Revealing Reclusive Recombination Mechanisms

Researchers used NERSC to produce critical new insights into the fundamental mechanisms behind highly efficient photovoltaics based on hybrid perovskites. In one of two studies, UC Santa Barbara researchers used first-principles calculations to find that (surprisingly) recombination rates in these materials were as high as conventional solar cell materials.

NERSC-9 Facility Upgrade Begins Mid-December

Construction activities will begin in mid-December along Cyclotron Road near Building 59. Temporary fencing installation along the Cyclotron Road sidewalk won’t impede pedestrian access. This supports the deployment of the Perlmutter (NERSC-9) HPC system and consists of mechanical and electrical equipment installation. Construction is planned through 2020. Call Ben Maxwell (x5573) or Randy Farrell (x4618) with questions.

Climate Simulations Project Wetter, Windier Hurricanes

New supercomputer simulations by climate scientists at Lawrence Berkeley National Laboratory have shown that climate change intensified the amount of rainfall in recent hurricanes such as Katrina, Irma, and Maria by 5 to 10 percent. They further found that if those hurricanes were to occur in a future world that is warmer than present, those storms would have even more rainfall and stronger winds. More>

Ice Sheet Simulations at NERSC Shed Light on Sea Level Rise Projections

The BISICLES (Berkeley Ice Sheet Initiative for CLimate ExtremeS) program is an important tool for research into how the loss of Antarctic ice shelves could contribute to sea level rise. The simulations shown here, created at NERSC by Lab scientist Dan Martin, demonstrate the millennial-scale vulnerability of the ice sheet due solely to the loss of its ice shelves. More>

NERSC Recognized by NASA for Contributions to Planck Mission

NERSC staff were recently honored with a NASA Group Achievement Award for their high-performance computing support of the Planck Space Mission, which pushed the boundaries of supercomputing as well as cosmology. More>

Lab Teams Are Gordon Bell Prize Finalists

Among the finalists for the prestigious Gordon Bell Prize are two Berkeley Lab teams who are using the “Summit” supercomputer at Oak Ridge National Lab. Prabhat plans to use AI software to predict how extreme weather is likely to change in the future. André Walker-Loud and Pavlos Vranas are developing improved algorithms to help predict the lifetime of neutrons and answer fundamental questions about the universe. More>

Batteries Get a Boost from ‘Pickled’ Electrolytes

Battery researchers at Argonne National Laboratory have used computer simulations at NERSC to help reveal the mechanism behind a common additive known to extend the life of lithium-ion batteries. At its heart is a chemical reaction similar to pickling. More>

Lab-Developed Digital Library is a Game Changer for Environmental Research

ESS-DIVE is a new digital archive that serves as a repository for hundreds of DOE-funded research projects under the agency’s Environmental System Science umbrella, which includes the Subsurface Biogeochemical Research and Terrestrial Ecosystem Sciences programs. The digital library was built by a collaboration of scientists from the Computational Research Division, Earth and Environmental Sciences Area, and NERSC. More>

Berkeley Lab User Facilities Prominent in SSURF Annual Meeting

Representatives from the Lab’s five national user facilities attended the Society for Science at User Research Facilities (SSURF) Annual Meeting in late June. JGI Director Nigel Mouncey presented, “How Facilities Can Partner With Industry to Strengthen the Scientific Infrastructure.” The Molecular Foundry’s Alison Hatt, who also serves on the SSURF Board of Directors, moderated a session.

NOvA Experiment Sees Strong Evidence for Antineutrino Oscillation

The NOvA particle physics experiment drew heavily upon the computing power at Berkeley Lab’s National Energy Research Scientific Computing Center (NERSC) in a new analysis that took a deep dive into experimental data about neutrino interactions and found evidence of antineutrino oscillation. More>
