Tiny Particles Have Outsize Impact on Storm Clouds, Precipitation
Tiny particles fuel powerful storms and influence weather much more than has been appreciated, according to a study by PNNL scientists and colleagues in the journal Science.
Increasing Tree Mortality in a Warming World
A mix of factors is contributing to an increasing mortality rate of trees in the moist tropics, where trees are dying at about twice the rate they were 35 years ago.
Providing International Guidance to Achieve Remediation "End States"
An International Atomic Energy Agency effort, chaired by PNNL's Mike Truex, will help inform the process for achieving successful end states at contaminated sites worldwide.
Plutonium Experiment Opens New Research Possibilities
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.
Imaging Goes Underground at the Hanford site
"It's sort of like using infrared goggles to see heat signatures in the dark, except this is underground." PNNL and CHPRC implemented a state-of-the-art approach to monitor the process of remediating residual uranium at Hanford's 300 Area.
Radioactive Waste Within Reach
Installing new access holes (up to 6 feet in diameter) could reduce the overall time and cost to retrieve waste from Hanford's underground storage tanks, according to a structural analysis of the tank domes by PNNL and Becht Engineering.
Wasteform Development Laboratory
Researchers in this lab investigate glass, glass-ceramic, grout, metal, and metal-ceramic wasteforms that will withstand corrosion over geologic time. This includes supporting the nation's nuclear waste vitrification efforts at Hanford.
Water: Finding the Normal within the Weird
Water is unlike other substances because its solid form — like this iceberg — is less dense than its liquid form — like this ocean. Scientists are studying other weird properties of water.
