Proximal adsorption of cationic surfactant on silica at equilibrium

Article Abstract:

The pressure between the surfaces in these concentrated solutions is well described by an osmotic interaction with the concentration derived from surface excess and a constant osmotic coefficient. Changes in adsorption have been used to make qualitative arguments explaining the deviation of measured interaction energies below the constant potential boundary condition for double-layer forces and quantitative explanations for depletion and oscillatory forces.

"Side chain" modification of MCM-41 silica through the exchange of the surfactant template with charged functionalized organosiloxanes: an efficient route to valuable reconstructed

Article Abstract:

Experiments were conducted to obtain the synthesis of 'side chain' functionalized MCM-41 inorganic-organic hybrids through the exchange method of the template with the cationic organosiloxanes. The results show that the derivative obtained retained the hexagonal symmetry of the original MCM-41 material and the final solids exhibit rather small BET surface areas and microporosity.

A modified Poisson-Boltzmann model inducing charge regulation for the adsorption of ionizable polyelectrolytes to charged interfaces, applied to lysozyme adsorption of silica

Article Abstract:

The equilibrium adsorption of polyelectrolytes with multiple types of ionizable groups is described using a modified Poisson-Boltzmann equation including charge regulation of both the polymer and the interface. The influence of pH and ionic strength on the equilibrium adsorption of lysozyme on silica was discussed using a one-dimensional mean-field model.
