Gold Nanorods for LSPR Biosensing: Synthesis, Coating by Silica, and Bioanalytical Applications

Vincent Pellas, David Hu, Yacine Mazouzi, Yoan Mimoun, Juliette Blanchard, Clément Guibert, Michèle Salmain, Souhir Boujday

Nanoparticles made of coinage metals are well known to display unique optical properties stemming from the localized surface plasmon resonance (LSPR) phenomenon, allowing their use as transducers in various biosensing configurations. While most of the reports initially dealt with spherical gold…

Covalent immobilization of glucose oxidase on mesocellular silica foams: Characterization and stability towards temperature and organic solvents

Noemie Balistreri, Dorian Gaboriau, Claude Jolivalt, Franck Launay

Glucose oxidase (GOx) immobilization onto mesoporous SBA-15 silica and two mesocellular foams (MCF) characterized by similar surface area and pore volumes but different pore/cell dimensions was examined. The covalent grafting of the enzyme through amide bonds was evidenced by controlling pH…

Giant Exchange-Bias in Polyol-Made CoFe2O4-CoO Core-Shell Like Nanoparticles

Nancy Flores-Martinez, Giulia Franceschin, Thomas Gaudisson, Patricia Beaunier, Nader Yaacoub, Jean-Marc Greneche, Raul Valenzuela, Souad Ammar

Cobalt ferrite ferrimagnetic nanoparticles (NPs) are prepared and used in this work as seeds to grow a thin antiferromagnetic poly- and nanocrystalline CoO shell. The major purpose is to study systematically the characteristics of the as-produced powders, making emphasis on their internal…

Identification of the silver state in the framework of Ag-containing zeolite by XRD, FTIR, photoluminescence, 109 Ag NMR, EPR, DR UV-vis, TEM and XPS investigations

Nataliia Popovych, Pavlo Kyriienko, Sergiy Soloviev, Rafal Baran, Yannick Millot, Stanislaw Dzwigaj

Silver has been identified in the framework of AgxSiBEA zeolites (where x = 3–6 Ag wt%) by the combined use of XRD, 109Ag MAS NMR, FTIR, diffuse reflectance UV-visible, EPR and XPS spectroscopy. The incorporation of Ag ions into the framework of SiBEA zeolite has been evidenced by XRD. The…

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…

Ruthenium sulfide clusters in acidic zeolites: in situ XAS characterization during sulfidation and reaction

Juliette Blanchard, Kyoko K. Bando, Takashi Matsui, Masaru Harada, Michèle Breysse, Yuji Yoshimura

In situ XAS at the Ru K edge was used to study the reductive sulfidation (15% H2S/H2) of Ru(NH3)63+ supported on HYd zeolite, and the evolution of the sulfided sample under working conditions (lower H2S partial pressure, addition of toluene to the feed). Sulfidation starts at room temperature and…

Acidity versus metal-induced Lewis acidity in zeolites for Friedel–Crafts acylation

Claire Bernardon, Manel Ben Osman, Guillaume Laugel, Benoît Louis, Patrick Pale

Acid catalysts including Ni, Ag and Fe-loaded zeolites of different structures were prepared either via cationic exchange or impregnation techniques from pristine H-zeolites (BEA, and MFI). Their catalytic activity was evaluated in the liquid-phase Friedel–Crafts acylation of anisole with propanoic…, Des cations métalliques (Ni, Ag et Fe) ont été incorporés au sein de zéolithes BEA et ZSM-5 par des techniques d'échange cationique et d'imprégnation afin d'obtenir de nouveaux catalyseurs acides solides. Ces matériaux ont ensuite été testés dans une réaction d'acylation de…
