We have two open PhD positions in the multiphase chemistry group related to the impact of transition metals on 1) dark and photochemical aging of anthropogenic and biogenic SOA and on 2) the photochemical reduction of iodate and nitrate in secondary aerosol. ⬇️

🚀@SiyaoYue from @PSI_LAC is now working on a #ReCLEAN field campaign in the Lagern Forest in Switzerland. With mass spectrometers including EESI, VOCUS and AMS, the scientists are trying to unveil the mysteries of organic nitrogen in the atmosphere 🌍🌿.

The progress of climate change is relentless. However, the injection of particles into the stratosphere could cool the earth. The plan just might work, although have unforeseen consequences. Depletion of the ozone layer is just one of those many risks. https://t.co/HmQZ4kkt5t
