Heterogeneous conversion of NO₂ and NO on HNO₃ treated soot surfaces: atmospheric implications [PDF]

Atmospheric Chemistry and Physics, 2005
In the present study, the heterogeneous conversion of nitrogen oxide (NO) and nitrogen dioxide (NO2) was studied at atmospheric humidity levels on flame soot surfaces treated with gaseous nitric acid (HNO3).

Soot Formation in Spray Flames

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1980
Soot and oxygen concentrations, and temperature distribution in kerosene spray flames were measured to study the relation between soot formation and characteristics of spray flames. The distributions of soot and oxygen concentrations have an inverse tendency to each other. The maximum soot concentration and the minimum oxygen concentration are observed

Soot aerosols from commercial aviation engines are poor ice-nucleating particles at cirrus cloud temperatures [PDF]

Atmospheric Chemistry and Physics
Ice-nucleating particles catalyze ice formation in clouds, affecting climate through radiative forcing from aerosol–cloud interactions. Aviation directly emits particles into the upper troposphere where ice formation conditions are favorable.

Atomic-scale insights into laser-induced patterned graphitization of combustion-derived soot

Chemical Physics Impact
Soot has long been recognized as a representative combustion by-product and a major contributor to environmental pollution. Direct utilization of soot as a functional carbon material is fundamentally limited by its high defect density and intrinsically ...
