Incommunicado and in pain: IR to the rescue

Date: Nov 1, 2017

Author: David Bradley

Functional near-infrared spectroscopy (fNIRS) could offer hope to non-verbal patients who are suffering from pain allowing their carers and clinicians to observe episodes of pain even when the patient cannot communicate the problem.

Journal Highlight: Quantification of cocaine in ternary mixtures using partial least squares regression applied to Raman and Fourier transform infrared spectroscopy

Date: Oct 2, 2017

Author: spectroscopyNOW

FTIR and Raman spectroscopy have been used to to identify and quantify substances found at the locations of suicide attempts, poisonings, and drug consumption sites, including crack samples containing a cocaine base and adulterants commonly seized in drug busts, such as caffeine, lidocaine, and sodium carbonate.

Journal Highlight: Carbon–sulfur chains: A high-resolution infrared and quantum-chemical study of C3S and SC7S

Date: Sep 4, 2017

Author: spectroscopyNOW

C3S and SC7S, produced by laser ablation of carbon-sulfur targets, have been characterised by IR spectroscopy and quantum mechanical calculations, leading to the first gas-phase spectroscopic detection of the long SC7S cumulenic chain.

Core of the problem: Cometary IR

Date: Aug 1, 2017

Author: David Bradley

NASA's Wide-field Infrared Survey Explorer (WISE) spacecraft has delivered new insights into the properties of long-period comets. In work led by James Bauer of the University of Maryland it has been shown that there are seven times as many long-period comets at least 1 kilometre in diameter than previously predicted.

Journal Highlight: Challenges in model development for meat composition using multipoint NIR spectroscopy from at-line to in-line monitoring

Date: Jul 31, 2017

Author: spectroscopyNOW

Multipoint near-infrared spectroscopy has been used to predict the fat and moisture content of minced beef samples in at-line and on-line modes and the obstacles encountered during in-line monitoring have been identified.

Journal Highlight: Glycan fingerprinting via cold-ion infrared spectroscopy

Date: Jul 3, 2017

Author: spectroscopyNOW

Cold-ion IR spectroscopy of oligosaccharide ions reveals many well-resolved absorption features that are diagnostic for minute structural variations, making it a key technology combined with mass spectrometry to unravel complex glycomes.

Combing the atmosphere: IR gas signatures

Date: Jul 1, 2017

Author: David Bradley

An infrared laser that can comb the air between it and a quadcopter flying perhaps several kilomnetres away can reveal precisely what gases are in the atmosphere over a city or other region, according to NIST scientists.
