A parameterization for the size- and composition-resolved production fluxes of nascent marine aerosol was developed from prior experimental observations and extrapolated to ambient conditions based on...
Solid state and sub-cooled liquid vapour pressures of cyclic aliphatic dicarboxylic acids
Solid state sub-cooled liquid vapour cyclic aliphatic
2011/2/24
Knudsen Effusion Mass Spectrometry (KEMS) has been used to measure for the first time the solid state vapour pressures of a series of aliphatic cyclic dicarboxylic acids with increasing ring size. Add...
The vapor pressures and activities of dicarboxylic acids reconsidered: the impact of the physical state of the aerosol
dicarboxylic acids the physical state of the aerosol
2010/12/28
We present vapor pressure data of the C2 to C5 dicarboxylic acids deduced from measured evaporation rates of single levitated particles as both, aqueous droplets and solid crystals. The data of aqueou...
