Theoretical and experimental study of the adsorption of neutral glycine on silica from the gas phase

Claire Lomenech, Gregoire Bery, Dominique Costa, Lorenzo Stievano, Jean-François Lambert

The adsorption of neutral glycine onto amorphous silica was investigated both theoretically and experimentally. DFT calculations were performed at the BLYP-631++G** level using a cluster approach. Several possible configurations involving the formation of H-bonds between glycine and one, two or…

Comprehension of cellulose depolymerisation mechanisms induced by iron ions, Compréhension des mécanismes de dépolymérisation de la cellulose induits par les ions fer

Alice Gimat

Degradation of paper by iron gall inks (IGI) is a challenging issue for written heritage conservation. These inks consist of a mixture of iron(II) sulphate, tannins and gum Arabic, and are therefore acidic and iron-rich. Hence, paper degradation by IGI is often attributed to a combination of acid…, La dégradation du papier par les encres ferrogalliques (EFG) est un défi pour la conservation du patrimoine écrit. Ces encres, composées d'un mélange de sulfate de fer (II), de tannins et de gomme Arabique, sont acides et riches en fer. Par conséquent, les mécanismes de dégradation des…

Elaboration of antibiofilm surfaces functionalized with antifungal-cyclodextrin inclusion complexes.

Aïcha Gharbi, Vincent Humblot, Turpin Frédéric, Claire-Marie Pradier, Christine Imbert, Jean-Marc Berjeaud

To tackle the loss of activity of surfaces functionalized by coating and covalently bound molecules to materials, an intermediate system implying the noncovalent immobilization of active molecules in the inner cavity of grafted cyclodextrins (CDs) was investigated. The antifungal and antibiofilm…

Relantionship between the feedstock powders reactivity and the Electrochemical properties of 316L Stainless steel obtained by laser powder bed fusion

Alexis Fouchereau, Beatriz Puga, Hicham Maskrot, Fernando Lomello, Oumaïma Gharbi, Mireille Turmine, Vincent Vivier

3D printing by Laser-Powder Bed Fusion (L-PBF) is an innovative process using a high energy density laser to melt the raw material into a powder form. Previous studies have shown that the powder properties are crucial for the density, quality and microstructure of the materials produced [1, 2] but…

Experimental clues for detecting biosignatures on Mars

J.-C. Viennet, S. Bernard, Corentin Le Guillou, P. Jacquemot, E. Balan, L. Delbes, B. Rigaud, T. Georgelin, M. Jaber

Forthcoming exploration of Mars aims at identifying fossil biosignatures within ancient clay-rich formations. The subsurface of Mars has mostly acted as a giant freezer for the last 4 Gyr, thereby preserving potential remains of martian life. Yet, volcanism and impactors have periodically triggered…

On the kinetics of CO oxidation by O2 over RhI(CO)2 catalytic species anchored to a zeolitic support

Céline Fontaine-Gautrelet, Cyril Thomas, Jean-Marc Krafft, Gérald Djéga-Mariadassou

The reactivity of RhI(CO)2 towards CO oxidation was studied on a model Rh(0.7 wt%)/HY material. The kinetic results show that RhI(CO)2 exhibit a fairly low activity. It is therefore suggested that the catalytic species responsible for the enhanced activity of Rh/Ce0.68Zr0.32O2 [Manuel et al., J.…
