Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Feng Gao
To help meet DOE goals of enabling more fuel-efficient vehicle engine technologies, for the past ~15 years we have been carrying out research programs funded by DOE/Office of Energy Efficiency and Renewable Energy (EERE)/Vehicle Technologies Office...
Lead Institution: University of Toronto
Principal Investigator: Daniel Gregory
This project utilizes atom probe tomography (APT) and transmission electron microscopy (TEM) to investigate microcrystalline masses of pyrite (FeS2) at the nano-scale. These analyses will be completed on samples from different REDOX environments in...
Lead Institution: University of Miami
Principal Investigator: Cassandra Gaston
Aerosols transported from Africa are thought to critically impact the biogeochemical cycling of iron (Fe) and phosphorus (P) in the Amazon and relieve nutrient limitations in this ecosystem. Spectroscopy and microscopy will be used to compare the Fe...
Lead Institution: Washington State University
Principal Investigator: James Harsh
Up to the mid 1900’s, hundreds of thousands of acres across the United States were repeatedly treated with lead-arsenate pesticides to prevent the decimation of orchards by codling moths. Metal arsenate pesticides were eventually phased out starting...
Lead Institution: University of Oklahoma
Principal Investigator: Andrew Elwood Madden
We request rapid-access approval to support the analysis of one each of red, green, and bleached Cutler Formation sedimentary rock samples by Mössbauer spectroscopy by Dr. Ravi Kukkadapu of the EMSL. We request support for instrument time and time...
Lead Institution: Stanford Linear Accelerator Center
Principal Investigator: Kristin Boye
Redox conditions and related switches in microbial metabolic activities exert primary control over the stability of carbon, nutrient, and contaminant stocks in alluvial systems, such as floodplains. This project focuses on a uranium-contaminated...
Lead Institution: Stanford University
Principal Investigator: Scott Fendorf
Although depositional environments such as floodplains are key regulators of ecosystem carbon storage and downstream metal loadings, they are not very well represented in earth system models. Importantly, the fate of organic matter (OM) and redox...
Lead Institution: University of California, Riverside
Principal Investigator: Timothy Lyons
Sulfidic sediments are a key sink for many potentially toxic trace elements in marine settings, with much of these elements ultimately being concentrated into the mineral pyrite. Pyrite can be an effective store for these elements because it is...
Lead Institution: Lawrence Livermore National Laboratory
Principal Investigator: Jennifer Pett-Ridge
In tropical ecosystems, changes in future Earth Systems will likely affect both the amplitude and periodicity of redox oscillations due to predicted increases in temperature and changes in the frequency of precipitation. Our research will measure...
