Project Grant R42ES026532

This Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $214,924 to Aerodyne Research Inc. to develop a field-deployable Oxidation Flow Reactor and conduct associated laboratory and field studies. The Reactor will be used to better understand nighttime chemistry in the atmosphere, specifically the relative contributions of hydroxyl and nitrate radicals to the formation of oxidized...

This three-year, $749,453 National Science Foundation project grant funds research at the California Institute of Technology into the atmospheric oxidation of volatile chemical products and their impact on air quality. Led by Drs. Paul Wennberg, Brian Stoltz, and John Crounse, the research team will study the chemical reactions of oxygenated hydrocarbons as they degrade in the atmosphere. A major focus is whether radical autoxidation pathways produce highly oxygenated compounds that contribute...

This $788,406 project grant from the National Institutes of Health National Institute of Allergy and Infectious Diseases, under the Allergy and Infectious Diseases Research program (CFDA 93.855), will fund the development of a sensitive, direct reading bioaerosol detection platform to quantify airborne pathogens such as SARS-CoV-2. Aerosol Devices Inc. will integrate their gentle condensation-growth capture sampler, which concentrates intact, viable virus particles into a small liquid volume...

The Department of Energy's Office of Science awarded Aerosol Dynamics Inc., a small research and development company, a $242,869 Project Grant to measure atmospheric sulfuric acid concentration using a water-based condensation particle counter. The grant was awarded on February 12, 2024 under the Office of Science Financial Assistance Program (CFDA 81.049), which funds fundamental research and development projects to advance scientific understanding and technologies aligned with DOE's...

This National Science Foundation project grant of $297,176 supports the initial development of the Molecular Isomer Resolving Aerosol Collector and Analyzer (MIRACA) by the Desert Research Institute from April 2023 through March 2025. The MIRACA aims to improve measurement of the chemical composition of ambient organic aerosols with time resolution of 10 minutes to one hour. It will collect and analyze both particulate and gaseous components of organic aerosol without thermal decomposition...

This National Science Foundation project grant award of $334,376 will fund the development of a new field-deployable Oxidation Flow Reactor tool and its use in laboratory and field studies to advance understanding of nighttime nitrogen chemistry in the atmosphere. Specifically, the collaborators will build an Oxidation Flow Reactor to provide new insights into nitrate radical-initiated atmospheric oxidative aging processes and the relative contributions of hydroxyl and nitrate radicals to the...

This Project Grant, awarded by the National Science Foundation's (NSF) Mathematical and Physical Sciences Federal Grant Program (CFDA 47.049), provides $500,000.00 in funding to the University of California, Los Angeles (UCLA) to investigate the gas-phase reaction pathways of peroxy radicals (RO2) and their implications for secondary organic aerosol formation in the Earth's atmosphere. The principal investigator, Professor Victoria Barber, and her students will use sophisticated analytical...

This three-year Project Grant from the National Science Foundation's Division of Chemistry, totaling $413,144, supports collaborative research between Columbia University and Utah State University on surface-specific aerosol chemistry. The researchers will apply unique laboratory methods—surface-specific sum frequency generation and highly-sensitive hyperRaman scattering—together with gas-particle chemical kinetics studies, to characterize processes unique to aerosol surfaces. They will...

The Department of Energy Office of Science awarded Aerodyne Research Inc. a $249,999 Project Grant under the Office of Science Financial Assistance Program (CFDA 81.049) to support the TOTAL REACTIVE NITROGEN FLUX MONITOR project from February 14, 2022 to November 13, 2022. The Office of Science's mission is to deliver scientific discoveries and tools that transform understanding of nature and advance U.S. energy security and economic competitiveness. This award will allow Aerodyne Research to...

This National Science Foundation Division of Chemistry project grant award of $541,660 provides funding from July 1, 2022 to June 30, 2025 for research into reactive oxygen species in biomass burning particles. Professors Manabu Shiraiwa and Sergey Nizkorodov at the University of California, Irvine will investigate the dependence of ROS formation on the chemical composition and photochemical aging of biomass burning organic aerosol (BBOA) particles. Electron paramagnetic resonance spectroscopy...
