19-Jan-2016 ORNL researchers use neutrons to gain insight into battery inefficiency
Scientists at Oak Ridge National Laboratory are improving the lifetimes of rechargeable batteries that run on lithium, a small atom that can pack tightly into graphite anode materials. The valuable ions are depleted as a battery charges, and they are also lost to the formation of a thin coating on a battery's anode during initial charging. ORNL researchers used two powerful neutron science facilities to try to understand the dynamics behind this phenomenon.
15-Jan-2016 ORNL's thermal cameras snoop beneath surfaces to reveal materials' secrets
In 1995, the Department of Energy's Continuous Fiber Ceramic Composite program, led by Oak Ridge National Laboratory, bought a high-speed infrared camera -- one of the first available for purchase outside the military. Since then, ORNL has acquired at least 10 additional IR cameras for use in a spectrum of projects. The cameras have mapped changing temperatures as heat flows through objects from gears to artwork.

Scientists from the US Department of Energy's Princeton Plasma Physics Laboratory (PPPL) and other national laboratories joined colleagues from around the world at the celebration for the first plasma of the Wendelstein 7-X (W7-X) stellarator at the Max Planck Institute in Greifswald, Germany.
15-Dec-2015 Schweickhard 'Schwick' von Goeler dies at 84
Schweickhard 'Schwick' von Goeler, an award-winning physicist at the US Department of Energy's Princeton Plasma Physics Laboratory (PPPL) for more than 35 years and the inventor of numerous X-ray diagnostics used in fusion experiments worldwide, died of leukemia on Dec. 6 in Springfield, Massachusetts. He was 84.
16-Nov-2015 PPPL to design a high-resolution diagnostic system for the National Ignition Facility
Two US Department of Energy (DOE) laboratories working on very different types of fusion experiments have begun a novel collaboration. Under the arrangement, the DOE's Princeton Plasma Physics Laboratory (PPPL) will design a diagnostic system to provide high-resolution analysis of research on the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL). This work is supported by the DOE Office of Science and LLNL.
10-Nov-2015 Atoms to engines
The Department of Energy's Oak Ridge National Laboratory, FCA US LLC, and the foundry giant, Nemak of Mexico, are combining their strengths to create lightweight powertrain materials that will help the auto industry speed past the technological roadblocks to its target of 54.5 miles per gallon by 2025.
26-Oct-2015 The silent treatment: EMSL's quiet wing
Scientists are advancing the understanding of biological and environmental systems by conducting at least part of their research in EMSL's Quiet Wing, one of the most advanced quiet laboratories in the world for high-resolution imaging capabilities. Scientists are using this facility for a wide range of research areas, including: to study bacteria in complex soil aggregates, to understand the behavior of a unique multicopper oxidase and to explore remediation methods using porous clay.
8-Oct-2015 Los Alamos-led consortium works to enhance fuel cell technology
Los Alamos National Laboratory is leading a Department of Energy- Fuel Cells Technologies Office-funded project to enhance the performance and durability of polymer electrolyte membrane (PEM) fuel cells, while simultaneously reducing their cost.
24-Sep-2015 Los Alamos explores hybrid ultrasmall gold nanocluster for enzymatic fuel cells
With fossil-fuel sources dwindling, better biofuel cell design is a strong candidate in the energy field. In research published in the Journal of the American Chemical Society, Los Alamos researchers and external collaborators synthesized and characterized a new DNA-templated gold nanocluster (AuNC) that could resolve a critical methodological barrier for efficient biofuel cell design.
8-Sep-2015 Making the most from carbon in plants
Researchers are looking for more effective ways to get at all the carbon in biomass to create more energy and biochemicals. However, a lot of the carbon is in lignin -- support tissues in plants, which makes up about a third of the biomass. International teams of scientists are utilizing EMSL's expertise and capabilities to better understand how lignin can be efficiently deconstructed to release its carbon for a more renewable and sustainable energy future.
20-Aug-2015 Carbon number crunching
A booming economy and population led China to emerge in 2006 as the global leader in fossil-fuel carbon emissions, a distinction it still maintains. But exactly how much carbon China releases has been a topic of debate, with recent estimates varying by as much as 15 percent.
12-Aug-2015 Microscopic rake doubles efficiency of low-cost solar cells
Researchers from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have developed a manufacturing technique that could double the electricity output of inexpensive solar cells by using a microscopic rake when applying light-harvesting polymers.
11-Aug-2015 Eyes on the prize
Recently, the Department of Energy Office of Science's Nanoscale Science Research Centers at Argonne, Brookhaven, Lawrence Berkeley, Los Alamos/Sandia and Oak Ridge national laboratories jointly organized a workshop at Oak Ridge National Laboratory to discuss opportunities and challenges as imaging and data sciences merge. Those efforts will likely aid the Materials Genome Initiative, which aims to speed new materials to the global marketplace.
28-Jul-2015 Rigors of the road: ORNL invention will support licensing and transport of spent nuclear fuel
With support from the US Nuclear Regulatory Commission, researchers at the Department of Energy's Oak Ridge National Laboratory have devised the Cyclic Integrated Reversible-bending Fatigue Tester. Combined with ongoing fuel transportation research, data from the CIRFT system will help facilitate cask designs and transportation protocols that ensure safe transportation of spent nuclear fuel.
27-Jul-2015 Brookhaven Lab summer school helps develop tomorrow's nuclear chemistry experts
For the past six weeks, 12 college students have had the opportunity to learn all that the US Department of Energy's (DOE) Brookhaven National Laboratory has to teach about a vital but often overlooked area of chemistry -- one that spans everything from nuclear reactors and the safe handling of nuclear material to hospital diagnostic tools and cutting-edge medical research.
29-Jun-2015 Magnetic attraction
Researchers studying a broad spectrum of science, including biofuel production processes, climate effects on carbon cycling in the soil and carbon transformations in the atmosphere will soon have access to EMSL's new 21 Tesla Fourier transform ion cyclotron resonance mass spectrometer. Scientists are eager to start getting molecular-level information for their research, and six inaugural studies were selected to use the new instrument through a Special Science Call.
27-May-2015 Carbon sequestration in New Mexico's Bravo Dome
Emplacement of carbon dioxide at the Bravo Dome gas field in New Mexico began more than 900,000 years earlier than previously estimated, according to scientists at DOE's Center for Frontiers of Subsurface Energy Security. The study documents the first field evidence for the safe long-term storage of large amounts of carbon dioxide in saline aquifers.
12-May-2015 ORNL group leads calorimeter upgrade for Large Hadron Collider experiment
Run-2 for the Large Hadron Collider -- the world's largest and most powerful particle collider -- began April 5 at CERN. In preparation, Thomas M. Cormier, who leads the LHC Heavy Ion group at Oak Ridge National Laboratory, led an upgrade of the electromagnetic calorimeter used for LHC's experiment called ALICE (for A Large Ion Collider Experiment). This detector measures the energies of high-energy electrons and gamma rays emitted from the quark-gluon plasma.
