Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The perovskite-type mixed oxide La0.3Sr0.55Ti0.95Ni0.05O3−δ (LSTN) is demonstrated to exhibit the remarkable property of structural regeneration, where Ni can be reversibly exsoluted from the host perovskite lattice resulting in a regenerable Ni catalyst f ...
The aim of this Note is to predict by means of large eddy simulations the three-dimensional structures and secondary mass and heat fluxes which develop within a heated curved duct, for applications to rocket engines cooling channels. We show the existence ...
Degradation observed on long term stack tests may be explained in part by microstructural changes of the electrodes. Particularly at the anode side, the coarsening of nickel particles will affect its performances. Increasing the metal particle size will fi ...
A solid oxide fuel cell structure obtainable by selective electrochemical processing, comprising an electrolyte membrane (4) formed by a thin film more than 50nm but less than l0[mu]m thick, covering a supporting structure (1) made of a bulk substrate, the ...
A general procedure based on the oxalate coprecipitation route was developed to produce very sinterable ceria (CeO2) powder doped with Gd2O3, Sm2O3 or Y2O3. The method is simple, reliable and very reproducible. Without any milling step, powder of 20 mol% G ...
Ceria-zirconia-ceria sandwich structured composite filmelectrolytes were designed in order to offer high ionic and low electronicconductivity electrolyte films. Calculation of oxygen potential profile inthe composite film electrolyte indicates that a very ...
A simple technique for microstructuring ceramic thin films by micromachining substrates using standard photolithographic techniques was investigated. The ceramic perovskite is used to illustrate the method because of its importance for the fabrication of e ...
Perovskite derived Ni catalysts offer the remarkable benefit of regeneration after catalyst poisoning or Ni particle growth through the reversible segregation of Ni from the perovskite-type oxide host. Although this property allows for repeated catalyst re ...
oarse 8YSZ powders destined for plasma spray deposition were obtained from three different suppliers (Hochrhein, Magnesium Elektron, Unitec). Their ionic conductivities were measured by impedance spectroscopy on pellets prepared by vacuum hot pressing. Den ...
