Exploring catalyst passivation with NMR relaxation [PDF]

open access: yesFaraday 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 ...

Digitally Based Precision Time-Domain Spectrometer for NMR Relaxation and NMR Cryoporometry

open access: yesMicro, 2023
NMR Relaxation (NMRR) is an extremely useful quantitative technique for material science, particularly for studying polymers and porous materials. NMR Cryoporometry (NMRC) is a powerful technique for the measurement of pore-size distributions and total ...

Numerical study of NMR relaxation responses in synthetic clayey sandstone by dual-scale modeling [PDF]

open access: yesE3S 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 ...

Understanding NMR relaxometry of partially water-saturated rocks [PDF]

open access: yesHydrology 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
