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.
With the current concerns about sustainable development and greenhouse gas emissions in various fields, the road domain has also to contribute. Indeed, asphalt mixture production is a very important energy consuming phase in order to heat the aggregates an ...
The project is dealing with the influence of private actors on climate policy, namely the influence of business on Swiss climate policy. The project uses a case study, assessing the voluntary agreements concluded between the federal government and the asso ...
The present invention relates to a method for a low cost Planet vector Sensor based on imaging atmospheric oxygen emission at 762 nm or at 557.7 wavelengths using either CMOS, CCD or arrays of single photon avalanche diodes (SPADs). In both daytime and nig ...
Air quality transcends all scales with in the atmosphere from the local to the global with handovers and feedbacks at each scale interaction. Air quality has manifold effects on health, ecosystems heritage and, climate. In this review the state of scientif ...
We report the first joint shipboard and airborne study focused on the chemical composition and water-uptake behavior of particulate ship emissions. The study focuses on emissions from the main propulsion engine of a Post-Panamax class container ship cruisi ...
A novel ignition concept based on autoignition in an unscavanged prechamber is currently being developed at the Laboratory for Industrial Energy Systems (LENI). On a single cylinder test engine a series of experimental runs (CR=8.5-14, =1-1.6, RPM=1150/150 ...
Tropospheric ozone (O3) is a harmful pollutant and an increasingly important green-house gas. Tropospheric O3 distributions are determined by complex and non-linear interactions between photochemistry and transport processes. The first objective of this th ...
Gallium nitride (GaN) is one of the most interesting materials for devices applications such as blue light emitting diodes, laser diodes and high power and high temperature electronic applications, because of its large band gap (3.39 eV). Several growth te ...
Cysteine stabilized ZnS and Mn2+-doped ZnS nanoparticles were synthesized by a wet chemical route. Using the ZnS:Mn2+ nanoparticles as seeds, silica-coated ZnS (ZnS@Si) and ZnS:Mn2+ (ZnS:Mn2+@Si) nanocomposites were formed in water by hydrolysis and conden ...
We examine the response of Arctic gas and aerosol concentrations to perturbations in pollutant emissions from Europe. East and South Asia, and North America using results from a coordinated model intercomparison. These sensitivities to regional emissions ( ...
