Journal Highlight: Determination of internal temperatures within nitric oxide inductively coupled plasmas

Date: Jan 1, 2018

Author: spectroscopyNOW

A dual, in situ broadband absorption and optical emission spectroscopy system was designed to study neutral and excited state species energetics in nitric oxide plasmas, specifically rotational and vibrational temperatures across a broad spectral range.

Hot attraction: Atomic interferometry

Date: Dec 15, 2017

Author: David Bradley

 Hot bodies attract atoms, contrary to what physicists had assumed. The proof is in the atom interferometry data from researchers in the USA. Steven Chu of Stanford University and formerly the University of California Berkeley, Claude Cohen-Tannoudji, and William Phillips used optical tweezers to observe the minute effect.

Journal Highlight: Delicate changes of bioapatite mineral in pig femur with addition of dietary xylooligosaccharide: Evidences from Raman spectroscopy and ICP

Date: Nov 27, 2017

Author: spectroscopyNOW

Mineralogical changes of mineral bioapatite in pig femur in animals raised with various xylooligosaccharide additions at two stages of growth have been studied by Raman spectroscopy and ICP-OES.

Silicon solution: AAS testing in multiple sclerosis

Date: Nov 15, 2017

Author: David Bradley

Transversely -heated graphite furnace atomic absorption spectrometry has been used to show that drinking silicon-rich mineral water can increase the rate of urinary excretion of toxic aluminium ions in people with secondary progressive multiple sclerosis (SPMS).

Journal Highlight: A new procedure for determination of nickel in some fake jewelry and cosmetics samples after dispersive liquid–liquid microextraction by FAAS

Date: Oct 30, 2017

Author: spectroscopyNOW

A new, simple and cheap DLLME procedure that was optimized for the preconcentration of trace amounts of Ni(II) for its determination by FAAS has been applied to some fake jewelry and cosmetics samples.

Metals in meat: Bioavailability assessed by spectroscopy

Date: Oct 15, 2017

Author: David Bradley

Various techniques including graphite furnace atomic absorption spectrometry have been used to assess the bioavailability of metals ions present in beef, pork, and chicken after thermal treatment. The study shows that high temperatures make nutrient metal ions of calcium, copper, iron, magnesium and zinc less readily available.

Journal Highlight: Quantitative and qualitative analysis of three classes of sulfur compounds in crude oil

Date: Oct 2, 2017

Author: spectroscopyNOW

Three different classes of sulfur species present in crude oils have been quantified by LC separation and on-line detection and quantification by ICP-MS/MS, which will facilitate the optimization of desulfurization conditions during fuel production.
