Catalytic conversion of trichloroethylene on nickel containing beta zeolites into value added products

A. Śrębowata, R. Baran, D. Lisovytskiy, I.I. Kamińska, S. Dzwigaj

Nickel containing BEA zeolites, NiSiBEA and NiHAlBEA, with 2 wt% of Ni were prepared by a two-step postsynthesis method and conventional wet impregnation. The calcination of NiSiBEA and NiHAlBEA at 773 K for 3 h in air led to the formation of C-NiSiBEA and C-NiHAlBEA. After reduction at 873 K for 3…

Co–Ru Nanoalloy Catalysts for the Acceptorless Dehydrogenation of Alcohols

Brandon Azeredo, Tayssir Ben Ghzaiel, Ning Huang, Kamila Kaźmierczak, Wenjie Shen, Guillaume Wang, Delphine Schaming, Patricia Beaunier, Philippe Decorse, Noémie Perret, Jennifer Peron, Marion Giraud, Carine Michel, Lorette Sicard, Jean-Yves Piquemal

The synthesis of Co–Ru bimetallic nanoparticles was performed by co-reduction of Co(II) and Ru(III) salts in octan-1-ol, acting both as a solvent and a mild reducing agent. The metal composition was varied in the entire range, from pure Co to pure Ru. Although Co and Ru are miscible in the bulk,…

Stabilisation of small mono- and bimetallic gold–silver nanoparticles using calix[8]arene derivatives

Priyanka Ray, Marie Clément, Cyril Martini, Ibrahim Abdellah, Patricia Beaunier, José-Luis Rodriguez-Lopez, Vincent Huc, Hynd Remita, Isabelle Lampre

In this paper, we report the synthesis of octa(hydroxy)-octa(mercaptobutoxy)calix[8]arene and its use as a stabiliser of nanoparticles (NPs). We show that the reduction of gold and/or silver ions in the presence of this calix[8]arene in ethanolic solutions leads to the formation of very small…

Room-Temperature Synthesis of Iron-Doped Anatase TiO2 for Lithium-Ion Batteries and Photocatalysis

Christian Andriamiadamanana, C. Laberty-Robert, Moulay Tahar Sougrati, Sandra Casale, Carine Davoisne, Snehangshu Patra, Frédéric Sauvage

Iron-doped nanocrystalline particles of anatase TiO2 have been successfully synthesized using a complete room-temperature synthetic approach, leading to particles of high surface area (280 m2/g) and a narrowed band gap of 2.3 eV. These particles were introduced for photocatalysis under white light…

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…

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…

Silk bionanocomposites : design, characterization and potential applications, Bionanocomposites à base de soie : élaboration, caractérisation et applications potentielles

Cristina Belda Marín

Silk-based bionancompoistes have attracted a growing interest in numerous applications, particularly in the biomedical field, owing to their ability to combine the specific properties of silk fibroin (biodegradability, biocompatibility and interesting mechanical properties) and nanoparticles (NPs…, Les « bionanocomposites » à base de soie sont des matériaux qui suscitent un intérêt croissant dans de nombreuses applications, et en particulier dans le domaine biomédical, de par leur capacité à combiner les propriétés de la fibroïne (biodégradabilité, biocompatibilité et propriétés mécaniques…

Ionization thermodynamics of poly(acrylic acid) in ionic liquids

Ryo Kanzaki, Clément Guibert, Jérôme Fresnais, Véronique Peyre

The pH response of poly(acrylic acid) (pAA) in protic ionic liquids (PILs), ethylammonium nitrate and diethylethanolammonium trifluoromethanesulfonate, was investigated through potentiometric and calorimetric titrations. The ionization equilibrium of pAA in the PILs, as well as in aqueous solution…
