In the context of nanomedicine, liposils (liposomes and silica) have a strong potential for drug storage and release schemes: such materials combine the intrinsic properties of liposome (encapsulation) and silica (increased rigidity, protective coating, pH degradability). In this work, an original…

Chiral self-assemblies of amino-acid molecules: D- and L-methionine on Au(111) surface

Ahmed Naitabdi, Vincent Humblot

Spontaneous self-assembly into chiral well-ordered two-dimensional molecular film at room temperature has been evidenced using the scanning tunneling microscopy for the growth of two enantiomerically pure L- and D-methionine on Au(111) surface. From the x-ray photoelectron spectroscopy measurements…

Factors impacting protein adsorption on layer-by-layer assembled stimuli-responsive thin films

A. Osypova, C.-A. Fustin, C.-M. Pradier, Jessem Landoulsi, S. Demoustier-Champagne

Studying the stimuli-response of polyelectrolyte multilayers (PEMs) towards protein adsorption requires coping with the multiplicity of factors influencing interfacial processes. In this study, we report the design of a nanostructured stimuli-responsive coating based on the sequential layer-by…

Ethylene production from diluted bioethanol solutions

Ilenia Rossetti, Matteo Compagnoni, Giorgia de Guido, Laura A. Pellegrini, Gianguido Ramis, Stanislaw Dzwigaj

Ethylene production by ethanol dehydration has been investigated over a set of zeolites with BEA structure in acidic form (HAlBEA). The effect on Ni addition (up to 0.03 g/g (3 mass%)) is explored as a means to improve ethylene selectivity limiting the formation of heavier byproducts. The reaction…

Phase selective synthesis of nickel silicide nanocrystals in molten salts for electrocatalysis of the oxygen evolution reaction

Ram Kumar, Mounib Bahri, Yang Song, Francisco Gonell, Cyril Thomas, Ovidiu Ersen, Clément Sanchez, Christel Laberty-Robert, David Portehault

We report phase selective synthesis of intermetallic nickel silicide nanocrystals in inorganic molten salts. NiSi and Ni2Si nanocrystals are obtained by reacting a nickel (II) salt and sodium silicide Na4Si4 in the molten LiI-KI inorganic eutectic salt mixture. We report that nickel silicide…

Speciation of Ruthenium as a Reduction Promoter of Silica-Supported Co Catalysts: A Time-Resolved in Situ XAS Investigation

Jingping Hong, Eric Marceau, Andrei Y. Khodakov, Lucia Gaberová, Anne Griboval-Constant, Jean-Sébastien Girardon, Camille La Fontaine, Valérie Briois

Complete reduction of the metal phase in cobalt-containing catalysts is often difficult to reach and can be promoted by a small amount of noble metals. Because these costly promoters are introduced in a very low quantity, their speciation and their chemical interaction with cobalt have seldom been…

Nouvelles biocathodes graphite/nitrure de carbone amorphe/laccase pour la réduction de l'oxygène par transfert électronique direct

Achraft Blout, Alain Pailleret, Hubert Perrot, Claude Jolivalt

Les enzymes constituent une alternative intéressante aux catalyseurs métalliques car elles possèdent une meilleure sélectivité et des performances catalytiques souvent plus élevées. Elles peuvent être utilisées dans différents types de dispositifs électrochimiques comme les piles à combustible1.…

Influence of Metal Salts Addition on Physical and Electrochemical Properties of Ethyl and Propylammonium Nitrate

David Ausín, José Trenzado, Mireille Turmine, Luis Varela, Oscar Cabeza, Elisa González Romero, Luisa Segade

In this work, we deepen in the characterization of two protic ionic liquids (PILs), ethylammonium nitrate (EAN) and propylammonium nitrate (PAN). With this aim, we determined the influence of inorganic nitrate salts addition on their physical properties and their electrochemical potential window (…

Catalytic behavior of copper–amine complex supported on mesoporous silica SBA-15 toward mono-Aza-Michael addition: role of amine groups

Aboubakr Hakiki, Riad Mustpha Kerbadou, Bouhadjar Boukoussa, Hadjira Habib Zahmani, Franck Launay, Alain Pailleret, Françoise Pillier, Salih Hacini, Abdelkader Bengueddach, Rachida Hamacha

This work concerns the preparation and modification of mesoporous silica SBA-15 with different amine-copper complexes in order to study their impact on the catalytic behavior via Aza Michael addition. Firstly, SBA-15 was prepared hydrothermally, then functionalized by mono-, di- and tri-amine, and…
