Laboratory study on new particle formation from the reaction OH + SO2: influence of experimental conditions, H2O vapour, NH3 and the amine tert-butylamine on the overall process
Laboratory study new particle formation the reaction OH + SO2 H2O vapour NH3 the amine tert-butylamine the overall process
2010/8/16
Nucleation experiments starting from the reaction of OH radicals with SO2 have been performed in the IfT-LFT flow tube under atmospheric conditions at 293±0.5 K for a relative humidity of 13–61%. The ...

2010/2/21
Results obtained by a laboratory flux measurement system (LFMS) focused on investigating the kinetics of the mercury emission flux (MEF) from contaminated soils of the Idrija Hg-mine region, Slovenia ...
The effects of experimental uncertainty in parameterizing air-sea gas exchange using tracer experiment data
parameterizing air-sea gas tracer
2009/3/12
It is not practical to measure air-sea gas fluxes in the open ocean for all conditions and areas of interest. Therefore, in many cases fluxes are estimated from measurements of air-phase and water-pha...

homogeneous freezing sulphuric acid particles aerosol chamber AIDA
2009/3/10
The homogeneous freezing of supercooled H2SO4/H2O solution droplets was investigated in the aerosol chamber AIDA (Aerosol Interactions and Dynamics in the Atmosphere) of Forschungszentrum Karlsruhe. 2...
Ozone decomposition on Saharan dust: an experimental investigation
Ozone decomposition Saharan dust experimental investigation
2009/3/10
The heterogeneous reaction between O3 and authentic Saharan dust surfaces was investigated in a Knudsen reactor at approx 296 K. O3 was destroyed on the dust surface and O2 was formed with conversion ...
