Extended Data Fig. 6 | Determination of growth rate using the
appearance-time method. a, Logarithmic interpolated time-dependent
growth profiles for particles with diameters of 100 nm, 150 nm and 200 nm.
Three appearance times, when particle number concentrations reached 10%,
50%, and 90% of their maximum, are labelled with different symbols for the
three different diameters. b, Growth-rate calculation for a rapid growth event
(as in Fig. 2 ) above the activation diameter. The growth rates, in nm h−1, that we
report here are the slopes of linear fits to the 50% (among 10%, 50% and 90%)
appearance times calculated from all sizes above the activation diameter (the
slope of the solid black line and the black circles in b).
