Organic peroxides (POs) are organic molecules with one or more peroxide (− O–O−)
functional groups. POs are commonly regarded as chemically labile termination products …

Influenza incidence and seasonality, along with virus survival and transmission, appear to
depend at least partly on humidity, and recent studies have suggested that absolute …

Atmospheric aerosols are complex mixtures of different chemical species, and individual
particles exist in many different shapes and morphologies. Together, these characteristics …

Atmospheric soot and organic particles from fossil fuel combustion and biomass burning
modify Earth's climate through their interactions with solar radiation and through …

Secondary organic aerosols (SOA) are a large source of uncertainty in our current
understanding of climate change and air pollution. The phase state of SOA is important for …

The detailed physico-chemical characteristics of respiratory droplets in ambient air, where
they are subject to evaporation, are poorly understood. Changes in the concentration and …
