Finally, the mechanical properties of this large library of hypothetical zeolites can be leveraged with the calculated porosity features to discover relationships which were pre- viously difficult to recognise owing to the relatively few zeolites for which elastic moduli have been calculated. There have been a number of studies examining porosity of large databases however, the mechanical properties of the materials is often neglected despite providing valued insight to the inherent stability of the structure. Illustrated in Figure is the accessible pore volume (for a probe size equivalent to He) plotted against G.
