Lewis structures performance comparison

In Figure 4, the performance comparison on non-nanoscience and materials nanoscience and materials items for pre-engineering chemistry students, it can be seen that in both the areas of spectroscopy and Lewis structure, the engineering stndents have a higher performance when the format of the item inclndes reference to either nanoscience or special materials. This observation is very interesting, becanse nnlike the areas of intermolecular forces and band theory, neither of these concepts were known to be taught in the context of... 

A pure silica MCM-48 is activated by a controlled dispersion of A1 onto the substrate surface performed by anchoring of the Al(acac)3 complex onto the surface silanols. A calcination step removes the organic ligands. The characteristics of the final structure are evaluated by comparison with A1 incorporated MCM-48. The type and concentration of Lewis/Br0nsted acid sites is investigated by the adsorption of NH3 and CD3CN.
