Design of TiO2/Au nanoparticle films with controlled crack formation and different architectures using a centrifugal strategy

Abdelhafed Taleb, Frederic Mesguich, Thomas Onfroy, Xue Yanpeng

Here we present an approach to design hybrid nanocomposite films based on TiO2/Au nanoparticles using centrifugation processes. The prepared nanocomposite films have been characterized by different techniques such as FEGSEM, TEM, BET and XRD. Furthermore it is demonstrated that centrifugal force…

Corrosion propagation monitoring using electrochemical noise measurements on carbon steel in hydrogenocarbonated solution containing chloride ions

Chloé Comas, François Huet, Kieu Ngo, Marion Fregonese, Hassane Idrissi, Bernard Normand

The propagation of localized corrosion on API 5 L X65 carbon steel in hydrogenocarbonated solution containing chloride ions was monitored during long immersion times by electrochemical noise (EN) measurements in ZRA mode. Monitoring corrosion propagation from the EN amplitude is possible but…

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…

Co-grafting of antiadhesive and antimicrobial agents onto UV-micropatterned copper surfaces

Jessie Peyre, Vincent Humblot, Christophe Méthivier, Jean-Marc Berjeaud, Claire-Marie Pradier

Adhesion of proteins and bacteria was reduced by a factor close to one order of magnitude, and adhered bacteria were dramatically damaged on copper surfaces by grafting a PEG-modified PMMA-based (polymethyl methacrylate) copolymer together with an antimicrobial peptide. To obtain PEG and a peptide…

The controlled synthesis of metal-acid bifunctional catalysts: Selective Pt deposition and nanoparticle synthesis on amorphous aluminosilicates

Jadid E. Samad, Juliette Blanchard, Celine Sayag, Catherine Louis, John R. Regalbuto

The rational synthesis of metal-acid bifunctional catalysts based on aluminosilicates will involve control over which domain – alumina or silica – the metal can be deposited on, as well as the control of particle size. These factors determine the ratio and proximity of the metal and acid sites. The…

Experimental clues for detecting biosignatures on Mars

J.-C. Viennet, S. Bernard, Corentin Le Guillou, P. Jacquemot, E. Balan, L. Delbes, B. Rigaud, T. Georgelin, M. Jaber

Forthcoming exploration of Mars aims at identifying fossil biosignatures within ancient clay-rich formations. The subsurface of Mars has mostly acted as a giant freezer for the last 4 Gyr, thereby preserving potential remains of martian life. Yet, volcanism and impactors have periodically triggered…

Scanning Electrochemical Microscopy for Investigating Gas Bubble/Liquid Interfaces

Claude Gabrielli, François Huet, Michel Keddam, Philippe Rousseau, Vincent Vivier

Scanning electrochemical microscopy was used to characterize air bubble/electrolyte interfaces for bubbles of diameter in the millimeter range. Contrary to rigid insulated substrate/liquid interfaces, the approach of the tip of the microelectrode was shown to lead to a deformation of the bubble…

Synthesis of small Ni-core–Au-shell catalytic nanoparticles on TiO2 by galvanic replacement reaction

Julien Reboul, Z. y Li, Jun Yuan, Kazuki Nakatsuka, Masakazu Saito, Kohsuke Mori, Hiromi Yamashita, Yu Xia, Catherine Louis

We report the first preparation of small gold–nickel (AuNi) bimetallic nanoparticles (<5 nm) supported on titania by the method of galvanic replacement reaction (GRR), evidenced by the replacement of Ni atoms by Au atoms according to the stoichiometry of the reaction. We showed that this…

Application of Arrhenius law to DP and zero-span tensile strength measurements taken on iron gall ink impregnated papers: relevance of artificial ageing protocols

Véronique Rouchon, Oulfa Belhadj, Maroussia Duranton, Alice Gimat, Pascale Massiani

Iron gall inks (IGI) were largely used for writing until the nineteenth century. Under certain circumstances, they provoke a substantial degradation of their cellulosic support.It was shown in a previous works thatc ombination of oxygen and iron largely impacts cellulose chain breaking occurring in…
