Journal Highlight: Rapid discrimination of slimming capsules based on illegal additives by electronic nose and flash gas chromatography

Date: Mar 16, 2015

Author: spectroscopyNOW

Slimming capsule samples with illegally added substances were analyzed by electronic nose and flash GC and the data were analysed by PCA and LDA using a data fusion strategy to integrate the data into a single model.

Volatiles in flavourings: Restricted components measured by GC/MS

Date: Mar 15, 2015

Author: Steve Down

Scientists belonging to an international flavour organisation have developed a GC/MS method to measure several naturally occurring restricted substances such as thujone and camphor in flavourings and their raw materials.

Oily feedstock: NMR tests cosmetic raw materials

Date: Mar 15, 2015

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy has been used to test food industry waste, specifically waste material from fish and oilseed rape, which contains useful proteins and other substances that can be extracted for use in cosmetics and other non-food products that nevertheless require stringent quality and safety controls.

The FAAS track: Synbiotics and breast milk

Date: Mar 15, 2015

Author: David Bradley

FAAS (flame atomic absorption spectroscopy)  has been used to determine the concentration of essential trace metals, calcium, copper, iron, magnesium and zinc, in breast milk. The results  suggest that normal dietary intake do not affect levels available to breastfeeding infant and so mothers should be encouraged to take a supplement when they are deficient.

Dead red: Discoloured pigment X-rayed

Date: Mar 15, 2015

Author: David Bradley

"Red lead" is familiar as a component of the orange-red rustproof paint used on boats and other areas exposed to the sea and the weather. It has also been used by countless artists through the centuries. Unfortunately, the pigment undergoes discoloration over time. Now, researchers at DESY have used X-ray diffraction mapping and tomography experiments to help them explain the process.

Lending support to graphene: By design

Date: Mar 15, 2015

Author: David Bradley

Researchers have developed a set of criteria that could allow materials scientists to find suitable substrate materials for graphene in a targeted way. X-ray and photoelectron spectroscopic studies lend support.

Journal Highlight: Sequence-dependent dsDNA-templated formation of fluorescent copper nanoparticles

Date: Mar 9, 2015

Author: spectroscopyNOW

A facile method for sequence-dependent formation of fluorescent copper nanoparticles has been developed using dsDNA, AT sequences being better than random sequences.
