    Drought, Wetting Direction, and the Fate of Soil Carbon

    A new paper in Nature Communications, a collaboration by lead author A. Peyton Smith and others at PNNL, investigates the importance of pore-scale wetting patterns, antecedent soil moisture conditions, and other factors affecting soil carbon dynamics at every scale, from pore to core to field.

  • Hydrogen formation via nitrogenase enzyme

    The Nitroganese Nuance

    Scientists sought to understand the H2 relaxation mechanism in nitrogenase by monitoring the effects of hydrogen vs deuterium on the kinetics of H2 formation. The team discovered that a nearby H+ was actually the active partner in the production of H2 when it combines with the iron-hydride to make H2.

    Song Named IEEE Computer Society Early Career Honoree

    Congratulations to Shuaiwen Leon Song, from PNNL’s HPC group, who was named a recipient of IEEE Computer Society’s 2017 Technical Consortium on High Performance Computing Award for Excellence for Early Career Researchers in High Performance Computing. Song will receive the award during this year’s International Conference for High Performance Computing, Networking, Storage and Analysis, known as SC17, in Denver.

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.
