Silica-Supported Au-Ag Catalysts for the Selective Hydrogenation of Butadiene

Nazila Masoud, Laurent Delannoy, Christophe Calers, Jean-Jacques Gallet, Fabrice Bournel, Krijn P. de Jong, Catherine Louis, Petra E. de Jongh

Gold and silver are miscible over the entire composition range, and form an attractive combination for fundamental studies on bimetallic catalysts. Au–Ag catalysts have shown synergistic effects for different oxidation and liquid-phase hydrogenation reactions, but have rarely been studied for gas-…

Au-Modified Pd catalyst exhibits improved activity and stability for NO direct decomposition

Taha Elgayyar, Josefine Schnee, Alain Tuel, Laurence Burel, Francoise Bosselet, Yves Schuurman, Frederic C Meunier, Laurent Delannoy, Cyril Thomas

The direct decomposition of NO x at moderate temperatures is a challenge because of the poisoning of the surface of noble metals by oxygen, yet the modification of Pd with Au enables obtaining a highly stable catalyst under an O 2-free feed at 450°C. Care was taken to ensure that the reaction was…

Electrospun Poly(ε-caprolactone) Fiber Scaffolds Functionalized by the Covalent Grafting of a Bioactive Polymer: Surface Characterization and Influence on in Vitro Biological Response

Gana Amokrane, Vincent Humblot, Emile Jubeli, Najet Yagoubi, Salah Ramtani, Véronique Migonney, Céline Falentin-Daudré

The purpose of this study is to present the poly(caprolactone) (PCL) functionalization by the covalent grafting of poly(sodium styrene sulfonate) on electrospun scaffolds using the "grafting from" technique and evaluate the effect of the coating and surface wettability on the biological…

Intermittent dynamics of bubble dissolution due to interfacial growth of fat crystals

Irma Liascukiene, Gabriel Amselem, Jessem Landoulsi, Deniz Gunes, Charles Baroud

Foams are inherently unstable objects, that age and disappear over time. The main cause of foam aging is Ostwald ripening: smaller air bubbles within the foam empty their gas content into larger ones. One strategy to counter Ostwald ripening consists in creating armored bubbles, where solid…

Application of Arrhenius law to DP and zero-span tensile strength measurements taken on iron gall ink impregnated papers: relevance of artificial ageing protocols

Véronique Rouchon, Oulfa Belhadj, Maroussia Duranton, Alice Gimat, Pascale Massiani

Iron gall inks (IGI) were largely used for writing until the nineteenth century. Under certain circumstances, they provoke a substantial degradation of their cellulosic support.It was shown in a previous works thatc ombination of oxygen and iron largely impacts cellulose chain breaking occurring in…

Effect of the niobium state on the properties of NbSiBEA as bifunctional catalysts for gas- and liquid-phase tandem processes

Pavlo I. Kyriienko, Olga V. Larina, Nataliia O. Popovych, Sergiy O. Soloviev, Yannick Millot, Stanislaw Dzwigaj

NbSiBEA zeolites contained isolated framework mononuclear Nb(V) (Nb0.7SiBEA) and a mixture of framework mononuclear and extra-framework polynuclear Nb(V) (Nb2.0SiBEA) were prepared by two-step postsynthesis method as evidenced by XRD, NMR, DR UV–vis and FTIR. DR UV–vis showed that two types of…
