With the tags, military personnel will be able to stand in a warehouse full of tagged M16s, inventory up to 50 weapons a second and quickly know which weapons are being stored and which may be missing or in use.
Chemistry stops chromium contamination - Chromium contaminated soil - they're carting it up and carrying it away as part of cleanup projects at government and industrial sites throughout the United States. But researchers at Pacific Northwest have found a way to convert it to a less hazardous form that can be left in place.
By injecting diluted hydrogen sulfide into the subsurface, a chemical reaction converts highly toxic hexavalent chromium to trivalent chromium, which occurs naturally in soils.
This chemical reduction of chromium causes the material to cling to soil particles and not migrate down to the water table. Without conversion, the toxic form of chromium moves quickly through soil into groundwater and possibly into rivers, where it can harm juvenile fish.
Early demonstration of the technology shows potential for large cost savings. Additional tests are planned at a DOE site that has extensive chromium contamination.
Energy efficiency at 'core' of home - Home, sweet, energy-efficient home could be the sign hanging inside a manufactured home built with foam core panels designed to reduce heating and cooling costs by as much as half. This summer, Pacific Northwest researchers will monitor the potential energy efficiency of this new manufactured home.
At the laboratory's urging, the manufactured home is the first constructed of structural insulated panels, or SIPs.
The panel's foam core better insulates and controls air leakage than traditional building materials and less lumber is used to build the homes.
Through DOE's Building America program, researchers will analyze and rep
