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 hydrogeological study of the crystalline aquifers of the Mont-Blanc and the Aiguilles Rouges massifs is part of the AQUITYP project, which has been carried out at the Geology Laboratory of the Swiss Federal Institute of Technology, Lausanne (GEOLEP). ...
Bromine contg. compds. are thought to play an important role in the O3 destruction in various regions of the atm. Recent studies of atm. Br chem. suggest that HOBr is one of the important Br compds. The rapid photolysis of HOBr in daytime releases Br atoms ...
The inertness and unique electrochem. properties of diamond present great potential for a variety of applications in aggressive environments. Preliminary results showed the widest known electrochem. window before water decompn., allowing new possibilities ...
New mercury organic compounds with 1-3 metal centers and different substituents were synthesized as anion-selective ionophores. They were incorporated into solvent polymeric membranes, and the selectivity, slope of response, response time, emf repeatabilit ...
Boron doped diamond films have been deposited by large area hot-filament CVD (HFCVD) on silicon, silicon carbide, and different industrial electrode materials, like niobium, tantalum, titanium, tungsten, zirconium, and graphite on areas up to 40 cm * 60 cm ...
The fabrication, characterization and application of polyimide-based flexible microelectrodes for recording from and stimulation of biological tissue are described. The planar electrodes consist of a polyimide-platinum-polyimide sandwich structure with a t ...
Poly(tetrafluoroethylene) (PTFE) films were surface-modified by employing a reaction solution of benzophenone and sodium hydride in anhydrous dimethylformamide at a temperature of 150 degrees C for 12 h. Electron spectroscopy for chemical analysis (ESCA) s ...
A thermodynamic theory is used to calculate the dielectric properties of epitaxial thin films grown on cubic substrates imposing biaxial tension on the film prototypic cubic state. For such "tensile" substrates, the theory shows that, in a conventional pla ...
We have designed and realised a new type of microsystem for the electrical characterisation of arrays of living cells for biomedical diagnostic purposes. We have used deep plasma etching for the fabrication of microholes and micro-fluidic channels in silic ...
Full-scale ozonation processes for drinking water production were characterized with a conservative (sodium chloride) and two reactive tracers (ozone, aqueous chlorine) to yield information about the hydraulics and the oxidation capacity with respect to or ...
