True Circular Dichroism in Optically Active Achiral Metasurfaces and Its Relation to Chiral Near-Fields

Mathieu Nicolas, Per Magnus Walmsness, Jayeeta Amboli, Lu Zhang, Guillaume Demesy, Nicolas Bonod, Souhir Boujday, Morten Kildemo, Bruno Gallas

Optically active achiral metasurfaces offer a promising way to detect chiral molecules based on chiroptic methods. The combination of plasmonic enhanced circular dichroism and reversible optical activity would boost the sensitivity and provide enantiomerselective surfaces while using a single…

Elaboration de catalyseurs hétérogènes en milieu liquide ionique : nanoparticules métalliques (Au et Au-Pd) supportées sur dioxyde de titane, Heterogeneous catalysts preparation in ionic liquid media : titania-supported metallic nanoparticles (Au and Au-Pd)

Camella Oumahi

Ces travaux portent sur l'élaboration de catalyseurs hétérogènes en milieu liquide ionique (LI). Ces sels liquides à température ambiante permettent d'ajuster les propriétés du solvant suivant la composition chimique du LI mis en jeu (sels d'imidazolium ou Deep Eutectic Solvent à…, This work deals with the elaboration of heterogeneous catalysts in ionic liquids (ILs). These salts, liquid at room temperature, were chosen because they permit to adjust the solvent properties depending on their chemical composition (imidazolium salts or Deep Eutectic Solvent based on choline…

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…

Platinum-zeolite hybrid catalyst for the electrooxidation of formic acid

Lu Zhang, Juan V Perales-Rondón, Angélica Thomère, Juliette Blanchard, Carlos M Sánchez-Sánchez

Formic acid oxidation reaction (FAOR) was studied using different platinum-zeolites hybrid catalysts. The catalysts were prepared by addition of two different forms of the ZSM-5 zeolite (ZSM-5-H+ and ZSM-5-NH4+) to an ink containing Vulcan carbon support and Pt nanoparticles (NPs). TEM images…
