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 main obstacles in the widespread use of hydrogen as energetic alternative to fossil fuels are storage problems intrinsically linked to its extremely light and explosive nature. Since no ideal storage systems currently exist, reversible fixation of hydr ...
The introduction of hydrogen in transport, particularly using fuel cell vehicles, faces a number of technical and non-technical hurdles. However, their relative importance is unclear, as are the levels of concern accorded them within the expert community c ...
Amorphous and microcrystalline silicon have been proven to be very interesting for low cost thin film photovoltaic devices. Usually these two materials are deposited using the same large area plasma-enhanced chemical vapor deposition reactors from silane a ...
We demonstrate that the giant spin contrast observed by scanning tunneling microscopy for double-layer Coislands on Pt(111) is caused by adsorbates at the apex of the Cr-coated W tip. The most likely candidate, in ab initio simulations, is hydrogen. Here, ...
This project aims to analyze, fabricate and characterize a mechanical hydrogen sensor. The potential of hydrogen gas detection using beam resonators is investigated. The beams consist mainly of Si3N4, providing a tensile stress to prevent buckling. Pd expa ...
We characterize a novel orthorhombic phase (gamma) of NaAlH4, discovered using first-principles molecular dynamics, and discuss its relevance to the dehydrogenation mechanism. This phase is close in energy to the known low-temperature structure and becomes ...
The goal of this project would be to study the thermochemical production of hydrogen by using woody biomass as a raw material. The thermo-economic performance of the process will be evaluated and an optimisation will be performed to define the optimal syst ...
The present invention relates to a method of producing hydrogen gas and carbon dioxide in a catalytic reaction from formic acid, said reaction being conducted in an aqueous solution over a wide temperature range and already at room temperature (25 DEG C). ...
Hydrogen prodn. using earth abundant metals is one of the important challenges facing an energy economy based upon solar fuels. Schemes that incorporate the photo-oxidn. of water must also include schemes for efficiently converting released protons and ele ...
A homogenous catalytic system has been developed that efficiently and selectively decomposes formic acid into hydrogen and carbon dioxide. [Ru(H2O)6]2+, [Ru(H2O)6]3+ and RuCl3·xH2O are all excellent precatalysts in presence of TPPTS (TPPTS=meta-trisulfonat ...
