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.
The ability to couple high-resolution specimen imaging with chemical state analysis allows problems in biology and medicine to be approached in a novel and powerful way. Element specific chemical state analysis can be performed at tunable synchrotron X-ray ...
In situ Fourier transform infrared (FTIR) absorption spectroscopy has been used to determine the fractional depletion of silane in a radio-frequency (ri) glow discharge. The technique used a simple single-pass arrangement and was implemented in a large-are ...
We report on the direct absorption measurement of the polarization selection rules in a V-groove QWR waveguide. Attenuation measurements in a 1 mm long waveguide were performed from 10 K up to room temperature. These measurements yielded the QWR DOS select ...
In situ Fourier transform infrared absorption spectroscopy has been used to study the composition of particles formed and suspended in radio-frequency discharges of silane-oxygen-argon gas mixtures. The silane gas constumption was observed by infrared abso ...
Infrared (IR) absorption spectroscopy and mass spectrometry have been simultaneously applied to dusty radiofrequency (RF) plasmas in methane, acetylene and ethylene. The combination of IR absorption spectroscopy and mass spectrometry allows the chemical co ...
In order to understand better the mechanism of action of a permanent modifier based on Ir deposited on graphite furnaces pretreated by carbide-forming elements (W and Zr) an XPS investigation was carried out on samples submitted to thermal treatment simula ...
The integrated absorption of the b1 - X transition of the Me radical (2160 .ANG.) and the B - X transition of the allyl radical (2100-2400 .ANG.) were compared, in the flash photolysis of 1-butene. From the f value of the Me band, the oscillator strength o ...
