Identifying and quantifying the sources and clarifying the impacts of ultrafine particles (UFP)
in the complicated urban environments are important for particle pollution control and UFP …

Shipping is the main source of anthropogenic particle emissions in large areas of the globe,
influencing climate, air quality, and human health in open seas and coast lines. Here, we …

There is growing concern that exposure to ultrafine particles (UFP, particles with diameter<
100 nm) may have health effects distinct from exposure to fine particulate matter mass (PM …

We performed more than a year of mobile, 1 Hz measurements of lung-deposited surface
area (LDSA, the surface area of 20–400 nm diameter particles, deposited in alveolar regions …

The epidemiological evidence for ultrafine particles (UFP; particles with diameter< 100 nm)
causing chronic health effects independent of fine particulate matter (PM2. 5) mass is …

Measuring the chemical composition of individual atmospheric aerosol particles can provide
direct evidence of their heterogeneous reactions and mixing states in the atmosphere. In this …
