Hot and cold moves of cyanide and water
(04 Sep 2009)
Temperature determines which molecule rocks out
Scientists have long known that molecules dance about as the temperature rises, but now researchers know the exact steps that water takes with a certain molecule. Results with small, electrically charged cyanide ions and water molecules reveal that ...

New clues about a hydrogen fuel catalyst
(07 Aug 2009)
To use hydrogen as a clean energy source, some engineers want to pack hydrogen into a larger molecule, rather than compressing the gas into a tank. A gas flows easily out of a tank, but getting hydrogen out of a molecule requires a catalyst. Now, ...

Sophisticated monitoring array to address mystery of uranium plume
(19 Sep 2008)
Groundwater contamination remains significantly unchanged for 10 years
Scientists have puzzled for years about why uranium contamination in groundwater continues to exceed drinking water standards in an area located at the south end of the Hanford Site. The Department of Energy wants answers to why the uranium ...

Powder power - a simple, efficient route to hydrogen fuel
(25 Jun 2008)
Chemists in the US have developed a simple reaction to make ammonia borane - a powder more hydrogen-dense than even liquid hydrogen. Their one-pot synthesis of this promising hydrogen storage material is reported in the first issue of the new Royal ...

You can't teach old materials new tricks
(19 Feb 2008)
Decades-old challenge has researchers seeking new materials for radiation detection
A more sensitive, more selective and easily deployable radiation detection material is necessary to meet complex 21st century challenges. In the AAAS symposium "Radiation Detectors for Global Security: The Need for Science-Driven Discovery," ...

New sensor system improves detection of lead, heavy metals
(14 Feb 2008)
PNNL develops inexpensive portable detection system for rapid, accurate analysis of toxic metals
The Department of Energy's Pacific Northwest National Laboratory has developed a new rapid, portable and inexpensive detection system that identifies personal exposures to toxic lead and other dangerous heavy metals. The device can provide an ...

'Hot' oxygen atoms on titanium dioxide motivated by more than just temperature
(12 Feb 2008)
PNNL scientists find unexpected chemical behavior on catalyst surface
Like two ballroom dancers waltzing together, the two atoms of an oxygen molecule severed by a metal catalyst usually behave identically. But new research reveals that on a particular catalyst, split oxygen atoms act like a couple dancing the tango: ...
