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.
The present paper reviews existing knowledge with regard to Organic Aerosol (OA) of importance for global climate modelling and defines critical gaps needed to reduce the involved uncertainties. All pieces required for the representation of OA in a global ...
Atmospheric aerosol is defined as a suspension of solid or liquid particles in air. The major concerns about aerosol particles are their adverse health effects and their role in the Earth's climate system. Atmospheric particles influence the Earth's radiat ...
The aerosol water content and volumetric growth factors of fine particulate matter were measured during July-August 2001 and January-June 2002 in an urban park about 6 km from downtown Pittsburgh, Pennsylvania. Most of the aerosol during the study was tran ...
The concentration and chemical composition of ambient fine particulate material (PM2.5) is reported for two sampling sites in the Pittsburgh, Pennsylvania metropolitan area: the Department of Energy, National Energy Technology Laboratory (NETL) PM study si ...
A new aerosol model, the Model of Aerosol Dynamics, Reaction, Ionization, and Dissolution (MADRID) has been developed to simulate atmospheric particulate matter (PM). MADRID and the Carnegie-Mellon University (CMU) bulk aqueous-phase chemistry have been in ...
The electrochem. prepn. of ceric sulfate [13590-82-4] was studied in concd. H2SO4 (10 mol/dm3). The current efficiency of the reaction increases considerably if a mixed catalyst (Ag2SO4 + MnSO4) is used. [on SciFinder (R)] ...
The ene reaction of sulfur dioxide with enoxysilanes or with allylsilanes generates silyl sulfinates that can be brominated (Br-2 or NBS) or chlorinated (NCS or Cl-2) to produce the corresponding sulfonyl halides. They react with primary and secondary amin ...
As other monosaccharide mimics such as the azasugars and the carbasugars (with nitrogen and carbon atom, respectively, instead of oxygen atom in the ring) the thiosugars (with sulfur atom instead of oxygen atom in the ring) have gained importance in glycob ...
Formaldehyde is a primary and secondary air pollutant. As an intermediate product of hydrocarbon photooxidn., it contributes to the formation of photochem. pollution in urban areas. In addn., chronic or acute exposure to HCHO (a possible carcinogen) consti ...
Oxidative potential (OP), which is the ability of certain components in atmospheric particles to generate reactive oxidative species (ROS) and deplete antioxidants in vivo, is a prevailing toxicological mechanism underlying the adverse health effects assoc ...
