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.
This study focuses on an interesting and important phenomenon that was employed in a new approach to laser isotope separation that has been recently proposed and developed in our laboratory for highly selective separation of carbon isotopes. This approach ...
The identification of phosphorylation sites in proteins provides a powerful tool to study signal transduction pathways and to establish interaction networks involving signaling elements. Using different strategies to identify phosphorylated residues, we re ...
A series of controlled laboratory experiments are carried out in dual Teflon chambers to examine the presence of oligomers in secondary organic aerosols (SOA) from hydrocarbon ozonolysis as well as to explore the effect of particle phase acidity on SOA for ...
Carotenoid prodn. by microorganisms, as opposed to chem. synthesis, could fulfill an ever-increasing demand for 'all natural' products. The yeast Phaffia rhodozyma has received considerable attention because it produces the red pigment astaxanthin, commonl ...
In the pursuit of a portable gas detector/analyser we studied the components of an ion mobility spectrometer (IMS), which is a device that lends itself well to miniaturisation. The component we focused on was the ionizer. We fabricated a series of micro io ...
Electrospray ionization mass spectrometry of neat ionic liquids does not require continuous sample injection and the presence of a molecular solvent facilitates analysis of the ionic liquid itself and dissolved analytes. ...
In the present work, herbicide 2,4,5-trichlorophenoxyacetic acid, more commonly known as 2,4,5-T herbicide, has been completely mineralized (i.e. transformed into CO2 and H2O) in satd. aq. solns. using a semi-industrial electrochem. cell that contains a bo ...
Spatial representativeness is an important quality criterion in trace gas monitoring, especially if measurements are intended for regulatory and model validation purposes. Open-path absorption spectroscopy techniques meet the representativeness requirement ...
The fate of melamine has been studied under UV light irradiation (medium pressure mercury arc) in the presence of TiO2 and H2O2. The increase in the concentration of aromatic and aliphatic photo-products were determined in solution concomitantly with the d ...
We present results obtained from modeling the septum assessment experiments of the JET MkIIGB divertor with the B2-Eirene code package. Similar L-mode discharges have been performed with and without septum, varying density and gas puffing location. High an ...
