Schematic representation of SAT molecules (a), EG molecules (b), macroscopic arrangement of SAT crystals (c), hydrogen bond interactions between water H atoms of SAT and hydroxyl oxygens of EG (d), and macroscopic arrangement for insertion of EG as laminar vesicles (red lines) in SAT matrix (e). The blue, black, yellow and red spheres represent the H, C, O and Na atoms respectively. The hydrogen bond between hydrogen atom of water and hydroxyl atom of EG is represented with doted black lines.
