Enzyme-assisted mineralization of calcium phosphate: exploring confinement for the design of highly crystalline nano-objects

E. Colaço, D. Lefèvre, E. Maisonhaute, D. Brouri, C. Guibert, C. Dupont-Gillain, Karim El Kirat, S. Demoustier-Champagne, J. Landoulsi

In hard tissues of vertebrates, calcium phosphate (CaP) biomineralization is a fascinating process that combines specific physicochemical and biochemical reactions, resulting in the formation of extracellular matrices with elegant nanoarchitectures. Although several “biomimetic” strategies have…

Chemically and Physically Pretreated Straw in Moderate Conditions: Poor Correlation between Biogas Production and Commonly Used Biomass Characterization

Shruthi Meenakshisundaram, Vincenzo Calcagno, Claire Ceballos, Antoine Fayeulle, Estelle Léonard, Virginie Herledan, Jean-Marc Krafft, Yannick Millot, Xiaojun Liu, Claude Jolivalt, André Pauss

Straw is a substantial agricultural by-product for biogas production. Hydrolysis of straw is found to be a rate-limiting step during its anaerobic digestion and could be enhanced by pretreatment. In this paper, the effect of various combinations of particle size reduction, autoclaving, and low-…

A common precursor to both prebiotic and biological pathways to RNA nucleotides

Andrea Pérez-Villa, Thomas Georgelin, Jean-François Lambert, Marie-Christine Maurel, François Guyot, A. Marco Saitta, 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.…

Size-induced structural modifications affecting Co3O4 nanoparticles patterned in SBA-15 silicas

Anne Davidson, Irene Lopez, Nissrine El Hassan, Hadjira Guerba, Gilles Wallez

The structure of Co3O4 nanoparticles patterned in SBA-15 silicas is studied. With pore size of 7.3 nm, bundles of oriented particles, with (400) plane parallel to the hexagonal axis, is revealed by HR-TEM. With decreasing pore sizes, structural modifications, suggested by HR-TEM are confirmed by…

Effect of pore geometry of mesoporous supports on catalytic performances in methane reforming

Joy Tannous, Leila Karam, Marie-Nour Kaydouh, Henri El Zakhem, Nissrine El Hassan, Sandra Casale

Catalysts prepared using three dimensional SBA-16 silica support (composed of micropores and cage-like mesopores) were tested in the reaction of methane dry reforming, in comparison with 2D hexagonal mesoporous SBA-15 support. The samples were evaluated by N 2 sorption and X-Ray diffraction (XRD)…

Influence des paramètres des procédés de fabrication additive métallique sur le comportement en corrosion de l’acier inoxydable 316L, Influence of metal additive manufacturing parameters on the corrosion behavior of 316L stainless steel

Alexis Fouchereau

Ces dernières années, la fabrication additive est devenue une source importante de créativité pour le développement de matériaux complexes qui défient l'utilisation de leurs homologues traditionnels. En fusion laser sur lit de poudre (L-PBF), les propriétés des matériaux sont largement…, In recent years, additive manufacturing has become a significant source of creativity for the development of complex materials which challenge the use of their traditional counterparts. In laser powder bed fusion (L-PBF), the material properties are widely influenced by the process parameters and…

Reshaping Dynamics of Gold Nanoparticles under H2 and O2 at Atmospheric Pressure

Adrian Chmielewski, Jun Meng, Beien Zhu, Yi Gao, Hazar Guesmi, Hélène Prunier, Damien Alloyeau, Guillaume Wang, Catherine Louis, Laurent Delannoy, Pavel Afanasiev, Christian Ricolleau, Jaysen Nelayah

Despite intensive research efforts, the nature of the active sites for O2 and H2 adsorption/dissociation by supported gold nanoparticles (NPs) is still an unresolved issue in heterogeneous catalysis. This stems from the absence of a clear picture of the structural evolution of Au NPs at near…

Characterization and catalytic activity of Mn (salen) immobilized on silica by various strategies

Khalil Tesnime Abou, Chaaben Semy Ben, Boujday Souhir, Bergaoui Latifa

Different strategies were applied to prepare supported Mn(salen) on fumed silica and to explore the effect of the interaction nature between the active sites and the surface on the catalytic activity. Direct and multistep grafting methods were used: the silica surface was silylated and the metal…

Al-Mn-silicate nanobubbles phase as an intermediate in zeolite formation

Amal Bejar, Semy Ben Chaabene, Maguy Jaber, Jean-François Lambert, Latifa Bergaoui

Manganese (II) carbonate, silicic acid and aluminum nitrate were treated hydrothermally at different temperatures (120–210°C) and for different durations (6–72 h) in an aqueous basic medium. Different compositions of starting mixtures were used. The synthetized materials were characterized by…
