Nano-sized iron oxides supported on polyester textile to remove fluoroquinolones in hospital wastewater

In this study, we examined the removal kinetics of two fluoroquinolones (FQs), flumequine (FLU) and ciprofloxacin (CIP), in synthetic wastewater (SWW) and real hospital wastewater (RHW) using FeOx thin films, peroxymonosulfate (PMS) and visible light. Nano ...

Investigation of Biogenic Passivating Layers on Corroded Iron

Julien Maillard

This study evaluates mechanisms of biogenic mineral formation induced by bacterial iron reduction for the stabilization of corroded iron. As an example, the Desulfitobacterium hafniense strain TCE1 was employed to treat corroded coupons presenting urban na ...

Ex-situ experimental benchmarking of solid oxide fuel cell metal interconnects

Jan Van Herle, Manuel Bianco

Solid oxide fuel cells (SOFCs) can convert hydrocarbon fuels, such as methane, into heat and electricity with a high conversion efficiency. The fuel flexibility of the SOFC derives from the high operating temperature (600-900 °C). Such a high temperature s ...

Numerical simulation of the probability of corrosion initiation of RC elements made of reinforcing steel with improved corrosion performance

Eugen Brühwiler, David Conciatori

Steel reinforcing bars in concrete are protected from corrosion by a thin oxide film that is created on the steel surface in the highly alkaline environment of the concrete. Corrosion process begins once this oxide film is destroyed, for example, by chlori ...

Tribocorrosion of passive metals in the mixed lubrication regime: theoretical model and application to metal-on-metal artificial hip joints

Stefano Mischler, Shoufan Cao

Wear is a key problem limiting the lifetime and performance of total hip arthroplasty. The synovial fluid, acting as lubricant, can alleviate the wear of implants but also introduces corrosion. The interaction of mechanical wear and electrochemical corrosi ...

Adhesion of thermoplastic polyurethane elastomer to galvanized steel

Véronique Michaud, Basile Golaz

When a thermoplastic polyurethane elastomer (TPU) is co-molded with galvanized steel, the subsequent adhesion and its durability are very sensitive to the chemical bonds created at the interface. Silane coupling primers are known for enhancing adhesion bet ...

Texture Formation in Hot-Dip Galvanized Coatings : Nucleation and Growth of Anisotropic Grains in a Confined Geometry

Aurèle Mariaux

Continuous hot-dip galvanization is a process during which steel sheets are coated with a layer of Zn-Al alloy to protect them against corrosion. As the name indicates, this is achieved by dipping the preheated sheet into a bath of molten alloy. The sheet ...

Modeling Nucleation and Growth of Zinc Grains in Hot-Dip Galvanized Coatings

Michel Rappaz, Aurèle Mariaux

Hot-dip galvanized Zn-0.2wt%Al coatings on steel sheets exhibit a strong basal texture ({0001} parallel to the sheet plane). Part of this texture call be explained by the faster growth of < 10 (1) over bar0 > dendrites as compared with < 0001 >, granting b ...

Triboelectrochemical techniques and interpretation methods in tribocorrosion: A comparative evaluation

Stefano Mischler

Tribocorrosion is a material deterioration or transformation resulting from simultaneous action of wear and corrosion. Tribocorrosion is found in many engineering applications but the involved mechanisms are still little understood. The investigation of tr ...

The bactericidal effect of TiO2 photocatalysis involves adsorption onto catalysts and loss of membrane integrity, FEMS

César Pulgarin

The bactericidal effect of photocatalysis with TiO2 is well recognized, although its mode of action is still poorly characterized. It may involve oxidation, as illuminated TiO2 generates reactive oxygen species. Here we analyze the bactericidal effect of i ...

Mécanismes d'action du TiO2 illuminé sur Escherichia Coli

Gaëtan Gogniat

The increase of bacterial resistance against various disinfection processes is a worrying phenomenon. As a consequence, the search for alternative techniques for fighting micro-organisms has become one of the major issues of these last few years. In this d ...
