Pillars of Creation: Clues to life

Date: May 1, 2018

Author: David Bradley

Scientists have mimicked the extreme conditions of deep space - cryogenic temperatures, ultrahigh vacuum, lots of ice particles covered with methane, ammonia, and carbon dioxide - and then blasted this miniature universe with low energy electrons, which are abundant in space, to see if they can generate the molecules of life, the amino acids. They used various techniques to pluck out information about of the products and suggest that Fourier transform infrared (FTIR) spectroscopy might be used to obtain...

Journal Highlight: Hydrocerussite‐related minerals and materials: structural principles, chemical variations and infrared spectroscopy

Date: Apr 30, 2018

Author: spectroscopyNOW

The general structural principles, chemical variations and IR spectra of the rapidly growing family of hydrocerussite‐related minerals and synthetic materials have been reviewed and the crystal structures of hydrocerussite from Merehead quarry, Somerset, England, and of its synthetic analogue, have been reported here for the first time.

Journal Highlight: The influence of bound water on the FTIR characteristics of starch and starch nanocrystals obtained from selected natural sources

Date: Apr 3, 2018

Author: spectroscopyNOW

Starch nanocrystals produced from natural sources like rice, ragi, wheat and sorghum have been compared by FTIR, DSC and TGA, showing that more bound water interacts with starch compared to starch nanocrystals.

Flickering light: Electrical impulse

Date: Apr 1, 2018

Author: David Bradley

A material that generates an electrical impulse when sunlight flickers over it has been developed by researchers at the Laboratory of Organic Electronics at Linköping University, Sweden, the work extends an infrared materials previously developed by the team.

Journal Highlight: ATR-FTIR spectroscopy and μ-EDXRF spectrometry monitoring of enamel erosion caused by medicaments used in the treatment of respiratory diseases

Date: Mar 5, 2018

Author: spectroscopyNOW

The erosive capacities of the four most commonly prescribed respiratory disease syrup medicaments on enamel have been estimated using micro-energy-dispersive X-ray fluorescence spectrometry and attenuated total reflection Fourier transform infrared spectroscopy.

RNA world: IR reveals watery shell

Date: Feb 5, 2018

Author: David Bradley

Two-dimensional infrared spectroscopy allows the time evolution of vibrational excitations to be mapped in the interaction of RNA with water molecules to reveal how water molecules at the nucleic acid's surface undergo tipping motions or librations.

Journal Highlight: Feasibility of near infrared transmittance spectroscopy to predict fatty acid composition of commercial processed meat

Date: Feb 1, 2018

Author: spectroscopyNOW

Near infrared transmittance spectroscopy can be considered as a reliable method for predicting the main groups of fatty acids in processed meat products, whereas predictions of individual fatty acid are less reliable.

Methane methods: IR reveals catalytic details

Date: Jan 8, 2018

Author: David Bradley

Infrared spectroscopy techniques and a quantum theory model have been used by an international team to investigate the nature of methane dissociation reactions on platinum. The results could offer a route map to novel catalysts for converting natural gas into higher chemicals.

Journal Highlight: A functional near-Infrared spectroscopy study of trauma-related auditory and olfactory cues: Posttraumatic stress disorder or combat experience?

Date: Jan 1, 2018

Author: spectroscopyNOW

A combat-related PTSD symptom provocation paradigm using functional near-infrared spectroscopy has been used to elicit unique neurological responses across three groups: combat veterans with PTSD, combat veterans without PTSD, and nonmilitary participants without PTSD.
