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.
A consortium was created to investigate electroceramic materials that show ionic or mixed ionic-electronic conduction (MIEC), for application as oxygen separation membranes and in solid oxide fuel cells (SOFC, electrolytes and cathodes). The focus is on de ...
The reactions of (E,E)-1-benzyloxy-2-methylpenta-1,3-diene (9) with 3,3-dimethyl-2-(trimethylsilyloxy)butene and (Z)-3-(trimethylsilyloxy)pent-2-ene in SO2 and a Lewis acid give silyl sulfinates that are quenched with Met to generate the corresponding (Z)- ...
Secondary fly ash, resulting from thermal treatment processes, leads to a highly concd. chloride soln. with Cu, Pb, Cd and Zn as main heavy metals when dissolved in water. The selective electrodeposition of these heavy metals was studied. The goal was to r ...
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 ...
The chem. redn. of anthraquinone(I) has at least 2 disadvantages on the industrial scale; therefore, an electrochem. method was developed. The electrochem. redn. of I is done in a 2-compartment cell using concd. H2SO4 (15-17 mol/dm3) as the electrolyte at ...
The electrochem. prepn. of ceric sulfate [13590-82-4] was studied in concd. H2SO4 (10 mol/dm3). The current efficiency of the reaction increases considerably if a mixed catalyst (Ag2SO4 + MnSO4) is used. [on SciFinder (R)] ...
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 ...
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 ...
Recent progress in our development of anode supported electrolyte (ASE) SOFcells is reported. The cells are fabricated by cocasting of aqueous slurries of NiO/YSZ and 8YSZ, followed by cofiring. A gradient cathode is deposited by screenprinting successive ...
