Deciphering the role and nature of phosphate species at the surface of stainless steel immersed in phosphoric acid solutions

I. Liascukiene, M. Ben Salah, Ph. Refait, L. Dhouibi, C. Methivier, J. Landoulsi, M. Jeannin

We investigate the evolution of the surface of a highly alloyed stainless steel (Sanicro 28) upon immersion in aqueous phosphoric acid solutions. For this purpose, both short-(few hours) and long-term immersion (several days) were carried out. A detailed analysis of XPS spectra allowed a…

La Recherche en Chimie aux Frontières de la Connaissance

Dominique Massiot, Claire-Marie Pradier, Jacques Maddaluno, Jean-François Tassin, Joël Moreau, Mehran Mostafavi, Anne Imberty, Pascal Breuilles, Catherine Larroche

L’Unité Mixte de Recherche est la brique élémentaire, souple et pérenne d’un paysage de la recherche en évolution rapide. De nombreux dispositifs viennent structurer l’activité de ces équipes pour faire émerger des pôles de recherche, consolider le maillage des réseaux nationaux, identifier les…, Mixed research units are building blocks, flexible but permanent, in rapidly evolving fields of research. Several measures shape the activities of research teams and thus give rise to “poles of research”. They also help consolidate national networks, identify strong points, boost the sharing of top…

A TEM and UV-visible study of silver reduction by ethanol in Ag-alumina catalysts

Elie Sayah, Dalil Brouri, Yiaho Wu, Andrea Musa, Patrick da Costa, Pascale Massiani

A transmission electron microscopy (TEM) study dedicated to the understanding of dispersion and location of Ag nanospecies in silver-alumina catalysts is reported. A special attention is put on the conditions of powder catalyst deposition on the grids for TEM analysis. When the deposition is…

Antibacterial surfaces developed from bio-inspired approaches

K. Glinel, P. Thébault, Vincent Humblot, Claire-Marie Pradier, T. Jouenne

Prevention of bacterial adhesion and biofilm formation on the surfaces of materials is a topic of major medical and societal importance. Various synthetic approaches based on immobilization or release of bactericidal substances such as metal derivatives, polyammonium salts and antibiotics were…

Role of the Al source in the synthesis of aluminum magadiite

Yunfei Bi, Juliette Blanchard, Jean-François Lambert, Yannick Millot, Sandra Casale, Shuangqin Zeng, Hong Nie, Dadong Li

The role of the aluminum source on the insertion of Al in the silicate layers during the hydrothermal crystallization of magadiite (NaSi7O13(OH),4H2O), a lamellar silicate, was investigated. Three aluminum sources were compared: aluminum isopropoxide, aluminum sulfate and aluminum hydroxide We…

Extension of a kinetic model for NO oxidation and NOx storage to fixed-bed Pt/Ba/Al2O3 catalysts

Nikola Rankovic, Andre Nicolle, David Berthout, Patrick da Costa

Following our work on modeling of monolith catalysts, we herein focus on developing a fixed-bed reactor model in the AMESim modeling platform. A kinetic model for NO oxidn. and NOx storage over Pt/Ba/Al2O3 recently developed in the literature was successfully implemented and validated against the…

Light olefin transformation over ZSM-5 zeolites with different acid strengths - A kinetic model

P. Oliveira, P. Borges, R. Ramos Pinto, M. A. N. D. A. Lemos, F. Lemos, Jacques C. Vedrine, F. Ramoa Ribeiro

The authors analyzed the influence of the acidity of a ZSM-5 catalyst on the catalytic transformation of various short-chain olefins (ethylene, propylene and 1-butene). Four ZMS-5 catalysts with different acid strength distributions were studied at different temps. and partial pressures. The…

NMR cogwheel phase cycling determination with web tools: Amplitude-modulated z-filter MQMAS sequence

Yannick Millot, Redouane Hajjar, Pascal P. Man

Our recent method based on the use of web tools (XML and XSLT) for constructing cogwheel phase cycles is extended to the selection of two sym. coherence transfer pathways in the case of an amplitude-modulated z-filter MQMAS sequence. For all spins (I=3/2, 5/2, 7/2 and 9/2) and all MQ expts. we…
