Curious about Mars: Rover Raman

Date: Oct 1, 2017

Author: David Bradley

NASA's Curiosity rover has roamed the surface of Mars for the last five years with its ChemCam laser system capturing chemical data from its surroundings. Details of a Raman instrument that will be aboard the ChemCam on the NASA Mars 2020 rover, will be reported at the OSA Laser Congress, 1-5 October 2017 in Nagoya, Japan.

Journal Highlight: Applying portable Raman spectrometers for field discrimination of sulfates: Training for successful extraterrestrial detection

Date: Sep 4, 2017

Author: spectroscopyNOW

Portable miniature Raman spectrometers operating in the near-infrared (785 nm) and in the green (532 nm, currently selected for the ExoMars mission) were used on-site to estimate the mineralogical compositions of sulfate weathering crusts at Valachov (Bohemian Massif, Czech Republic).

Journal Highlight: Raman study of graphene nanoribbon analogs confined in single-walled carbon nanotubes and their high-pressure transformations

Date: Aug 10, 2017

Author: spectroscopyNOW

High-pressure transformation of single wall carbon nanotubes filled with perylene molecules that form short-chain nanoribbon analogs inside the tubes has been studied by Raman spectroscopy combined with theoretical simulation.

Journal Highlight: Nanodiamonds and silicate minerals in ordinary chondrites as determined by micro-Raman spectroscopy

Date: Jul 3, 2017

Author: spectroscopyNOW

Raman spectra of silicate and carbonaceous minerals in three ordinary chondrites have been measured to improve understanding of the impact process including peak metamorphic pressures present in carbon-bearing ordinary chondrites.

Crush a grape: Raman and FTIR seed phenols

Date: Jul 1, 2017

Author: David Bradley

The extraction of phenols from grape skin and seeds has been optimized by researchers at the University of Seville, Spain and Dublin Technology Institute, Ireland. They used Raman and attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopies to confirm the identities of the compounds remaining in the residue after processing.

Journal Highlight: Distinguishing individual DNA bases in a network by non-resonant tip-enhanced Raman scattering

Date: Jun 15, 2017

Author: spectroscopyNOW

Scanning tunneling microscope-controlled non-resonant TERS has been used to distinguish unambiguously between two individual complementary DNA bases (adenine and thymine) with a spatial resolution down to 0.9 nm.

Journal Highlight: Resonance Raman and UV-visible microscopy reveals that conditioning red blood cells with repeated doses of sodium dithionite increases haemoglobin oxygen uptake

Date: May 1, 2017

Author: spectroscopyNOW

Raman confocal microscopy and UV–vis microscopy showed that successive additions of sodium dithionite to suspensions of red blood cells increased the rate and the capacity to uptake oxygen.
