Journal Highlight: State-of-the-art nanoplatform-integrated MALDI-MS impacting resolutions in urinary proteomics

Date: Jul 20, 2015

Author: spectroscopyNOW

This review comments on the challenges facing the conventional MALDI-MS technique and its upgrading by the introduction of nano-based techniques which can shift MALDI-MS from the lab to the bedside.

Poplar proteomics: Trees from distant sites compared

Date: Jul 15, 2015

Author: Steve Down

The proteome of poplar trees grown on grassland that had been irrigated for 40 years with starch wastewater from the potato industry reflected less abiotic stress than poplars grown in a forest, which suffered from phosphate ion deficiency.

Fracking chemicals: Organic screening

Date: Jul 15, 2015

Author: David Bradley

An organic screening framework has been used to identify organic components of hydraulic fracturing fluid that have potential groundwater risks associated with their use in the event of a spill. Of 659 different substances examined, researchers identified just 15 that could be problematic.

X-rayed catalyst: Bio-mimetic zeolite

Date: Jul 15, 2015

Author: David Bradley

Scientists in Germany and Netherlands have taken inspiration from nature to synthesise a novel zeolite catalyst that could be used to convert natural gas to liquid fuels. X-ray absorption spectroscopy and other techniques were key to their success.

Journal Highlight: Chemometrics-enhanced laser-induced thermal emission detection of PETN and other explosives on various substrates

Date: Jul 13, 2015

Author: spectroscopyNOW

Infrared emissions of pentaerythritol tetranitrate deposited as contamination residues on various substrates were measured to generate models for its detection and discrimination from the emissions of the substrates.
