Capturing those Beguiling BVOCs
Detecting biogenic organic compounds in the atmosphere using land data and chemistry models helps describe atmospheric particle formation and air quality

Researchers at Pacific Northwest National Laboratory and their collaborators used a "mash-up" of several models to simulate BVOCs and compare them to real-life observations. The coupled system reasonably simulated the BVOCs, and using sensitivity experiments they showed that land surface formulas in the models do influence how BVOCs are simulated, but the impact is much smaller than the influence of vegetation distribution.

The Vital Electrical Interplay between Microorganisms and Extracellular Minerals
Electron transfer strategies that have biotechnological potential

Microorganisms with electron-transfer capabilities, such as metal-reducing microorganisms, use specialized systems to exchange electrons between minerals and cells. In this review, Shi et al. summarize the underlying molecular mechanisms, such as cytochromes and nanowires, and the biotechnological applications.

Plutonium Keeps Its Electrons Close to Home
Study shows that radioactive material acts like a salt, a nuance that could benefit nuclear detectors and reactors

Extremely complex plutonium has ties to energy and security. Scientists from Pacific Northwest National Lab and Washington State University found that plutonium's behavior, in PuF4, can be attributed to the hoarding of electrons by the atoms.

Launching a New Era for NWChem
PNNL-developed computational chemistry code set to grow under new ECP project

NWChemEx: Tackling Chemical, Materials and Biomolecular Challenges in the Exascale Era was recently selected as a four-year project for the national Exascale Computing Project, known as ECP. NWChemEx will enhance the popular computational chemistry code, NWChem, to dramatically improve its scalability, performance, extensibility, and portability to take full advantage of exascale computing technologies. Dr. Thom Dunning, a Battelle Fellow with the University of Washington-PNNL Northwest Institute for Advanced Computing, is NWChemEx’s Project Director.
