NMR relaxation rate in non-centrosymmetric superconductors [PDF]
Physical Review B, 2005 The spin-lattice relaxation rate of nuclear magnetic resonance in a clean superconductor without inversion center is calculated for arbitrary pairing symmetry and band structure, in the presence of strong spin-orbit coupling.Comment: 4 ...

NORD: NO Relaxation Delay NMR Spectroscopy [PDF]
Angewandte Chemie International Edition, 2021 AbstractThe novel concept of NORD (NO relaxation delay) NMR spectroscopy is introduced. The idea is to design concatenated experiments in a way that the magnetization used in the first relaxes toward equilibrium during the second and vice versa, thus saving instrument time.

Exploring catalyst passivation with NMR relaxation [PDF]
Faraday Discussions, 2017 NMR relaxation has recently emerged as a novel and non-invasive tool for probing the surface dynamics of adsorbate molecules within liquid-saturated mesoporous catalysts. The elucidation of such dynamics is of particular relevance to the study and development of solvated green catalytic processes, such as the production of chemicals and fuels from bio ...

Understanding NMR relaxometry of partially water-saturated rocks [PDF]
Hydrology and Earth System Sciences, 2015 Nuclear magnetic resonance (NMR) relaxometry measurements are commonly used to characterize the storage and transport properties of water-saturated rocks. Estimations of these properties are based on the direct link of the initial NMR signal amplitude to

Numerical study of NMR relaxation responses in synthetic clayey sandstone by dual-scale modeling [PDF]
E3S Web of Conferences, 2023 Nuclear Magnetic Resonance (NMR) relaxometry is a common technique for petrophysical characterization of sedimentary rocks. The standard interpretation of NMR relaxation response assumes that the fast diffusion limit is valid for the whole pore space ...

Theoretical study of NMR relaxation due to rattling phonons [PDF]
, 2007 We calculate the NMR relaxation rate due to quadrupolar coupling of the nucleus to a local, strongly anharmonic phonon mode. As a model potential for a rattling motion we consider a square-well potential.

Fast-field-cycling ultralow-field nuclear magnetic relaxation dispersion
Nature Communications, 2021 Nuclear spin polarization and relaxation can be studied using nuclear magnetic resonance (NMR). Here the authors demonstrate a combination of fast-field cycling and optical magnetometry techniques, to realize a NMR sensor that operates in the region of ...

125Te spin-lattice relaxation in a candidate to Weyl semimetals WTe2
Results in Physics, 2021 The tungsten ditelluride WTe2 was suggested to belong to the Weyl semimetal family. We studied 125Te spin-lattice relaxation and NMR spectra in a WTe2 single crystal within a large range from 28 K up to room temperature.
