TL;DR: The SAFARI 2000 field study as mentioned in this paper showed that the aging and reactions of inorganic smoke particles can affect the hygroscopic properties of biomass-burning aerosols and therefore influence their role as cloud condensation nuclei.

TL;DR: Sulfate particles are the main cooling agents among aerosols; it is found that in the remote oceanic atmosphere a significant fraction is aggregated with soot, a material that can diminish the cooling effect of sulfate.

TL;DR: In this article, individual aerosol particles in smoke plumes from biomass fires and in regional hazes in southern Africa were studied using analytical transmission electron microscopy (TEM), which allowed detailed characterization of carbonaceous particle types in smoke and determination of changes in particle properties and concentrations during smoke aging.

TL;DR: Off-axis electron holography in the transmission electron microscope was used to correlate the physical and magnetic microstructure of magnetite nanocrystals in magnetotactic bacteria to find shape anisotropy was found to dominate magnetocrystalline an isotropy in elongated crystals.
