Building gasifiers via simulation
December 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 spin doctor
December 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
December 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
December 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
December 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
December 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
December 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.
December 10, 2010 — The crushing of 180 digitally manufactured (DM) titanium mesh spheres has culminated in a $50,000 DARPA prize for a University of California at Santa Barbara team, who came up with the most accurate predictive model of the components' properties.
OLCF Announces Approximately a Billion Hours for 2011 INCITE Projects
December 03, 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
November 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.
