Activation of C‐H Bond of Propane by Strong Basic Sites Generated by Bulk Proton Conduction on V‐Modified Hydroxyapatites for the Formation of Propene

Sarah Petit, Cyril Thomas, Yannick Millot, Jean-Marc Krafft, Christel Laberty-Robert, Guylène Costentin

Insights into the catalytic transformation of propane to propene on V‐apatites catalysts are provided based on structure‐reactivity relationships. Substitution of phosphates by vanadates in the hydroxyapatite structure leads to the formation of Ca10(PO4)6‐x(VO4)x(OH)2‐yOy V‐oxy‐hydroxy‐apatite…

Surface-generated copper ions induce multilayer growth of small peptides

Jessem Landoulsi, Vincent Dupres, Christophe Méthivier, Ivan Leteyi Mfiban, Pauline Cornette, Elodie Colaço, Claire-Marie Pradier

Herein, we investigate the adsorption behavior of a small peptide, Glu-Cys-Gly, in aqueous solution onto copper surface and unravel a mechanism of growth of a hybrid peptide-copper multilayer the thickness of which may exceed a hundred of nanometers. Thanks to a combined set of surface…

Heteroaggregation and Selective Deposition for the Fine Design of Nanoarchitectured Bifunctional Catalysts: Application to Hydroisomerization

Olfa Ben Moussa, Lionel Tinat, Xiaojing Jin, Walid Baaziz, Olivier Durupthy, Celine Sayag, Juliette Blanchard

We successfully prepared bifunctional catalysts with the distance between metallic and acid sites tuned at the nanometer scale. Sols of β-zeolite nanoparticles were synthesized and mixed in optimized conditions with a γ-AlOOH boehmite suspension to yield alumina/zeolite aggregates with a nanometer…

Towards the synthesis of mixed oxides with controlled stoichiometry from Prussian blue analogues

Virgile Trannoy, Amélie Bordage, Jordan Dezalay, Romuald Saint-Martin, Eric Rivière, Patricia Beaunier, Cédric Baumier, Camille La Fontaine, Giulia Fornasieri, Anne Bleuzen

Controlling the synthesis of mixed oxides is of great interest since their stoichiometry influences the properties. We present here the transformation of the Co4[Fe(CN)6]2.7 Prussian blue analogue (PBA) into the mixed Co1.8Fe1.2O4 spinel oxide, with a detailed characterization of the final phase (…

Polyol Process Coupled to Cold Plasma as a New and Efficient Nanohydride Processing Method: Nano-Ni 2 H as a Case Study

Sonia Haj-Khlifa, Sophie Nowak, Patricia Beaunier, Patricia de Rango, Michaël Redolfi, Souad Ammar-Merah

An alternative route for metal hydrogenation has been investigated: cold plasma hydrogen implantation on polyol-made transition metal nanoparticles. This treatment applied to a challenging system, Ni-H, induces a reordering of the metal lattice, and superstructure lines have been observed by both…

Metallomics in deep time and the influence of ocean chemistry on the metabolic landscapes of Earth's earliest ecosystems

Keyron Hickman-Lewis, Barbara Cavalazzi, Stéphanie Sorieul, Pascale Gautret, Frédéric Foucher, Martin Whitehouse, Heejin Jeon, Thomas Georgelin, Charles Cockell, Frances Westall

Modern biological dependency on trace elements is proposed to be a consequence of their enrichment in the habitats of early life together with Earth's evolving physicochemical conditions; the resulting metallic biological complement is termed the metallome. Herein, we detail a protocol for…

Triple structuration and enhanced corrosion performance of 316L in Laser-Powder Bed Fusion

Alexis Fouchereau, Hicham Maskrot, Fernando Lomello, Sophie Bosonnet, Oumaïma Gharbi, Benoit Gwinner, Pierre Laghoutaris, Frédéric Schuster, Vincent Vivier, Beatriz Puga

This work focuses on the influence of the feedstock powders on the microstructural properties and corrosion behavior of 316L stainless steel (SS) produced by laser powder bed fusion (L-PBF) from two different suppliers. Microstructural investigations conducted after additive manufacturing reveal…

Hierarchical collagen-hydroxyapatite nanostructures designed through layer-by-layer assembly of crystal-decorated fibrils

Elodie Colaço, Dalil Brouri, Nesrine Aissaoui, Pauline Cornette, Vincent Dupres, Rute F Domingos, Jean-François Lambert, Emmanuel Maisonhaute, Karim El Kirat, Jessem Landoulsi

A comprehensive understanding of the mechanism by which type I collagen (Col) interacts with hydroxyapatite nanoparticles (Hap NPs) in aqueous solutions is a pivotal step for guiding the design of biologically relevant nanocomposites with controlled hierarchical structure. In this paper we use a…
