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 sandwich mixer consists of mixing two solutions in a channel, one central laminar flow being sandwiched between two outer flow solutions. The present numerical study considers the convection– diffusion of two reacting species A and B, provided respective ...
The goal of the present study was to assess the possibility to change the composition of a calcium phosphate scaffold from a high-temperature phase to a phase only stable at or close to room temperature without macrostructural changes. For that purpose, ma ...
On-line electrogeneration of mass tags in a microspray emitter is used to quantify the number of cysteine groups in a given peptide. A finite-element simulation of the multi-step process yields the relative distribution and concentration of tags, untagged ...
The present thesis work concerns the preparation and optionally site selective functionalization of five- and six-membered nitrogen heterocycles and the investigation of atropisomerism of α,o-bis(methoxymethyl)-1-phenylindole. Mono- and disubstituted 2-bro ...
The use of zeolites for catalytic reactions is a field in continuous development. Since it was demonstrated that metal-zeolites are efficient catalysts for NOx abatement, decomposition of nitrous oxide (N2O) over Fe-containing zeolites has attracted great ...
A classification methodology for the automatic detection of start- and endpoints of chemical and biotechnological reaction systems from spectral reaction data is proposed. In the calibration phase, several batch experiments must be conducted covering the e ...
In accordance with the concept of regioexhaustive functionalization, both 3-chloro-2-(trifluoromethyl)pyridine and 2-bromo-6-(trifluoromethyl)pyridine were converted each time into the three possible carboxylic acids. 2-Bromo-4-(trifluoromethyl)pyridine, 2 ...
Catalytic hydroformylation of olefins has been carried out in a HP FT-IR cell using RhH(CO)(PPh3)(3) catalytic precursor. A different behaviour was noticed between a terminal (hex-1-ene) and an internal alkene (cyclohexene) and different rate-determining s ...
To demonstrate the superiority of modern organometallic methods, the inexpensive starting material 1,3-difluorobenzene has been selectively converted into the three benzoic acids and all seven bromobenzoic acids contg. the two fluorine atoms in homovicinal ...
Mono- and disubstituted 2-bromo-3-fluoroquinolines are readily accessible. They can be converted into the 3-fluoroquinoline-2-carboxylic acids by consecutive halogen/metal permutation and into the 2-bromo-3-fluoroquinoline-4-carboxylic acids by consecutive ...
