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.
Crystal structure and dielectric properties of (1-x)Pb(Yb1/2Nb1/2)O-3-xPb(Sc1/2Nb1/2)O-3 (PYN1-xPSNx) (0less than or equal toxless than or equal to0.60) solid solution have been studied, and its pseudobinary phase diagram has been determined. The low-tempe ...
Using a density functional approach, we study structural and magnetic properties of small Fe-n clusters (nless than or equal to8) deposited on a MgO(100) substrate. Upon deposition, the clusters closely preserve their gas-phase structure. The magnetic mome ...
Magneto-optical Kerr effect, is used to investigate the magnetization of film made of uncoalesced cobalt and cobalt-platinum nanocrystals. For the pure cobalt nanocrystals, different film morphologies are obtained through application of magnetic field duri ...
A comparative characterization of crystal structure, morphology, sizes, and orientation in Ca phosphate precipitation from aqueous solutions, the mineral phase in bones, and mineral deposits on cardiac valves has been performed by high-resolution transmiss ...
An Eu NMR study in the ferromagnetic phase of pure and Gd-doped EuO was performed. A complete description of the NMR line shape of pure EuO allowed for the influence of doping EuO with Gd impurities to be highlighted. The presence of a temperature-dependen ...
We report neutron diffraction data on single crystal PrO2 which reveal a cooperative Jahn-Teller distortion at TD=120±2 K. Below this temperature an internal distortion of the oxygen sublattice causes the unit cell of the crystallographic structure to beco ...
Atomic clusters were identified in the ground state of the non-equilibrium Ta phase (Frank-Kasper sigma-structure type) at 15, 120 and 293K. The evolution of the clusters with temperature leads to two phase transformations at 65 and 150K which are related ...
We present an ab initio study of the magnetic surface reconstructions of the B2 FeV alloy using a self-consistent tight-binding linearized muffin tin orbital method developed in the atomic spheres approximation. For (001) and (111), the surface reconstruct ...
Incommensurate structure of Hexamethylenetetramine suberate (C6H12N4)(HOOC-(CH2)6-COOH) has been solved from single crystal x-ray diffraction data. A molecular dynamics simulation of this system was carried out from 15 K to 580K. A second-generation consis ...
We measured polycrystalline samples of SrRuO3 and both superconducting and nonsuperconducting (hydrogen loaded) ruthenocuprates-Eu1.5Ce0.5RuSr2Cu2O10-x (Ru-1222)-samples using ac susceptibility, Ru 3p x-ray photoemission and Ru 2p x-ray-absorption measurem ...
