TL;DR: In this article, the authors focus on the identification of the main organic aerosol sources and define a standardized methodology to perform source apportionment using positive matrix factorization (PMF) with the multilinear engine (ME-2) on Aerodyne aerosol mass spectrometer (AMS) data.
Journal ArticleDOI
Ubiquity of organic nitrates from nighttime chemistry in the European submicron aerosol

TL;DR: In this article, particle phase measurements performed at a suburban site in the Netherlands showed that organic nitrates contribute substantially to particulate nitrate and organic mass, implying a substantial potential of PM reduction by NOx emission control.
Journal ArticleDOI
Trace Metals in Soot and PM2.5 from Heavy-Fuel-Oil Combustion in a Marine Engine.
Joel C. Corbin,Amewu A. Mensah,Simone M. Pieber,J. Orasche,B. Michalke,Marco Zanatta,Hendryk Czech,Dario Massabò,F. Buatier de Mongeot,Carlo Mennucci,I. El Haddad,Nivedita K. Kumar,Benjamin Stengel,Y. Huang,Ralf Zimmermann,André S. H. Prévôt,Martin Gysel +16 more
TL;DR: It is found that <3% of total PM2.5 metals was associated with soot particles, which may still be sufficient to influence in-cylinder soot burnout rates, and an enrichment of V in soot due to its lower nucleation/condensation temperature is observed.
Journal ArticleDOI
SOA from limonene: role of NO 3 in its generation and degradation
Juliane L. Fry,Juliane L. Fry,Astrid Kiendler-Scharr,A. W. Rollins,Theo Brauers,Steven S. Brown,H.-P. Dorn,William P. Dubé,Hendrik Fuchs,Hendrik Fuchs,Amewu A. Mensah,Amewu A. Mensah,Franz Rohrer,Ralf Tillmann,Andreas Wahner,Paul J. Wooldridge,Ronald C. Cohen +16 more
TL;DR: In this paper, the formation of organic nitrates and secondary organic aerosol (SOA) were monitored during the NO 3 + limonene reaction in the atmosphere simulation chamber SAPHIR at Research Center Julich.
Journal ArticleDOI
Measurement of aircraft engine non-volatile PM emissions: results of the Aviation-Particle Regulatory Instrumentation Demonstration Experiment (A-PRIDE) 4 campaign
Prem Lobo,Lukas Durdina,Gregory J. Smallwood,Theodor Rindlisbacher,Frithjof Siegerist,Elizabeth A. Black,Zhenhong Yu,Amewu A. Mensah,Donald E. Hagen,Richard C. Miake-Lye,Kevin A. Thomson,Benjamin T. Brem,Joel C. Corbin,Manuel Abegglen,Berko Sierau,Philip D. Whitefield,Jing Wang +16 more
TL;DR: In this paper, the authors report the first data on aircraft engine non-volatile particulate matter (NVPM) number-and mass-based emissions using standardized systems, and compare two compliant sampling and measurement systems operated by Missouri University of Science and Technology (Missouri S&T) and Empa.
