Design and Analytical Performances of a Diclofenac Biosensor for Water Resources Monitoring

Yacine Mazouzi, Antoine Miche, Alexis Loiseau, Bruno Beito, Christophe Méthivier, Dietmar Knopp, Michèle Salmain, Souhir Boujday

Because the broadly consumed pain killer diclofenac (DCF) is a recognized pollutant, monitoring of its concentration is routinely performed in surface waters. As a valuable alternative to chromatographic and immunochemical assays, we developed a piezoelectric immunosensor to quantify DCF, first in…

Effect of pH on the incorporation of acrylic acid units in the core of polymer nanoparticles prepared by PISA and on their morphology

Clément Debrie, Noémie Coudert, Jean-Michel Guigner, Fanny Coumes, Clément Guibert, Simon Harrisson, François Stoffelbach, Olivier Colombani, Jutta Rieger

Polymerization-induced self-assembly (PISA) is a polymerization process in which amphiphilic block copolymers are simultaneously synthesized and self-assembled in a selective solvent, leading to nanoparticles of different morphologies. Copolymerization has been reported as a means to tune…

Design of Bifunctional Catalysts Based on Bea Zeolites for Tandem Processes with Participation of Ethanol

N. O. Popovych, O. V. Larina, S. M. Orlyk, P. I. Kyriienko, S. O. Soloviev, S. Dzwigaj

The results from the creation of BEA zeolite catalysts, containing heteroelements of Ta(Nb) and modified with d-metals (Ag, Cu, Zn), for processes involving ethanol, are presented. The activity of Ag/BEA in the selective reduction of nitrogen oxides (NOx) with ethanol is due to the presence of…

Characterisation and Reactivity of Oxygen Species at the Surface of Metal Oxides

M. Anpo, Guylène Costentin, E. Giamello, H. Lauron-Pernot, Z. Sojka

Surface reactive oxygen species play a fundamental role in selective oxidation and combustion reactions catalyzed by metal oxides. Unravelling the nature of these transient species, and understanding the details of both their electronic structure and reactivity has been for decades one of the prime…

Atomic Scale Observation of the Structural Dynamics of Supported Gold Nanocatalysts under 1,3‐Butadiene by in situ Environmental Transmission Electron Microscopy

Abdallah Nassereddine, Laurent Delannoy, Christian Ricolleau, Catherine Louis, Alloyeau D., Guillaume Wang, Qing Wang, Hazar Guesmi, Jaysen Nelayah

Supported gold catalysts have been reported to exhibit exceptional selectivity towards the desirable product, an alkene, in chemoselective hydrogenation of highly unsaturated alkynes and alkadienes. However, insights on the interactions between the gold nanoparticles and the 1,3‐butadiene…

Potential Role of Inorganic Confined Environments in Prebiotic Phosphorylation

Avinash Vicholous Dass, Maguy Jaber, André Brack, Frédéric Foucher, Terence P Kee, Thomas Georgelin, Frances Westall

A concise outlook on the potential role of confinement in phosphorylation and phosphate condensation pertaining to prebiotic chemistry is presented. Inorganic confinement is a relatively uncharted domain in studies concerning prebiotic chemistry, and even more so in terms of experimentation.…

Photochemistry of organic molecules in the Solar System: experimental studies outside the International Space Station. The cases of glycine, and nucleobases

Hervé Cottin, Giovanni Strazzulla, M. Dobrijevic, Frances Westall, Gaelle Coussot, A. Le Postollec, Nicolas Fray, Didier Chaput, Richard C. Quinn, . Andrew Mattioda, Giuseppe Baratta, Mario Accolla, Thomas Georgelin, Fabien Stalport, Laura Rouquette, Cyril Szopa, Kafila Saiagh, Jodie Bellila, Katia Grira, Andreas Elsaesser, Nathalie Carrasco, Avinash-Vicholous Dass, M. E. Palumbo

Solar UV radiation is a major source of energy for initiating chemical evolution towards complex organic structures, but it can also photo-dissociate even the most complex molecules. Thus, solar UV can erase the organic traces of past life at the surface of planets, such as Mars, destroy organic…

A Hydrothermal-Sedimentary Context for the Origin of Life

Frances Westall, Keyron Hickman-Lewis, Nancy Hinman, Pascale Gautret, Kathleen A Campbell, Jean-Gabriel Bréhéret, Frédéric Foucher, Axelle Hubert, Stephanie Sorieul, Avinash Vicholous Dass, Terence P. Kee, Thomas Georgelin, André Brack

Critical to the origin of life are the ingredients of life, of course, but also the physical and chemical conditions in which prebiotic chemical reactions can take place. These factors place constraints on the types of Hadean environment in which life could have emerged. Many locations, ranging…
