Operando X‐ray Absorption Study of TiO₂‐supported Au, Cu, and Au–Cu Catalysts for Butadiene Selective Hydrogenation

Abdallah Nassereddine, Laurent Delannoy, Xavier Carrier, Catherine Louis, Camille La Fontaine, Anthony Beauvois, Jaysen Nelayah, Axel Wilson

The selective hydrogenation of unsaturated hydrocarbons is essential for the production of alkenes used in polymerization processes. Au‐based catalysts offer greater selectivity than Pd but are limited by poor hydrogen activation. Alloying Au with Cu offers a promising approach to enhance catalytic…

Influence of the Ageing and Drying Steps of a CoMoP/γ‐Al2O3 Catalyst onto the Multi‐Scale Molybdenum Active Phase Organization

Candice Cottrez, Séverine Humbert, Anne‐sophie Gay, Elodie Devers, Frédéric de Geuser, Xavier Carrier, Alexandra Chaumonnot

To study the influence of ageing and drying steps onto the multiscale Mo active phase arrangement (i. e. MoS2 slabs and slab aggregates), a series of highly loaded CoMoP/γ-Al2O3 catalysts aged, unaged, dried or freeze-dried were prepared and tested in toluene hydrogenation. Electron Probe Micro…

Structure and Surface Study of Hydroxyapatite-Based Materials: Experimental and Computational Approaches

Guylène Costentin, Christophe Drouet, Fabrice Salles, Stéphanie Sarda

In addition to designing catalytic materials ever more active and selective, the emergence of new classes of greener catalysts remains very challenging. The apatite family system with hydroxyapatite (HA) structure appears as a good candidate for catalysis due to its eco-compatibility properties,…

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…

Unraveling the Mechanisms of Hypertrophy-Induced Matrix Mineralization and Modifications in Articular Chondrocytes

Ilhem Lilia Jaabar, Brittany Foley, Alberto Mezzetti, Françoise Pillier, Francis Berenbaum, Jessem Landoulsi, Xavier Houard

Chondrocyte hypertrophic differentiation is a main event leading to articular cartilage degradation in osteoarthritis. It is associated with matrix remodeling and mineralization, the dynamics of which is not well characterized during chondrocyte hypertrophic differentiation in articular cartilage.…

Combined fungal and chemical pretreatment of lignocellulosic biomass for biogas production: Effect of pretreatment order and fungal strains

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

The recalcitrance of lignocellulosic poses a challenge for conversion to biogas and therefore, pretreatment is an essential step in addressing this. Combining fungal pretreatment with a biomimetic system, a mild Fenton reaction, was studied to improve the methane production from straw. The…
