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.

Explosive 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.

Journal Highlight: Water phytoremediation of cadmium and copper using Azolla filiculoides Lam. in a hydroponic system
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.

Magnetic 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.

Journal 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.

Journal 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.
