Detecting supramolecular organic nanoparticles during heat wave

Renyi Zhang, Yixin Li, Jiayun Zhao, Bianca P. Aridjis-Olivos et autres

New particle formation (NPF) represents a major source of tropospheric fine aerosols. A common viewpoint is that NPF hinges thermodynamically on the volatility of condensing species and is unfavorable at high temperatures. From an intensive field campaign, we observed frequent NPF events …

Controlled particle coating from β -caryophyllene photo-oxidation: An aerosol dynamics modeling–assisted chamber method

Miska Olin, Sining Niu, Hannah E. LeClear, Jiayun Zhao et autres

The Texas A&M Environmental Chamber (TAMEC) was employed to generate secondary organic aerosols (SOA) by oxidizing β-caryophyllene with hydroxyl radicals (•OH) in the presence of ammonium bisulfate seed particles. The TAMEC consists of a 10-m3 fluorinated ethylene propylene (FEP) bag in a …

Constraining Gas Phase Yields and Reactive Uptake Coefficients of Oxidation Products from the Hydroxyl Radical-Isoprene Reaction onto Acidic Particles by Vocus Ammonia-Adduct Chemical Ionization Mass Spectrometry (Vocus NH4+ CIMS)

Jiayun Zhao, Sahir Gagan, Molly P. Frauenheim, Sining Niu et autres

Isoprene, the most abundant nonmethane volatile organic compound in the atmosphere, undergoes photochemical reactions with hydroxyl radical ( • OH), a major sink for isoprene, leading to the formation of secondary organic aerosol (SOA). Using a Vocus Chemical Ionization Mass Spectrometer with …

Maternal exposure to ultrafine particles enhances influenza infection during pregnancy

Nicholas L. Drury, Toriq Mustapha, Ross A. Shore, Jiayun Zhao et autres

BACKGROUND: Interactions between air pollution and infectious agents are increasingly recognized and critical to identify, especially to protect vulnerable populations. Pregnancy represents a vulnerable period for influenza infection and air pollution exposure, yet interactions during pregnancy remain unclear. Maternal exposure to ultrafine …

In Utero Ultrafine Particulate Exposure Yields Sex- and Dose-Specific Responses to Neonatal Respiratory Syncytial Virus Infection

Carmen H. Lau, Jonathan C. Behlen, Alexandra N. Myers, Yixin Li et autres

High Resolution Image Download MS PowerPoint Slide Exposure to particulate matter (PM) is associated with lower respiratory tract infections. The role of ultrafine particles (UFPs, ≤0.1 μm) in respiratory disease is not fully elucidated, especially in models of immunologically immature populations. To …
