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.
During the past decades the field of sensors has been subject to much attention due to an increased demand for (bio)sensors and environmental monitoring. The efforts have been concentrated to create sensors which are reliable, highly sensitive and selectiv ...
Quantum mechanics/molecular mechanics (QM/MM) Car-Parrinello simulations were performed to estimate the coordination numbers of K+ and Na+ ions in the selectivity filter of the KcsA channel, and in water. At the DFT/BLYP level, K+ ions were found to displa ...
While the bulk structure of a material determines its mechanical properties, its surface plays a key role when interactions with the environment are important. Nowadays materials in bio- and nanotechnology are required to possess very complex functionaliti ...
This manuscript reports on the post-polymerization modification of poly(glycidyl methacrylate) (PGMA) and PGMA-co-poly(2-(diethylamino)ethyl methacrylate) (PGMA(x)-co-PDEAEMA(y)) (co)polymer brushes prepared via surface-initiated atom transfer radical poly ...
The term polymer brush refers to a well defined arrangement of polymer chains, which are tethered with one end to an interface and usually the surface of a solid substrate. Due to steric repulsion the polymer chains furthermore adopt a defined, stretched c ...
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 ...
Hydrophilic polymer brushes grown via surface-initiated ATRP from silicon oxide surfaces are susceptible to detachment via hydrolytic cleavage of the anchoring siloxane bond. This paper investigates the influence of the structure of the ATRP initiator on t ...
Trinuclear metallamacrocycles can be obtained by reactions of (arene)Ru, CpRh and CpIr complexes with pyridonate ligands. Using 3-oxy-pyridonate as the bridging ligand, organometallic analogues of 12-crown-3 are formed, which display an extremely high af ...
Clusters containing nine lanthanide and six sodium ions are crystallized with the help of a tridentate ligand bearing a phosphonic acid group; the structure of the EuIII compound reveals a host-guest assembly Eu⊂Na6Eu8L16 with a substantial quantum yield ( ...
Surface-initiated controlled radical polymerization is a powerful strategy to tailor the chemical and physical surface properties of materials. This article highlights recent work from the author's laboratory in which surface-initiated atom transfer radica ...
