Silane Layers on Silicon Surfaces: Mechanism of Interaction, Stability, and Influence on Protein Adsorption

Nesrine Aissaoui, Latifa Bergaoui, Jessem Landoulsi, Jean-François Lambert, Souhir Boujday

In this work the mechanism of (3-aminopropyl)triethoxysilane (APTES) interaction with silicon surfaces is investigated at the molecular level. We studied the influence of experimental parameters such as time, temperature, and concentration on the quality of the APTES layer in terms of chemical…

Catalytic activity and thermostability of enzymes immobilized on silanized surface: Influence of the crosslinking agent

Nesrine Aissaoui, Jessem Landoulsi, Latifa Bergaoui, Souhir Boujday, Jean-François Lambert

In this work, we investigate the influence of crosslinkers on the operational and heat stability of immobilized enzymes on a silanized silicon surface. To this end, glucose-6-phosphate dehydrogenase (G6PDH), a model multimeric enzyme, was attached through bifunctional crosslinkers able to bind…

Evolution Mechanisms of T91 Steel in Subcritical Conditions and Role of an Internal Oxidation Zone

Seifallah Fetni, David Montero, Chokri Boubahri, Dalil Brouri, Jalel Briki

Corrosion of a T91 steel tube, used in subcritical conditions in an oil power plant for 157,000 h, was characterized mainly through SEM, TEM, EDX and DRX analyses. Severe oxidation and carburization took place in both the outer (boiler) and inner (steam) wall sides. The nature and morphology of the…

A Hydrothermal-Sedimentary Context for the Origin of Life

Frances Westall, Keyron Hickman-Lewis, Nancy Hinman, Pascale Gautret, Kathleen A Campbell, Jean-Gabriel Bréhéret, Frédéric Foucher, Axelle Hubert, Stephanie Sorieul, Avinash Vicholous Dass, Terence P. Kee, Thomas Georgelin, André Brack

Critical to the origin of life are the ingredients of life, of course, but also the physical and chemical conditions in which prebiotic chemical reactions can take place. These factors place constraints on the types of Hadean environment in which life could have emerged. Many locations, ranging…

Chiral Ammonium-Capped Rhodium(0) Nanocatalysts: Synthesis, Characterization, and Advances in Asymmetric Hydrogenation in Neat Water

Elodie Guyonnet Bil É, Elodie Cortelazzo-Polisini, Audrey Denicourt-Nowicki, Rita Sassine, Franck Launay, Alain Roucoux

Optically active amphiphilic compounds derived from N-methylephedrine, N-methylprolinol, or cinchona derivatives possessing bromide or chiral lactate counterions were efficiently used as protective agents for rhodium(0) nanoparticles. The full characterization of these surfactants and the obtained…

Reactivity of oxygen species formed upon N2O dissociation over Fe-ZSM-5 zeolite: CO oxidation as a model

Hazar Guesmi, Dorothée Berthomieu, Lioubov Kiwi-Minsker

The oxidative power toward CO of α-oxygen formed upon N2O dissociation over isolated and binuclear Fe/ZSM-5 zeolite is investigated by means of DFT calculations. The two α-sites [Fe-O]+ and [Fe-(μO)-(μOH)-Fe]+ exchanged in ZSM-5 were considered since their activity in the N2O decomposition was…
