AI Summary

Scientists have documented a nanometer‑scale vapor barrier that forms when ice contacts an extremely hot surface, preventing immediate melting. The barrier, only a few billionths of a meter thick, appears within nanoseconds, allowing the ice to glide similarly to the Leidenfrost effect observed with liquid water. This rapid formation of vapor at such a tiny scale reveals a new aspect of heat transfer between solid ice and high‑temperature materials.
