NERSCPowering Scientific Discovery Since 1974

Supercomputers Help Identify Efficiency-Limiting Defects in LEDs

Researchers from the University of California Santa Barbara have identified a class of point defects that act as sites for nonradiative recombination and can explain the observed reduction in efficiency of nitride-based light emitting diodes. » Read More

Cryo-EM's Renaissance

Two recent papers in Nature are representative of the renaissance currently taking place in cryo-electron microscopy—fueled by the rise of cutting-edge electron detector cameras, sophisticated image processing software and access to supercomputing resources. » Read More

A Peek Inside the Earliest Moments of the Universe

Researchers from the NPLQCD Collaboration used lattice QCD calculations to better understand the big bang nucleosynthesis process, which occurred in the first few minutes following the Big Bang, and precisely measure the nuclear reaction rate that occurs when a neutron and proton form a deuteron. » Read More

Models Help Pinpoint Material for Better Nuclear Fuel Recycling

Researchers are investigating a new material that screens out and captures for reuse xenon and krypton gases that are released during nuclear fuel recycling. The material has the potential to save energy and make reprocessing cleaner and less expensive. » Read More

Liquids and Surfaces Moving in Synergy

Berkeley Lab researchers using NERSC resources have developed a new mathematical framework that allows researchers to capture fluid dynamics at unprecedented detail. The work could be used in a range of applications, like optimizing the shape of a propeller blade and the ejection of ink droplets in printers. » Read More
