Chemical shift extremum of 129Xe(aq) reveals details of hydrophobic solvation
Scientific Reports, 2018 The 129Xe chemical shift in an aqueous solution exhibits a non-monotonic temperature dependence, featuring a maximum at 311 K. This is in contrast to most liquids, where the monotonic decrease of the shift follows that of liquid density.

An application of nuclear magnetic resonance spectroscopy to study faecal canine metabolome
Italian Journal of Animal Science, 2021 Metabolomics provides a description of the phenotype of an organism and complementary biochemical information to genomics and proteomics. The purpose of this research was to depict the metabolite profile of faecal samples from dogs fed three different ...

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.

NMR evidence for static local nematicity and its cooperative interplay with low-energy magnetic fluctuations in FeSe under pressure [PDF]
, 2017 We present $^{77}$Se-NMR measurements on single-crystalline FeSe under pressures up to 2 GPa. Based on the observation of the splitting and broadening of the NMR spectrum due to structural twin domains, we discovered that static, local nematic ordering ...

Flow injection analysis NMR (FIA–NMR): a novel flow NMR technique that complements LC–NMR and direct injection NMR (DI–NMR) [PDF]
Magnetic Resonance in Chemistry, 2003 AbstractDetails of a new flow NMR technique, flow injection analysis NMR (FIA–NMR), are presented for the first time. This method blends some aspects of both liquid chromatography–NMR and direct injection NMR, and complements both. FIA‐NMR is shown to be useful as an analytical technique, especially for repetitive analyses, and may also prove useful in

A new structural arrangement in proteins involving lysine NH3 + group and carbonyl
Scientific Reports, 2017 Screening of the Protein Data Bank led to identification of a recurring structural motif where lysine NH3 + group interacts with backbone carbonyl. This interaction is characterized by linear atom arrangement, with carbonyl O atom positioned on the three-
