Aluminum incorporation into MCM-48 toward the creation of Bronsted acidity

Article Abstract:

The possibilities and limits of aluminum incorporation into the silica framework of a cubic MCM-48 are thoroughly studied by testing four different sources, namely aluminum sulfate, aluminum ethoxide, aluminum isopropoxide and sodium aluminate. Only sodium aluminate are found suitable for the incorporation, as the aluminum sulfate negatively influences the synthesis pH and both alkoxides release alcohol upon their hydrolysis, which will dissolve in the micelles, interfering in the pore arrangements inside the cubic unit cell.

MD simulation of the Na(super +)-phenylalanine complex in water: Competition between cation-pi interaction and aqueous solvation

Article Abstract:

The competition between cation-pi interaction and aqueous solvation for the Na(super +)ion is investigated by molecular dynamics simulations, using the phenylalanine amino acid as the test pi system. It is clear that the Na(super +)-phenylalanine stabilization energy may overcome the interactions with water.

Preferential solvation of Na(super +) in N, N-dimethylformamide-water binary mixture

Article Abstract:

Preferential solvation of Na(super +) by N, N-dimethylformamide (DMF) is observed through mass spectrometry. Once a DMF molecule interacts with Na (super +) it does not form a hydrogen bond.

Solvation, Dimethylformamide
