Controlled ice formation on sub 10 nm condensation nuclei has been observed for the first time under mesospheric conditions at the Atmospheric Nanoscience group. The laboratory experiment took place in a cooled linear radiofrequency ion trap in an ice-oversaturated environment, where free iron-oxide particles with growing ice shells could be stored for several seconds. In the near future systematic investigations of ice nucleation probabilities and growth rates of mesospheric relevant materials are planned.
