1. 6. Volatility and number measurement of diesel engine exhaust particles

   Författare :Hanna Bernemyr; Hans-Erik Ångström; Nigel Clark; KTH; []
   Nyckelord :particle emissions; measuring methods; particle number measurements; dilution; rotating disc diluter; v-TDMA; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Today, emission legislations for engine exhaust particles are mass based. The engines of today are low-emitting with respect to particle mass, with the emissions approaching the detection limit of the current measurement method. This calls for new and improved measurement methods. LÄS MER

3. 7. Physical properties and processes of secondary organic aerosol and its constituents

   Författare :Kent Salo; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SOA; ageing; VOC; atmosphere; volatility; VTDMA; monoterpenes; ageing;

   Sammanfattning : Atmospheric aerosol particles are involved in several important processes including the formation of clouds and precipitation. A considerable fraction of the ambient aerosol mass consists of organic compounds of both primary and secondary origin. LÄS MER
