PNNL scientist Dr. Xiao-Ying Yu and her team have discovered important information about the formation of secondary organic aerosols, which are quickly becoming a primary pollutant of concern in terms of climate change.
PNNL Laboratory Director Steve Ashby attended an event marking the 20th anniversary of the Department of Energy’s National Nuclear Security Administration Nuclear Smuggling Detection and Deterrence program.
Researchers apply numerical simulations to understand more about a sturdy material and how its basic structure responds to and resists radiation. The outcomes could help guide development of the resilient materials of the future.
Researchers used novel methods to safely create and analyze plutonium samples. The approaches could prove influential in future studies of the radioactive material, benefitting research in legacy, national security and nuclear fuels.
In isolating the processes that drive Atlantic Multidecadal Variability, researchers found that the ocean drove stronger multidecadal variability (greater than 30 years), while the atmosphere drove weaker variability up to interdecadal time
