Création de surfaces antibiofilms par greffage covalent de peptides et enzymes antibactériens sur les surfaces de cuivre et de titane, Creation of antibiofilm surfaces : covalent grafting of antimicrobial peptides and enzymes onto copper and titanium surfaces

Jessie Peyre

La contamination bactérienne et le développement de biofilms marins sont des problèmes récurrents, et terriblement coûteux sur les structures immergées des bâtiments de l'armée. L'emploi de composés bactéricides et nocifs pour l'écosystème est désormais interdit. Les travaux menés…, Bacterial contamination and formation of biofilms on immersed structures in seawater are frequent and at the origin of high cost maintenance treatments. The use of compounds biocidal, but also harmful for the ecosystem, is nowadays forbidden. The aim of this thesis work was to find new preventive…

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…

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-…

N2 as a Quantitative FTIR Probe Molecule for Reliable Assessment of the Dispersion of Ru Supported on Hydroxyapatite

Sabrina Akrour, Alexandre Vimont, Guylène Costentin, Cyril Thomas

Accurate assessment of the metal dispersion is known to be important in the field of catalysis, as these data are used to calculate the turnover frequency of a given reaction on a given metal. This study shows that N2 can be used as a Fourier transform infrared spectroscopy (FTIR) probe molecule…

On the influence of water traces on the acidity measurement of amorphous aluminosilicates

Juliette Blanchard, Jean-Marc Krafft, Colin Dupont, Céline Sayag, Toshikazu Takahashi, Hiroyuki Yasuda

For the measurement of their acidity, amorphous aluminosilicates are beforehand treated at temperature of 450 • C or higher in order to remove water adsorbed on their surface. We will show in this study that, during the standard course of an acidity measurement by low temperature CO adsorption,…

A straightforward approach to high purity sodium silicide Na4Si4

Yang Song, Isabel Gómez-Recio, Ram Kumar, Cristina Coelho Diogo, Sandra Casale, Isabelle Génois, David Portehault

Sodium silicide Na4Si4 is a reductive and reactive source of silicon highly relevant to designing non-oxidic silicon materials, including clathrates, various silicon allotropes, and metal silicides. Despite the impor-tance of this compound, its production in high amounts and high purity is still a…
