For dodecane droplets (Fig. 3c) t decreases from around 25◦
(no particles and 0.5% w/w particle concentration) to 7◦ at 1% w/w
particle concentration. A very slight increase is recorded at 3% w/w
(t = 9◦) which is the last measurement that could be reported, as
dodecane was absorbed by coatings, which were prepared using 4
and 5% w/w nanoparticles.
