Proving ligand structure-reactivity correlation on multinuclear copper electrocatalysts supported on carbon black for the oxygen reduction reaction

Ricardo Venegas, Karina Muñoz-Becerra, Sophie Juillard, Lin Zhang, Rubén Oñate, Ingrid Ponce, Vincent Vivier, Francisco J Recio, Carlos M Sánchez-Sánchez

Bioinspired transition-metal catalysts seek to mimic the specific active site of metalloenzymes, as the multicopper oxidase, that can efficiently reduce dioxygen to water via a complete 4-electrons mechanism at low overpotential. However, the multicopper oxidase enzymes lack stability under…

Approach for Plasmonic Based DNA Sensing: Amplification of the Wavelength Shift and Simultaneous Detection of the Plasmon Modes of Gold Nanostructures

Jolanda Spadavecchia, Alexandre Barras, Joël Lyskawa, Patrice Woisel, William Laure, Claire-Marie Pradier, Rabah Boukherroub, Sabine Szunerits

In this article, the detection of DNA hybridization taking advantage of the plasmonic properties of gold nanostructures is described. The approach is based on the amplification of the wavelength shift of a multilayered localized surface plasmon resonance (LSPR) sensor interface upon hybridization…

Synthesis and characterization of Ag-Protoporphyrin nano structures using mixed co-polymer method

Ramesh Perumal, Sandra Casale, Luca de Stefano, Jolanda Spadavecchia

In this paper, we report the synthesis of hybrid silver nanostructures (AgNPs) based on an effective mixing of polyols with Polyvinylpyrrolidone (PVP) and Porphyrin molecules, in particular Protoporphyrin IX (PP). The combination of PVP and PP, which act as co-directing agents and favour the…

Impregnation of .gamma.-Alumina with Ni(II) or Co(II) Ions at Neutral pH: Hydrotalcite-Type Coprecipitate Formation and Characterization

Jean-Baptiste d'Espinose de la Caillerie, Maggy Kermarec, Olivier Clause

The adsorption of Co(II) or Ni(II) ammine complexes from aqueous solutions onto y-alumina at neutral or near neutral pH (7 < pH < 8.2) and ambient temperature is investigated as a function of the ion concentration in the impregnating solutions, the contact and aging times, and the drying…

Tuning the load in gold and magnetic nanoparticles in nanogels through their design for enhanced dual magneto-photo-thermia

Esther Cazares-Cortes, Claire Wilhelm, Jose Efrain Perez, Ana Espinosa, Sandra Casale, Aude Michel, Ali Abou-Hassan, Christine Ménager

We describe a novel synthesis allowing to enhance the load in magnetic nanoparticles and gold nanorods in nanogels. Two different structures, simple cores and core-shells were synthesized and their heating properties upon alternating magnetic field or laser exposure are compared. Remarkably, the…

Activity of molybdenum and tungsten oxycarbides in hydrodenitrogenation of carbazole leading to isomerization secondary reaction of bicyclohexyl. Results using bicyclohexyl as feedstock

Marek Lewandowski, Agnieszka Szymańska-Kolasa, Céline Sayag, Gérald Djéga-Mariadassou

The catalytic activities of bulk tungsten and molybdenum oxycarbides, (W2C and Mo2C) have been specifically studied in the isomerization occurring during the hydrodenitrogenation (HDN) of carbazole. The two catalysts have been characterized by several physico-chemical techniques such as X-Ray…

The optimal heterogeneous catalyst for an acid-base reaction

Hervé Toulhoat

Different iron species exhibit distinct activity and selectivity in CO2 hydrogenation reaction. Herein, by controlling calcination temperature, Fe-Al interaction in Na promoted Fe-Al catalysts has been regulated, which further leads to various compositions of iron oxide (FeOx) and iron carbides (…

Flavonols and 3-hydroxychromones: new applications for a class of environment-sensitive fluorescent molecules

Stefano Protti, Alberto Mezzetti

Flavonols are naturally-occuring molecules that exhibit interesting fluorescence properties. Thanks to an excited-state intramolecular proton transfer, to specific interactions with their molecular environment and to ground-state proton transfer reactions, very often a dual or even triple…
