Thermoelectric materials: recycling energy
OAK RIDGE, Tenn., March 30, 2011 For some years now, NASA has been using what are called thermoelectric materials to power its space probes. The probes travel such great distances from our sun that solar panels are no longer an efficient source of power. So NASA imbeds a nuclear material in a radioisotope thermal generator, where it decays, producing heat energy. That energy is then converted by thermoelectric materials into the electricity that powers the space probe. The same technology is now being explored for more earthly applications, for example, to capture heat lost in the exhaust of automobiles to produce electricity for the vehicle.

Computational scientists use supercomputers at Oak Ridge to explore ice sheet dynamics
OAK RIDGE, Tenn., Feb. 25, 2011 Recently, Rhode Island-sized chunks of ice have separated from Greenland and Antarctica, garnering worldwide attention. But is this calving due to typical seasonal variations or a long-term warmer world? Climate scientists already use ice sheet models to better understand how ice loss affects sea levels; however, those models are not easily adapted for use in global climate models. In August the Scalable, Efficient, and Accurate Community Ice Sheet Model project began on Jaguar, one of the world's fastest supercomputers, at Oak Ridge National Laboratory. SEACISM's aim is to use state-of-the-art simulation to predict the behavior of ice sheets under a changing climate by developing scalable algorithms.

Cited in the SOTU
OAK RIDGE, Tenn., Jan. 26, 2011 President Obama, in his State of the Union address Tuesday, cited work being performed at the Department of Energy's Oak Ridge National Laboratory as an example of cutting edge research aimed at solving the energy challenge. His text: "... if they assemble teams of the best minds in their fields, and focus on the hardest problems in clean energy, we'll fund the Apollo Projects of our time. At the California Institute of Technology, they're developing a way to turn sunlight and water into fuel for our cars. At Oak Ridge National Laboratory, they're using supercomputers to get a lot more power out of our nuclear facilities. With more research and incentives, we can break our dependence on oil with biofuels, and become the first country to have 1 million electric vehicles on the road by 2015."

Neutrons 'go viral' at ORNL
OAK RIDGE, Tenn., Jan. 21, 2011 Without a host, a virus is a dormant package of proteins, genetic material and occasional lipids. Once inside a living cell, however, a virus can latch onto cell parts and spring into action - mutating, replicating and spreading into new cells.
Neighbor lends a hand
OAK RIDGE, Tenn., Jan. 14, 2011 Scientists and engineers at the Spallation Neutron Source at Oak Ridge National Laboratory are working with the U.S. ITER Project Office at ORNL, the Japanese Atomic Energy Agency and the ITER Organization to resolve issues with a critical component of the experimental fusion energy facility ITER. The VULCAN Engineering Diffractometer at SNS is being used to examine superconducting cables for ITER's central solenoid magnet, which induces the electrical current needed to confine and shape the plasma inside the reactor.

Building gasifiers via simulation
OAK RIDGE, Tenn., Dec. 29, 2010 A team of scientists from the National Energy Technology Laboratory (NETL) is using Oak Ridge National Laboratory's (ORNL's) Jaguar supercomputer, located at the Oak Ridge Leadership Computing Facility (OLCF), to conduct high-reliability simulations of a coal gasifier in an attempt to make the potential energy alternative more efficient and reliable. The project also aims to demonstrate the impact of simulation on reducing the cost and time required to develop the zero-emissions power plants of the future.
The spin doctor
OAK RIDGE, Tenn., Dec. 29, 2010 An electron spin can be compared to the needle of a compass that points either north or south. Some electrons in a full shell point up, canceling out the electromagnetic fields of an equal number of electrons that point down.
SNS user from Johns Hopkins excited by first-day data
OAK RIDGE, Tenn., Dec. 28, 2010 Collin Broholm, a professor of physics at Johns Hopkins University in Baltimore, was clearly excited about the results he was reviewing in the control room of the wide-angular-range chopper spectrometer (ARCS) at SNS.
HTML, HFIR team with industry to find hidden stresses in materials
OAK RIDGE, Tenn., Dec. 28, 2010 Whether it's that klunky new Hummer you bought for a song, that honey of a BMW sports coupe, farm equipment from John Deere, or a pressurized water nuclear reactor, the materials from which they are made contain hidden stresses that affect safety, longevity, even energy efficiency and the environment.
Scientists, industry use neutron imaging to improve energy efficiency
OAK RIDGE, Tenn., Dec. 28, 2010 Neutron scientists at Oak Ridge National Laboratory (ORNL) are partnering with industry to enhance engine and commercial cooling technologies in hopes of making improvements that will optimize fuel and energy efficiency.
ORNL Systems Lead in Petascale Science
OAK RIDGE, Tenn., Dec. 21, 2010 Oak Ridge National Laboratory (ORNL) supercomputers continue to demonstrate their importance to the science community, offering unmatched resources to researchers exploring climate change, alternative energy sources, and the full range of critical science challenges.
Driving Blood-Flow Research at The Petascale
OAK RIDGE, Tenn., Dec. 17, 2010 Choosing directions during a road trip used to consist of passengers holding a map with arms fully extended and noses to the page trying to decipher exactly where to turn or what exit to take. Today global positioning systems lay out the route for travelers, anticipating the curves of the road, when they have to turn, and where traffic jams and inclement weather await.

OLCF Announces Approximately a Billion Hours for 2011 INCITE Projects
OAK RIDGE, Tenn., Dec. 3, 2010 The Oak Ridge Leadership Computing Facility (OLCF) will provide more than 950 million processor hours via the Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program, the U.S. government's premier supercomputing allocation, jointly managed by the Department of Energy's leadership computing facilities at Argonne and Oak Ridge National Laboratories.
Jaguar pounces on child predators
OAK RIDGE, Tenn., Nov. 30, 2010 Consumers of child pornography break the law when they download photos and videos from file-sharing networks. But police are more concerned with the porn producers uploading the files. Every new posting means a child is in harm's way. To accelerate the acquisition of information needed to arrest child predators, law enforcement officers have teamed with data analytics experts at Oak Ridge National Laboratory for a project that will use Jaguar, one of the world's fastest supercomputers, to speedily analyze the activities on file-sharing networks that pinpoint porn producers.
