rssHeavy metals in your hibiscus: Infusion refusal
Date: May 15, 2013
Author: David Bradley
Inductively coupled plasma optical emission spectrometry (ICP-OES) and flame atomic absorption spectroscopy (FAAS) have been used to determine concentrations of metals in digests and infusions of Hibiscus sabdariffa (petals), Rosa canina (receptacles), Ginkgo biloba (leaves), Cymbopogon citratus (leaves), Aloe vera (leaves) and Panax ginseng (roots).

Acoustic archaeology: A sound approach
Date: May 15, 2013
Author: David Bradley
Researchers in the UK have carried out the most detailed analysis ever of the archaeological remains of the lost medieval town of Dunwich on England's Suffolk coast. The study analysed data obtained via acoustic spectroscopy to see the ruins through the murky depths of the North Sea.

Combined effort: Spectroscopic cancer clues under the microscope
Date: May 15, 2013
Author: David Bradley
A combination of atomic force microscopy (AFM) and nuclear magnetic resonance (NMR) spectroscopy could provide oncologists and cancer researchers with a new way to probe how cancer cells spread in the body through metastasis as well as other disease-related processes.

Journal Highlight: X-ray fluorescence analysis of Co, Ni, Pd, Ag, and Au in the scrapped printed-circuit-board ash
Date: May 7, 2013
Author: spectroscopyNOW
A validated method for the measurement of Co, Ni, Pd, Ag, and Au in ash derived from scrapped printed circuit boards used X-ray fluorescence spectrometry and gave similar results to those from atomic absorption spectrometry.

Journal Highlight: Determination of the anti-viral drug Ribavirin in dosage forms via micelle-enhanced spectrofluorimetric method
Date: May 7, 2013
Author: spectroscopyNOW
A simple and sensitive spectrofluorimetric method was developed for the determination of Ribavirin in pharmaceutical formulations, based on its fluorescence spectral behaviour in a sodium dodecyl sulfate micellar system.

Pork processing: Proteins influencing water holding capacity and drip loss
Date: May 1, 2013
Author: Steve Down
The proteome of fresh pork meat has been examined to locate proteins that are involved in the abnormal loss of water and soluble proteins due to limited water holding capacity, which impacts on meat quality.

Cocaine on currency: Higher levels associated with criminality
Date: May 1, 2013
Author: Steve Down
US scientists have analysed 17 years worth of data on the contamination of currency with cocaine to determine the levels which are statistically higher than background, so that banknotes contaminated by drug-related crime rather than general contamination during circulation can be identified.

Combined forces: AFM boosts IR
Date: May 1, 2013
Author: David Bradley
A technique that combines atomic force microscopy (AFM) with infrared spectroscopy has allowed researchers, for the first time, to study the infrared absorption of semiconductor plasmonic microparticles on the nanometre scale.
