Painting with gumtion: Accelerating art

Date: Jan 15, 2017

Author: David Bradley

J.W.M. Turner used gumtion to make his paintings dynamic. It wasn't simply that he was a dab hand with the brush, he literally used a mixture called gumtion comprising mastic resin with a lead acetate additive to make his oils flow more slicker and smoother across the canvas a spectroscopic study shows.

Sweet substitution: NMR and insulin analogue

Date: Jan 6, 2017

Author: David Bradley

Replacing a particular hydrogen with an iodine atom to create a halogenated insulin analogue maintains the functionality of the glucose-control hormone but makes it act much faster. Nuclear magnetic resonance spectroscopy and X-ray crystallography have been used to investigate the structure.

Journal Highlight: 14N Solid-state NMR spectroscopy of amino acids

Date: Jan 1, 2017

Author: spectroscopyNOW

14N Ultra-wideline solid-state NMR spectra were obtained for 16 naturally occurring amino acids and four related derivatives by using the WURST–CPMG pulse sequence and frequency-stepped techniques.

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.
