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

The August 2015 issue of Computer, focused on “Irregular Applications,” owes its editorial direction to two guest editors: Antonino Tumeo, of ACMD Division’s HPC group, and John Feo, who recently rejoined PNNL as the new co-director of the Northwest Institute for Advanced Computing. In the issue, Tumeo and Feo take a holistic look at irregular behaviors in computing systems at all layers of the software and hardware stack. They also provided the magazine’s introduction and selected the featured articles, including one co-authored by Mahantesh Halappanavar, from ACMD Division’s Data Sciences group.
