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.
29-Apr-2015 Special science call projects announced
EMSL's Special Science Call for Proposals ran from mid-April through September and generated 23 accepted studies. The call challenged prospective users to submit high-impact research projects that took advantage of EMSL's technical resources including RadEMSL, the Quiet Wing microscopy and NanoSIMS capabilities, and HRMAC. The research associated with the call is progressing, and the projects will soon start delivering important scientific findings.
28-Apr-2015 Ground control
The United Nations General Assembly declared 2015 the International Year of Soils. Soil is critical for food production and climate regulation. It's a complex underground ecosystem of organisms that process decaying debris to enrich the land as well as store and release carbon into the atmosphere. However, human activity and changing climate are impacting this environmental system. Scientists working at EMSL are trying to understand the complexities of soil to develop better sustainable land management to protect it.
10-Apr-2015 Bacteria tracked feeding nitrogen to nutrient-starved plants
An international team of researchers, including three from Brookhaven National Laboratory, tracked nitrogen as soil bacteria pulled it from the air and released it as plant-friendly ammonium. This eco-friendly process -- called biological nitrogen fixation -- substantially promoted growth in certain grass crops.
20-Mar-2015 Organic photovoltaics experiments showcase HPC 'superfacility' concept
A collaborative effort linking the Advanced Light Source at Lawrence Berkeley National Laboratory with supercomputing resources at NERSC and the Oak Ridge Leadership Computing Facility is yielding exciting results in organic photovoltaics research that could transform the way researchers use these facilities and improve scientific productivity in the process.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
