rssThe Mayan blues: Unravelling a mystery
Date: Apr 15, 2013
Author: David Bradley
A team of chemists in Spain has used kinetic analysis of cyclic voltammetry, infrared and ultraviolet spectroscopic data to re-affirm their 2006 hypothesis regarding how ancient artists got the Maya blues.

Panacea: Liquid grace or toxic snake oil?
Date: Apr 15, 2013
Author: David Bradley
Proton NMR spectroscopy and energy dispersive X-ray fluorescence (EDXRF) spectroscopy have been used to analyse snake oil, elixirs, panaceas and other quackery found in medicines prescribed from the 18th century onwards. It turns out that many of these often-patented nostrums contained highly dangerous levels of toxic elements including arsenic, mercury and lead, as well as cocaine, heroin and high levels of alcohol.

Journal Highlight: A tunable multicolour rainbow filter for improved stress and dislocation density field mapping in polycrystals using X-ray Laue microdiffraction
Date: Apr 8, 2013
Author: spectroscopyNOW
A new rainbow method for measuring the energy profiles of Laue spots while remaining in the white-beam mode proceeds in the opposite way compared to a monochromator-based method, by simultaneously removing several sharp energy bands from the incident beam.

Journal Highlight: NMR quadrupole liouvillians for arbitrary spin: Exact symbolic expressions and perturbation solutions
Date: Apr 1, 2013
Author: spectroscopyNOW
The NMR of quadrupolar nuclei with half-integer spins, which is described by treating the quadrupole interaction with second-order perturbation theory, has been elaborated on by calculating the transitions directly without the requirement of knowing the operators and wavefunctions.

Chocolate threats: Carcinogenic PAHs
Date: Apr 1, 2013
Author: Steve Down
Several polycyclic aromatic hydrocarbons have been determined in chocolate by GC/MS following a specially devised SPME procedure, giving a more sensitive method than an HPLC procedure developed in 2012 by the same research group.

Journal Highlight: Trace level detection and identification of nitro-based explosives by surface-enhanced Raman spectroscopy
Date: Apr 1, 2013
Author: spectroscopyNOW
Surface-enhanced Raman spectroscopy has been used to detect and identify traces of pentaerythritol tetranitrate (PETN), ethylene glycol dinitrate (EGDN), cyclotrimethylene-trinitramine (RDX) and trinitrotoluene (TNT) using commercially available substrates.

Journal Highlight: Analysis of audio magnetic tapes with sticky shed syndrome by ATR-FTIR
Date: Apr 1, 2013
Author: spectroscopyNOW
ATR-FTIR spectroscopy was used to identify spectroscopic markers for sticky shed syndrome in audio magnetic tapes with a poly(ester urethane) binder layer that are held in Library of Congress collections.
