Relation between CHF and surface characteristics. (a) CHF of pure water vs. contact angle of a water droplet on nanoparticle-deposited surfaces. SEM pictures (b) and maximum capillary wicking height of pure water (c) for surfaces boiled in 10-3% (A) and 10-1% (B) water-TiO2 nanofluids, with the same contact angles of ~20° [60].
