Graphical Abstract
It's what's inside that counts! Nanoporous materials with large internal surface area have been extensively employed as host materials in nanotechnology. Since the lower co-ordination of atoms of nanoporous structures can lead to the redistribution of electronic charge and change the cohesive energy of single atoms in the matrix (see image), the mechanical responses differ from those of atoms in the bulk counterpart.
