Heterogeneous Fenton-like reactions in natural soils and sediments at neutral pH with O2 as oxidant

Elora Bourbon, Frederic Averseng, Thierry Allard, Pierre Le Pape, Sylvie Nélieu, Xavier Carrier, Guillaume Morin, Elodie Guigon, Fulvia Baratelli, Sophie Ayrault

Heterogeneous Fenton-like processes using O2 as oxidant and iron(II) minerals as substrate is a rapidly growing research field with important implications especially for in-situ organic pollutant degradation in natural media. These reactions can be conducted at neutral pH and several minerals are…

Insight into the mechanism of action of temporin-SHa, a new broad-spectrum antiparasitic and antibacterial agent

Zahid Raja, Sonia André, Feten Abbassi, Vincent Humblot, Olivier Lequin, Tahar Bouceba, Isabelle Correia, Sandra Casale, Thierry Foulon, Denis Sereno, Bruno Oury, Ali Ladram

Antimicrobial peptides (AMPs) are promising drugs to kill resistant pathogens. In contrast to bacteria, protozoan parasites, such as Leishmania, were little studied. Therefore, the antiparasitic mechanism of AMPs is still unclear. In this study, we sought to get further insight into this mechanism…

Surface segregation in AuPd alloys: Ab initio analysis of the driving forces

Jérôme Creuze, Hazar Guesmi, Christine Mottet, Beien Zhu, Bernard Legrand

In order to determine the energetic driving forces for surface segregation in AuPd alloys, we use a combined approach coupling ab initio calculations and an analysis via an effective Ising model. Previously, this approach has been used successfully in the framework of N-body interatomic potentials…

Time-of-Flight Secondary Ion Mass Spectrometry Investigation of the Orientation of Adsorbed Antibodies on SAMs Correlated to Biorecognition Tests

Victor Lebec, Souhir Boujday, Claude Poleunis, Claire-Marie Pradier, Arnaud Delcorte

The adsorption of an antiglutamate dehydrogenase (Anti-GDH) antibody on different surfaces was studied to probe its orientation and bioactivity. Three different situations were investigated: physisorption on a −COOH-terminated thiols self-assembled monolayer (SAM) on gold, covalent grafting on the…

Développement de biocathodes pour biopiles enzymatiques utilisant la laccase, Development of an enzymatic cathode biofuel cell using laccase

Mohamed Achraf Blout

Les biopiles enzymatiques constituent une alternative intéressante de production d'électricité renouvelable. On s'est intéressé dans ce travail au compartiment cathodique d'une biopile utilisant la laccase, une oxydase multi-cuivres, comme biocatalyseur pour la réduction de l'…, Enzymatic biofuel cells are an attractive alternative for renewable electricity generation. In this work, we are focusing on the cathodic compartment of a biofuel cell using laccase, a multi-copper oxidase, as biocatalysts for the oxygen reduction reaction (ORR) by direct electron transfer of…

ZnFe2O4 pour des applications en photocatalyse hétérogène dans le visible, ZnFe2O4 for heterogeneous photocatalysis applications in the visible

Aya Jezzini

Ce travail de thèse concerne la dépollution des eaux en utilisant des mélanges très enrichis en ferrite de zinc et activés par de la lumière visible. Nos solides ont été testés pour deux réactions : 1) l’oxydation et décomposition d’un antibiotique, l’amoxyciline ou AMX très utilisée en médecine…, Our work is devoted to the water depollution by photocatalysis with mixtures enriched in Zn ferrites and under visible light. It concerns 1) Amoxicilin (AMX), as one of the pharmaceutical polluting molecule that can be found in water and may have a toxic effect. 2) Bacterium Staphylococcus…

Design de composites verts pour la dépollution des terres agricoles : expérience et théorie, Design of green composite for the decontamination of agricultural land : experimental and theoretical

Khaled El Adraa

Des matériaux verts biodégradables à base de Montmorillonite et de cystéine ont été préparés dans le but de co-adsorber des cations de métaux lourds et des polluants émergeants en combinant l’expérience et la théorie (calculs DFT). Les analyses thermiques différentielles ont permis d’estimer le…, Layered silicates like smectites are important soil components. Many works have been devoted to functionalize these materials in order to increase their chelating properties which may help retain heavy metals. It is well known that Cd2+, Hg2+, Pb2+, Co2+ and Zn2+ forms stable complexes with sulfur-…

Selectivity in the gas-phase hydrogenation of 4-nitrobenzaldehyde over supported Au catalysts

Noémie Perret, Xiaodong Wang, Thomas Onfroy, Christophe Calers, Mark A Keane

The effects of Au particle size and support properties have been examined in the gas-phase hydrogenation of 4-nitrobenzaldehyde over Au/ZrO2, Au/TiO2 and Au/Al2O3. Gold particle size was varied using deposition-precipitation and impregnation syntheses. The catalysts have been characterised in terms…
