This Project Grant award from the National Science Foundation's (NSF) Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will investigate the photochemical breakdown of marine dissolved organic matter (DOM) and its impact on the global carbon cycle. The $683,778 award, valid from July 2023 to June 2026, will focus on studying the production rates and quantum yields of one and two-carbon photoproducts, such as carbon monoxide, dissolved inorganic carbon, formaldehyde, and...
This $266,730 Project Grant award from the National Science Foundation's Engineering program (CFDA 47.041) supports collaborative research to identify and characterize persistent, oxygen-containing organic compounds (OCOCs) that arise from crude oil and petroleum spills in aquatic environments. The key goals are to: 1) determine how OCOCs form and degrade under different environmental conditions, 2) assess whether native dissolved organic matter affects OCOC molecular signatures, and 3)...
This National Science Foundation (NSF) Project Grant award for $267,000 under the Mathematical and Physical Sciences (CFDA 47.049) program supports computational research and education focused on understanding the interaction of light with ordered assemblies of carbon-based organic molecules. The goal is to develop new design principles for efficient solar energy conversion materials. The research team at Trustees of Boston University will employ first-principles electronic structure theory to...
This $300,785 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a research project to characterize the chemical composition and bioavailability of dissolved organic matter released by marine nitrifying microorganisms. The project aims to determine how this material contributes to carbon cycling in the deep ocean, which may help improve biogeochemical models and inform potential marine carbon dioxide removal activities. The research will...
This $665,899 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to investigate the impact of plastic-derived dissolved organic carbon (PDOC) on the ocean's biological carbon pump. The project will utilize a combination of laboratory experiments, field sampling, and numerical modeling to test the hypothesis that bacteria's consumption of PDOC results in the depletion of key nutrients like nitrogen and...
This Project Grant award of $569,435 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research at Northeastern University to study the impact of plastic-derived dissolved organic carbon (PDOC) on ocean ecosystems. The core objective is to test the hypothesis that bacteria consuming PDOC in surface waters compete with phytoplankton for key nutrients like nitrogen and phosphorus, potentially reducing new production and weakening the biological carbon pump. The...
The Woods Hole Oceanographic Institution (WHOI) will receive $449,385 from the National Science Foundation (NSF) under the Mathematical and Physical Sciences program (CFDA 47.049) to assess the controls of plastic photochemical reactivity in the surface ocean from June 1, 2022 to May 31, 2025. WHOI researchers Collin Ward and Taylor Nelson will study how factors like particle size, plastic formulation, and sunlight wavelength impact the oxidation, chain scission, and dissolved organic production...
Through a $249,997 Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences (CFDA 47.049) program, researchers at the University of New Haven are developing a novel enzyme-responsive polyolefin material as a programmable antifouling coating. The research aims to understand how the properties of these polyolefin surfaces, such as hydrophobicity and texture, impact their ability to prevent and remove microbial adhesion from bacteria and algae commonly...
The National Science Foundation (NSF) Division of Chemistry awarded a $530,000 Project Grant to the University of California, Berkeley under the Mathematical and Physical Sciences program (CFDA 47.049) to develop new computer simulation models for studying light-driven chemical processes. The three-year grant, effective September 1, 2023, will enable the Neuscamman research group to create advanced tools for accurately simulating the movement of electrons and molecules in response to light...
The National Science Foundation (NSF) awarded a $797,203 Project Grant under its Geosciences program (CFDA 47.050) to the University of California Irvine (UC Irvine). The goal of this 3-year project, with an end date of January 2027, is to better understand how photochemical reactions in the solid or liquid phase of organic compounds affect the key properties of organic aerosol in the atmosphere. The research will focus on secondary organic aerosol (SOA) and/or biomass burning organic aerosol...
