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.
Lignocellulose is a renewable source of fixed carbon and a promising substrate for the production of chemicals and fuels in second generation biorefineries. In this thesis, we engineered artificial microbial consortia for consolidated bioprocessing (CBP) o ...
Production of secondary aluminium (Al) currently represents about 70% of total European Al production with a still rising trend and about 50% European final Al demand. The utilization of anthropogenic Al resources as secondary raw materials is therefore a ...
Sustainable recycling of e-waste bares opportunities as well as obstacles - mainly for small and medium size enterprises. Especially the current challenging market situation for second- hand raw materials makes it difficult for small e-waste recyclers to o ...
Recycling of construction material is a valuable option for minimizing construction & demolition waste streams to landfills and mitigating primary mineral resource depletion. Material flows in the construction sector are governed by a complex socio-technic ...
The construction industry’s contribution to the deterioration of Earth’s ecosystem is huge. 11% of all anthropic greenhouse gas emissions worldwide are due to the construction, demolition, and transformation of buildings and infrastructure. Construction an ...
Narrow scrape-off layer (SOL) heat flux channel widths (λq) are seen on many tokamaks, both in inner-wall limited (IWL) and diverted discharges. These observations have important consequences for ITER and reactors, impacting the design of inner limiter til ...
Ultralow densities of crystalline nanospheres have been detected in amorphous polymer microspheres by utilizing the unique sensitivity of second-order nonlinear optical techniques to anisotropy. Vibrational sum frequency scattering (SFS) and X-ray diffract ...
In this work, the environmental impacts caused by an innovative upcycling process of printed plastic scrap have been assessed through Life Cycle Analysis (LCA) methodology for the first time. The process consists of removing the inks from the plastic surfa ...
As the end of life becoming more and more complex recycling systems encountered many difficulties in valuing all the materials contain in each product. This involves not only recovering a large number of materials but also doing so with the minimal environ ...
