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.
Crack patterns of 53 nm and 103 nm thick silicon oxide coatings on poly(ethylene terephthalate) films are analyzed under equibiaxial stress loading, by means of a bulging cell mounted under an optical microscope with stepwise pressurization of film specime ...
We report on the first observation of both confined optical phonons and interface phonons in a single strained InAs quantum well grown on InP. Quasi resonant Raman measurements allow for the observation of interface modes. Informations about the mismatch i ...

Traction tests were performed on the bovine anterior cruciate ligament-bone complex at seven strain rates (0.1, 1, 5, 10, 20, 30, 40%/s). Corresponding stress-strain curves showed that, for a given strain level, the stress increased with the augmentation o ...
This paper reports and fully characterizes a coulometric nanotitrator and its application for four different types of titrations: precipitation, complex-formation, redox and acid-base nanotitrations. This simple device, composed of Pt or Ag planar electrod ...
By means of a Gleeble machine, the flow stress at steady-state creep in an AA3103 aluminium alloy has been measured for temperatures and strain rates relevant for thermally induced deformations in DC casting. The strain rate has been determined by measurin ...
High quality pseudomorphic Si1-yCy and Si1-x-yGexCy layers were grown on (100) Si between 530 and 650 degrees C by rapid thermal chemical vapor deposition in the SiH4/GeH4/SiH3CH3/H-2 system. These layers contained up to 30 at. % Ge and up to 2.2 at. % C. ...
Strain measurements on synthetic fibre rope constructions ofthe type used in marine applications are reported. The ropes are of a novel construction by virtue of incorporation of fibre-optic sensors for strain measurement. Two instrumentation approaches -a ...
