Journal Highlight: OSIRIS‐REx visible and near‐infrared observations of the moon

Date: Jul 2, 2019

Author: spectroscopyNOW

Lunar spectra obtained by the OSIRIS‐REx Visible and InfraRed Spectrometer showed evidence of several candidate absorption features that confirmed results from other missions and provided evidence for lunar regolith containing a mixture of plagioclase and orthopyroxene minerals, as expected for highlands terrain.

Waxing lyrical: FTIR for plastic biodegradation

Date: Jul 1, 2019

Author: David Bradley

A range of techniques including Fourier-transform infradred (FTIR) spectroscopy have been used to study how gut bacteria in the Wax Moth, Galleria mellonella, can lead to bidegradation of that troubling plastic, polyethylene.

Prehistoric recycling: Sharpening shown by FTIR

Date: Jun 1, 2019

Author: David Bradley

Fourier-transform infrared (FTIR) spectroscopy reveals that our ancestors recycled and re-sharpened flint tools as long ago as 400 000 years, according to a study of artefacts from the Qesem Cave, located just outside Tel Aviv, Israel.

Saturn's storms: Infrared dives deep

Date: May 1, 2019

Author: David Bradley

Vast storms in the upper atmosphere of gas giant planets can contain material swept up from much lower in the atmosphere. Infrared data from the visible and infrared mapping spectrometer instrument aboard the Cassini spacecraft, which orbited and was used by astronomers to study the planet Saturn for thirteen years, reveals as much through deep-learning studies.

Journal Highlight: Development and application of Fourier transform infrared spectroscopy for detection of milk adulteration in practice

Date: Apr 29, 2019

Author: spectroscopyNOW

The simultaneous use of targeted and untargeted models applied to FTIR spectra for detecting specific milk adulterants across relevant concentration ranges has been reviewed and proven to be an effective strategy.

Journal Highlight: Monitoring cellular C:N ratio in phytoplankton by means of FTIR‐spectroscopy

Date: Apr 2, 2019

Author: spectroscopyNOW

Six phytoplankton species from different phylogenetic groups have been analyzed by FTIR spectroscopy to determine the effect of nutrient limitation on C:N quota patterns and develop a reliable multi‐species C:N prediction model based on a PLSR algorithm.

Tiny optics: Infrared refraction

Date: Apr 1, 2019

Author: David Bradley

Tiny optical elements - a meta lens - constructed from metal nanoparticles and a polymer could replace traditional refractive lenses for future imaging systems and optoelectronic devices. The meta lenses could be tuned from the near-infrared to the ultraviolet.

Journal Highlight: Updates of HITRAN spectroscopic database from 2008 to 2016 and implications for near‐infrared radiative transfer calculations

Date: Mar 6, 2019

Author: spectroscopyNOW

A line‐by‐line radiative transfer model has been used to investigate the impacts of updates of the HITRAN (High Resolution Transmission) database from 2008 to 2016 on clear‐sky calculations of absorption and solar heating rates in the near‐infrared region from 4000‐10000 cm‐1 (1.0‐2.5 μm).

Anticancer derivatives: FTIR gets to the core

Date: Mar 1, 2019

Author: David Bradley

Fourier-transform infrared (FTIR) spectroscopy in the frequency range 4000-400 cm-1 has been used to discern the possible geometrical shapes of sulfonamide derivatives with a salicylamide core that might be linked to unique activity of these molecules in cancer cells.
