Molecular mechanism of barnacle adhesion : a structural approach and underlying biochemistry, Mécanisme moléculaire de l'adhésion des balanes : approche structurale et biochimie sous-jacente

Sunyoung Hur

Barnacles adhere themselves robustly and permanently to diverse underwater substrates through strong interactions of a multi-protein complex layer called the “cement”. However, the intermolecular interactions responsible for the strong adhesive properties of the barnacle cement remains poorly…, Les balanes adhèrent de manière robuste et permanente à divers substrats sous-marins grâce à de fortes interactions d’une couche complexe multiprotéique appelée « ciment ». Cependant, les interactions intermoléculaires responsables des fortes propriétés adhésives du ciment de bernacle restent mal…

Novel insights on H2S and COS removal for gas purification applications

David Chiche, Laure Neveux, Vincent Girard, Taha Hlayhel, Karin Barthelet, Javier Pérez-Pellitero, Arnaud Baudot, Delphine Bazer-Bachi, Anne-Sophie Gay, Schweitzer Jean-Marc, Loïc Favergeon, Michèle Pijolat, Christophe Geantet, Guylene Costentin

H₂S and COS are well-known gaseous pollutants encountered in many applications. Synthetic fuels produced from thermochemical routes (Fisher-Tropsch based XTL processes) or IGCC technologies for cleaner power production are among the applications for which the removal of H<…

High selectivity of TaSiBEA zeolite catalysts in 1,3-butadiene production from ethanol and acetaldehyde mixture

Pavlo I. Kyriienko, Olga V. Larina, Sergiy O. Soloviev, Svitlana M. Orlyk, Stanislaw Dzwigaj

New tantalum-silica based zeolite catalysts (TaSiBEA) were applied in this work for 1,3-butadiene production from ethanol. Tantalum incorporation into vacant T-atom sites of the SiBEA zeolites framework as mononuclear Ta(V) allowed preparing highly selective catalysts for ethanol/acetaldehyde…

Structure–Activity Relationship in Manganese Perovskite Oxide Nanocrystals from Molten Salts for Efficient Oxygen Reduction Reaction Electrocatalysis

Francisco Gonell, Carlos M Sánchez-Sánchez, Vincent Vivier, Christophe Méthivier, Christel Laberty-Robert, David Portehault

We report a synthesis pathway in molten salts toward ligand-free nanoparticles of the layered perovskite La0.5Sr1.5MnO4 (l-LSMO) and of the pseudocubic perovskite La0.7Sr0.3MnO3 (pc-LSMO). These particles are readily implemented as oxygen reduction reaction (ORR) electrocatalysts in alkaline…

Synthesis of RNA nucleotides in plausible prebiotic conditions from ab initio computer simulations

Andrea Pérez-Villa, Antonino Marco Saitta, Thomas Georgelin, Jean-François Lambert, François Guyot, Marie-Christine Maurel, Fabio Pietrucci

Understanding the mechanism of spontaneous formation of ribonucleotides under realistic prebiotic conditions is a key open issue of origins-of-life research. In cells, de novo and salvage nucleotide enzymatic synthesis combines 5-phospho-α-d-ribose-1-diphosphate (α-PRPP) and nucleobases.…

A straightforward approach to high purity sodium silicide Na4Si4

Yang Song, Isabel Gómez-Recio, Ram Kumar, Cristina Coelho Diogo, Sandra Casale, Isabelle Génois, David Portehault

Sodium silicide Na4Si4 is a reductive and reactive source of silicon highly relevant to designing non-oxidic silicon materials, including clathrates, various silicon allotropes, and metal silicides. Despite the impor-tance of this compound, its production in high amounts and high purity is still a…

Leucine on Silica: A Combined Experimental and Modeling Study of a System Relevant for Origins of Life, and the Role of Water Coadsorption

Hagop Abadian, Pauline Cornette, Dominique Costa, Alberto Mezzetti, Christel Gervais, Jean-François Lambert

Leucine on silica constitutes an interesting system from the point of view of origins of life studies since leucine coadsorbed on SiO2 together with glutamic acid can give rise to rather long linear polypeptides upon activation. It is also an ideal system to test methods of molecular…

Production and Characterization of Activated Carbon from Orange Peels by Chemical Activation with Sulfuric Acid

Sami Guiza, Salwa Hajyahia, Franck Launay, Mohamed Bagane

Oranges represent 75% of the total citrus fruits (Guiza in Ecol Eng, 99: 134–140, 2017) throughout the world, and Tunisia is one of the major juice producers. Orange peels could cause a significant disposal problem but they are also valuable biomass wastes (Valdes et al. in Langmuir 18: 2111–2116,…

Hierarchical Self-Assembly of Polyoxometalate-Based Organo Palladium(II) Metallomacrocycles via Electrostatic Interactions

Raphaël Salles, Benjamin Abécassis, Etienne Derat, Dalil Brouri, Aurélie Bernard, Qichun Zhang, Anna Proust, Christophe Desmarets, Guillaume Izzet

The design and synthesis of a supramolecular square composed of polyoxometalate-based hybrid donors and ethylenediamine palladium(II) nodes are reported. The structure of the metallomacrocycle scaffold was inferred by diffusion NMR, small-angle X-ray scattering (SAXS), and molecular modeling. The…
