Journal Highlight: Investigating effects of sample pretreatment on protein stability using SEC and high-resolution continuum source AAS

Date: Oct 6, 2014

Author: spectroscopyNOW

Size-exclusion chromatography and high-resolution atomic absorption spectrometry methods have been developed and evaluated to test the stability of proteins during different storage conditions and also the effects of adsorption before and during chromatography.

Antineutrino: Nuclear proliferation proxy

Date: Aug 15, 2014

Author: David Bradley

US scientists are looking to one of the tiniest of subatomic particles, the antineutrino, to determine whether this seemingly nondescript entity might reveal clues about illicit nuclear activity in political hotspots around the globe.

On the dot: Quantum reproducibility

Date: Jul 15, 2014

Author: David Bradley

An international collaboration has developed a technique for creating quantum dots with identical, deterministic sizes as revealed by scanning tunnelling microscopy. The research could allow quantum dot architectures to be constructed with complete control allowing technologists to develop new nanophotonics and quantum information processing systems as well as enabling various fundamental scientific studies.

Journal Highlight: Analysis of trace metals and perfluorinated compounds in 43 representative tea products from South China

Date: Jun 30, 2014

Author: spectroscopyNOW

Six trace metals (Cd, Pb, Cr, Cu, Zn, and Mn) were analyzed in 43 representative tea products (18 green, 12 Oolong, and 13 black teas) from 7 main tea production provinces in China, using atomic absorption spectrophotometer, while two perfluorinated compounds were measured by HPLC-MS/MS.

I like coffee: I like teeth

Date: Jun 15, 2014

Author: David Bradley

Atomic absorption spectroscopy has been used in a new study to analyse changing concentrations of calcium in tooth enamel as it responds to the antibacterial effects of strong coffee on oral microbes. The research suggests that while coffee may well be the downfall of those who wish to have a shiny, white smile, it could at least prevent coffee drinkers from losing their stained teeth.

Journal Highlight: Metals and electrolytes in sclerotic hippocampi in patients with drug-resistant mesial temporal lobe epilepsy

Date: Jun 2, 2014

Author: spectroscopyNOW

The hippocampi of patients with drug-resistant mesial temporal lobe epilepsy and hippocampal sclerosis who underwent anterior temporal lobe resection and amygdalohippocampectomy were analysed using ICP-OES.

Maximal magnetism: Single-atom limit

Date: May 15, 2014

Author: David Bradley

Scientists have shown for the first time the maximum theoretical limit on the energy required to control the magnetization of a single atom. The fundamental work could have implications for the future of research into magnetism and devices that utilize the phenomenon in technology.
