Diamond brightens the performance of electronic devices

March 13, 2012 4:13 am | News | Comments

While diamonds may be a girl's best friend, they're also well loved by scientists working to enhance the performance of electronic devices. Two new studies performed at Argonne National Laboratory have revealed a new pathway for materials scientists to use previously unexplored properties of nanocrystalline-diamond thin films.

New picture of atomic nucleus emerges

March 1, 2012 9:12 am | News | Comments

When most of us think of an atom, we think of tiny electrons whizzing around a stationary, dense nucleus composed of protons and neutrons, collectively known as nucleons. A collaboration between the U.S. Department of Energy's Argonne National Laboratory and Thomas Jefferson National Accelerator Facility has demonstrated just how different reality is from our simple picture.

Big, bad bacterium is an 'iron pirate'

February 21, 2012 3:53 am | News | Comments

Life inside the human body sometimes looks like life on the high seas in the 1960s, when pirates hijacked foreign vessels in search of precious metals. For Neisseria bacteria, which can cause gonorrhea and meningitis, the booty is not gold or silver but plain old iron. Until recently, scientists did not understand how these bacterial snatch iron from healthy human cells, where a protein called transferrin bind the metal in a molecular bear hug.


Small modular reactor design could be a SUPERSTAR

February 9, 2012 8:21 am | News | Comments

Though most of today's nuclear reactors are cooled by water, we've long known that there are alternatives; in fact, the world's first nuclear-powered electricity in 1951 came from a reactor cooled by sodium. Reactors cooled by liquid metals such as sodium or lead have a unique set of abilities that may again make them significant players in the nuclear industry. Argonne National Laboratory has designed a new small reactor cooled by lead.

A natural solution for transportation

February 3, 2012 3:46 am | News | Comments

As the United States transitions away from a primarily petroleum-based transportation industry, a number of different alternative fuel sources—ethanol, biodiesel, electricity, and hydrogen—have each shown their own promise. Hoping to expand the pool even further, researchers at Argonne National Laboratory have begun to investigate adding one more contender to the list of possible energy sources for light-duty cars and trucks: Compressed natural gas.

Disappearing gold a boon for nanolattices

January 27, 2012 8:05 am | News | Comments

When gold vanishes from a very important location, it usually means trouble. At the nanoscale, however, it could provide more knowledge about certain types of materials. A recent discovery that enables scientists to replace gold nanoparticles with dummy "spacers" has allowed scientists to create materials with never-before-seen structures, which may lead to new properties.

Ironing out the details of the Earth's core

December 20, 2011 2:50 am | News | Comments

Identifying the composition of the Earth's core is key to understanding how our planet formed and the current behavior of its interior. While it has been known for many years that iron is the main element in the core, many questions have remained about just how iron behaves under the conditions found deep in the Earth. Until now.

Hints of the Higgs show in latest analyses

December 14, 2011 8:39 am | News | Comments

Two experiments at the Large Hadron Collider have nearly eliminated the space in which the Higgs boson could dwell, scientists announced Tuesday. However, the ATLAS and CMS experiments see modest excesses in their data that could soon uncover the famous missing piece of the physics puzzle.

A more efficient way to make molecular hydrogen

December 9, 2011 3:17 am | News | Comments

When it comes to the industrial production of chemicals, often the most indispensable element is one that you can't see, smell, or even taste. It's hydrogen, the lightest element of all. Researchers at Argonne National Laboratory have developed an efficient two-step process that electrolyzes hydrogen atoms from water molecules before combining them to make molecular hydrogen.

Unlocking algal secrets may help clean up radioactive isotopes

December 1, 2011 3:33 am | News | Comments

Using the Advanced Photon Source at Argonne National Laboratory, a group of Northwestern University and Argonne scientists have figured out the secrets of algae that can preferentially take up strontium over calcium—a task so difficult that it's not easily done even in a laboratory. The algae could form the basis of new technologies to clean up contaminated land or water.

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.

Batteries get a quick charge with new anode technology

November 3, 2011 4:55 am | News | Comments

A breakthrough in components for next-generation batteries could come from special materials that transform their structure to perform better over time. A team of researchers at Argonne National Laboratory discovered that nanotubes composed of titanium dioxide can switch their phase as a battery is cycled, gradually boosting their operational capacity.

Solar concentrator increases collection with less loss

November 2, 2011 9:44 am | News | Comments

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.
