Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Vijayakumar Murugesan
The detailed investigation of advanced battery electrolyte solution structure and dynamics is critical to the ongoing development and capability expansion of alternative battery technologies for grid storage. Fundamental studies inform the design of...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Kevin Rosso
We propose to conduct the photodegradation on two dissolved organic matter (DOM) samples in the presence of hematite nanoparticles under solar light for the first time. This treatment will produce reactive oxygen species to abiotically oxidize...
Lead Institution: University of Wyoming
Principal Investigator: Mengqiang Zhu
Soil organic matter (SOM) is the largest organic carbon (C) pool in terrestrial ecosystems and its formation and stability strongly affect global carbon cycling and climate change. The widely accepted Microbial Efficiency-Matrix Stabilization (MEMS...
Lead Institution: Oregon State University
Principal Investigator: Kate Lajtha
Limited knowledge of the molecular mechanisms behind soil organic matter (SOM) stabilization and destabilization processes impedes improving models of earth systems and global carbon dynamics, as well as our ability to understand important linkages...
Lead Institution: Cornell University
Principal Investigator: Carmen Martinez
Soil organic matter (SOM) is the largest reservoir of carbon (C) and nutrients, especially nitrogen (N), in terrestrial ecosystems. SOM is found throughout soil profiles, with content typically decreasing from surface to bedrock. Current theory...
Lead Institution: University of Vermont
Principal Investigator: Aimee Classen
Soil carbon (C) feedbacks to the atmosphere remain one of the greatest areas of uncertainty in future climate predictions, largely due to an inadequate representation of three key factors in ecosystem models -- soil organic matter (SOM) chemistry,...
Lead Institution: Environmental Molecular Sciences Laboratory
Principal Investigator: Kirsten Hofmockel
Soil organic matter (SOM) is the largest active carbon reservoir in the terrestrial environment and significantly influences soil fertility, water quality, global C cycling and associated feedbacks to Earth's climate system. It is increasingly...
Lead Institution: University of Georgia
Principal Investigator: Rebecca Abney
Prescribed burning has exponentially increased in the United States over the past five years due to growing research into its use for land management and recent changes in legislation. While the impacts of wildfire on soil organic matter (SOM)...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Jason McDermott
The goal of this project is to attain a systems level understanding of the soil microbiome and its phenotypic response to changing moisture through a tractable, spatially explicit examination of the molecular and ecological interactions occurring...
Lead Institution: University of North Carolina at Chapel Hill
Principal Investigator: Elizabeth Shank
Soil microbial processes exert a major influence on many of our planet's ecosystems, yet our ability to directly observe the enzymatic and metabolic activities of microbes within soil is currently critically limited. This in part due to the...
