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…

Selective hydrodechlorination of 1,2-dichloroethane on NiSiBEA zeolite catalyst: Influence of the preparation procedure on a high dispersion of Ni centers

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

NixSiBEA zeolites (x = 1-2 Ni wt.%) were prepared by a two-steps postsynthesis method which consists of (1) creation of vacant T-sites by dealumination of tetraethylammonium BEA zeolite with nitric acid and then (2) impregnation of resulting SiBEA zeolite with an aqueous solution of Ni(NO3)2,…

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…

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…

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…

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…

A comparative study of the catalysis of peptide bonds formation by oxide surfaces

Jean-Francois Lambert, Maguy Jaber, Thomas Georgelin, Lorenzo Stievano

It is well-known that amino acids deposited on some inorganic oxides undergo peptidic condensation. It is seldom realised however that a large diversity of behaviours can be observed in such systems. Here we use the apparently simple case of glycine-non-porous silica as a reference system, in which…
