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.

Bernstein Co-Authors Book Chapter that Aims to Guide Microbial Community Engineering

Dr. Hans Bernstein, a Linus Pauling Fellow at Pacific Northwest National Laboratory, and his colleagues at Montana State University have reconciled traditional process engineering principles with ecological theories to help guide the future of microbial community engineering. They laid out their approach in Chapter 15 of Biotechnology for Biofuel Production and Optimization, published by Elsevier.

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.

Taking Action for Resilient Cyber Systems
Demo and workshop paper to showcase novel graph model at ACM Conference on Computer and Communications Security

In Action Recommendation for Cyber Resilience, a PNNL-led team of computer scientists and mathematicians showcases the advantages of using a graph-based approach for reasoning about computing system resiliency. Their work aims to mitigate targeted cyber attacks that can disastrously impede proper operations of computing services and systems. The work will be featured as both a workshop paper and demonstration at the 22nd ACM Conference on Computer and Communications Security, where the demo will model the cyber enterprise of a fictional small e-commerce company in both a software simulation and inside the Amazon Cloud.
