Two forms of magnesium material were processed into tubing using PNNL’s Shear Assisted Processing and Extrusion™ technology. Both materials were found to have quite similar and improved properties—even though they began vastly different.
PNNL’s Jie Xiao was recently recognized for her outstanding contribution to basic and applied research on lithium-ion batteries and beyond by the International Automotive Lithium Battery Association.
Scientists have uncovered a root cause of the growth of needle-like structures—known as dendrites and whiskers—that plague lithium batteries, sometimes causing a short circuit, failure, or even a fire.
A new Co-Optima report describes an assessment of 400 biofuel-derived samples and identifies the top ten candidates for blending with petroleum fuel to improve boosted spark ignition engine efficiency.
PNNL researchers have created a chemical cocktail that could help electric cars power their way through extreme temperatures where current lithium-ion batteries don’t operate as efficiently as needed.
PNNL researchers demonstrate how the excitation of oxygen atoms that contributes to better performance of a lithium-ion battery also triggers a process that leads to damage, explaining a phenomenon that has been a mystery to scientists.
PNNL’s Dan Gaspar and John Holladay were part of the Co-Optima leadership team honored by DOE’s Vehicle Technologies Office. The award recognized groundbreaking work to synergistically improve fuels and engines to maximize fuel economy.
Yong Wang, a PNNL laboratory fellow, has received the 2019 Catalysis and Reaction Engineering Practice Award from the American Institute of Chemical Engineers.
Editors of the journal Emission Control Science and Technology deemed “Coating Distribution in a Commercial SCR Filter” Best Paper in 2018. The authors include PNNL's Mark Stewart, Carl Justin Kamp, Feng Gao, Yilin Wang, and Mark Engelhard.
Researchers at PNNL and their collaborators have made a significant improvement to a catalyst that is more rugged and can reduce tailpipe pollution at lower temperatures than existing methods.
Several years ago, a relatively new catalyst for vehicle emission control began showing failure. A team at PNNL found that this seemingly suicidal catalyst wasn’t actually self-destructing but was the victim of an external assailant.
A new technology that offers a novel way to manufacture extrusions with unprecedented improvements in material properties recently received a U.S. patent.
