High pressure converts IO3 units to hypercoordinated IO6 in K2Zn(IO3)4.2H2O forming 2D iodate networks, promotes multicenter O-H-O bonds, yields bulk modulus 22(3) GPa, and closes the band gap from 4.2 eV to 3.4 eV at 20 GPa.

Ti-3Al-2.5V undergoes a high-pressure phase transition at 17-19 GPa that rises systematically with Al and V content, while bulk modulus stays constant across Ti-Al-V compositions.
DFT predicts phase transitions in BaSnF4 at 10 GPa and 32 GPa; the first is confirmed experimentally while the second is supported by indirect signatures.
Both (CePr)O2-δ and (CePrLa)O2-δ retain cubic fluorite structure to 30 GPa with a 9-16 GPa anomaly from local distortions and bond bending, while the La-containing compound amorphizes above 22 GPa.
