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.
The molecular dynamics of a series of organometallic complexes covalently bound to amorphous silica surfaces is determined experimentally using solid-state nuclear magnetic resonance (NMR) spectroscopy and density functional theory calculations (DFT). The ...
An important development in the field of NMR spectroscopy has been the advent of hyperpolarization approaches, capable of yielding nuclear spin states whose value exceeds by orders-of-magnitude what even the highest-field spectrometers can afford under Bol ...
Pulsed Field Gradients (PFGs) have become ubiquitous tools not only for Magnetic Resonance Imaging (MRI), but also for NMR experiments designed to study translational diffusion, for spatial encoding in ultra-fast spectroscopy, for the selection of desirabl ...
Coherence transfer from ‘spy nuclei’ such as 1H or 13C (S = 1/2) was used to excite single- or double-quantum coherences of 14N nuclei (I = 1) while the S spins were aligned along the static field, in the manner of heteronuclear single-quantum correlation ...
We observed and characterized two distinct signals originating from different pools of water protons in solid-state NMR protein samples, namely from crystal water which exchanges polarization with the protein (on the NMR timescale) and is located in the pr ...
PARIS recoupling irradiation, despite a tow rf amplitude, can promote efficient magnetization transfer during solid-state NMR experiments at 900 MHz over a wide range of differences in isotropic chemical shifts in microcrystalline proteins. ...
Reliable quantification of the macromolecule signals in short echo-time H-1 MRS spectra is particularly important at high magnetic fields for an accurate quantification of metabolite concentrations (the neurochemical profile) due to effectively increased s ...
The solid-state NMR H-1 homonuclear decoupling sequences in the DUMBO family are shown to be effective at ultra-fast MAS rates of up to 65 kHz. The sequences are applied to model compounds glycine and [2-C-13]-L-alanine as well as the dipeptide beta-L-Asp- ...
The advantages offered by ultra-fast (>60 kHz) magic angle spinning (MAS) rotation for the Study of biological samples, notably containing paramagnetic centers are explored. It is shown that optimal conditions for performing solid-state C-13 NMR under 60 k ...
The composition and evolution of a brushite-type calcium phosphate cement was investigated by Solid-State NMR and X-ray during the setting process. The cement is obtained by mixing beta-tricalcium phosphate [Ca-3(PO4)(2), beta-TCP] and monocalcium phosphat ...
