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.
This paper discusses the role of actors in the transition towards an energy self- sufficient region in Güssing, Austria. Regions with the vision of energy self-sufficiency are often called “energy regions”. We identify and describe the states, phases and m ...
Since its emergence as a field, optofluidics has developed unique tools and techniques for enabling the simultaneous delivery of light and fluids with microscopic precision. In this Review, we describe the possibilities for applying these same capabilities ...
The electrochemical oxidation of ammonia (NH4+/NH3) in sodium perchlorate was investigated on IrO2 electrodes prepared by two techniques: the thermal decomposition of H2IrCl6 precursor and the anodic oxidation of metallic iridium. The electrochemical behav ...
This study investigates the performance of a standard Ni-YSZ anode supported cell under ethanol steam reforming operating conditions. Therefore, the fuel cell was directly operated with a steam/ethanol mixture (3 to 1 molar). Other gas mixtures were also u ...
A review on some of the key aspects of photovoltaic (PV) technol. and the ongoing effort to exploit the planet's largest energy source. It focuses on the inorg. materials: the core of current and developing PV technol. and a research area crucial to the fu ...
A new water-soluble methyl-imidazolium-based ionic polymer was synthesized by ring-opening metathesis polymerization that was subsequently used to prepare aqueous gold nanoparticle solutions which were characterized by UVvis spectroscopy and transmission e ...
Platinum catalyst dissolution with subsequent reduction and deposition of Pt particles in the membrane can lead to a significant loss of polymer electrolyte fuel cell (PEFC) performance. To quantify the amount of deposited platinum, a novel transmission el ...
Miniaturizing dielectric electroactive polymer (EAP) actuators will lead to highly-integrated mechanical systems on a chip, combining dozens to thousands of actuators and sensors on a few cm2. We present here µm to mm scale electroactive polymer (EAP) devi ...
Today, energy saving is one of the main objectives for engineers. In the case of mobile applications, energy can be saved by two different ways. First, decreasing the total masse of the system, and second, increasing the efficiency of the overall system. T ...
Solid Oxide Fuel Cell systems (SOFC) are developed for their electrical efficiency and versatility. Versatility stems from their tolerance towards CO and CH4, which allows for the use of various reformed fuels. Efficiency results from the direct conversion ...
