Interestingly, when calculating the critical dose based on a relative displacement of the {110} Bragg plane by 1/e (a shrinkage of 37%), the average critical dose for the {110} Bragg plane in ZIF-8 is approximately 33 e -Å -2 , as indicated by the red line. The 37% shrinkage at the critical dose was measured to be 0.41 Å. This suggests that ZIF-8 is considered to maintain its crystallinity if the shrinkage in the {110} Bragg plane is less than 0.4 Å.
