Refined interacting mesolayer model with variable κ compared to the experiment. c P /c P,liq vs. weight percent nanoparticle. Comparison of the interacting mesolayer model with variable κ to experimental data. The larger solid squares are the Heilmann data (taken at 300 °C) from the previous figure. The smaller symbols including error bars are the data points shown in the bottom panel of Fig. 1 (based on averages in the temperature range from 290 to 335 °C). The lower of the two dashed lines agrees with the dashed line in the previous figure. The upper one, for the larger particles, is obtained by increasing κ min from 0.87 to 0.93
