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…

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…

Molten Salts‐Driven Discovery of a Polar Mixed‐Anion 3D framework at the nanoscale: Zn4Si2O7Cl2, Charge Transport and Photoelectrocatalytic Water Splitting

Ram Kumar, Yang Song, Anissa Ghoridi, Philippe Boullay, Gwenaelle Rousse, Christel Gervais, Cristina Coelho Diogo, Houria Kabbour, Capucine Sassoye, Patricia Beaunier, Victor Castaing, Bruno Viana, Maria Luisa Ruiz Gonzalez, José Gonzalez Calbet, Christel Laberty-Robert, David Portehault

Mixed-anion compounds widen the chemical space of attainable materials compared to single anionic compounds, but the exploration of their structural diversity is limited by common synthetic paths. Especially, oxychlorides rely mainly on layered structures, which suffer from low stability during…
