Nosing in on bad water: Geosmin detector

Date: Sep 15, 2015

Author: David Bradley

A bioelectronic nose that can detect the common contaminants of "off" water, namely geosmin and 2-methylisoborneol, has been developed to preclude the need for cumbersome gas chromatographic or mass spectrometric testing equipment.

Journal Highlight: Comparison of analytical techniques for analysis of archaeological bronze

Date: Aug 31, 2015

Author: spectroscopyNOW

A flat axe (arsenic bronze) and a sickle (tin bronze) were subjected to multilaboratory analysis using INAA, ED–XRF, PIXE, TRXRF, FAAS, ICP–AES, ICP–MS, SEM–EDS, LA–ICP–MS and PGAA and the results compared.

Interstellar cyanoacetylene: Cationic and cloudy

Date: Aug 15, 2015

Author: David Bradley

Researchers in China have used zero-kinetic energy photoelectron spectroscopy to determine the quantum energy levels of the cyanoacetylene cation with unprecedented detail, the work has fundamental merit in organic chemistry but might also improve our understanding of interstellar clouds and the atmosphere of Saturn's largest moon Titan where this ion is present in abundance.
