• the Brunauer–Emmett–Teller (BET) surface adsorption method. The obtained values were in good agreement with those obtained from the exploitation of the SEM images (Table 1). The specific surface area (SSA) of the β-CD samples ground over various periods of time was also extracted from the BET analysis

Contamination has been noted in alloying [26][38] as well as amorphization of hard materials [39], and could cause

This helps in understanding the nonstatistical pattern formation for this surface–adsorbate system and hints toward an inclusion of dispersion attraction as another determining factor for surface adsorption.

• shown that dispersion effects are not only important for the thermodynamic stability of molecule–adsorbate complexes but they also crucially influence the adsorption path. While Pauli repulsion is often discussed as important effect for determining surface adsorption, the attractive part of the van der

This could be attributed to surface adsorption and diffusion into the polymer network. However, it was observed that an activation step in an aqueous solution of

Afterwards, no further moisture uptake was found. In Figure 6, the moisture uptake results of the 6FDA-3,3′-DDS/6FDA-DABA 4:1
