Ethylene production via catalytic dehydration of diluted bioethanol: a step towards an integrated biorefinery

Ilenia Rossetti, Matteo Compagnoni, Elisabetta Finocchio, Gianguido Ramis, Alessandro Di Michele, Yannick Millot, Stanislaw Dzwigaj

After a preliminary thermodynamic investigation, proper operating conditions have been selected to maximize ethylene productivity by ethanol dehydration and limit side products such as coke and higher olefins or oxygenates. We focused on the possibility to operate with a diluted bioethanol solution…

Heterogeneous Partial (amm) Oxidation and Oxidative Dehydrogenation Catalysis on Mixed Metal Oxides

Jacques C. Védrine

This paper presents an overview of heterogeneous partial (amm)oxidation and oxidative dehydrogenation (ODH) of hydrocarbons. The review has been voluntarily restricted to metal oxide-type catalysts, as the partial oxidation field is very broad and the number of catalysts is quite high. The main…

Phosphoribosyl Pyrophosphate: A Molecular Vestige of the Origin of Life on Minerals

Mariame Akouche, Maguy Jaber, Marie-Christine Maurel, Jean-François Lambert, Thomas Georgelin

In this contribution, we report the formation under prebiotic conditions of phosphoribosyl pyrophosphate (PRPP) as a molecular precursor in the one-pot synthesis of a canonical nucleotide, namely adenosine monophosphate (AMP) from its building blocks (KH2PO4 or Pi, adenine, and d-ribose), on a…

Fate of Organic Molecules in the Mars Regolith Under UV Radiation Deduced from the MOMIE Laboratory Experiment

Cyril Szopa, Patrice Coll, Fabien Stalport, Olivier Poch, Maguy Jaber, Jean-François Lambert, Laura Rouquette, Jérôme Lasne

Among bioindicators or biosigna- tures, organic molecules present on Mars could be re- trieved in the regolith near the surface due to erosion of rocks and gardening of the soil from meteorites bom- bardment through the Mars history. Once their, the organic molecules are submitted to the harsh…

Pseudoaneurysm of anterior tibial artery following a diaphyseal fracture ă of the tibia mimicking a malignant bone tumor

Pierre Sautet, Elie Choufani, Philippe Petit, Franck Launay, Jean-Luc Jouve, Sebastien Pesenti

Pseudoaneurysms of the lower limb are rare and frequently iatrogenics ă complications. Closed traumas are likely to generate lesions of the ă arterial wall, which generally become symptomatic at a later stage. The ă diagnosis of such vascular lesion is difficult because the ă symptomatology and the…

Coupling morphological evolution and multiphase transport to Decipher degradation in PEM water electrolyzers

Youssef Kharchouf, Loïc Assaud, Mireille Turmine, Vincent Vivier

In this work, we present a multiphase numerical model for the corrosion degradation of proton exchange membrane water electrolyzers. The numerical framework comprises two main components, a geometry tracking component and a performance evaluation component. The geometry tracking is based on the…

From 8-hydroxy-5-sulfoquinoline to new related fluorogenic ligands for complexation of aluminium(III) and gallium(III)

Franck Launay, Valérie Alain-Rizzo, Émilie Destandau, Nathalie Ramos, Ēlisabeth Bardez, Paul Baret, Jean-Louis Pierre

The hexadentate tripodal ligand O-TRENSOX (already known as a siderophore), incorporating three 8-hydroxy-5- sulfoquinoline (8-HQS) subunits, was investigated as a potential Ñuorogenic ligand of Al(III) and Ga(III). For the sake of comparison, every chelation study was also carried out with n-BUSOX…

Development of a thermodynamic approach to assist the control of the precipitation of hydroxyapatites and associated calcium phosphates in open systems

Corentin Reynaud, Cyril Thomas, Sandra Casale, Sophie Nowak, Guylène Costentin

The understanding of the precipitation mechanisms of calcium phosphates (CaPs) remains extremely challenging despite its fundamental interest for material sciences and its practical implications in medicine, paleosciences, and chemistry, especially for heterogeneous catalysis. The competitive…

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…
