Flexibility in zeolites: origin, limits, and evaluation

S Ghojavand, E Dib, S Mintova - Chemical Science, 2023 - pubs.rsc.org
Numerous pieces of evidence in the literature suggest that zeolitic materials exhibit
significant intrinsic flexibility as a consequence of the spring-like behavior of Si–O and Al–O …
