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.
This dissertation is concerned with the development of a methodology and appropriate tools for the investigation of chemical reaction systems using measured data. More specifically, the determination of reaction stoichiometry and kinetics from concentratio ...
In order to investigate the origin of the effect of non faradaic electrochem. modification of catalytic activity (NEMCA), a Kelvin probe was used to measure in situ the changes induced in the work function of an IrO2 catalyst film deposited on yttria-stabi ...
The kinetics and the mechanism of the selective redn. of nitric oxides (NOx) by hydrogen is studied on a trimetallic Pt-Mo-Co/a-Al2O3 catalyst under oxidizing conditions. This system is interesting in view of an exhaust gas control of power plants or lean- ...
Redn. of NO and N2O by CO over a SiO2-supported iron oxide catalyst was studied by the transient response method, with different initial oxidn. states of the catalyst, i.e., completely reduced (Fe3O4), or oxidized (Fe2O3). The affect of CO pre-adsorption w ...
The reduction of N2O to N2 on iron oxide under transient conditions was studied in the temperature range of 270–340°C. Six different models were used to simulate the experimental data. The conventional second-order reaction between gas phase N2O and surfac ...
The highly efficient Semliki Forest virus (SFV) system has been applied to express several recombinant 7TM receptors and ligand-gated ion channels. High affinity binding and functional coupling to G proteins were obtained for the receptors. The ligand-gate ...
We studied using x-ray photoelectron spectroscopy the deposition of Au, In, Ag and Al overlayers onto clean-cleaved GaTe(001) surfaces at room temperature. The first steps of the Schottky barrier formation on Au and In showed no interface reactions. Free T ...
The heterogeneous reactions of NO3 on NaCl and KBr salt were studied at room temp. using a Knudsen reactor equipped with dual detection, namely Laser induced fluorescence and mass spectrometry. The uptake coeffs. of NO3 were g=(4.9+-3).10-2 onto NaCl and g ...
Bromine contg. compds. are thought to play an important role in the O3 destruction in various regions of the atm. Recent studies of atm. Br chem. suggest that HOBr is one of the important Br compds. The rapid photolysis of HOBr in daytime releases Br atoms ...
Monoclonal IgA was produced under serum free conditions by a murine hybridoma cell line (ZAC3) in a hollow fiber, a continuous stirred tank and a fluidized bed reactor. Differences in the antibody adsorption to DEAE chromatog. matrixes, an essential step i ...
