This fellowship opportunity, offered through the NRC Research Associateship Programs at the National Institute of Standards and Technology (NIST), focuses on advancing the understanding of secondary organic aerosol (SOA) chemistry. SOA formation from atmospheric volatile organic compounds (VOC) is a critical but uncertain factor in estimating global radiative forcing. The research aims to probe the chemical mechanisms and kinetics of VOC oxidation reactions that produce condensable aerosol material.
Experimental work involves initiating reactions of photolabile precursors via ultraviolet photolysis within a laminar flow cell. A moveable probe samples the evolving particle distribution, allowing time-dependent monitoring of particle and gas-phase properties. Researchers may apply a variety of diagnostic techniques including tandem differential mobility analysis (tDMA), high-performance liquid chromatography (HPLC), tandem mass spectrometry (MS), gas chromatography-mass spectrometry (GC-MS), UV-VIS, and Fourier-transform infrared (FTIR) spectroscopy.
Proposals are encouraged to explore novel reaction schemes or innovative analytical strategies to deepen the understanding of SOA formation chemistry.
