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.
Water and food are basics of human life, unfortunately climate changes and water pollution have reduced the amount of water available for human uses. In this context the study of the hydrologic cycle is becoming of growing importance in order to optimize t ...
In this study we report the application of three cobalt redox shuttles in 100% aqueous electrolyte dyesensitised solar cells (DSCs). By using chloride as a counter-ion for cobalt bipyridine, cobalt phenanthroline and cobalt bipyridine pyrazole, the redox s ...
This paper addresses the synthesis problem of non-isothermal interplant water networks by using a mathematical programming approach based on superstructure optimisation. A recently proposed compact superstructure (Ibrić et al., 2015) was used and the mixed ...
This work proposes a novel approach for the simultaneous synthesis of Heat Exchanger Networks (HEN) and Utility Systems. Given a set of hot and cold process streams and a set of available utility systems (e.g., gas turbine, steam cycle, boiler, etc), the m ...
Much literature about the use of pyrolysis in the coffee production sector focuses on a stationary plant design. We evaluate the benefits of a mobile plant to also serve small coffee farmers where the harvesting season lasts only about three months. In suc ...

The fragility of thin Clark-type glass microelectrodes used in aquatic eddy covariance measurements of benthic oxygen fluxes is a challenge when using this powerful technique. This study presents a new fast-responding dual oxygen-temperature sensor for edd ...
This bachelor project work aims to set up a prototype measurement station in the Sorge (a small river near the EPFL) to collect some data about the water and the environmental conditions. And also make the work reproducible so that someone, somewhere else ...
The first step towards managing and optimising the steam network of an industrial cluster or plant is to accurately measure the production and consumption of the different levels of steam. Measurement errors as well as unmeasured contributors lead to inacc ...
Water becomes ordered in the form of hexagonal ice at room temperature under controlled humidity conditions upon confinement in the nanometer range between protective graphene sheets and crystalline (111) surfaces with hexagonal symmetry of the alkali eart ...
Process for producing a briquette containing carbon carriers (2): mixing the carbon carriers (2) together with a binder system (3) with introduction of steam and the mixture obtained is pressed to form briquettes. At least one of drying carbon carriers (2) ...
