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…

Unraveling the Mechanisms of Hypertrophy-Induced Matrix Mineralization and Modifications in Articular Chondrocytes

Ilhem Lilia Jaabar, Brittany Foley, Alberto Mezzetti, Françoise Pillier, Francis Berenbaum, Jessem Landoulsi, Xavier Houard

Chondrocyte hypertrophic differentiation is a main event leading to articular cartilage degradation in osteoarthritis. It is associated with matrix remodeling and mineralization, the dynamics of which is not well characterized during chondrocyte hypertrophic differentiation in articular cartilage.…

Fine-tuning protocols for accurate study of nanoparticle adhesion and uptake after foliar deposition

Mickael Wagner, Ilan Minerva, Aude Calas, Fadoua Sallem, Françoise Maubé, Camille Larue, Astrid Avellan

<div><p>Understanding interactions between plant leaves and nanoparticles (NPs) is crucial for advancing both and environmental and the safety of plant protection products. Recent studies showed how the fate of NPs on leaf surfaces is influenced by NP properties, plant surface, and…

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…

Heterogeneous catalyst preparation in ionic liquids: Titania supported gold nanoparticles

Camella Oumahi, Jean Lombard, Sandra Casale, Christophe Calers, Laurent Delannoy, Catherine Louis, Xavier Carrier

This work reports the use of ionic liquids (ILs) as solvent for the synthesis of Au/TiO2 heterogeneous catalysts. It is shown that the versatility of the physico-chemical properties of ILs makes them interesting solvents for a broad control of supported metal nanoparticles (NPs) size and for a fine…

Tuning Model Drug Release and Soft-Tissue Bioadhesion of Polyester Films by Plasma Post-Treatment

Vishal T. Mogal, Chaw Su Yin, Richard O’rorke, Souhir Boujday, Christophe Méthivier, Subbu S. Venkatraman, Terry W. J. Steele

lasma treatments are investigated as a post-production method of tuning drug release and bioadhesion of poly(lactic-co-glycolic acid) (PLGA) thin films. PLGA films were treated under varying conditions by controlling gas flow rate, composition, treatment time, and radio frequency (RF) power. In…

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…

Cu-modified hydroxy-apatite as catalyst for Glaser–Hay CC homo- coupling reaction of terminal alkynes

Birgit Maaten, Jamal Moussa, Christophe Desmarets, Patrick Gredin, Patricia Beaunier, Tõnis Kanger, Kaia Tõnsuaadu, Didier Villemin, Michel Gruselle

The oxidative Glaser–Hay coupling reaction of terminal alkynes is a very important reaction in organic chemistry to achieve the synthesis of diyne compounds. In general the reaction is performed under homogeneous conditions using Cu(I) or Cu(II) salts in the presence of a reagent such as…
