Vortex pinning could lead to superconducting breakthroughs

February 13, 2013 8:15 am | News | Comments

A team of researchers announced findings last week that may represent a breakthrough in applications of superconductivity. The team discovered a way to efficiently stabilize tiny magnetic vortices that interfere with superconductivity—a problem that has plagued scientists trying to engineer real-world applications for decades. The discovery could remove one of the most significant roadblocks to advances in superconductor technology.

New magnetoelectric materials classes may improve computing

February 8, 2013 8:12 am | by Jared Sagoff, Argonne National Laboratory | News | Comments

Research by an international team of physicists has produced new methods for controlling magnetic order in a particular class of materials known as "magnetoelectrics", which have their magnetic and electric properties couple to each other. This link offers the possibility of controlling electric behavior with a magnetic signal, or vice versa. Scientists recently demonstrated this ability in europium-titanium oxide.

X-rays shine light on mystery of Picasso's paints

February 6, 2013 3:23 pm | News | Comments

The Art Institute of Chicago teamed up with Argonne National Laboratory to help unravel a decades-long debate among art scholars about what kind of paint Picasso used to create his masterpieces. The results add significant weight to the widely held theory that Picasso was one of the first master painters to use common house paint rather than traditional artists' paint.

January 15, 2013 4:37 pm | News | Comments

In a case of the Goldilocks story retold at the molecular level, scientists at Argonne National Laboratory and Northwestern University have discovered a new path to the development of more stable and efficient catalysts. The research team sought to create "nanobowls"—nanosized bowl shapes that allow inorganic catalysts to operate selectively on particular molecules.

Chaotic “spin vortices” could lead to new computer memories

January 3, 2013 7:56 am | News | Comments

In science, just like in life, sometimes creating the most effective organization depends on being able to handle just a bit of chaos first. Scientists at Argonne National Laboratory have used alternating magnetic fields to control the behavior of "spin vortices" trapped in small dots made from iron and nickel that can be magnetized in two separate ways.

The U.S. Department of Energy has announced that a multipartner team led by Argonne National Laboratory has been selected for an award of up to $120 million over five years to establish a new Batteries and Energy Storage Hub. The Hub will combine the R&D firepower of five DOE national laboratories, five universities, and four private firms in an effort aimed at achieving advances in battery performance.

High-pressure science gets super-sized

October 24, 2012 7:47 am | News | Comments

The study of materials at extreme conditions took a giant leap forward with the discovery of a way to generate super high pressures without using shock waves whose accompanying heat turns solids to liquid. This discovery will allow scientists, for the first time, to reach static pressure levels exceeding four million atmospheres, a high-pressure environment where new compounds could be formed, materials change their chemical and physical properties, and metals become insulators.

The minimal microbe

October 19, 2012 1:27 pm | News | Comments

To study microbes and the complex communities they form in the environment, Argonne National Laboratory and three other national laboratories are collaborating to build a research tool called the Systems Biology Knowledgebase, or KBase. KBase aims to help with current data issues facing systems biology, but its goal is larger than data integration. The team seeks to advance research in two broad, important areas: plants and microbes.

An affordable way to generate medical isotopes

October 15, 2012 11:49 am | News | Comments

Scientists at Argonne National Laboratory have developed a safe and affordable way to ensure a reliable U.S. supply of certain medical isotopes. Although the invention is at a conceptual stage, it has the potential to provide critical medical diagnostic material for small regional hospitals.

Synchrotrons play role in Nobel prize research

October 12, 2012 12:04 pm | by Glenn Roberts Jr., SLAC | News | Comments

The winners of the 2012 Chemistry Nobel Prize won for their work in revealing the structure and functioning of a key protein complex on the surface of human cells that has been a target for drug development. Their main tool for this research was X-ray crystallography, which is performed with X-ray synchrotrons. But as the researchers would discover, not all synchrotrons are created equal.   

X-ray diffraction method observes thin films without damaging them

October 10, 2012 5:08 pm | News | Comments

The theoretical and experimental framework of a new coherent diffraction strain imaging approach was recently developed by scientists at IBM and Argonne National Laboratory. The new technique is capable of imaging lattice distortions in thin films nondestructively at spatial resolutions of less than 20 nm using coherent nanofocused hard X-rays.

Scientists study bridge over troubled water

October 8, 2012 7:58 am | News | Comments

Over a hundred years ago, English aristocrat William Armstrong used electricity to build a bridge out of water. It was only an inch or so across, but the physics behind it has entranced scientists for the past century and more. Fortunately, a new experiment at Argonne National Laboratory may shed light on the properties of the "flowing water bridge" and perhaps help resolve an old dispute about the physical nature of water.

Ames Laboratory finds ordered atoms in metallic glasses

October 3, 2012 4:50 am | News | Comments

Glass materials may have a far less randomly arranged structure than formerly thought. Over the years, the ideas of how metallic glasses form have been evolving, from just a random packing, to very small ordered clusters, to realizing that longer range chemical and topological order exists. A team of scientists at the Ames Laboratory has been able to show for the first time there is some organization to these structures.

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.
