作者: Fischer, Michael
The adsorption of water in six structurally different aluminophosphates and their silicoaluminophosphate analogues is investigated using dispersion-corrected density-functional theory calculations. In addition to predicting the interaction energies, the structural changes of the materials upon water adsorption are assessed.

A highly flexible inorganic framework with amphiphilic amine assemblies as templates
An inorganic framework with 24-and-30-ring stacked channels showed extreme flexibility, with a volume change of up to 27.1% under pressure without undergoing a phase transformation.
