Materials scientists watch electron 'melt'

November 22, 2011 3:30 am | News | Comments

When a skier rushes down a ski slope or a skater glides across an ice rink, a very thin melted layer of liquid water forms on the surface of the ice crystals, which allows for a smooth glide instead of a rough skid. In a recent experiment, scientists have discovered that the interface between the surface and bulk electronic structures of certain crystalline materials can act in much the same way.

DOE captures fugitives to reduce its carbon emissions

November 16, 2011 10:00 am | News | Comments

In terms of emissions, just one pound of sulfur hexafluoride, a nontoxic gas used in electric insulation, is equivalent to about 11 tons of carbon dioxide. Energy Department experts are hunting down this and other fugitive carbon emissions and have already prevented the release of 600,000 metric tons of carbon equivalent.

Miniaturizing nuclear recycling experiments

October 19, 2011 9:36 am | News | Comments

Designing better ways to recycle spent nuclear fuel could make nuclear energy a safer solution to the global energy problem, but there are a lot of gaps in our chemical knowledge—and it's difficult to get those answers when the experiments involve radioactive material. Scientists at Argonne National Laboratory have one answer: Shrink the whole experiment down—to microliters.

Solar cell technology gives light waves 'amnesia'

September 27, 2011 4:10 am | News | Comments

For years, scientists have dealt with the problem of trying to increase the efficiency and drive down the cost of solar cells. Now researchers have hit upon a new idea—trying to give the light collected by solar cells a bit of "amnesia." At Argonne National Laboratory, researchers have investigated the use of fluorescent plastics called luminescent solar concentrators (LSCs) that can be used to lower the cost of electricity from solar cells.
