Detection of Explosives by Electronic Noses.

Bomb-sniffing dogs have become a required presence in airports and other public
arenas. Jehuda Yinon of the National Center for Forensic Science at the University
of Central Florida describes a potentially better approach: analytical devices
that sense vapors emitted by explosives and chemical weapons. These electronic
noses are smaller and less expensive than trained canines, allowing law enforcement
and security agencies to deploy the detectors at a wider range of potential terrorist
targets.

Analytical
Chemistry in the Developing World.
(281 KB PDF)
In too many developing countries, funding limits access to journals and the Internet,
let alone lab equipment and supplies. Analytical chemistry researchers Theodros
Solomon at the Addis Ababa University (Ethiopia), Malin Ákerblom at Uppsala
University (Sweden), and Erik W. Thulstrup at Roskilde University (Denmark) show
how individual scientists and various organizations have brought analytical chemistry
to the far corners of the globe.

Seeking
the Proteomic/Genomic Researcher.
(212 KB PDF)
As university-run proteomic and genomic centers proliferate across the country,
demand to fill those centers with people who know both biology and analytical
chemistry far exceeds the supply. Cheryl Harris speaks with researchers who advocate
broadening students' horizons as one solution. |
