Overwhelming evidence exists that exposure to outdoor fine particulate matter (PM2.5) is associated with a range of short-term and chronic health impacts, including asthma exacerbation, acute and ...

A new study published in National Science Review examines China's trends in primary particulate matter (PM) emissions from 1960 to 2019, revealing significant transformations in PM size fractions and ...

Here we demonstrate a low-profile and cavity-free size spectrometer for probing fine and ultrafine particulate matter by using the enhanced particle-perturbed scattering in strong optical ...
