125Te spin-lattice relaxation in a candidate to Weyl semimetals WTe2

open access: yesResults 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.

NMR and MD studies of the temperature-dependent dynamics of RNA YNMG-tetraloops [PDF]

open access: yes, 2008
In a combined NMR/MD study, the temperature-dependent changes in the conformation of two members of the RNA YNMG-tetraloop motif (cUUCGg and uCACGg) have been investigated at temperatures of 298, 317 and 325 K. The two members have considerable different

Solid-state NMR spectroscopy on complex biomolecules [PDF]

open access: yes, 2010
Biomolecular applications of NMR spectroscopy are often merely associated with soluble molecules or magnetic resonance imaging. However, since the late 1970s, solid-state NMR (ssNMR) spectroscopy has demonstrated its ability to provide atomic-level ...

NMR logging activation sets selection and fluid relaxation characteristics analysis of tight gas reservoirs: A case study from the Sichuan Basin

open access: yesNatural Gas Industry B, 2018
With complex lithology and reservoir types, as well as high concealment and heterogeneity, tight reservoirs in the Sichuan Basin involve significant uncertainties in gas–water relationship.

Transverse NMR relaxation in biological tissues [PDF]

open access: yesNeuroImage, 2018
Transverse NMR relaxation is a fundamental physical phenomenon underpinning a wide range of MRI-based techniques, essential for non-invasive studies in biology, physiology and neuroscience, as well as in diagnostic imaging. Biophysically, transverse relaxation originates from a number of distinct scales - molecular (nanometers), cellular (micrometers),

Structural characterization of intrinsically disordered proteins by NMR spectroscopy. [PDF]

open access: yes, 2013
Recent advances in NMR methodology and techniques allow the structural investigation of biomolecules of increasing size with atomic resolution. NMR spectroscopy is especially well-suited for the study of intrinsically disordered proteins (IDPs) and ...

High-resolution NMR structure of an RNA model system : the 14-mer cUUCGg tetraloop hairpin RNA [PDF]

open access: yes, 2010
We present a high-resolution nuclear magnetic resonance (NMR) solution structure of a 14-mer RNA hairpin capped by cUUCGg tetraloop. This short and very stable RNA presents an important model system for the study of RNA structure and dynamics using NMR ...

How much entropy is contained in NMR relaxation parameters? [PDF]

open access: yes, 2021
Solution-state NMR relaxation experiments are the cornerstone to study internalprotein dynamics at atomic resolution on time scales that are faster than the overallrotational tumbling time,τR.

Proton NMR relaxometry as a useful tool to evaluate swelling processes in peat soils [PDF]

open access: yes, 2010
Dramatic physical and physico-chemical changes in soil properties may arise due to temperature and moisture variations as well as swelling of soil organic matter (SOM) under constant conditions.
