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.
A four-wavelength low-power continuous-wave frequency laser reference system has been realised in the 935.4-nm range for water vapour differential absorption lidar (DIAL) applications. The system is built around laboratory extended-cavity and DFB diode las ...
Infrared spectroscopy using semiconductor lasers is a promising technique for trace gas detection. It allows a continuous and real time monitoring of several species, with a high sensitivity and a good selectivity. Among all the possible methods two are pa ...
The formation of sub-micron sized particulates has been studied in a low pressure (0.1 mbar) radio-frequency (13.56 MHz) capacitively coupled plasma discharge. Particles are studied in situ by infrared absorption spectroscopy, laser illumination and Cavity ...
We calc. the effects of relatively strong elec. fields, corresponding to typical values for the fields inside glasses and proteins, on the spectroscopic properties of a simple two-level mol. Disorder in the elec. field strength is employed as a phys. sourc ...
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 electropolymn. of Ru and Os bis-terpyridine complexes that form rodlike polymers with bithienyl, quaterthienyl, or hexathienyl bridges were studied. Absorption spectroscopy, SEM, and cyclic voltammetry were used to characterize the monomers and resulti ...
In the moderate magneticfield of TCV (1.5T), the recently installed X3 system (3 gyrotrons @118 GHz, 0.45 MW/each, 2s) broadens the operational space with the possibility of heating plasmas at high density, well above the cutoff density of the X2 system (X ...
The photochem. of ICN isolated in Ar matrixes has been investigated using UV absorption and laser spectroscopy under a variety of exptl. conditions. Laser excitation of the repulsive ~A continuum gives rise to long-lived near-IR emission from stabilized I ...
The new dye complex bis[4,4'-di(2-(3-methoxyphenyl)ethenyl)-2,2'-bipyridine][4,4'-dicarboxy-2,2'-bipyridine]ruthenium(II) dihexafluorophosphate (1) was prepd., characterized by absorption spectroscopy and adsorbed onto nanocryst. TiO2 electrodes. The resul ...
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 ...
