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 performance of the electrolytic ozone generation using a solid polymer electrolyte (SPE) and Pb anode is described. This anode has been prepd. by application of Pb powder on a porous Ti substrate coated with IrO2 layer (Ti/IrO2/Pb anode). Electrochem. ...
Electrochem. insertion of lithium in nanoporous and CVD samples of anatase was studied by chronoamperometry. The currents following cathodic and anodic potential steps were monitored as a function of film thickness, temp., and electrolyte concn. The time d ...
Among the numerous base metals tested for DSA type electrodes (e.g., titanium and its alloys, zirconium, niobium etc.), tantalum is a potentially excellent substrate owing to its good elec. cond. and corrosion resistance, and the favorable dielec. properti ...
This work contributes to the generalization of the Non-faradaic Electrochemical Modification of Catalytic Activity effect, known under the acronym NEMCA. This effect is observed for the first time over an oxide catalyst, namely IrO2 supported on yttria-sta ...
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 ...

A theor. model describing the electrochem. oxidn. of orgs. at oxide electrodes (MOx) forming the higher oxide (Mox+1) is described. In this model, both orgs. and O2 evolution are mediated by the higher oxide (MOx+1) which is electrogenerated at the anode s ...
Several bottom electrode systems for ferroelectric thin film deposition onto reactive substrates or reactive metal films have been investigated with respect to chemical barrier properties and contact resistivity. Such electrode systems should not deteriora ...
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 ...
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 ...
