Detailed heterogeneous chemistry in an urban plume box model: reversible co-adsorption of O3, NO2, and H2O on soot coated with benzo[a]pyrene
Detailed heterogeneous chemistry urban plume box model NO2 H2O
2009/10/9
This study assesses in detail the effects of heterogeneous chemistry on the particle surface and gas-phase composition by modeling the reversible co-adsorption of O3, NO2, and H2O on soot coated with ...
Heterogeneous conversion of NO2 and NO on HNO3 treated soot surfaces: atmospheric implications
NO2 NO HNO3 soot surfaces atmospheric implications
2009/1/23
For the treatment of soot by pure HNO3 only reversible uptake with a surface coverage of ~1-2x1014 HNO3 cm-2 was observed for HNO3 mixing ratios in the range 250-800ppbv. Only for higher HNO3 mixing r...
Processing of soot in an urban environment: case study from the Mexico City Metropolitan Area
Processing of soot urban environment Mexico City Metropolitan Area

Chemical composition, size, and mixing state of atmospheric particles are critical in determining their effects on the environment. There is growing evidence that soot aerosols play a particularly imp...
Insights into the role of soot aerosols in cirrus cloud formation
soot aerosols cirrus cloud formation
2008/12/17
Cirrus cloud formation is believed to be dominated by homogeneous freezing of supercooled liquid aerosols in many instances. Heterogeneous ice nuclei such as mineral dust, metallic, and soot particles...
