Nanoscale antiadhesion properties of sophorolipid-coated surfaces against pathogenic bacteria

Claire Valotteau, Niki Baccile, Vincent Humblot, Sophie Roelants, Wim Soetaert, Christian V Stevens, Yves Dufrêne

A current challenge in nanomedicine is to develop innovative strategies to fight infections caused by multiresistant bacterial pathogens. A striking example is antiadhesion therapy, which represents an attractive alternative to antibiotics to prevent and treat biofilm-associated infections on…

Catalytic hydrogen-assisted dehydrochlorination of 1,2-dichloroethane over cobalt-containing beta zeolite

Anna Śrębowata, Rafal Baran, Izabela I. Kamińska, Thomas Onfroy, Jean-Marc Krafft, Stanislaw Dzwigaj

HAlBEA zeolite obtained by calcination of parent TEABEA zeolite at 823 K for 3 h in air following ion exchange with NH4NO3 solution and calcination at 773 K for 3 h was used for synthesis of cobalt containing zeolite by conventional wet impregnation with an aqueous solution of Co(NO3)2. The…

Photocatalyseurs nanocomposites UCNP@SiO2@ZnO, activés par rayonnement proche infrarouge, pour la dépollution des eaux usées, Nanocomposites photocatalysts UCNP@SiO2@ZnO, active under near-infrared light, for wastewater treatment

David Hu

Les photocatalyseurs tels que l’oxyde de zinc (ZnO) peuvent minéraliser les polluants organiques toxiques et persistants dans les eaux usées. Ils ne sont cependant pas efficients dans les eaux très contaminées, suite à la nécessité d’une activation par une lumière UV qui n’y pénètre que faiblement…, Photocatalysts such as zinc oxide (ZnO) can mineralize toxic and persistent organic pollutants present in wastewaters. Unfortunately, these photocatalysts loose part of their effectiveness because they need to be activated by UV light, which has a limited penetration depth in highly contaminated…

Hydrolysis of Ammonia-Borane over Ni/ZIF-8 Nanocatalyst: High Efficiency, Mechanism, and Controlled Hydrogen Release

Changlong Wang, Jimena Tuninetti, Zhao Wang, Chen Zhang, Roberto Ciganda, Lionel Salmon, Sergio Moya, Jaime Ruiz, Didier Astruc

Non-noble metal nanoparticles are notoriously difficult to prepare and stabilize with appropriate,dispersion, which in ttirn severely limits their catalytic functions. Here, using zeolitic imidazolate framework (ZIF-8) as MOF template, catalytically remarkably- efficient, ligand-free first-row late…

Surface orientation dependent interaction of cobalt (II) precursors with alpha-alumina

Céline Chizallet, Christian Schlaup, Emiliano Fonda, Xavier Carrier

The performances of alumina-supported cobalt catalysts strongly depend on Co/alumina interactions, that are poorly understood. In the present work, α-alumina surfaces are used as models of polycrystalline support, to unravel their orientation dependent behavior by GI-EXAFS. The CoII/α-alumina…

Ni-Silica-based Catalysts for CH4 Reforming by CO2 with Enhanced Stability: Recent Designs and the Impacts of Ni Confinement, Promoters, and Core-Shell Structures

Oscar Daoura, Maya Boutros, Franck Launay

CO2 reforming of CH4, also referred to as the Dry Reforming of Methane (DRM), is considered an excellent method to produce H2 and CO (syngas), which are known to be used for the production of higher alkanes and oxygenates. Despite nickel’s moderate toxicity, Ni-based heterogeneous catalysts are…
