A new way to go from nanoparticles to supraparticles

September 19, 2011 5:40 am | News | Comments

Controlling the behavior of nanoparticles can be just as difficult trying to wrangle a group of teenagers. However, a new study involving Argonne National Laboratory has given scientists insight into how tweaking a nanoparticle’s attractive electronic qualities can lead to the creation of ordered uniform "supraparticles."

Argonne patents technology that increases safety of Li-ion batteries

September 16, 2011 4:25 am | News | Comments

Decoding the proteins behind drug-resistant superbugs

September 15, 2011 8:30 am | News | Comments

Penicillin and its descendants once ruled supreme over bacteria. Then the bugs got stronger, and hospitals have reported bacterial infections so virulent that even powerful antibiotics held in reserve for these cases don't work. To create the next line of defense against the most drug-resistant pathogens, scientists at Argonne National Laboratory and Texas A&M University have decoded the structure of a protein that confers drug resistance against our best antibiotics.

Scientists design self-assembled microrobots

August 9, 2011 5:22 am | by Louise Lerner | News | Comments

Physicists at the Argonne National Laboratory have coaxed microrobots to do their bidding. The robots, just half a millimeter wide, are composed of microparticles. Confined between two liquids, they assemble themselves into star shapes when an alternating magnetic field is applied.

Scientists to assemble Kbase to aid U.S. biofuel, environment efforts

July 18, 2011 9:40 am | News | Comments

A multi-institutional team has been awarded government funding to create out of many separate streams of biological information a single, integrated cyber-"knowledgebase" (called Kbase) focused specifically on two fundamentally important forms of life.

Diagnosing advanced batteries for a longer life

July 14, 2011 5:31 am | News | Comments

Imagine a battery that truly does keep on going and going—and not for just a few years, but close to decades. At Argonne National Laboratory, materials scientist Daniel Abraham works to do just that for lithium-ion batteries.

Plutonium tricks cells by 'pretending' to be iron

July 11, 2011 5:23 am | News | Comments

Plutonium gets taken up by our cells much as iron does, even though there's far less of it to go around. Researchers at Argonne National Laboratory and Northwestern University have identified a new biological pathway by which plutonium finds its way into mammalian cells. The researchers learned that, to get into cells, plutonium acts like a "Trojan horse," duping a special membrane protein that is typically responsible for taking up iron.

Using sound to mount microcrystals for X-ray diffraction

July 7, 2011 4:56 am | News | Comments

Brookhaven National Laboratory researchers are using high-frequency sound waves in conjunction with extremely bright X-rays to get a look at the atomic structures of the complex biological molecules that make our bodies work.

Argonne electrifies energy storage research

June 30, 2011 4:18 am | News | Comments

A multidisciplinary team of researchers at Argonne National Laboratory is working to develop advanced energy storage technologies to aid the growth of a nascent U.S. battery manufacturing industry, help transition the U.S. automotive fleet to one dominated by plug-in hybrid and electric passenger vehicles, and enable greater use of renewable energy technologies.

Putting the 'fuel' in biofuels

May 26, 2011 5:07 am | News | Comments

Recent discussions of methods by which biomass—grasses, trees, and other vegetation—could be turned into fuel makes a lot of sense in theory. Plant matter is composed of energy-intensive carbohydrates, but even now scientists still don't have the perfect solution for converting plant sugars into combustible fuels.

Nanoparticles help scientists harvest light with solar fuels

May 19, 2011 7:58 am | News | Comments

The humble alga, hated by boaters and pool owners, may someday help provide us with the raw machinery to power our appliances. A group of scientists at Argonne National Laboratory, led by chemist Lisa Utschig, has linked platinum nanoparticles with algae proteins, commandeering photosynthesis to produce hydrogen instead. The system produces hydrogen at a rate five times greater than the previous record-setting method.

New isotope found for climatological dating

May 12, 2011 4:53 am | News | Comments

Radioactive dating is used to determine everything from the age of dinosaur fossils to Native American arrowheads. A new technique recently developed at the U.S. Department of Energy's Argonne National Laboratory may give researchers another tool for radioactive dating that could be of particular use in studying the history of climate change.

Combining gas and diesel engines could yield best of both worlds

May 5, 2011 4:37 am | News | Comments

It may be hard to believe, but the beloved gasoline engine that powers more than 200 million cars across America every day didn't get its status because it's the most efficient engine. Diesel engines can be more than twice as efficient, but they spew soot and pollutants into the air. Could researchers at Argonne National Laboratory engineer a union between the two—combining the best of both?
