    • 2 solvation shell is substituted by the silanol groups. The solvent molecules enable repetition of this cycle: Entropy change provides the driving force for the anions to enter the mesopores by way of substituting for loosely held solvent molecules, whereas the drop in enthalpy directs the ordering of the sorbed clusters onto the pore walls.

    • c = 0.95 mm, giving an interpretable point resolution of -0.185 nm. STEM experiments were conducted using a field emission dedicated microscope (VG HB501). MCM-41 samples were prepared by crushing the particles between two glass slides and spreading them on a holey carbon film supported on a Cu grid. The samples were briefly heated under a tungsten filament light bulb in air before transfer into the specimen chamber. The images were recorded at magnifications of 24,000x to 49,000x.

    • Although STEM images display less contrast than the corresponding HRTEM images, STEM enables shorter exposure times, hence electron-beam damage is reduced.
