Angstrom‐Scale Triangular Pore in Single‐Layer Hexagonal Boron Nitride Membrane for Molecular Sieving

selectivity of 12.3. Importantly, we show that straightforward mathematical modeling can predict and describe the gas transport properties of the hBN, providing new insights into the molecular transport across atomically thin nanopores. The results gained from this study could significantly advance our understanding of molecular transport across hBN nanopores and may promote the development of hBN membranes to address critical separation issues.
