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.
Block-copolymer templating of inorg. frameworks provides a powerful route to produce periodic nanoporous materials with well-defined nanoscale architectures, controlled porosity, and high surface area. Such control is important for batteries and pseudocapa ...
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 ...
This project involved the conversion of a British Waterways maintenance craft to a canal boat, powered by a combination of a solid-state hydrogen store, Proton Exchange Membrane (PEM) fuel cell, lead-acid battery pack and a high-efficiency, permanent magne ...
The weakness of nickel-based solid oxide fuel cell anodes is their low ability to withstand re-oxidation at working temperature, especially for the anode-supported cell design. The volume expansion coming along with nickel (Ni) oxidation induces stresses i ...
We propose a simple microfluidic device for protein preconcentration based on the electrokinetic trapping principle. It comprises a narrow Nafion strip that is simply cut from a commercial membrane and is integrated into a molded poly(dimethylsiloxane) (PD ...
Vanadium redox flow batteries (VRB) are large stationary electricity storage systems with many potential applications in a deregulated and decentralized network. Flow batteries (FB) store chemical energy and generate electricity by a redox reaction between ...
The prerequisite for widespread use of hydrogen as an energy carrier is the development of new materials that can safely store it at high gravimetric and volumetric densities. Metal borohydrides M(BH 4) n (n is the valence of metal M), in particular, have ...
A hydrogen sensor based on a novel fabrication process that combines the precision of advanced nano-fabrication techniques with a bottom-up process based on electrochemistry is presented. The sensor allows for reliable detection between 0.1% and 100% of H2 ...
The fundamental aspects of electrochemistry at liquid–liquid interfaces are introduced to present the concept of molecular electrocatalysis. Here, a molecular catalyst is adsorbed at the interface to promote a proton coupled electron transfer reaction such ...
A method to create an array of sub-5 nm nanogaps with self-aligned holes in a protective polymer overlayer is presented. The parallel formation of the nanogaps, intended for electrical sensing of biomolecules in an aqueous environment, is achieved by elect ...
