The boundary between electronics and biology is blurring with the first detection by researchers at Department of Energy's Oak Ridge National Laboratory of ferroelectric properties in an amino acid called glycine. A multi-institutional research team led by Andrei Kholkin of the University of Aveiro, Portugal, used a combination of experiments and modeling to identify and explain the presence of ferroelectricity, a property where materials switch their polarization when an electric field is...

Electron microscopy, conducted as part of the Shared Research Equipment (ShaRE) User Program at the Department of Energy's Oak Ridge National Laboratory, has led to a new theory to explain intriguing properties in a material with potential applications in capacitors and actuators. A research team led by ORNL's Albina Borisevich examined thin films of bismuth samarium ferrite, known as BSFO, which exhibits unusual physical properties near its transition from one phase to another. BSFO holds...

EPA On The Wrong Side Of Green Groups Over Coal Ash Rules
2012-04-09 09:13:32

An alliance of environmental groups is urging the Environmental Protection Agency (EPA) to push forward with new coal ash standards that it had proposed after a massive and expensive 2008 oil spill at the Tennessee Valley Authority (TVA) Kingston Fossil Plant. The group, comprised of EarthJustice, the Sierra Club, the Environmental Integrity Project, and others, filed a lawsuit against the EPA last Thursday (April 5) because the agency failed to act on the proposal it had made years...

Solar cells, light emitting diodes, displays and other electronic devices could get a bump in performance because of a discovery at the Department of Energy's Oak Ridge National Laboratory that establishes new boundaries for controlling band gaps. While complex transition metal oxides have for years held great promise for a variety of information and energy applications, the challenge has been to devise a method to reduce band gaps of those insulators without compromising the material's...

By using a novel technique to better understand mineral growth and dissolution, researchers at the Department of Energy's Oak Ridge National Laboratory are improving predictions of mineral reactions and laying the groundwork for applications ranging from keeping oil pipes clear to sequestering radium. The mineral barite was examined to understand mineral growth and dissolution generally, but also because it is the dominant scale-forming mineral that precipitates in oil pipelines and...

To better understand the fundamental behavior of molecules at surfaces, researchers at the U.S. Department of Energy's Oak Ridge National Laboratory are combining the powers of neutron scattering with chemical analysis. Scientists have a fundamental interest in how molecules behave at solid surfaces because surface interactions influence chemistry, such as in materials for catalysis, drug delivery and carbon sequestration. Understanding these interactions allows researchers to tailor...
