Wild red wine: Microwave plasma-AES

Date: Nov 15, 2018

Author: David Bradley

The low-cost of microwave plasma-atomic emission spectrometry (MP-AES) outweighs its limitations and offers a simpler alternative technique for the quantitation of transition metals in food and drink samples.

Journal Highlight: Analysis of arsenic species in processed rice bran products using HPLC‐ICP‐MS

Date: Oct 1, 2018

Author: spectroscopyNOW

The contents of arsenic species (As(V), monomethylarsonic acid, As(III), and dimethylarsinic acid) in products such as bran powder and tablets have been compared using HPLC-ICP-MS and the risk of human exposure to inorganic arsenic has been assessed.

Curcumin against cancer: AAS tests metal

Date: Sep 15, 2018

Author: David Bradley

Atomic absorption spectrometry (AAS) has been used to determine platinum levels in A549 cancer cells and tumour tissues in experiments to test the efficacy of combining the natural product curcumin with the well-known anticancer drug cisplatin.

Journal Highlight: Chiral‐plasmon‐tuned potentials for atom trapping at the nanoscale

Date: Sep 3, 2018

Author: spectroscopyNOW

A novel chiral‐based tunable atom trapping system broadens the application of chiral metamaterials and has an important impact on all‐optical modulation, atomic on‐chip integration, manipulation of cold atoms, and quantum many‐body systems.

Advanced microscopy: Closing in on the liquid

Date: Aug 15, 2018

Author: David Bradley

 An international team has developed a new microscopy technique that allows them to visualize liquids at the nanoscale level - about 10 times greater resolution than possible with conventional transmission electron microscopy. The technique might greatly improve our understanding of the properties of liquids and liquid interfaces.

Journal Highlight: Advancing Mg/Ca analysis of coralline algae as a climate proxy by assessing LA‐ICP‐OES sampling and coupled Mg/Ca ‐ δ18O analysis

Date: Jul 30, 2018

Author: spectroscopyNOW

The use of LA‐ICP‐OES for Mg/Ca analysis of the climate proxy coralline alga Clathromorphum compactum has been validated and showed that climate archive verification is required for each unique coralline algal specimen.

Space nitrogen: Terahertz spectroscopy

Date: Jul 15, 2018

Author: David Bradley

Researchers in Austria have observed rotational transitions of the nonlinear triatomic molecular anion NH2- - the amide ion - using terahertz spectroscopy in a cryogenic radio frequency ion trap. The finding could point the way to detecting nitrogen-containing molecules in space.

Journal Highlight: Spectroscopic study of excited molecular nitrogen generation due to interactions of metastable noble gas atoms

Date: Jul 2, 2018

Author: spectroscopyNOW

The generation of excited nitrogen species by allowing noble gases to interact both with one another and ambient air has been examined.
