The pore-load modulus of ordered nanoporous materials with surface effects

The pore-load modulus of ordered nanoporous materials with surface effects

Gas and liquid adsorption-induced deformation of ordered porous materials is an important physical phenomenon with a wide range of applications. In general, the deformation can be characterized by the pore-load modulus and, when the pore size reduces to nanoscale, it is affected by surface effects a...
