Droning on and off: Infrared mine detection
Date: Jul 1, 2018
Author: David Bradley
Cost effective and time efficient remote sensing that uses a "drone" equipped with an infrared camera can detect plastic munitions and explosives of concern such as so-called "butterfly" mines has enormous potential for clearing up lethal objects left behind after a military conflict.

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: 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.

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.
