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.
Natural gas is defined as a combustible mixture of hydrocarbons coming from ground deposits and it is mainly used as a source of energy for burners and motors. Its consumption is increasing worldwide, as this represents a cheap and abundant source of energ ...
Associated gases at oil wells are often rich in heavy hydrocarbons (HHC, here denoting hydrocarbons heavier than methane). HHC may cause handling and combustion difficulties as their properties are different from standard natural gas, therefore HHC rich as ...

Prof. Laloui discussed some of the major challenges facing CO2 geosequestration, a technology which could be vital in Switzerland’s transition away from nuclear as this may mean increased reliance on natural gas. Many of these challenges, such as cap rock ...
An exergy and environmental comparison between the fuel production routes for Brazilian transportation sector, including fossil fuels (natural gas, oil-derived products and hydrogen), biofuels (ethanol and biodiesel) and electricity is performed, and the p ...
Before 2013, it was widely believed that China's shale gas resources could radically alter the dynamics of supply for the world's biggest energy consumer, and there would be a shale gas boom in China, for two major reasons: China has a policy of encouragin ...

Thermoeconomics is a discipline that connects Thermodynamics and Economics concepts, usually used for rational cost assessment partition to the final products of a thermal plant, by means of a model that describes the cost formation process of the overall ...
In the past years, transport of gases in clay buffer materials for Engineered Barrier Systems (EBS) has been deeply investigated by many research programs in the field of nuclear waste disposal. The phenomenological features of gas transport obtained from ...
We introduce luciferases whose emission maxima can be tuned to different wavelengths by chemical labeling. These tunable luciferases are generated by inserting the small luciferase NanoLuc into the structures of the self-labeling proteins SNAP-tag or HaloT ...
Recent studies have shown that exposure to particulate black carbon (BC) has significant adverse health effects and may be more detrimental to human health than exposure to PM2.5 as a whole. Mobile source BC emission controls, mostly on diesel-burning vehi ...
In the power generation sector, substituting fossil-fuels with near-zero carbon alternatives is one viable option identified for curbing CO2 emissions. Solar energy is one such alternative and it's valued for being inexhaustible in nature. This study exami ...
