In the case of silica-alumina, the sites are ascribed to the presence of trivalent aluminum ions, Al3+, in a matrix of quadrivalent silicon ions, Si4+, which gives rise to charge differences in the neighbourhood of the aluminum ions.
The growth of ultra thin films on the surface of an oxide material can be used to introduce a dipole moment at that surface due to charge differences.
From the presented results, it can be concluded that CE is especially suitable for the separation of protein modifications leading to charge differences.
Slight particle size and surface charge differences and different cell lines had significant implications in the cellular uptake of NPs, and various mechanisms were involved in the uptake process.
These mobility alterations may have resulted from charge differences, conformational changes of tetramers, or even different number of subunits in the differently migrating fractions.
Electrophoresis takes advantage of these charge differences to effect a separation.
The charge differences may impact both PK and PD.
Under this setup, multiple samples can be separated on the same gel by their charge differences.
This large atomic charge differences between structures (b) and (d) is due to the presence of TS-c (hydride shift).
Calculated binding energies, charge differences of the adsorbed chromate anions, and the optimized shortest internuclear distances for studied adsorption configurations are presented in Table 1.
