27. For the case of copper, we also observe the presence oxidized sulfur, which is initially present in a similar amount as copper. But the signal corresponding to sulfur decreases with time, which is a known effect for sulfates under XPS probe.

29. Similarly nylon, which contains polar groups, was reported to be spontaneously charged whereas polyethylene, which does not contain polar groups, is not charged; see Ref. [11].

31. The difference in the ability of electrets to affect ice nucleation may be due to two reasons. Firstly, the charge density on electrets is about two magnitudes lower than what pyroelectrics can deliver. Secondly, upon heating and cooling pyroelectrics generate surface charge continuously, as long as the temperature continues changing, whereas the charge of electrets is neutralized almost immediately after contact with water.
