Magnesium Takes ShAPE™

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.

Top Ten Blendstocks for Turbocharged Gasoline Engines

Cover of Co-Optima Report

Bio-blendstocks with the potential to deliver the highest engine efficiency

Report

More efficient engines enabled by better fuels could increase the fuel economy of light duty (LD) vehicles by 10 percent beyond current technology and planned developments. This report identifies top blendstocks that can be derived from biomass and are suitable for further development and commercialization. These blendstocks are best-suited for LD gasoline, boosted spark ignition (BSI) engines. The blendstocks were identified using a fuel property basis using the BSI merit function. The merit function determines potential improvements in engine efficiency, was used to evaluate the performance of candidate bioblendstocks in blends up to 30%. Those that exceeded the efficiency of an E10 premium were included in this list. This report is aimed at biofuel researchers looking to better understand the efficiency implications of biofuels under development, as well as engine researchers who are interested in future biofuels with properties that enable more efficient engine design and operation.

The Co-Optimization of Fuels & Engines (Co-Optima) team includes experts from nine national laboratories: Argonne, Idaho, Lawrence Berkeley, Lawrence Livermore, Los Alamos, Oak Ridge, Pacific Northwest, and Sandia National Laboratories and the National Renewable Energy Laboratory. The team’s expertise includes biofuel development, fuel property testing and characterization, combustion fundamentals, modeling and simulation from atomic scale to engine scale, and analysis.

August 8, 2019
Report

From September 24–26, 2018, Pacific Northwest National Laboratory hosted a System for Terrestrial–Aquatic Research (STAR) workshop to discuss terrestrial–aquatic interface (TAI) research needs. The purpose of this workshop was to continue discussion initiated at the 2016 Department of Energy (DOE)-Biological and Environmental Research (BER) workshop: Research Priorities to Incorporate Terrestrial–Aquatic Interfaces in Earth System Models. Specifically, this workshop focused on terrestrial–aquatic interfaces near the coastline, which have been identified as a major gap in Earth system models (ESMs) and observational networks, important ecosystems that are vulnerable to disturbances from both the land and sea, as well as hubs for human habitation and commerce.

Molecular Mayhem at Root of Battery Breakdown

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.
