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…

High-Current-Density CO2-to-CO Electroreduction on Ag-Alloyed Zn Dendrites at Elevated Pressure

Sarah Lamaison, David Wakerley, Juliette Blanchard, David Montero, Gwenaelle Rousse, Dimitri Mercier, Philippe Marcus, Dario Taverna, Domitille Giaume, Victor Mougel, Marc Fontecave

High-surface-area Ag-Zn-alloyed electrodes undertake the rapid conversion of CO 2 to CO. This has the combined benefit of removing CO 2 and producing an industrially relevant chemical synthon. At atmospheric pressure, the electrodes plateau in activity owing to the mass-transport limitation of CO 2…

Ni/CeO2 Nanoparticles Promoted by Yttrium Doping as Catalysts for CO2 Methanation

Valeria La Parola, Chao Sun, Patricia Beaunier, Leonarda F Liotta, Patrick da Costa

Ni (5 wt.%) catalysts over yttrium modified CeO2 oxides synthesized by hydrothermal method were prepared. For comparison Ni was supported over pure CeO2 and Y2O3. Characterizations by N2 adsorption/desorption, XRD, XPS, TEM/HRTEM, H2-TPR, CO2-TPD and TGA were carried out. The catalytic performance…

Optimization of Synthesis Conditions of Ni/SBA-15 Catalysts: Confined Nanoparticles and Improved Stability in Dry Reforming of Methane

Nissrine El Hassan, Marie-Nour Kaydouh, Nissrine El, Anne Davidson, Pascale Massiani

Despite its economic and environmental advantages, the dry reforming of methane using supported Ni-based catalysts remains challenging due to problems of metal particle sintering and carbon deposition, which lead to loss in catalytic activity. In this study, different silica supports, containing 5…

Characterization of omega-functionalized undecanethiol mixed self-assembled monolayers on Au(111): A combined polarization modulation infrared reflection-absorption spectroscopy/X-ray photoelectron spectroscopy/periodic density functional theory study

Frederik Tielens, Dominique Costa, Vincent Humblot, Claire-Marie Pradier

The structure of undecanethiol self-assembled monolayers (SAMs) on Au(111) with -COOH and -OH tail groups has been characterized by combining experimental and theoretical techniques. The pure and mixed 1:1 SAMs were investigated. It was found using polarization modulation infrared reflection-…

Spiky gold shells on magnetic particles for DNA biosensors

Erin Bedford, Souhir Boujday, Claire-Marie Pradier, Frank Gu

Combined separation and detection of biomolecules has the potential to speed up and improve the sensitivity of disease detection, environmental testing, and biomolecular analysis. In this work, we synthesized magnetic particles coated with spiky nanostructured gold shells and used them to…

Molecular Understanding of the Bulk Composition of Crystalline Nonstoichiometric Hydroxyapatites: Application to the Rationalization of Structure-Reactivity Relationships

Manel Ben Osman, Jean Marc Krafft, Yannick Millot, Frederic Averseng, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Crystalline hydroxyapatite samples (HAps) have been prepared by using the co-precipitation method under various pH conditions, leading to nonstoichiometric solids (1.65 < Ca/P < 1.77). The aim of this study was to rationalize the sensitivity of the catalytic activity of HAps to their bulk…
