Funding under this call is available for projects dedicated to answering open and pressing questions on the formation of aerosol particles during breathing, speaking, coughing, sneezing, as well as their evaporation kinetics and spreading dynamics in rooms. Furthermore, the call intends to address the efficient removal of aerosol particles from indoor air, the infectiosity of virus-transmitting aerosols and the inactivation of viruses in aerosols via multiphysics approaches (radiation, charging, temperature, etc.) as well as the transport and deposition of aerosol particles in the airways. Proposals and other proposal documents should be submitted via the elan portal by 2 March 2021.
