Modélisation de la tribocorrosion d'aciers inoxydables dans l'eau à haute pression et haute température

Several metallic components of pressurized water reactors (PWR) used in nuclear power plants are exposed to the combined degradation by friction and corrosion (tribocorrosion). In PWR, corrosion arises from the water pressurized at 150 bars and maintained ...

Ultraviolet Photodetectors Based on Anodic TiO2 Nanotube Arrays

Nicola Marzari, Ke Huang

Anodic TiO2 nanotube arrays prepared by electrochemical anodization were used to fabricate ultraviolet (UV) photodetectors. The devices annealed at 450 degrees C exhibit the highest UV-sensitive photoconductance due to the pure anatase phase of the TiO2. T ...

Comparative evaluation of polymer surface functionalization techniques before iron oxide deposition. Activity of the iron oxide-coated polymer films in the photo-assisted degradation of organic pollutants and inactivation of bacteria

César Pulgarin, Félicien Mazille

The preparation of iron oxide-coated polymer films and their photocatalytic activity in organic pollutants degradation and bacterial inactivation is described. Polyvinyl fluoride (PVF), polyethylene (PE) and polyethylene terephtalate (PET) films were used ...

Cathode thickness-dependent tolerance to Cr-poisoning in solid oxide fuel cells

Christos Comninellis, Jan Van Herle, Josef Andreas Schuler, Pietro Tanasini

This work aimed to set new guidelines for the quantification of Cr accumulation in solid oxide fuel cell cathodes after operation, and enabled to pinpoint a diffusion-controlled tolerance to Cr-poisoning for increased cathode thickness; the additional cath ...

RedOx study of anode supported solid oxide fuel cell

Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes, Arata Nakajo, David Dubois

The common technology for solid oxide fuel cells (SOFC) is based on a cermet (ceramic-metal composite) anode of nickel with yttria stabilized zirconia (YSZ), often used as the supporting structure. One of the main limitations of this technology is the tole ...
