The Color of Smog
New study shows the molecular details of how organic aerosol helps heat up and color the haze over megacities

Scientists at Pacific Northwest National Laboratory determined that high concentrations of nitrogen oxides influence the creation of the brown haze that hangs over the world's megacities. Their work provides new insights that can create higher accuracy climate and atmospheric models.

The Difference a Day (or Night) Makes
Studying the diel cycle gives rise to new hypotheses about microbial community behavior

In a study recently published in Frontiers in Microbiology, PNNL scientists Young-Mo Kim, Jim Fredrickson, and Tom Metz demonstrated the effect that sunlight or the absence thereof over a 24-hour period-the diel cycle-has on production of chemicals used as metabolites in microbial mats of Mushroom Springs in Yellowstone National Park. Understanding these impacts can help efforts to use microbes to produce biochemicals and bioenergy.

Shoving Protons Around
Review highlights molecular-level work involved in creating a design guide for catalysts for use of sustainable energy

In an invited review of research by the Center for Molecular Electrocatalysis,  Dr. Morris Bullock and Dr. Monte Helm at Pacific Northwest National Laboratory showed how shoving protons can enable iron and nickel to replace platinum in catalysts, providing a less expensive and more readily available base for sustainable storage of renewable energy.

CENATE: A Computing Proving Ground
New center at PNNL will shape future extreme-scale computing systems

The recently launched Center for Advanced Technology Evaluation, dubbed CENATE, at PNNL is a first-of-its-kind computing proving ground. Before setting the next-generation, extreme-scale supercomputers to work solving some of the nation’s biggest problems, CENATE’s evaluation of early technologies to predict their overall potential and guide their designs will help hone future technology, systems, and applications before these high-cost machines make it to production.
