29-Jun-2006 Lightweight materials pave the road for energy-efficient vehicles
In efforts to shorten the long road to fuel efficiency, researchers at Pacific Northwest National Laboratory are working to develop cost-effective, high-strength, lightweight materials that will reduce vehicle weight without compromising cost, performance or safety.
29-Jun-2006 Catalysis: The science behind sustainable energy
About 60 percent of the things we wear or use are produced by processes that depend on catalysis. Catalysts are substances that modify chemical reaction rates and remain unchanged afterward.
Catalyst technologies affect nearly all areas of the chemical and petroleum industries with an economic impact estimated at more than $10 trillion per year worldwide. Now more than ever, innovative and improved catalyst technologies are in demand for new energy production processes to ease the United States' dependence on imported resources.
12-Jun-2006 Managing the Soviet legacy
An intact nuclear weapon is stolen and detonated. A terrorist group somehow steals, purchases, or produces fissile material and fabricates a crude bomb, called an improvised nuclear device, which the group threatens to detonate if its demands are not met.
12-Jun-2006 Science for security
Since the terrorist attacks of September 11, 2001, national security has become a priority mission of the Department of Energy. This mission, which in addition to public safety focuses on the protection of America's economic and energy security assets, is supported by an increasingly robust program of technological innovation.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
