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 electrochem. behavior of synthetic B-doped diamond thin-film electrode (BDD) was studied in acid media contg. 4-chlorophenol (4-CP) by cyclic voltammetry, chronoamperometry, and bulk electrolysis. The results showed that in the potential region of supp ...
Results concerning the coupling of the steam reforming and total oxidn. of methanol in a two-passage reactor are presented. A com. available copper-based catalyst is used for the steam reforming. For the total oxidn., a highly active cobalt oxide catalyst ...
A miniaturized polymer electrospray-type interface is used to study metal-ion chelation with model peptides. Taking advantage of the intrinsic electrochemical behavior of electrospray, a sacrificial electrode is used to generate at the same time electrospr ...
A new parameter, the normalized current efficiency for the electro-combustion has been considered. This parameter allows to eliminate the mass transfer inefficiency and then can be defined as the ability of the anode to promote the electro-oxidn. and to re ...
Aluminum is produced by the electrolytic reduction of alumina dissolved in molten cryolite. This process requires carbon anodes which are consumed during the electrolysis. The anodes contribute roughly with 15% to the total aluminum production cost. If the ...
The fabrication, characterization and application of polyimide-based flexible microelectrodes for recording from and stimulation of biological tissue are described. The planar electrodes consist of a polyimide-platinum-polyimide sandwich structure with a t ...
Rotation anisotropy by second harmonic generation (SHG) is carried out on epitaxial Hg1−xCdxTe (MCT) and oxide- and sulphide-covered MCT surfaces and shows the fourfold symmetry pattern expected from the {100} surface (C4v symmetry). The uneven nature of t ...
Ozone prodn. in 5M H2SO4 with Ti/IrO2/SnO2 - Sb2O5 electrodes was studied. Electrodes were prepd. at 550 Deg by spray pyrolysis of a soln. of precursors contg. tin and antimony chlorides. The aim of this work was to elucidate the mechanism of activation an ...
The electrochem. oxidn. (or combustion) of orgs. with simultaneous oxygen evolution has been investigated using different oxide electrodes. A simplified mechanism for the electrochem. oxidn. of orgs. is presented, according to which selective oxidn. occurs ...
A dimensionally stable anode with enhanced durability for use in electrochem. processes (e.g. those involving evolution of Cl2 or O2) is described. The anode consists of a substrate of >=1 metals or metal oxides provided with an outer Ta surface coated wit ...
