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…

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…

Controlling Magnesium Silicates Coprecipitation Conditions: A Tool to Tune Their Surface Acid–Base Reactivity

François Payan, Albert Issa, Jean-Marc Krafft, Yannick Millot, Thomas Onfroy, Capucine Sassoye, Jean-François Hochepied, Guillaume Laugel, Hélène Lauron-Pernot

Magnesium silicates combining acidic and basic surface properties are known to be interesting as heterogeneous catalysts. Nevertheless, their catalytic performances are highly dependent on the synthesis method used. In this study, a series of magnesium silicates was synthesized for the first time…

Influence of organic additives on the properties of impregnationsolutions and on nickel oxide particle size for Ni/Al2O3catalysts

Faiza Bentaleb, Michel Che, Anne-Claire Dubreuil, Cécile Thomazeau, Eric Marceau

tThe introduction of organic additives, such as polyols, sugars or polyacids, in impregnation solutionshas been suggested to better control the size of nanoparticles on supported catalysts. The present paperfocuses on the roles played by three of these additives, sorbitol, glucose and citric acid,…
