Characterization of polar organosulfates in secondary organic aerosol from the green leaf volatile 3-Z-hexenal

Evidence is provided that the green leaf volatile 3-Z-hexenal serves as a precursor for biogenic secondary organic aerosol through formation of polar organosulfates (OSs) with molecular weights (MW) 226 and 214. The MW 226 C6-OSs and MW 214 C5M-OSs were chemically elucidated, along with structurally similar MW 212 C5-OS, whose biogenic precursor is likely related to 3-Z-hexenal but still remains unknown. The MW 226, 214 and 212 OSs have a substantial abundance in ambient fine aerosol from K-puszta, Hungary, which is comparable to that of the isoprene-related MW 216 OSs, known to be formed through sulfation of C5-epoxydiols. Using detailed interpretation of negative ion electrospray ionization mass spectral data, the MW 226 and 214 compounds are assigned to sulfate esters of 3,4-dihydroxyhex-5-enoic acid and 3,4-dihydroxypentanoic acid, respectively. One of the four MW 212 compounds present in ambient fine aerosol is attributed to a sulfate ester of 2,3-dihydroxypent-4-enoic acid. The formation of the MW 226 OSs is tentatively explained through photooxidation of 3-Z-hexenal in the gas phase resulting in an alkoxy radical, followed by a rearrangement, and subsequent sulfation of the epoxy group in the particle phase.

NSF, NIST launch new consortium to support advanced manufacturing

three fibers

The National Science Foundation (NSF) and the U.S. Commerce Department’s National Institute of Standards and Technology (NIST) announced today the University of Michigan at Ann Arbor will lead a consortium to identify new, emerging areas of advanced manufacturing that would benefit from shared public-private investment in research and development, education, and training.

The Alliance for Manufacturing Foresight (MForesight) will provide a channel for rapid input from industrial,
