Journal Highlight: Determination of nicotine, glycerol, propylene glycol and water in electronic cigarette fluids using quantitative 1H NMR

Date: Nov 1, 2016

Author: spectroscopyNOW

1H NMR alone has been used to identify and quantify the four most abundant components - propylene glycol, glycerol, water and nicotine - in e-cigarette liquids which can influence potential toxic and carcinogenic exposures.

Frankincense: NMR IDs cis and trans

Date: Nov 1, 2016

Author: David Bradley

You could usually predict the arrival of the Queen of Sheba for the unmistakable aroma of her scent - frankincense. Now, French scientists have used nuclear magnetic resonance (NMR) spectroscopy to identify the two main odour components of this centuries-old perfume and dubbed them (+)-cis- and (+)-trans-olibanic acids.

Negative union: NMR on ions together

Date: Oct 15, 2016

Author: David Bradley

Proton nuclear magnetic resonance (NMR) spectroscopy has been used in research that reveals the first definitive evidence for a new type of molecular structure with a bond between two negatively charged moieties.

Journal Highlight: Characterization of aging and solvent treatments of painted surfaces using single-sided NMR

Date: Oct 14, 2016

Author: spectroscopyNOW

Single-sided NMR confirms observed differences between two 17th century paintings with different treatment histories, and monitors the effect of different organic solvent application techniques on painted surfaces.

Journal Highlight: Prediction of beef color using time-domain nuclear magnetic resonance (TD-NMR) relaxometry data and multivariate analyses

Date: Oct 3, 2016

Author: spectroscopyNOW

Time-domain NMR and chemometrics were used to predict color parameters, such as lightness, redness and yellowness of beef in bulk samples and through packages.

Plutonium: NMR examines electrons

Date: Oct 1, 2016

Author: David Bradley

When it comes to plutonium, things are complicated. The radioactive element comes with a lot of technical and regulatory baggage. Now, a team at the Pacific Northwest National Laboratory and Washington State University have used fluorine-19 nuclear magnetic resonance (NMR) spectroscopy to take a close look at the element's inner electronic secrets when it finds itself in the superficially simple compound plutonium tetrafluoride.

Sclerostin inhibitors: NMR fighting osteoporosis

Date: Sep 15, 2016

Author: David Bradley

Drugs that are inhibitors of the protein sclerostin could be used to treat the debilitating bone-loss disease osteoporosis, according to researchers in Germany who used nuclear magnetic resonance (NMR) spectroscopy in thier investigations.

Journal Highlight: Molecular dynamics and composition of crude oil by low-field nuclear magnetic resonance

Date: Sep 5, 2016

Author: spectroscopyNOW

Low-field NMR relaxation measurements have been used to reveal the composition of crude oil, offering a low-cost method that can be used under poor working conditions in the field and in the wellbore.

HDL and heart disease: NMR and CT assessment

Date: Sep 1, 2016

Author: David Bradley

Data from nuclear magnetic resonance (NMR) spectroscopy and helical computerised tomography CT-scanning work together to assess the true role of high-density lipoprotein (HDL) in coronary heart disease.

Beta test: NMR TRIUMF

Date: Aug 15, 2016

Author: David Bradley

A depth-resolved ion-beam technique has been used by scientists in Canada to detect the nuclear magnetic resonance (NMR) signal from the near-surface region of an antiferromagnet material.
