Figure 8
Typical USAXS from soot particles in a diffusion flame (acetylene, 90 ml min−1, volume fraction φ ≃ 10−6). The absolute scattering intensity [I(q)] (inset) determined by USAXS is combined with pinhole SAXS data at larger q as indicated. The inset also shows a fit to the measured data by means of the unified scattering model for mass-fractal aggregates using three structural levels (see text for more details). |
