Graph Chatbot

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.

Ab-initio Carbon Capture in Open-Site Metal Organic Frameworks

Berend Smit

During the formation of metal–organic frameworks (MOFs), metal centres can coordinate with the intended organic linkers, but also with solvent molecules. In this case, subsequent activation by removal of the solvent molecules creates unsaturated ‘open’ met ...

Convective cells and blob control in a simple magnetized plasma

Ambrogio Fasoli, Ivo Furno, Christian Gabriel Theiler, Joaquim Loizu Cisquella

Blob control by creating convective cells using biased electrodes is demonstrated in simple magnetized toroidal plasmas. A two-dimensional array of electrodes is installed on a metal limiter to obtain different biasing schemes. Detailed two-dimensional mea ...

Metal Phosphorus Complexes as Antitumor Agents

Paul Joseph Dyson, Alexey Nazarov

Phosphorus-based ligands are an extremely important class of ligand and they have found many applications, especially in homogeneous catalysis. In addition, a phosphine ligand is found in a gold drug used to treat rheumatoid arthritis. Since metal compound ...

Fatigue and cyclic creep of replicated microcellular aluminium

Andreas Mortensen, Sébastien Philippe Soubielle, Frédéric Diologent

The cyclic behaviour of 400 mu m pore size replicated aluminium foam is assessed in tension-tension fatigue with a stress ratio equal to 0.1, keeping the load amplitude constant, for relative density values comprised between 0.175 and 0.220. The number of ...

Graphene: Substrate preparation and introduction

Henning Paul-Julius Stahlberg, Radosav Svetozara Pantelic

This technical note describes the transfer of continuous, single-layer, pristine graphene to standard Quantifoil TEM grids. We compare the transmission properties of pristine graphene substrates to those of graphene oxide and thin amorphous carbon substrat ...

Nanoparticules à noyau métallique recouvert de silice.

ÉL’invention concerne des nanoparticules à base d’un métal, d’un alliage ou d’un dérivé métallique revêtu d’une couche de silice dans lesquelles la silice est de la silice cristalline, en particulier de la silice cristalline sous forme de cristobalite. Elles peuvent être préparées à partir de nanoparticules à silice amorphe en faisant cristalliser celle-ci par un traitement thermique à l’air ou sous atmosphère inerte à une température comprise entre 900 et 1400°C, et être utilisées comme pigments pour céramiques ou dans le domaine biologique.

Preform to produce metallic foam

Andreas Mortensen

A process for producing a metal article containing at least 10% interconnected porosity, using a preform (11), comprising: mixing an organic binder, a wetting agent and a granular material, to obtain a mouldable paste that combines 10 vol. pct. or more of ...

Uniaxial deformation of microcellular metals: model systems and simplified analysis

Andreas Mortensen, Etienne Combaz, Sébastien Philippe Soubielle, Frédéric Diologent, Yves Conde, Randoald Müller, Jean-François Despois

Microcellular aluminium can be produced by a process known as replication; this involves the infiltration of a packed bed of NaCl particles which are subsequently leached after metal solidification. The resulting material features a uniform distribution of ...

Micro-, meso- and macrostructures in replicated microcellular aluminium

Yves Conde

This thesis is focused on the properties of microcellular aluminium, produced by replication processing, at the micro, meso and macrostructural level. The replication process is based on the infiltration of a porous sodium chloride (NaCl) perform with molt ...

Age-Hardening Response of Replicated Microcellular Al-4.5%Cu

Andreas Mortensen, Yves Conde

We study the response to age hardening of Al-4.5%Cu replicated foams with 75 and 400 pm cell sizes and with varying relative densities. The 400 mu m cell size foams have a similar behavior to the bulk alloy, whereas the 75 pm cell size foams with relative ...
