogenation. Electron Probe Micro…

On the use of a constant phase element (CPE) in electrochemistry

Samantha Michelle Gateman, Oumaïma Gharbi, Hercílio Gomes De Melo, Kieu Ngo, Mirelle Turmine, Vincent Vivier

Several techniques can be used to experimentally determine the interfacial capacitance of an electrode, which is a crucial parameter used for quantifying the efficiency of supercapacitors. However, the values obtained from cyclic voltammetry can be significantly different from those extracted from…

Boosting CO2 reforming of methane via the metal-support interaction in mesostructured SBA-16-derived Ni nanoparticles

Chao Sun, Paulina Summa, Ye Wang, Katarzyna Świrk, Albert Miró I Rovira, Sandra Casale, Konrad Świerczek, Changwei Hu, Magnus Rønning, Patrick da Costa

High surface area and porosity SBA-16 was synthesized and used as support for Ni nanoparticles using three methods including wet impregnation, citric acid-assisted impregnation, and ammonia evaporation. All the studied samples showed high activity in the CO2 reforming of methane reaction, however,…

Quantifying Cell Traction Forces at the Individual Fiber Scale in 3D: A Novel Approach Based on Deformable Photopolymerized Fiber Arrays

Pierre Ucla, Joanne Le Chesnais, Henri Ver Hulst, Xingming Ju, Isabel Calvente, Ludovic Leconte, Jean Salamero, Isabelle Bonnet, Catherine Monnot, Hélène Moreau, Jessem Landoulsi, Vincent Semetey, Sylvie Coscoy

The forces exerted by cells upon the fibers of the extracellular matrix play a decisive role in cell motility in development and disease. How the local physical properties of the matrix (such as density, stiffness, orientation) affect cellular forces remains poorly understood. Existing approaches…

Immobilization of polyoxometalate hybrid catalysts onto mesoporous silica supports using phenylene diisothiocyanate as a cross-linking agent

Ourania Makrygenni, Dalil Brouri, Anna Proust, Franck Launay, Richard Villanneau

The hybrid derivative of heteropolytungstate bearing two aniline groups, namely (nBu4N)3[NaHPW9O34{As(O)C6H4NH2}2], was post-functionalized in the presence of 1,4-phenylene diisothiocyanate (PDITC). The resulting molecular moiety was characterized by IR, 1H and 31P NMR spectroscopy. In a second…
