Bacterial insomnia: NMR finds dormancy inhibitors

Date: Dec 15, 2016

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy and other techniques have allowed an international team to reveal compounds that inhibit the bacterial ability to become dormant. Their work shows for the first time an oxygen-sensitive toxin-antitoxin system that might lead the way to new drugs to defeat bacterial resistance.

The spliceosome: NMR spFRET dice up protein complex

Date: Dec 1, 2016

Author: David Bradley

Prior to gene expression in the cell, the non-coding regions of the genome have to be removed by the spliceosome. A joint single pair Förster resonance energy transfer (spFRET) and nuclear magnetic resonance (NMR) spectroscopy study by researchers in Munich suggests that distinct conformations of a member of this molecular complex play a vital role in the process, with implications for biomedical science.

A salted battery: NMR by-products

Date: Nov 15, 2016

Author: David Bradley

Sodium-oxygen batteries have much improved cycle life due to highly concentrated electrolytes, according to US researchers who have used nuclear magnetic resonance (NMR) spectroscopy to identify the discharge byproducts.

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.
