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.
The solubility of alkylthiol-coated silver nanoparticles and the energetics of the ligand disordering have been investigated. Calorimetry measurements have provided correlations between the nature of the ligands and the enthalpy of the ligand disordering, ...
The sorption and desorption of poly(vinylpyrrolidone)-Se-0 (PVP-Se-0) nanoparticles on gel films of cellulose Acetobacter xylinum (CAX) are investigated. It is revealed that the hydrodynamic radius R (h) of PVP-Se-0 nanoparticles decreases from 57 nm in th ...
Time resolved optical Kerr effect measurements have been used to det. the orientational dynamics of water in the pores of ZrO2 nanostructured films. We demonstrate that local heating effects can safely be ignored and present our results which are manifestl ...
In this study, we characterize the CCN activity of the water-soluble organics in biomass burning aerosol. The aerosol after collection upon filters is dissolved in water using sonication. Hydrophobic and hydrophilic components are fractionated from a porti ...
A new transformation based on the Staudinger reaction is described, and its application in the design of a novel switch element to control peptide folding is demonstrated. We found that the azide switch is activated rapidly in water to promote acyl transfe ...
We present an experimental and theoretical study on the optical properties of arrays of gold nanoparticle in-tandem pairs (nanosandwiches). The well-ordered Au pairs with diameters down to 35 nm and separation distances down to 10 nm were fabricated using ...
Nanoparticles can be stabilized by an ionic liq. polymer (ILP) composed of imidazolium units incorporating a hydrophobic benzyl group. The resulting gold, platinum, and palladium nanoparticles can be efficiently transferred from water to ionic liqs. by exc ...
The biphasic hydrosilylation of 1-hexadecene with siloxane B9800 in a range of ionic liqs. is reported. Of the ionic liqs. tested, [C4py][BF4] and [C4-3-pic][BF4] offer the optimum compromise between activity and ...
Tris(β-diketonato)europium(III) with a series of variably fluorinated ligands derived from 3,5-heptanedione were synthesised with the aim of determining their hydration state under extraction conditions. The number of coordinated water molecules was determ ...
We report the filling kinetics of different liquids in nanofabricated capillaries with rectangular cross-section by capillary force. Three sets of channels with different geometry were employed for the experiments. The smallest dimension of the channel cro ...
