Three-faced star: Exoplanets in the infrared

Date: Feb 1, 2017

Author: David Bradley

The star HR 8799 has planets, hot planets far bigger than Jupiter and Saturn that swing around it in vast orbits. NASA's Spitzer Space Telescope first sighted the system with its vast circumstellar disc.Now, scientists have animated the observations to show us for the first time planets orbiting in and alien solar system.

Mossy synthesis: Sieboldine

Date: Jan 6, 2017

Author: David Bradley

A new, shorter total synthesis of a complex and intriguing compound, the Lycopodium alkaloid, (+)-sieboldine A, has been carried out by researchers in Japan. Infrared and nuclear magnetic resonance spectroscopy and high-resolution mass spectrometry, as well as optical rotation measurements validated the procedure.

Journal Highlight: Applicability of micro-FTIR in detecting shale heterogeneity

Date: Jan 1, 2017

Author: spectroscopyNOW

Samples of shale from the Illinois Basin have been analysed by micro-FTIR spectroscopy and scanning electron microscopic X-ray spectroscopy to explore the distribution, connectivity and chemical composition of organic matter, clay minerals, carbonate minerals and quartz.

Are metamaterials electric: Infrared imaging

Date: Nov 1, 2016

Author: David Bradley

A hybrid metamaterial behaves like an electric version of the chameleon's skin, changing colour when a current is applied but also becoming warmer, at least when viewed in the infrared. This could be the first proof-of-principle of a controllable metamaterial device, according to engineers at Penn State University.
