The study of nanoscale material just got much easier, and the design of nanoscale technology could get much more efficient, thanks to an advance in X-ray analysis. Nanomaterials develop new physical and chemical properties, such as superconductivity and enhanced strength, when exposed to extreme pressure. A better understanding of how and when those changes occur can guide the design of better products that use nanotechnology.
Observing the evolution of a particular type of antibody in an infected HIV-1 patient has provided insights that will enable vaccination strategies that mimic the actual antibody development within the body. Spearheaded by Duke University, the multi-institution study included analysis from Los Alamos National Laboratory and used high-energy X-rays from the Advanced Photon Source at Argonne National Laboratory.
The U.S. Department of Energy's National Renewable Energy Laboratory and Argonne National Laboratory this week announced the release of the Transportation Energy Futures study, an assessment of avenues to reach deep cuts in petroleum use and greenhouse gas emissions in the transportation sector. The project suggests opportunities for 80% reductions by 2050
President Barack Obama is pushing Congress to authorize more federally funded research into clean energy technologies that can wean automobiles off oil. Obama proposed the idea of an energy security trust last month in his State of the Union address, but he was putting a price tag on the idea during a trip Friday to the Argonne National Laboratory outside Chicago—$2 billion over 10 years.
The U.S. Department of Energy's Argonne National Laboratory and California Lithium Battery Inc. (CalBattery), a Los Angeles Cleantech Incubator portfolio company, announced that they have signed a licensing agreement for an Argonne-developed, silicon-graphene composite anode material for high-energy lithium batteries.
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.
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.
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.
More than eight years of effort by Advanced Photon Source (APS) physicists, engineers, and technicians culminated on Jan. 21, 2013, with the production of the first X-rays from the prototype of a novel superconducting undulator (SCU), which has been installed in the APS electron accelerator and storage ring at Argonne National Laboratory. It is the first such SCU operated at a third-generation synchrotron X-ray facility.
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.
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.
Changes in the R&D environment are driving research managers to look at different ways to support and grow their organizations.
For the first time, scientists witnessed the details of the full, ultrafast process of liquid droplets evolving into a bubble when they strike a surface. Their research determined that surface wetness affects the bubble's fate. This research could one day help eliminate bubbles formed during spray coating, metal casting, and inkjet printing.
Researchers have mapped the precise 3D atomic structure of a thin protein filament critical for cells in the inner ear and calculated the force necessary to pull it apart. Their findings open avenues for research in fields related to noise-induced hearing loss and certain genetic diseases.
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.
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.
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.
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.
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.
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.
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.
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.
A Horizon Lines container ship outfitted with meteorological and atmospheric instruments installed by scientists from Argonne National Laboratory and Brookhaven National Laboratory will begin taking data for a yearlong mission aimed at improving the representation of clouds in climate models.
A University of Arkansas physicist and his colleagues have examined the lower limits of novel materials called complex oxides and discovered that unlike conventional semiconductors the materials not only conduct electricity, but also develop unusual magnetic properties.
New technologies in microelectronics and lithography typically require the presence of nanoscale polymer films in contact with a substrate. Successful engineering of these structures requires an understanding of the interplay between the dynamics of the thin film and the underlying substrate, and recent experiments at the Argonne National Laboratory’s Advanced Photon Source have produced new insights into these compositions.
