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.
We have investigated different possible mechanisms for the cis-trans isomerization in triply bonded ditungsten complexes with stoichiometry W2Cl4(NHEt)2(PMe3)2 using static d. functional calcns. as well as Car-Parrinello simulations. Our studies reveal an ...
Interaction of V2O5 with TiO2 during prepn. of V/Ti-oxide catalysts via solid-state reaction was studied using in situ FT-Raman spectroscopy, HRTEM and XPS. This interaction results in the formation of monomeric vanadia species with vanadium in tetrahedral ...
Using a rheometer coupled with a UV-light generator, a photo-rheometry set-up has been developed to study the viscoelastic properties of UV-coating systems during fast curing. Due to a high reaction rate, the viscoelastic properties have to be evaluated us ...
The possibility of enhancing reactor performance under forced cycling of the inlet feed was investigated for the ethanol to ethene dehydration reaction over gamma-alumina. This reaction presents a stop-effect, i.e. a drastic increase of the reaction rate f ...
The gasification reaction of fir charcoal with CO2 was studied by isothermal thermogravimetric analysis under kinetic control. The derived reaction rate (r = dX/dt) as a function of the converted carbon mass (X) was compared with random pore model predicti ...
This paper deals with the kinetic study of bulk free radical polymerization of styrene initiated with the commercial bifunctional initiator 2,5-dimethyl-2,5-bis(2-ethyl hexanoyl peroxy)hexane (Lupersol 256). The polymerization kinetics is investigated by D ...
A novel liquid system has been developed to initiate the anionic polymerization of lactam-12. This system, containing both an activator and a catalyst, has the primary advantage over previous systems of permitting infinite storage of the reactant, and it a ...
A new chem. crosslinking scheme was utilized for the formation of degradable poly(ethylene glycol) hydrogels suitable for the delivery of protein drugs. An aq. soln. contg. a PEG-multiacrylate and solid particles of albumin was mixed with an aq. soln. cont ...
The reaction rate, the catalyst potential, the catalyst work function and the voltammetric charge were in situ measured during a galvanostatic transient of ethylene combustion on an IrO2 catalyst at 380 Deg. The catalytic activity of an IrO2 catalyst could ...
A device for the preventative photodynamic therapy of secondary cataract has been developed. Disturbance of the epithelial cells of the crystalline lens during the primary cataract surgery and/or their migration thereafter can frequently generate secondary ...
