Light switch: Autumn leaves

Date: Dec 1, 2016

Author: David Bradley

Yellow chlorophyll decomposition products are environment-responsive chiral photoswitches researchers in Austria have found using UV-Vis and nuclear magnetic resonance (NMR) spectroscopy, and X-ray crystallography studies.

Graphene plasmons: So NIR

Date: Dec 1, 2016

Author: David Bradley

Efficient absorption enhancement at a wavelength of 2 micrometres by graphene has been demonstrated with the plasmons of nanoscale graphene discs by researchers in Denmark.

Poverty and the growing brain: MRI clues

Date: Dec 1, 2016

Author: David Bradley

Poverty can have a seriously detrimental effect on the childhood development of the brain. However, a magnetic resonance imaging (MRI) study of children of families participating in the Strong African American Families Program has shown for the first time that this effect can be countered by supportive parenting and family relationships.

Double salt: Negative platinum X-rayed

Date: Dec 1, 2016

Author: David Bradley

The first intermetallic double salt containing the noble metal, platinum, has been synthesised by researchers at the US Department of Energy's Ames Laboratory in Ames, Iowa. The team used X-ray studies to verify their method.

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.

Vendor column: If you aren’t controlling your process, your process is controlling you

Date: Nov 29, 2016

Author: Daniel Shiley

This is the fourth and final segment in the series on near-infrared for the mining industry. Development of quantitative data sets was discussed in the previous article. This article will discuss the finished quantitative model as it can be used to optimize mine productivity.

Journal Highlight: Can transcutaneous near infrared spectroscopy detect severe hepatic ischemia: a juvenile porcine model?

Date: Nov 28, 2016

Author: spectroscopyNOW

The suitability of near infrared spectroscopy for monitoring severe hepatic ischemia following pediatric liver transplantation has been studied using juvenile pigs, revealing severe limitations.

Journal Highlight: Allergic reactions in red tattoos: Raman spectroscopy for 'fingerprint' detection of chemical risk spectra in tattooed skin and culprit tattoo inks

Date: Nov 28, 2016

Author: spectroscopyNOW

Raman spectroscopy has been tested as a screening technique for chemical characterisation of tattoo pigments in pathologic reacting tattoos and tattoo ink stock products to depict unsafe pigments and metabolites.

Journal Highlight: Assessment of exposure to MRI motion-induced fields based on the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines

Date: Nov 21, 2016

Author: spectroscopyNOW

Numerical simulations have been used to assess exposure for workers moving through the stray stationary field of common MRI scanners, performed according to the recent ICNIRP guidelines which aim at avoiding annoying sensory effects.
