Identification of Surface Basic Sites and Acid–Base Pairs of Hydroxyapatite

Sarah Diallo-Garcia, Manel Ben Osman, Jean-Marc Krafft, Sandra Casale, Cyril Thomas, Jun Kubo, Guylène Costentin

The Lewis and Brønsted basic properties of a stoichiometric hydroxyapatite (HAp) were investigated by infrared spectroscopy following the adsorption and desorption processes of a Lewis acidic molecule, CO2, and a Brønsted acidic molecule, C2H2. CO2 interacts with basic OH– and O2– of PO43– groups…

Amplified plasmonic detection of DNA hybridization using doxorubicin-capped gold particles

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

We show in this article that doxorubicin-modified gold nanoparticles (Au NP-DOX) can be used for the post-amplification of the wavelength shift of localized surface plasmon resonance (LSPR) signals after DNA hybridization events. We take advantage of the intercalation properties of DOX with guanine…

Surface Chirality of Gly-Pro Dipeptide Adsorbed on a Cu(110) Surface

Hervé Cruguel, Christophe Méthivier, Claire-Marie Pradier, Vincent Humblot

The adsorption of chiral Gly-Pro dipeptide on Cu(110) has been characterized by combining in situ polarization modulation infrared reflection absorption spectroscopy (PM-RAIRS) and X-ray photoelectron spectroscopy (XPS). The chemical state of the dipeptide, and its anchoring points and adsorption…

High selectivity of TaSiBEA zeolite catalysts in 1,3-butadiene production from ethanol and acetaldehyde mixture

Pavlo I. Kyriienko, Olga V. Larina, Sergiy O. Soloviev, Svitlana M. Orlyk, Stanislaw Dzwigaj

New tantalum-silica based zeolite catalysts (TaSiBEA) were applied in this work for 1,3-butadiene production from ethanol. Tantalum incorporation into vacant T-atom sites of the SiBEA zeolites framework as mononuclear Ta(V) allowed preparing highly selective catalysts for ethanol/acetaldehyde…

Tunable hierarchical porous silica materials using hydrothermal sedimentation-aggregation technique

Abdelali Zaki, Jing Xu, Grégory Stoclet, Sandra Casale, Jean-Philippe Dacquin, Pascal Granger

Herein, a simple and efficient synthesis based on a dual templating approach allow the preparation of tunable macroporous mesoporous silica materials. Macropores incorporation has been obtained using polymer spheres of well-defined size and their subsequent removal by thermal treatment allowed the…

Caracterización in-operando de catalizadores Fe-N-C para la reducción del H2O2 mediante microscopía electroquímica de barrido

Carlos M Sánchez-Sánchez, Christian Candia-Onfray, Ricardo Venegas, Lin Zhang, Sophie Juillard, Ricardo Salazar, José F. Marco, Nieves Menendez, Francisco Javier Recio, Vincent Vivier

Se han desarrollado diferentes rutas sintéticas para obtener catalizadores pirolizados Fe-N-C muy activos para la reacción de reducción de oxígeno (ORR). En particular, presentamos aquí las bases nitrogenadas del ADN y el ARN como precursores de C-N [1]. El H2O2 formado como subproducto durante la…

The Impact of Reduction Temperature and Nanoparticles Size on the Catalytic Activity of Cobalt-Containing BEA Zeolite in Fischer–Tropsch Synthesis

Karolina A Chalupka, Jacek Grams, Pawel Mierczynski, Malgorzata I Szynkowska, Jacek Rynkowski, Thomas Onfroy, Sandra Casale, Stanislaw Dzwigaj

A goal of this work was to investigate the influence of the preparation procedure and activation conditions (reduction temperature and reducing medium: pure hydrogen (100% H 2) or hydrogen-argon mixture (5% H 2-95% Ar)) on the activity of Co-containing BEA zeolites in Fischer-Tropsch synthesis.…
