Aerosols are responsible for phenomena, that tangent our everyday life on multiple layers spanning from atmospheric cloud formation to medical applications. The smallest aerosol particles emerge from gas-to-particle conversion and nucleation/condensation processes – mechanisms still not fully understood, yet of high importance in atmospheric sciences and industrial demands (semi-conductor production, health industry, ..)

Newly developed instrumentation, contributing to the expansion of scientific frontiers concerning sub-10-nm particle dynamics, is to be characterized and tuned, to ensure its functionality and its capability of matching the prerequisites dictated by ultra fine particle measurements.

Hence, within the scope of my doctoral studies my focus lay on improving the knowledge on formation pathways and dynamics of ultrafine particles. To achieve this goal l am conducting laboratory- and outdoor-measurements. From the results derived by these measures it will be possible to develop further insight into mechanisms governing condensational particle growth, derive parameter dependencies and provide landmarks for improving state-of-the-art particle size enhancers.

Lastly, the gathered information about device characteristics aids in the efforts to further develop size magnifying systems. My doctoral project is conducted in collaboration with Airmodus Oy.
