Synchronized Structure and Surface Tension Measurement
on Individual Secondary Aerosol Particles by Low-Voltage Transmission
Electron Microscopy
Posted on 2020-06-17 - 12:06
A number of physical and chemical
models have been built to describe
secondary aerosols (SAs) in the atmosphere; however, direct experimental
approaches to simultaneously characterizing the chemical structures
and physical properties on the single-particle level are lacking.
This lack obscures our understanding of SA formation mechanisms and
impedes the development on the accurate prediction and control of
air pollution. Here we obtained clear core–shell structural
information about the aqueous aerosols employing low-voltage transmission
electron microscopy–energy dispersive spectroscopy. The prevalent
10–20% surface tension reduction due to organic matter partitioning
has been unveiled. Further analysis and modeling show that smaller
SAs can yield greater surface tension reduction, while the pronounced
surface tension reduction may enlarge the size of SAs by ≤50%.
Our work paves the way for an unprecedented comprehensive single-particle
study of the global atmospheric SA problem.
