A review of the use of simple time-domain NMR/MRI for material-science
SN Applied Sciences, 2021 The intention of this discussion is as a simple introduction for general—non-nuclear magnetic resonance (NMR)-specialist—materials scientists, to make them aware as to how some of the materials science measurements that they need to make might possibly ...

Functional group resolved NMR relaxation of 3-carbon adsorbates in mesoporous alumina
Magnetic Resonance Letters, 2023 NMR relaxation analysis provides a unique and non-invasive probe of fluid dynamics within porous materials, and may be applied to the interpretation of a wide variety of material and interfacial characteristics.

Selective drug trace detection with low-field NMR [PDF]
The Analyst, 2011 Advances with para-hydrogen induced polarization open up new fields of applications for portable low-field NMR. Here we report the possibility of tracing drugs down to the micromolar regime. We could selectively polarize nicotine quantities similar to those found in one cigarette. Also less than 1 mg of harmine, a drug used for treatment of Parkinson's

Solid-state NMR signals at zero-to-ultra-low-field
Journal of Magnetic Resonance Open, 2022 Zero-to-ultra-low-field nuclear magnetic resonance (ZULF NMR) is fast emerging as a viable spectroscopic approach to study samples under conditions dominated by internal spin interactions.

Digital filters for low‐field NMR
Concepts in Magnetic Resonance Part B: Magnetic Resonance Engineering, 2016 AbstractWe review the theory and operation of digital filters in modern nuclear magnetic resonance (NMR) spectrometers with fully digital receivers. Custom digital filters tailored for particular experimental requirements offer substantial improvements in signal‐to‐noise ratio (SNR), sensitivity, pulse sequence timing, and rejection of heteronuclear ...

Guar gum/borax hydrogel: Rheological, low field NMR and release characterizations
eXPRESS Polymer Letters, 2013 Guar gum (GG) and Guar gum/borax (GGb) hydrogels are studied by means of rheology, Low Field Nuclear Magnetic Resonance (LF NMR) and model drug release tests. These three approaches are used to estimate the mesh size (ζ) of the polymeric network.

Inline NMR via a Dedicated V-Shaped Sensor
Sensors, 2023 Process monitoring and control require dedicated and reliable measures which reflect the status of the process under investigation. Although nuclear magnetic resonance is known to be a versatile analytical technique, it is only seldomly found in process ...
