The research integrates laboratory experiments, surface characterization, and modeling to quantify how particles attach to sediment grains after multiple encounters. The project will...
- The National Science Foundation awarded a $418,120 Project Grant to the Board of Regents of the University of Nebraska from the Engineering program (CFDA 47.041) for the period of March 1, 2022 through February 28, 2025. The award will support research exploring the transport dynamics and rheology of hydrophobic particles in confined fluid flow. The University of Nebraska will develop computational models and simulations, validated through microfluidic experiments, to better understand how...
- The National Science Foundation Division of Earth Sciences awarded the University of Utah $427,930 on May 1, 2026, under the Geosciences program (CFDA 47.050) to investigate how nanoscale particles including microplastics and pathogens move through soil and groundwater. The research will develop an improved predictive framework by integrating laboratory experiments, surface characterization, and modeling to quantify particle attachment after repeated encounters with sediment grains. The work...
- Federal Grant Award Summary The Board of Regents of the University of Nebraska received a $1,087,895 Project Grant from the National Science Foundation's Division of Emerging Frontiers under the Biological Sciences program (CFDA 47.074), effective September 1, 2025, through August 31, 2028. This research initiative will generate fundamental scientific knowledge regarding the dynamics of carbon and energy fluxes in methanogenic archaea—microorganisms capable of converting low-energy substrates...
- The National Science Foundation Division of Earth Sciences awarded the University of New Mexico $469,493 on October 1, 2026, under the Geosciences program (CFDA 47.050) to investigate soil carbon persistence in dryland floodplains along the Rio Grande in the southwestern United States. The research combines field measurements of groundwater depth and greenhouse gas emissions with laboratory analyses of carbon age and composition in floodplain sediments to develop a mechanistic framework...
- The National Science Foundation Division of Environmental Biology awarded the Board of Regents of the University of Nebraska $1,085,162 on June 1, 2026, under the Biological Sciences program (CFDA 47.074) to investigate how virovory—the consumption of viruses by microorganisms—influences phosphorus and nitrogen bioavailability in lakes. Researchers will combine manipulative experiments, observational data collection, and theoretical modeling to assess the impacts of viral consumption on nutrient...
The National Science Foundation Division of Earth Sciences awarded $496,722 to the Board of Regents of the University of Nebraska on August 1, 2026, under the Geosciences program (CFDA 47.050) to study organic nitrogen dynamics in the vadose zone and their impacts on groundwater quality. The research will characterize pools of organic nitrogen and transformation pathways using field sampling across farms and prairies in Nebraska, high-resolution chemical characterization, and nanoscale infrared spectroscopy. Metagenomic and metatranscriptomic sequencing will identify microbial taxa and gene networks driving nitrate generation. Metabolic and reactive transport models will be parameterized to predict nitrate mobilization under varied hydrologic conditions. The project will train graduate students, undergraduates, and high school students and reach K-12 students, educators, and the public through workshops. The award runs through July 31, 2029, with place of performance in Lincoln, Nebraska. No subawards are planned. The research addresses groundwater contamination from nitrogen that persists in the subsurface in organic forms, slowly converting to nitrate years after fertilizer application, thereby informing farmer and water-manager decisions on fertilizer and land-management practices across the Great Plains.
