The MACE "from scratch" model was used to generate a 1 ns quench for each MOF. This quench (Figure ) involved five stages: a 50 ps equilibration at 300 K, 200 ps ramp, 500 ps at the target temperature, 200 ps quench and then a further 50 ps equilibration at 300 K. This was conducted with a target temperature of 1750 K and 1500 K for CALF-20 and ZIF-8
