Biomass-mediated ZSM-5 zeolite synthesis: when self-assembly allows to cross the Si / Al lower limit

Marcelo Maciel Pereira, Elisa Gomes, Alessandra Vieira Silva, Ana Belen Pinar, Marc-Georg Willinger, Sangaraju Shanmugam, Céline Chizallet, Guillaume Laugel, Pit Losch, Benoit Louis

A family of Al-rich ZSM-5 zeolites with Si / Al = 8 ± 0.5 was prepared according to a biomass-mediated supramolecular approach. A combination of advanced characterisation techniques and periodic density functional theory (DFT) calculations unraveled the purity and stability of unexpected Al-…

Insights into bacteriophage T5 structure from analysis of its morphogenesis genes and protein components.

Yvan Zivanovic, Fabrice Confalonieri, Luc Ponchon, Rudi Lurz, Mohamed Chami, Ali Flayhan, Madalena Renouard, Alexis Huet, Paulette Decottignies, Alan R Davidson, Cécile Breyton, Pascale Boulanger

Bacteriophage T5 represents a large family of lytic Siphoviridae infecting Gram-negative bacteria. The low-resolution structure of T5 showed the T=13 geometry of the capsid and the unusual trimeric organization of the tail tube, and the assembly pathway of the capsid was established. Although major…

Surface-induced assembly of sophorolipids

Jessie Peyre, Ahmed Hamraoui, Marco Faustini, Vincent Humblot, Niki Baccile

The surface self-assembly properties of acidic sophorolipids, a bolaform microbial glycolipids with pH-responsive properties in solution, were studied based on the chemical nature of the support and pH of the solution. Sophorolipids generally form micelles in water but formation of morphologies…

Discrimination of infrared fingerprints of bulk and surface POH and OH of hydroxyapatites

Sarah Diallo-Garcia, Manel Ben Osman, Jean-Marc Krafft, Souhir Boujday, Guylene Costentin

The identification of the nature of the surface acid base pairs present on hydroxyapatites surface is a key point to rationalize their catalytic properties. To investigate the possible involvement of acidic protonated phosphate (POH) and/or of basic OH emerging from the channels, the spectroscopic…

Controlled Formation of Native Defects in Ultrapure ZnO for the Assignment of Green Emissions to Oxygen Vacancies

Fredeŕic Averseng, Miao Zhang, Frederic Averseng, Jean-Marc Krafft, Patrizia Borghetti, Guylène Costentin, Slavica Stankic

Ultrapure ZnO nanopowders were synthesized via vapor-phase based methods under oxygen deficient conditions. The type and relative proportions of intrinsic point defects were studied by photoluminescence (PL) and EPR spectroscopies performed under strictly controlled conditions. Besides coupled PL/…

Vibrating single probe and stationary bi-probes to measure local electrochemical impedance spectroscopy.

Hisasi Takenouti, G. Galicia, Michel Keddam, Vincent Vivier

The electrochemical impedance spectroscopy is widely used to investigate the electrode kinetics. This method is recognized as a powerful method to discriminate one reaction model to another and also to evaluate the reaction rate of elementary steps. However, when the electrode kinetics is markedly…

Superior Stability of Au/SiO 2 Compared to Au/TiO 2 Catalysts for the Selective Hydrogenation of Butadiene

Nazila Masoud, Laurent Delannoy, Herrick Schaink, Ad van Der Eerden, Jan Willem de Rijk, Tiago A. G. Silva, Dipanjan Banerjee, Johannes D. Meeldijk, Krijn P. de Jong, Catherine Louis, Petra E. de Jongh

Supported gold nanoparticles are highly selective catalysts for a range of both liquid-phase and gas-phase hydrogenation reactions. However, little is known about their stability during gas-phase catalysis and the influence of the support thereon. We report on the activity, selectivity, and…

Aerobic oxidation of alcohols using ruthenium supported on DD3 kaolin

B. Zadam, D. Obaid, A. Mayoufi, P. Beaunier, F. Launay, F. El Berrichi

Supported ruthenium nanoparticles were prepared through the chemical reduction of aqueous Ru(III) species previously loaded (1 or 5 wt%) onto DD3 kaolin through an ion-exchanged pathway. Resulting nanoporous materials were characterized by XRF, XRD, TEM, EDX, and N2 sorption measurements, and then…
