Surface IR immunosensors for label-free detection of benzo[a]pyrene

Souhir Boujday, Soumaya Nasri, Michele Salmain, Claire-Marie Pradier

Polycyclic aromatic hydrocarbons (PAHs) are a family of contaminants originating from the incomplete combustion of organic compounds, present in the urban air, water, soil and also foodstuff. Due to their recognised carcinogenicity, their concentration in urban air is routinely monitored and…

Mesostructured or Alumina-mesostructured Silica SBA-16 as Potential Support for NOx Reduction and Ethanol Oxidation

Maya Boutros, Thomas Onfroy, Patrick da Costa

Synthesis of some meso-structured SiO2 or aluminosilica (SBA-16 and Al-SBA-16) with a 3-dimensional cubic structure is reported. Structural and porosity properties of these materials were studied by x-ray diffraction, N2 sorption, and transmission electron microscopy imaging.; Al insertion was detd…

Mechanism and deactivation process of the conversion of methylbutynol on basic faujasite monitored by operando DRIFTS

Jean-Francois Groust, Guylene Costentin, Jean-Marc Krafft, Pascale Massiani

The successive steps occurring during conversion of methylbutynol (MBOH) on a basic NaX zeolite catalyst were characterized by combined micro-GC and operando DRIFT spectroscopy, assocd. to TPD-MS expts. These techniques permit to reveal a very strong and fast initial decrease in MBOH consumption,…

Genesis of supported carbon-coated Co nanoparticles with controlled magnetic properties, prepared by decomposition of chelate complexes

Konstantin Tarasov, Patricia Beaunier, Michel Che, Eric Marceau, Yanling Li

Following procedures formerly developed for the prepn. of supported heterogeneous catalysts, carbon-coated cobalt nanoparticles dispersed on porous alumina have been prepd. by impregnation of γ-Al2O3 with (NH4)2[Co(EDTA)] and thermal decompn. in inert atm. Below 350 °C, Co(II) ions are complexed…

Dimerization of Uracil in a simulated Mars-like UV radiation environment

Laura Rouquette, Fabien Stalport, Hervé Cottin, Cyril Colas, Thomas Georgelin, Naïla Chaouche-Mechidal, Jerome Lasne, Sara Mahfouf, Franćois Raulin, Laura Selliez, Cyril Szopa, Patrice Coll

The search for organic molecules at the surface of Mars is a key objective in astrobiology, given that many organic compounds are possible biosignatures and their presence is of interest with regard to the habitability of Mars. Current environmental conditions at the martian surface are harsh and…

Impact of sorbitol addition on the structure and performance of silica-supported cobalt catalysts for Fischer-Tropsch synthesis

Hong Jingping, Eric Marceau, Andrei Y. Khodakov, Anne Griboval-Constant, Camille La Fontaine, Françoise Villain, Valérie Briois, P.A. Chernavskii

The paper focuses on the impact of sorbitol addition on the genesis of cobalt active phases in silica-supported catalysts and on their performance in Fischer-Tropsch synthesis. The catalysts were characterized by ex situ and in situ diffuse reflectance spectroscopy in the ultraviolet and visible…

Non-Hydroxyl Radical Species Production during Dark Air Oxidation of Alluvial Soils

Elora Bourbon, Frédéric Averseng, Pierre Le Pape, Thierry Allard, Fulvia Baratelli, Fabrice Alliot, Alexandre Gélabert, Valentine Rollot, Elodie Guigon, Jessica Brest, Sylvie Nélieu, Guillaume Morin

Natural environments subjected to hydrologically-driven redox fluctuations are regarded as propitious to contaminant degradation since they favor cyclic oxygenation of Fe(II)-minerals that produces oxidizing reactive species, such as the hydroxyl radical, OH • . However, the identity of these…
