Measurements of OH and HO2 yields from the gas phase ozonolysis of isoprene
OH and HO2 yields gas phase ozonolysis isoprene
2010/2/21
The reactions of ozone with alkenes are an important source of hydroxyl (OH) radicals; however, quantification of their importance is hindered by uncertainties in the absolute OH yield. Hydroxyl radic...
Temperature and humidity dependence of secondary organic aerosol yield from the ozonolysis of β-pinene
secondary organic aerosol yield ozonolysis β-pinene
2009/6/16
The temperature dependence of secondary organic aerosol (SOA) formation from ozonolysis of β-pinene was studied in a flow reactor at 263 K–303 K and 1007 hPa under dry and humid conditions (0% and 26%...
Validation of an experimental setup to study atmospheric heterogeneous ozonolysis of semi-volatile organic compounds
atmospheric heterogeneous ozonolysis semi-volatile organic compounds
2009/3/31
There is currently a need for reliable experimental procedures to follow the heterogeneous processing simulating the atmospheric conditions. This work offers an alternative experimental device to stud...
Modelling the formation and composition of secondary organic aerosol from α- and β-pinene ozonolysis using MCM v3
secondary organic aerosol α- and β-pinene ozonolysis MCM v3
2009/3/5
The formation and detailed composition of secondary organic aerosol (SOA) from the gas phase ozonolysis of α- and β-pinene has been simulated using the Master Chemical Mechanism version 3 (MCM v3), co...
Ozonolysis of α-pinene: parameterization of secondary organic aerosol mass fraction
α-pinene secondary organic aerosol mass fraction
2008/12/15
Existing parameterizations tend to underpredict the α-pinene aerosol mass fraction (AMF) or yield by a factor of 2–5 at low organic aerosol concentrations (<5 µg m−3). A wide range of smog...
Particle mass yield in secondary organic aerosol formed by the dark ozonolysis of α-pinene
secondary organic aerosol dark ozonolysis α-pinene
2008/11/4
The yield of particle mass in secondary organic aerosol (SOA) formed by dark ozonolysis was measured for 0.3–22.8 ppbv of reacted α-pinene. Most experiments were conducted using a continuous-flow cham...
The ozonolysis of primary aliphatic amines in fine particles
ozonolysis primary aliphatic amines
2008/10/31
The oxidative processing by ozone of the particulate amines octadecylamine (ODA) and hexadecylamine (HDA) is reported. Ozonolysis of these amines resulted in strong NO2– and NO3– ion signals that incr...
