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 tetragonal molybdenum nitride (beta-Mo2N) has been prepared by temperature programmed treatment of MoO3 in flowing N-2 + H-2 and for the first time shown to catalyze the liquid phase selective hydrogenation (T = 423 K; P-H2 = 11 bar) of a series of para- ...
Platinum nanoparticles (PtNPs stabilized by an ionic-liq.-like-copolymer (IP) immobilized in various ionic liqs. (ILs)) effectively catalyze the selective hydrogenation of arom. chloronitro compds. to arom. chloroamines, a reaction of considerable com. sig ...
Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...
The functionalization of nanoparticles is conditio sine qua non in studies of specific interaction with a biological target. Often, their biological functionality is achieved by covalent binding of bioactive molecules on a preexisting single surface coatin ...
The formation of complexes between nanoparticles and polyelectrolytes is a key process for the control of the reactivity of manufd. nanoparticles and rational design of core shell nanostructures. In this work, we investigate the influence of the nanopartic ...
Homochiral Diels-Alder cyclodimerization of (+/-)-6-ethenyl-7-oxabicyclo[2.2.1]hept-5-en-2-endo-ol followed by oxidation gives (1RS,4RS,4aSR,4bSR,5RS,8RS,8aRS)-8a-ethenyl-1,3,4a,4b,5,6,8,8a,9-decahyd ro-11,4:5,8-diepoxyphenanthrene-2,7-dione (18). Selectiv ...
The main objectives of this work are 2-fold : The development of a novel type of composite material based on carbon nanofibers supported on sintered metal fibers filters (CNF/SMF) and to explore the use of this material as a catalytic support for a model r ...
In this thesis, the use of nanotemplates for steering the molecular self-organization at metallic surfaces is investigated. Nanotemplates are surfaces that exhibit a periodic variation of the adhesion energy on the nanometer scale. Preferential adsorption ...
This thesis describes some of three years'work carried at the Centre Suisse d'Electronique et de Microtechnique (Neuchâtel, Switzerland) under the supervision of Dr. Martha Liley and in collaboration with Prof. Horst Vogel of the Ecole Polytechnique Fédéra ...
In recent years, a strong emphasis in research towards creating sustainable and environmental friendly chemical processes has propelled the development of novel types of catalytic systems that combine advantages from homogeneous and heterogeneous processes ...
