Novel method of generation of Ca(HCO3)2 and CaCO3 aerosols and first determination of hygroscopic and cloud condensation nuclei activation properties
Ca(HCO3)2 and CaCO3 aerosols hygroscopic and cloud condensation nuclei activation properties
2010/9/21
Atmospheric mineral aerosols contain CaCO3 as a reactive component. A novel method to produce CaCO3 aerosol was developed by spraying Ca(HCO3)2 solution, which was generated from a CaCO3 suspension an...
Kinetics and mechanisms of heterogeneous reaction of NO2 on CaCO3 surfaces under dry and wet conditions
heterogeneous reaction CaCO3 surfaces dry wet
2010/2/1
With increasing NO2 concentration in the troposphere, the importance of NO2 reaction with mineral dust in the atmosphere needs to be evaluated. Until now, little is known about the reaction of NO2 wit...
The heterogeneous chemical kinetics of N2O5 on CaCO3 and other atmospheric mineral dust surrogates
heterogeneous chemical kinetics N2O5 CaCO3 atmospheric mineral dust surrogates
2009/1/6
Uptake experiments of N2O5 on several mineral dust powder samples were carried out under continuous molecular flow conditions at 298±2 K. At [N2O5]0=(4.0±1.0)×1011 cm−3 we have found γss values ...
