Laser fluorescence: It's a gas
Date: Oct 15, 2013
Author: David Bradley
Using what they refer to as off-the-shelf, US researchers have developed a laser fluorescence spectroscopic technique to measure how and when nanocrystals adsorb and release hydrogen or other gases. The new investigative approach could be useful in research into lower-cost catalytic converters for vehicle exhausts, the future development of fuel cell technologies and improved gas sensors for industrial and anti-terrorism applications.

Date: Sep 30, 2013
Author: spectroscopyNOW
A pilot study assessing the use of LA–ICP–MS to analyse the clay matrix in pottery revealed the challenges of the technique for highly heterogeneous materials.
Read MoreExplosive laser: Shedding light on bombs
Date: Sep 15, 2013
Author: David Bradley
A laser that can detect microscopic traces of explosive chemicals on clothing and luggage has been developed by researchers at Michigan State University. The development opens up the possibility of the accurate identification of terror suspects are baggage that may represent a bomb threat at airports and other security checkpoints.

Date: Sep 2, 2013
Author: spectroscopyNOW
The utility of Azolla filiculoides growing in a hydroponic system for the phytoremediation of continental water polluted with cadmium and copper was evaluated, using FAAS to measure metal levels in the plant after 7 days of exposure.
Read MoreMagnetic switch: Terahertz controller
Date: Aug 15, 2013
Author: David Bradley
A terahertz laser developed at the Paul Scherrer Institute in Switzerland could be used to control the magnetization in a material on a timescale of just picoseconds. The extremely short pulses of electromagnetic radiation allow the magnetization to be changed with only a tiny delay opening up a new route to on-off switching in such materials for microelectronics and computing applications.
Read MoreJournal Highlight: The survival of gunshot residues in cremated bone: An inductively coupled plasma optical emission spectrometry study
Date: Aug 5, 2013
Author: spectroscopyNOW
ICP-OES analysis of gunshot residues in cremated bone is very sensitive and reliable and can be an appropriate nondestructive method for detecting residues on difficult and delicate substrates.
Read MoreLaser life: Astatine inspected
Date: Jul 15, 2013
Author: David Bradley
Laser spectroscopy has been used by scientists at CERN and Mainz to investigate the nature of the rare and artificially produced radioactive element astatine for the first time.
Read MoreJournal Highlight: Waste glass, vessels and window-panes from Thamusida (Morocco): Grouping natron-based blue-green and colourless Roman glasses
Date: Jul 2, 2013
Author: spectroscopyNOW
A collection of window-panes, vessels and alleged waste from Thamusida has been characterised by several techniques and compared with naturally coloured and colourless glasses of both Roman and later ages.
Read MoreConcentrate hard: Improving FAAS
Date: Jun 15, 2013
Author: David Bradley
A new preconcentration procedure for flame atomic absorption spectrometric (FAAS) determinations of heavy metals in food and water is both quick and simple to carry out.
Read MoreJournal Highlight: Ultra-trace silver determination in biological and water samples by EAAS after electrodeposition on a graphite probe
Date: Jun 3, 2013
Author: spectroscopyNOW
A rapid and simple procedure was developed for the selective and sensitive determination of ultra-trace silver in biological and environmental samples using the electrodeposition on a graphite probe modified with palladium followed by electrothermal atomic absorption spectrometry.
