Superacid H2S2O7, attributed to its S–O–S torsional flexibility for many sulfone groups, is deprotonated by two water molecules, which sets a new record for the fewest number of water molecules to induce dissociation of acids.

Using ab initio density functional theory calculations, we find four-fold degenerate Dirac points protected by two nonsymmorphic symmetries in phosphorene oxide with the inversion symmetry broken.
