Combing the atmosphere: IR gas signatures

Date: Jul 1, 2017

Author: David Bradley

An infrared laser that can comb the air between it and a quadcopter flying perhaps several kilomnetres away can reveal precisely what gases are in the atmosphere over a city or other region, according to NIST scientists.

Bacterial power: Polymer boost for fuel cell

Date: Jul 1, 2017

Author: David Bradley

By coating individual bacterial cells with an electron-conducting polymer, polypyrrole, researchers in Singapore were able to build a high-performance anode for microbial fuel-cell applications. They used UV-Vis spectroscopy and other techniques to monitor their progress and test their device.

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.

Closed model: NMR and X-rays open up enzyme clue

Date: Jul 1, 2017

Author: David Bradley

A structural model of the closed state of the "energy budget" enzyme adenylate kinase emerges from a nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography study by European scientists.
