Figure 2

Microphysical properties of BC particles from a Jet-A1 pool-fire. In (a) is a STEM/HAADF image of a typical BC aggregate, while (b) shows the size distribution, in radius, of the monomers (red bars) and its lognormal fit (blue). In (c), a HRTEM image of a monomer is shown illustrating an onion-like structure and (d) presents the C–K edge EEL spectra of a monomer in blue and for graphite in red as a reference.
