Argonne scientist energizes quest for lost Leonardo da Vinci painting

Perhaps one of Leonardo da Vinci's greatest paintings has never been reprinted in books of his art. Known as the "Battle of Anghiari," it was abandoned and then lost—until a determined Italian engineer gave the art world hope that it still existed, and a physicist from Argonne National Laboratory developed a technique that may reveal it to the world once again.

A specialized piece of glass called a luminescent solar concentrator can intensify incoming light. The green and orange rings are produced by its fluorescence.
New solar cell technology gives light waves “amnesia”

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."

Argonne physicist Zheng-Tian Lu (in back) and his team (from left to right: Arjun Sharma, Wei Jiang, Kevin Bailey, and Guomin Yang) stand with the ATTA device, which measures individual atoms of the isotope Krypton-81 as part of an effort to model underground aquifers and predict how fast they refill.
Krypton-81 isotope can help map underground waterways

Cataloguing underground waterways, some of which extend for thousands of miles, has always been difficult—but scientists at Argonne National Laboratory are mapping them with some unusual equipment: lasers and a rare isotope.

“There’s a delicate balance you have to strike,” said Argonne physicist Byeongdu Lee, who led the characterization of the supraparticles using high-energy X-rays provided by Argonne’s Advanced Photon Source. “If the attractive Van der Waals force is too strong, all the nanoparticles will smash together at once, and you’ll end up with an ugly, disordered glass. But if the repulsive Coulomb force is too strong, they’ll never come together in the first place.”
A new way to go from nanoparticles to supraparticles

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 National Laboratory, working with Advanced Magnet Lab in Florida, has received an award to develop superconducting drive generators for windmills.
Powering wind energy with superconductivity

Advanced Magnet Lab, located in Palm Bay, Florida, is leading a project to develop the first fully superconducting direct-drive generator for large wind turbines with the goal of significantly reducing the cost of wind energy.

The structure of NDM-1 shows the protein's enlarged active site, which lets it latch onto and disable a broad range of antibiotics.
Decoding the proteins behind drug-resistant superbugs

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.

New materials engineering labs see early success

After only a few months of work, a small group of researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory has successfully scaled up the production of a new molecule that protects advanced lithium-ion batteries from thermal overcharge.

City of Chicago won't sweat the flu with Argonne's help

Emergency preparedness experts at Argonne National Laboratory have helped the Chicago department plan its response to potential catastrophe, including swine and bird flu epidemics, plague outbreaks and anthrax bioterrorism.

The goal of this collaboration is to develop a Systems Biology Knowledgebage (KBase), designed to accelerate our understanding of microbes, microbial communities, and plants.
New knowledgebase will enable energy and environmental innovations

Last month, the U.S. Department of Energy announced a multi-institutional effort composed of leading scientists from several institutions, including Argonne National Laboratory. The goal of this collaboration is to develop a Systems Biology Knowledgebase (KBase), designed to accelerate our understanding of microbes, microbial communities and plants.

Brain vasculature, coupled continuum-atomistic simulation: Platelets aggregation on the wall of aneurysm where yellow particles are active platelets, red particles are inactive platelets. Streamlines depict instantaneous velocity field. (i) Onset of clot formation; (ii) Clot formation progresses in time and space, detachment of small platelet clusters due to shear-flow is observed.
Showcasing award-winning scientific visualizations

Computer visualizations of arterial blood flow and the dynamics of early galaxy formation, both created by researchers at Argonne National Laboratory, have won OASCRs at this year's Scientific Discovery through Advanced Computing program conference in Denver.
