Onishi-Ice_interface-Micrograph (IMAGE) Kobe University Caption While ice without surrounding liquid (A) features so-called “frost pillars” about 20 nanometers tall, in 1-octanol antifreeze (B) the ice is perfectly flat with occasional steps only one molecular layer high. In different liquids (C: 1-hexanol. D: 1-butanol) with similar properties, the ice surface looks different in each case, underscoring the importance of directly measuring the interface.
