Graph Chatbot
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.
Electron Beam Induced Deposition (EBID) allows deposition of three-dimensional micro- and nano-structures of conductive and insulating materials on a wide range of substrates. The process is based on the decomposition of molecules of a pre-selected precurs ...
A new protein fractionation technique based on off-gel isoelectric focusing (IEF) is presented, where the proteins are separated according to their isoelectric point (pI) in a multiwell device with the advantage to be directly recovered in solution for fur ...
The derivatization of neutral transition metal carbonyl clusters with an alkoxide anion, [Mn(CO)xOR]- is discussed. The electrospray ionization mass spectrometry technique is used for the purpose. Control of the potential applied to the skimmer cone of the ...
The anodic oxidn. of 4-chlorophenoxyacetic acid (CPA) on synthetic B-doped diamond thin film electrodes in acid media was studied, using cyclic voltammetry and bulk electrolysis. The results showed that in the potential region where the supporting electrol ...
Ionization energies (IE) of [M + zH]z+ (z+) electrospray-produced polypeptides were detd. by electron ionization in a Penning cell of 4.7 and 9.4 .T Fourier transform mass spectrometers. For z = 1+ and substance P, the found IE value of 11.0+-0.4 eV is in ...
For the development of micro gas sensors, studies of field ionization and break-down in small gaps were performed. A finite element simulation was done for an estimate of the achievable field strength near a nanotube tip in small gaps. The simulation also ...
We develop a microionizer as the ion source in a miniaturized spectrometerlike gas analyzer, operating at atmospheric pressure. Several options for the ionizing principle were considered. The application of dc glow discharge in a microsystem was studied in ...
"Thermal desorption experiments" were carried out during which heavy metal evaporation was studied by on-line monitoring. This could be achieved by the use of a tubular furnace connected to a heavy metal detector, i.e. an ICP-OES (inductively coupled plasm ...
The kinetic energy dependence of ions trapped in a radiofrequency (RF) hexapole ion trap was calcd. as a function of space charge, mean free path, mass, RF potential and charge. The av. kinetic energy of the ions increases with increasing space charge, mea ...
The Cl2 evolution reaction was studied at highly boron-doped diamond thin film electrodes. The comparison of this carbonaceous material with graphite and glassy carbon points out the similar behavior in terms of diagnostic parameters and related mechanisms ...
