“…That SHG is generated only in the areas close to the crystal edges is caused by the interconnected two-dimensional pore system: the dipole chains are increasingly disrupted due to diffusion of PNA from one pore to an adjacent pore as PNA diffuses deeper into the crystal. In earlier studies, XRD and NMR studies concluded for PNA in ZSM-5 either an overall polar ordering or a nonpolar ordering [63][64][65][66]. The results shown here in fact show that polar and nonpolar ordering of PNA both occur inside the same crystal.…”

“…13 Van Koningsveld and Jansen reported the deformation of H-ZSM-5 zeolite upon adsorption of naphthalene 14 and p-nitroaniline. 16 Nair and Tsapatsis 20 also reported noticeable deformation of the silicalite lattice after adsorption of o-xylene and m-xylene. Expansion of zeolites of the natrolite family in the course of water adsorption was observed through in situ XRD experiments.…”

When a solid surface accommodates guest molecules, they induce noticeable stresses to the surface and cause its strain. Nanoporous materials have high surface area and, therefore, are very sensitive to this effect called adsorption-induced deformation. In recent years, there has been significant progress in both experimental and theoretical studies of this phenomenon, driven by the development of new materials as well as advanced experimental and modeling techniques. Also, adsorption-induced deformation has been found to manifest in numerous natural and engineering processes, e.g., drying of concrete, water-actuated movement of non-living plant tissues, change of permeation of zeolite membranes, swelling of coal and shale, etc. In this review, we summarize the most recent experimental and theoretical findings on adsorption-induced deformation and present the state-of-the-art picture of thermodynamic and mechanical aspects of this phenomenon. We also reflect on the existing challenges related both to the fundamental understanding of this phenomenon and to selected applications, e.g., in sensing and actuation, and in natural gas recovery and geological CO2 sequestration.

“…However, XRD measurements have shown that some adsorbed molecules change the crystal unit cell [31][32][33]. We have shown recently that n-hexane 0376 adsorption swells MFI crystals, and this expansion shrinks the size of defects in MFI membranes [34][35][36][37].…”
