With help from the Titan supercomputer, an Oak Ridge National Laboratory team is peering at the chemistry and physics between the layers of superconducting materials.
The Energy Science Network, the high-speed fiber optic data pipeline that has connected all 17 U.S. national laboratories for almost 30 years, will cross the Atlantic Ocean this year. The network will link with the Large Hadron Collider (LHC) near Geneva and with other information-intensive European research projects. The network, managed by Lawrence Berkeley National […]
On the roads around the Bay Area in 2015, there’s a good chance Brandon Wood will spot one of the first commercially available hydrogen-powered passenger vehicles: Toyota’s 2015 FC (fuel cell) car. The Toyota’s fuel cells will electrochemically combine hydrogen with oxygen to generate electricity, producing water as the only chemical emission. However, drivers will […]
Matthew Brake, a principal research scientist at Sandia National Laboratories, New Mexico, estimates that several thousand researchers worldwide are striving to improve how mechanical joints are modeled on computers. Many work in laboratories led by 80 active members of the American Society of Mechanical Engineers’ Research Committee on the Mechanics of Jointed Structures, which Brake […]
For discovering significant supernova phenomena and simulation flaws, several pairs of eyes beat pages of numbers, Anthony Mezzacappa says. Data visualization has been a key tool as he and his fellow astrophysicists model the standing accretion shock instability (SASI) in core-collapse supernovae, says Mezzacappa, director of the Joint Institute for Computational Science at Oak Ridge […]
Exploring the breaking and rejoining of magnetic-field lines requires simulations and computation. A simulation’s accuracy, however, depends on various issues of scale. Magnetic reconnection’s multiscale nature exacerbates the challenge of simulating it. Early research was based entirely on fluid models in just two dimensions, since kinetic simulations were infeasible. Kinetic modeling requires the space and […]
Dragos Velicanu likes to look at just about everything from a fresh perspective. “Outside work, I like to travel, go camping, hiking, skiing – basically see the world from all elevations, seasons and angles,” says the Department of Energy Computational Science Graduate Fellowship recipient at MIT. What’s more, he’s fortunate that his advisor is Gunther […]
