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.
C59N magnetic fullerenes were formed inside single-wall carbon nanotubes by vacuum annealing functionalized C59N molecules encapsulated inside the tubes. A hindered, anisotropic rotation of C59N was deduced from the temperature dependence of the electron s ...
During the last two decades, magnetic resonance imaging (MRI) has evolved into one of the most powerful techniques in medical diagnosis. Among the various medical diagnostic modalities, such as X-ray or ultra-sound imaging, MRI is the technique of choice e ...
The increasing use of contrast agents in magnetic resonance imaging (MRI) for medical diagnosis is due to the ability, called relaxivity, of these paramagnetic compounds to accelerate the relaxation of the surrounding water proton spins. A new classical fo ...
A novel single-shot spectral editing technique for in vivo proton NMR is proposed to recover resonances of low-concentration metabolites obscured by very strong resonances. With this new method, editing is performed by transferring transverse magnetization ...
An ultrashort-echo-time stimulated echo-acquisition mode (STEAM) pulse sequence with interleaved outer volume suppression and VAPOR (variable power and optimized relaxation delays) water suppression was redesigned and optimized for human applications at 4 ...
Images directly visualizing the spatial spin-diffusion process are reported. The measurements were performed using a magnetic resonance force microscope. The field gradient associated with the forcedetection experiment is large enough to affect the spin dy ...
Magnetic resonance spectroscopy imaging (MRSI) is a promising and developing tool in medical imaging. Because of various difficulties imposed by the imperfections of the scanner and the reconstruction algorithms, its applicability in clinical practice is r ...
Nuclear magnetic resonance (NMR) signals with short T1 and T2, such as the 13C signal of glycogen, are difficult to localize in three dimensions without major signal loss. A pulse sequence that accomplishes the spatial localization of 1H-decoupled 13C NMR ...
Possibilities of NMR technique will be illustrated by a selection of high-field NMR results on antiferromagnetic quantum spin systems, obtained at the Grenoble High Magnetic Field Laboratory. We present results for two well known systems, doped Haldane spi ...
A pulsed field gradient NMR (= nuclear magnetic resonance) method using stimulated echoes for determining the translational isotropic or anisotropic diffusion coefficient of a molecule or supramolecular assembly or the flow rate and direction of fluids con ...
