    Particles Carry Toxic Pollutants Far from Home

    Combining state-of-the-art atmospheric modeling with the latest measurements-based findings, researchers at PNNL found that toxic particles can last longer and travel much farther than previous models predicted. The new insights indicate an estimate of global lung cancer risk from these pollutants four times higher than previously thought.

    For Biofluids, a New Fast Automated Analysis

    A recent paper co-authored by scientists from PNNL describes a novel analytical surveillance platform and its evaluation in large-cohort exposure assessment and metabolite screening.

    Tipping Water: Finding the Balance Between Keeping Molecules Whole or Splitting Them on Oxides

    Scientists at Pacific Northwest National Laboratory definitively resolved a long-standing controversy and showed that molecular water is more stable on titania surface than the hydroxyl fragments.

    A Publishing Machine

    Roberto Gioiosa, a research scientist with PNNL’s High Performance Computing group, has been a publishing machine with several papers slated for presentation at major computing conferences, including IPDPS 2017, AsHES 2017, and CCGRID 2017, as well as a chapter in the recently released book, Rugged Embedded Systems: Computing in Harsh Environments.

Our researchers advance the frontiers of science to study, predict, and engineer complex adaptive systems related to Earth, energy, and security. Our investigations inhabit every scale. We study the vast whirl of aerosol-laden clouds; the complex shoreline interfaces of land and sea; the mysterious microbiomes that teem just beneath the Earth’s surface; and the myriad of molecules busy on surfaces just angstroms wide.

We investigate elemental chemical and physical processes, including new catalysts that speed up the efficiency of renewable fuels. We study climate system dynamics to predict the effects of climate change. We design and synthesize the functional and structural materials of the future, including robust metal foils thinner than a human hair.

We are proud to host two unique DOE user facilities. EMSL facilitates molecular-level investigations into the physical, chemical, and biological processes that underlie the Earth’s most critical environmental issues. ARM provides a setting for climate research and instrumentation development, and is strengthened by streaming data from a worldwide complex of sensing stations.
