Nanopore engineering holds great promise for energy, DNA sequencing, and quantum information technologies, but pore evolution, particularly in presumably stable materials such as boron nitride, is largely unexplored. Here, the authors use high-resolution transmission electron microscopy to show that different nanopores formed in mono- and multi-layer hexagonal boron nitride are stable in vacuum but undergo dramatic changes in air.
