Elusive effect: New IR detectors

Date: Jun 1, 2017

Author: David Bradley

The existence of a previously unobserved phenomenon related to particles known as Weyl fermions has been observed in Weyl semi-metals by an international high-energy physics team. The discovery could lead to a new type of infrared detector.

Journal Highlight: Quantitative IR microscopy and spectromics open the way to 3D digital pathology

Date: May 1, 2017

Author: spectroscopyNOW

The reconstruction of 3D quantitative chemical images of biological tissue by FTIR spectromicroscopy is reported, using an automated curve-fitting method to extract all of the intense absorption bands.

Emission control: Infrared metamaterial

Date: May 1, 2017

Author: David Bradley

A meta material that can be tuned to emit different wavelengths of infrared light in a controlled manner having absorbed energy could be used to make a device for collecting and so using waste heat.

Journal Highlight: The analysis of scalp irritation by coacervates produced in hair shampoo via FTIR with focal plane array detector, X-ray photoelectron microscopy and HaCaT cells

Date: Apr 3, 2017

Author: spectroscopyNOW

A coacervate that forms on the scalp from hair washing products has been characterised as a cationic polymer containing an anionic surfactant using FTIR-FPA and X-ray photoelectron microscopy.

Disease detector: Early signs visible to infrared

Date: Apr 1, 2017

Author: David Bradley

Fourier transform infrared (FTIR) spectroscopy can detect and characterize the release of sub-micrometre sized microvesicles and how they change in response during the body's immunological response to bacterial infection.

Living catalysis: Gold complex imaged with NIR in mice

Date: Mar 1, 2017

Author: David Bradley

The propargyl ester imaging probe Cy7.5-OProp was used as a near-infrared imaging probe for whole-body imaging to reveal how catalysis with a gold complex can be carried out in live mice, according to research published in the journal Angewandte Chemie.

Journal Highlight: Acidic weathering of basalt and basaltic glass: 1. Near-infrared spectra, thermal infrared spectra, and implications for Mars

Date: Feb 15, 2017

Author: spectroscopyNOW

The NIR and thermal IR spectra of lab-weathered crystalline and glassy basalts were consistent with spectral data from Mars, suggesting that glass-rich deposits and acidic weathering may have been widespread on the planet.

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.
