A review of the use of simple time-domain NMR/MRI for material-science
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 ...

Scleroglucan and guar gum: The synergistic effects of a new polysaccharide system
Scleroglucan (Sclg) and Guar Gum (GG) are both capable to give gels in the presence of borax and this study is focused on how a mixed system of the two polysaccharides can be affected by the addition of borax. The anisotropic swelling behavior of tablets

Determination of herb authenticity by low-field NMR
The safe use of herbal medicines requires prior authentication of the raw materials used to make them. This is an important step, since the ingestion of herbal preparations or extracts can cause serious health problems. Among the different analytical techniques, nuclear magnetic resonance (NMR) spectroscopy has the advantage of being non-invasive and ...

Selective drug trace detection with low-field NMR [PDF]
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

Low‐field
AbstractOil is a prominent, but multifaceted material class with a wide variety of applications. Technical oils, crude oils as well as edibles are main subclasses. In this review, the question is addressed how low‐field NMR can contribute in oil characterization as an analytical tool, mainly with respect to quality control.
