Ionic liquids as environmentally friendly corrosion inhibitors : the inhibition of mechanism of butylammonium nitrate for Al AA2024-T6

Oumaïma Gharbi, Abdelmoheiman Zakaria Benbouzid, Mai T.T. Tran, Mireille Turmine, Vincent Vivier

Ionic liquids are a promising class of solvent exhibiting a large panel of attractive physico-chemical properties, which can be of interest for energy, electrocatalysis or corrosion protection applications. Therefore, in the context of European restriction REACH regulation towards chromate-based…

Co-grafting of amino-poly(ethylene glycol) and Magainin I on a TiO2 surface: tests of antifouling and antibacterial activities.

Jessie Peyre, V. Humblot, C. Méthivier, J.M. Berjeaud, C.-M. Pradier

An antimicrobial peptide, Magainin I (Mag), was grafted to a titanium oxide surface, via an antiadhesive poly(ethylene glycol) (PEG) cross-linker. The latter plays a 2-fold part, being antiadhesive, and enabling the covalent immobilization of the peptide. The functionalization was characterized at…

Lipase-embedded Silica Nanoparticles with Oil-filled Core-Shell Structure: Stable and Recyclable Platforms for Biocatalysts

Yasutaka Kuwahara, Takato Yamanishi, Takashi Kamegawa, Kohsuke Mori, Michel Che, Hiromi Yamashita

Lipase enzyme was embedded within silica nanoparticles with oil-filled core-shell structure. The enzyme embedded within such architecture retained all of its activity and showed high catalytic performance both in water and in organic media with optimal stability and recyclability.

ZSM-5/SBA-15 microporous/mesoporous composites prepared by a microwave-assisted zeolitisation of Al-SBA-15 mesoporous solids

Sami Habib, Franck Launay, Henri El Zakhem, Matjaž Mazaj, Flavien Guenneau, Patricia Beaunier, Dalil Brouri, Nataša Novak Tušar, Venčeslav Kaučič, Antoine Gedeon

ZSM-5/SBA-15 composites with high textural properties were synthesised by a microwave-assisted zeolitisation of Al-SBA-15 in the presence of tetrapropylammonium bromide. The effect of the hydrothermal treatment temperature and of ammonium fluoride, often used as a catalyst, was studied. Resulting…

Visualization of localized deformation and fluid flow in sedimentary rocks

Jeroen van Stappen, Maartje Houben, Timotheus K.T. Wolterbeek, Alessandro Tengattini, Takahiro Shinohara, Floris S.R. Teuling, Miao Zhang, Christopher Spiers, Suzanne J.T. Hangx

<p>Subsurface activities, such as energy production or geo-storage, affect the natural equilibrium of the reservoir and surrounding geological system. Fluid production from porous sandstones, for example, is often associated with reservoir compaction and induced seismicity, such as…

In situ detection and characterization of potable water biofilms on materials by microscopic, spectroscopic and electrochemistry methods

Jean Gamby, Alain Pailleret, Carol Boucher Clodic, Claire-Marie Pradier, Bernard Tribollet

We studied biofilm formation on stainless steel occurring in a drinking water distribution system which operated in parallel at 20 and 37 °C, in order to focus on the effect of temperature rather than on other operational and water quality parameters. A surface conditioning step was followed as a…

Insights into the influence of the Ag loading on Al2O3 in the H2-assisted C3H6-SCR of NOx

Tesnim Chaieb, Laurent Delannoy, Guylène Costentin, Catherine Louis, Sandra Casale, Ruth L. Chantry, Z.Y. Li, Cyril Thomas

The addition of H2 has been reported to promote drastically the selective catalytic reduction of NOx by hydrocarbons (HC-SCR). Yet, the influence of the Ag loading on the H2-promoted HC-SCR has been the subject of a very limited number of investigations. The H2-HC-SCR earlier studies reported…

Effect of postsynthesis preparation procedure on the state of copper in CuBEA zeolites and its catalytic properties in SCR of NO with NH3

Rafal Baran, Frederic Averseng, Dominik Wierzbicki, Karolina Chalupka, Jean-Marc Krafft, Teresa Grzybek, Stanislaw Dzwigaj

Copper-containing BEA zeolites, Cu2.0SiBEA and Cu2.0HAlBEA, with 2 wt % of Cu were prepared by a two-step postsynthesis method and a conventional wet impregnation, respectively. These zeolites were characterized by XRD, DR UV–vis, EPR, FTIR and TPR physicochemical techniques. The incorporation of…

Covalent immobilization of glucose oxidase on mesocellular silica foams: Characterization and stability towards temperature and organic solvents

Noemie Balistreri, Dorian Gaboriau, Claude Jolivalt, Franck Launay

Glucose oxidase (GOx) immobilization onto mesoporous SBA-15 silica and two mesocellular foams (MCF) characterized by similar surface area and pore volumes but different pore/cell dimensions was examined. The covalent grafting of the enzyme through amide bonds was evidenced by controlling pH…

Hydrodenitrogenation of indole over Mo2C catalyst: Insights into mechanistic events through DFT modeling

Witold Piskorz, Grzegorz Adamski, Andrzej Kotarba, Zbigniew Sojka, Céline Sayag, G. Djéga-Mariadassou

The molecular reaction mechanism of hydrodenitrogenation of indole was studied using density-functional theory calculations of the adsorbed o-ethylaniline surrounded by mobile hydrogen atoms. It was found that the hydrogenation of o-ethylaniline occurs through two steps: consisting in…
