GM Revs up Diesel Combustion Modeling on Titan Supercomputer

https://vimeo.com/260126956 Most car owners in the United States do not think twice about passing over the diesel pump at the gas station. Instead, diesel fuel mostly powers our shipping trucks, boats, buses, and generators—and that is because diesel engines are about 10 percent more fuel-efficient than gasoline, saving companies money…

OLCF Postdoc Fuses the Gap Between Experiment and Computation

Ada Sedova, a postdoctoral research associate at the Oak Ridge Leadership Computing Facility (OLCF), develops computational calculations for supercomputing codes. In front of the OLCF’s Titan supercomputer, Sedova displays a spectrum from her experimental work, measuring the vibrational frequency of nucleobases (bases of DNA and RNA) at the Spallation Neutron…

Sodium Shakedown in Dopamine Research

The chemical neurotransmitter dopamine is critical to sending and receiving signals in the nervous system linked to motor movements, learning, and habit formation, which is why many therapies for drug addiction and diseases related to the aging brain, such as Parkinson’s disease, target dopamine uptake. Central to uptake is the…

How Hot Is Too Hot in Fusion?

Fusion, the energy that powers the stars, might one day provide abundant energy here on Earth. In a nuclear fusion reactor, the hot, charged gas known as plasma reaches out of this world temperatures at 150 million degrees Celsius, or 10 times hotter than the center of the sun. The…

Supercomputing, Experiment Combine for First Look at Magnetism of Real Nanoparticle

https://vimeo.com/202250016 Barely wider than a strand of human DNA, magnetic nanoparticles—such as those made from iron and platinum atoms—are promising materials for next-generation recording and storage devices like hard drives. Building these devices from nanoparticles should increase storage capacity and density, but understanding how magnetism works at the level of…

Delving into the Dark Sky

When Mike Warren was a graduate student 20 years ago, computational astrophysicists were conducting simulations of the universe’s structure with a million particles representing large masses of matter like galaxy clusters. Simulations of galaxy formation were beginning to supplement the maps and catalogs researchers were creating with telescope and detector…
