“Water soluble” palladium nanoparticle engineering for C–C coupling, reduction and cyclization catalysis

A. Iben Ayad, C. Belda Marín, E. Colaco, C. Lefevre, C. Methivier, A. Ould Driss, J. Landoulsi, Erwann Guénin

The use of Pd nanoparticles (Pd-NPs) to realize several important organic reactions allows efficient catalysis with low metal loading (<1000 ppm), hence providing a greener catalytic system. However, to be truly green Pd-NPs need to be synthesized in a sustainable manner and be able to react…

Combined fungal and chemical pretreatment of lignocellulosic biomass for biogas production: Effect of pretreatment order and fungal strains

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

The recalcitrance of lignocellulosic poses a challenge for conversion to biogas and therefore, pretreatment is an essential step in addressing this. Combining fungal pretreatment with a biomimetic system, a mild Fenton reaction, was studied to improve the methane production from straw. The…

Effect of postsynthesis preparation procedure on the state of copper in CuBEA zeolites and its catalytic properties in SCR of NO with NH3

Rafal Baran, Frederic Averseng, Dominik Wierzbicki, Karolina Chalupka, Jean-Marc Krafft, Teresa Grzybek, Stanislaw Dzwigaj

Copper-containing BEA zeolites, Cu2.0SiBEA and Cu2.0HAlBEA, with 2 wt % of Cu were prepared by a two-step postsynthesis method and a conventional wet impregnation, respectively. These zeolites were characterized by XRD, DR UV–vis, EPR, FTIR and TPR physicochemical techniques. The incorporation of…

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…

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…

Probing the Orientation of β-Lactoglobulin on Gold Surfaces Modified by Alkyl Thiol Self-Assembled Monolayers

Victor Lebec, Jessem Landoulsi, Souhir Boujday, C. Poleunis, Claire-Marie Pradier, A. Delcorte

The adsorption of a globular protein on chemically well controlled surfaces was investigated in order to correlate its orientation to the surface properties. To this end, three different alkyl thiols, differing by their end group (−COOH, −CH3, and −NH2), were used to build up self-assembled…

Immobilisation of protein A on SAM's for the elaboration of immunosensors

Elisabeth Briand, Michèle Salmain, Chantal Compere, Claire-Marie Pradier

Binary mixtures of 11-mercaptoundecanoic acid (MUA) and other thiols of various lengths and terminal functions were chemisorbed on gold-coated surfaces via S-Au bonds to form mixed self-assembled monolayers (SAMs). Several values of the mole fraction of MUA in the thiol mixtures were tested and the…
