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.
Highly structured fluorescence is reported for C60 mols. isolated in Ne and Ar matrixes. Their excitation spectra are similar to the gas-phase 2-photon ionization spectrum of C60. Most of the bands seen in emission can be attributed to Herzberg-Teller or J ...
An excellent knowledge of histopathological risk factors of superficial bladder transitional cell carcinoma is mandatory to establish the prognosis of the disease. Presence or absence of carcinoma in situ (CIS) in superficial bladder cancer is one of the m ...
Absorption, emission and fluorescence-excitation spectra are reported for Hg atoms and Hg2 mols. in Ar, Kr, Xe and N2 matrixes upon excitation by synchrotron radiation in the 260-90 nm range. The fluorescence emitted from all levels issued from the 6s6p co ...
The variations of reflection and transmission coefficients, as well as of the fluorescence response of the arterial wall are studied as a function of temperature. In a first experiment, reflection coefficient, transmission coefficient, and temperature, are ...
Clinical results obtained endoscopically with an imaging fluorescence photodetection apparatus based on the use of one excitation wavelength and detection of the fluorescence emission performed in two separate spectral windows are presented. Early cancer p ...
In vivo spectrofluorometric analysis represents a tool to obtain information about fluorophore distribution in tissue. Based on a Peltier-cooled CCD we designed a fluorescence excitation and emission spectrograph which allows to obtain tissue spectra endos ...
Fluorescence lifetime imaging (FLI) is increasingly recognized as a powerful tool for biochemical and cellular investigations, including in vivo applications. Fluorescence lifetime is an intrinsic characteristic of any fluorescent dye which, to a large ext ...
We report the measurement of seven rovibronic bands belonging to the C3-PI-(v' = 0-6)-X3-PI-(v" = 0) transition in SiC. The molecules are produced by laser vaporization in combination with supersonic cooling and the transitions are detected using pulsed la ...
A process for increasing the fastness to light, the fluorescence polarisation and fluorescence quantum yield of cyanine dyes, which process comprises stabilising cyanine dyes with the aid of micellar structures of a) surfactants and/or b) surfactant cro ...
