Strain in silver nanoparticles creates unusual 'twinning'

August 28, 2012 4:26 am | News | Comments

When twins are forced to share, it can put a significant strain on their relationship. While this observation is perhaps unsurprising in the behavior of children, it is less obvious when it comes to nanoparticles. After spending close to a decade examining the structure of nanowires made of pure silver, scientists at Argonne National Laboratory have discovered a set of unusual behaviors in nanocrystals with a strained, five-fold symmetry formed by "twinning" in the crystal structure.

August 16, 2012 9:38 am | News | Comments

Following a six-month land-based campaign in the Maldives to study tropical convective clouds, the U.S. Department of Energy's second Atmospheric Radiation Measurement (ARM) mobile facility, called AMF2, is being readied for its first marine-based research campaign aboard a cargo container ship in the Pacific Ocean.

An intriguing twist in the structure of a cobalt oxide catalyst

August 15, 2012 5:41 am | by David Lindley | News | Comments

Hydrogen is a clean fuel, producing only water vapor when it burns. But generating hydrogen in large quantities and in a "green" fashion is not straightforward. Biological photosynthesis includes an efficient reaction step that splits water into hydrogen and oxygen with the help of catalysts that have been used as models for synthetic catalysts. Working at the Advanced Photon Source at Argonne National Laboratory, a team of scientists has determined the structure of one such catalyst, a complex cobalt oxide.

Grid realities cancel out some of wind power's carbon savings

May 30, 2012 7:08 am | News | Comments

Wind energy lowers carbon emissions, but adding turbines to the current grid system does not eliminate emissions proportionally, according to a report by researchers at Argonne National Laboratory. To test how wind energy affects carbon dioxide emissions, Argonne scientists modeled the Illinois electric grid and tested how more wind power would affect the system.

May 21, 2012 12:54 pm | News | Comments

Quantum physics and plant biology seem like two branches of science that could not be more different, but surprisingly they may in fact be intimately tied. Researchers at Argonne National Laboratory and the Notre Dame Radiation Laboratory at the University of Notre Dame used ultrafast spectroscopy to see what happens at the subatomic level during the very first stage of photosynthesis.

Untangling the mysteries of spider silk

May 3, 2012 3:53 am | News | Comments

Spiders weave a web even more tangled than originally thought—at least on the nanoscale level, according to a new study performed at Argonne National Laboratory. Using high-energy X-rays provided by the Advanced Photon Source, scientists peered into the structure of orb spiders' dragline silk—the chief thread that allows them to dangle precipitously off branches and window frames.

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.
