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.
A series of poly(ethylene glycol-co-isopropylidene glyceryl glycidyl ether) (P(EO-co-IGG)) random copolymers with different fractions of 1,2-isopropylidene glyceryl glycidyl ether (IGG) units was synthesized. After acidic hydrolysis a new type of "function ...
This manuscript reports a facile strategy for the modification of polyethylene, a widely used biomaterial, with a thin non-biofouling coating that can act as a platform to introduce biochemical cues to control and direct, e.g., cell adhesion and proliferat ...
Nonfouling coatings, based on surface-tethered, hydrophilic polymer chains, have widespread application in areas such as biosensing, medical devices, and biotechnology. Self-organization of polymers is a particularly attractive approach given its simplicit ...
The synthesis and evaluation of new dopamine-based catechol anchors coupled to poly(ethylene glycol) (PEG) for surface modification of TiO2 are reported. Dopamine is modified by dimethylamine-methylene or trimethylammonium- methylene groups, and the prepar ...
The photoexcitation and photoionization dynamics of sodium atoms deposited on the surface of helium nanodroplets and aromatic molecules (aniline, phenol and toluene) embedded in the interior of droplets have been investigated by a variety of spectroscopic ...
CsI thin film photocathodes of 600 nm thickness deposited on polished Al surfaces by resistive evaporation technique were studied by angle-resolved X-ray photoelectron spectroscopy (ARXPS), before and after UV-irradiation under vacuum. It is shown that the ...
Benzo-15-crown-5 functionalized polymer brushes prepared via surface-initiated atom transfer radical polymerization are used as the active layer in a potassium-selective quartz crystal microbalance sensor. The polymer brushes allow the selective detection ...
Hydrolytically degradable polymer brushes would represent an interesting platform for the development of functional coatings for various biomaterials applications In this manuscript, the surface- initiated atom transfer radical copolymerization of 5.6-benz ...
Two novel tetra- and hexahydroxy functionalized perylene chromophores have been used as initiators for the Sn(oct)2 catalyzed ring-opening polymerization of different lactones. The arms of the resulting star polymers were comprised of either crystallizable ...
The surface electronic and mol. structure of a new org. chromophore useful for dye-sensitized nanostructured solar cells was studied by electron spectroscopy. Initially the use of a simple mol. system contg. the polyene-diphenylaniline chromophore in a sol ...
