Journal Highlight: Analysis of Late Bronze Age glass axes from Nippur - a new cobalt colourant

Date: Oct 1, 2012

Author: spectroscopyNOW

A multidisciplinary study of a unique group of Late Bronze Age ceremonial glass axe heads and other artefacts shows that these are the first significant group of glasses coloured with cobalt to be identified from the Near East.

Journal Highlight: Differential distribution of cobalt, chromium, and nickel between whole blood, plasma and urine in patients after metal-on-metal (MoM) hip arthroplasty

Date: Sep 3, 2012

Author: spectroscopyNOW

Cobalt, chromium and nickel were measured in the blood, plasma and urine of hip replacements patients by ICPMS to help understand the reasons for poor device outcome.

Heavy metal in pregnancy: Health risks

Date: Aug 15, 2012

Author: David Bradley

Atomic absorption spectroscopy has been used to measure levels of metals in blood plasma from expectant mothers as a proxy for oxidative stress. Increased levels of iron in pregnancy reveals an association with high blood pressure conditions including hypertension and pre-eclampsia, although causation is not demonstrated.

Journal Highlight: Metals in organic and conventional wheat flours determined by an optimised and validated ICP-MS method

Date: Aug 6, 2012

Author: spectroscopyNOW

A simple ICP-MS method was devised for multi-element determination in cereal products and to evaluate multi-element content differences in commercially available conventional vs. organic wheat flours.

Atom foreshadowed: Optical limits

Date: Jul 15, 2012

Author: David Bradley

Australian researchers have carried out the first absorption imaging of a single atom isolated in a vacuum and clearly reveal a visible shadow cast by the atom.

Journal Highlight: The variation of mineral profiles from grape juice to monovarietal Cabernet Sauvignon wine in the vinification process

Date: Jul 2, 2012

Author: spectroscopyNOW

The variation of the profiles of 10 minerals in the vinification process was investigated to lay the foundations for hazard analysis and critical control point (HACCP).

Helical light: Interference and tweezers

Date: Jun 15, 2012

Author: David Bradley

A scientist in the UK has demonstrated theoretically that "dark" helices formed by laser beams could be useful in lithography, chiral separations of molecules and optical tweezer applications.

Journal Highlight: Study on the provenance of Xicun Qingbai wares from the northern Song Dynasty of China

Date: Jun 4, 2012

Author: spectroscopyNOW

Qingbai porelain samples from the Xicun, Hutian (Jingdezhen) and Chaozhou (Guangdong Province) kilns were analysed by laser ablation inductively coupled plasma mass spectrometry and energy-dispersive X-ray fluorescence probe.

Journal Highlight: Plasma protein oxidation correlation in sickle-cell anemia patients

Date: May 15, 2012

Author: spectroscopyNOW

The oxidative medium of sickle-cell anemia was evaluated by protein oxidation parameters and their correlation with lipids and metal ions were investigated both in the plasma and in the erythrocyte.
