Zeolites: Exploring molecular channels  
Scientists at PNNL's Institute for Integrated Catalysis are studying the fundamental mechanics of zeolites - crystalline structures that play a key part in catalysis. This short video addresses the study and synthesis of these important materials.  
First complete genomes reveal microorganism's role in global carbon cycle   
Collaborators: University of California, Berkeley; The Ohio State University; Columbia University; DOE Joint Genome Institute; Lawrence Berkeley National Laboratory 

Scientists working at EMSL, the Environmental Molecular Sciences Laboratory at PNNL, reconstructed the first complete genomes for Archaea, a domain of single-celled microorganisms, using cultivation-independent methods. The study revealed that Archaea in the terrestrial subsurface contribute primarily to carbon and hydrogen cycling, suggesting these organisms may be involved in processing the sizeable reservoir of buried organic carbon. This research was published in Current Biology.  

Could computers reach light speed?  

Light waves trapped on a metal's surface travel nearly as fast as light through the air. New PNNL research shows surface plasmons travel far enough to possibly be useful for ultra-fast electronic circuit interconnects. Researchers captured the waves on video, moving at least 250 microns across the surface. Because circuit interconnects based on these waves could be much faster than current interconnects, this basic research - published in the journal Nano Letters - could lead to faster computer circuits and provide significant advances in the chemical, biological and health fields

Research at Tibetan glacier measures historic trends and identifies soot emission sources 
Collaborators: Chinese Academy of Sciences 

Soot from burning biomass and fossil fuels leaves a historical record frozen in snow and ice. Researchers designed a unique climate model tracer tagging technique to identify the particles' sources and the cause of their historical trends. Published in Atmospheric Chemistry and Physics, results show that soot recorded in a southeastern Tibetan glacier, which has been increasing in recent decades, primarily originated in South Asia during non-monsoon months

HPC system modeling: Depicting interplay between energy efficiency and resiliencies   
Collaborators: University of California, Riverside; Marquette University 

To improve energy efficiency and performance on future exascale computing systems, scientists examined advanced high-performance computing systems and determined that undervolting improved system failure rates. The undervolting method does not require modifying existing hardware or using pre-production machines and has shown positive results toward achieving a cost-efficient, energy-savings implementation for the HPC field. The paper documenting this first-of-its-kind work was presented at the 29th IEEE International Parallel & Distributed Processing Symposium

Unique materials for fundamental studies in energy production and storage   

Creating catalysts that produce biofuels on a massive scale requires materials design and testing. With a new soft landing instrument developed a PNNL, simple surfaces and complex architectures may be built to screen for properties - important in supercapacitors, sensors and batteries - at speeds not possible before. "We can now control complex ionic building blocks and their placement on surfaces at rates that make new fundamental studies possible," said PNNL Laboratory Fellow Julia Laskin. This research was published in the journal Analyst.
