Crystal porosity and the burden of proof.
The study of porosity in the context of crystal engineering is rapidly growing in intensity. However, claims of porosity are often highly subjective and use of the term "porous" is susceptible to abuse. This contribution discusses some of the criteria to be considered when stating that a particular crystal structure is porous.
