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 gas phase species produced in rf plasmas of hexamethyldisiloxane (HMDSO), Si2O(CH3)(6), diluted with oxygen, have been investigated. The complementarity of Fourier transform infrared absorption spectroscopy and mass spectrometry allows the determinatio ...
The redn. of NO by CO or C3H6 in the presence of O2, a reaction of great technol. importance, was studied on porous polycryst. Rh catalyst films using a single-chamber and a wireless bipolar cell configuration. In the latter case the Rh catalyst films were ...
The solubility of carbon monoxide in 37 ionic liquids and in some organic solvents has been determined using high-pressure C-13 NMR spectroscopy; a method for predicting the CO solubility is demonstrated, and it was shown that the rate of the hydroformylat ...
A model for the electrochem. promotion induced by electrochem. generated promoting species is proposed. The formation rate of promoters is assumed to be proportional to the availability of free surface sites at the solid electrolyte/catalyst/gas three-phas ...
Novel efficient structured combustion catalysts based on sintered metal fiber filters (MFF) were developed. To increase sp. surface area (SSA), metal fibers were coated by crack-free porous oxide films of SiO2, Al2O3, porous glass, and mesoporous SBA-15 si ...
Seven structurally distinct pentadienyl type lithium and potassium compds. were screened against a variety of electrophiles in order to assess the regioselectivity of the trapping reactions. Organoborates and analogs thereof (fluorodimethoxyborane) proved ...
This work reports the hydrogenation of carbon dioxide/inorganic carbonate salts to formic acid/formate in two phase systems comprising an ionic phase, in which the catalyst is immobilized, and an aqueous phase in which the carbonates and formate are confin ...
2,3-Dichloropyridines undergo a mono- or a dicarbonylation in the presence of carbon monoxide, an alc., and a palladium catalyst, affording selectively either alkyl 3-chloropyridine-2-carboxylates or dialkyl pyridine-2,3-dicarboxylates in good yields, depe ...
Transient kinetics in the toluene oxidn. over V/Ti oxide catalysts prepd. by grafting and impregnation have been compared. V4+ cations are supposed to be the sites for the formation of electrophilic oxygen species participating in deep oxidn. Another oxyge ...
The homogeneous hydrogenation of carbon dioxide into formate anion has been investigated in aqueous solution, using water soluble ruthenium(II)-phosphine (meta-monosulphonated triphenylphosphine, TPPMS; and 1,3,5-triaza-7-phosphaadamantane, PTA) complexes ...
