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.
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 ...
A novel C-Nafton/Fe-ion structured fabric capable of mediating Orange II decomposition in Fenton-immobilized photoassisted reactions is presented. The catalyst preparation requires the right balance between the amount of the Nafion necessary to protect the ...
The self-assembly mechanism has been studied in poly(γ-benzyl-L-glutamate)-poly(ethylene glycol)-poly(γ-benzyl-L-glutamate) (PBLG-PEG-PBLG) triblock copolymer melts using X-ray scattering, polarizing optical microscopy, differential scanning calorimetry, a ...
We investigated the condensation of calf thymus DNA by amphiphilic polystyrenem-b-poly(l-lysine)n block copolymers ( PS m -b- PLys n , m, n = degree of polymerization), using small-angle X-ray scattering, polarized optical microscopy and laser scanning con ...
The microstructure, chemical and phase composition of the hard Ni-P-Ti layer formed on the Ti-6Al-4V alloy after duplex surface treatment were investigated by light microscopy, X-ray diffraction, scanning electron microscopy and analytical/high-resolution ...
The controlled tuning of the characteristic dimensions of two-dimensional arrays of block-copolymer reverse micelles deposited on silicon surfaces is demonstrated. The polymer used is polystyrene-block-poly(2-vinylpyridine) (91500-b-105000 g mol–1). Revers ...
The self-assembly in aqueous solution of hybrid block copolymers consisting of amphiphilic ?-strand peptide sequences flanked by one or two PEG chains was investigated by means of circular dichroism spectroscopy, small-angle X-ray scattering, and transmiss ...
We present an extremely versatile method for the lateral organization of nano-scale objects (NOs) based on the phenomenon of polymer demixing. NOs are suspended in a soln. of two immiscible polymers, which is used to form a thin polymer film by spin coatin ...
In this study a novel approach for the coating and functionalization of substrates for cell culture and tissue engineering is presented. Glass, silicon, and titanium panes were coated with an ultrathin film (30 ± 5 nm) of reactive star-shaped poly(ethylene ...
