Water density in the electric double layer at the insulator/electrolyte solution interface

Article Abstract:

The spatial structure of the thick transition region between n-hexane and a colloidal solution of silica particles by X-ray reflectivity and grazing incidence small-scattering was studied. The X-ray scattering data revealed that the average density of water in the field of the electrical double layer at the hexane-silica sol interface is the same as or only few percent higher than, its density under normal conditions.

Inner-shell excitation spectroscopy and X-ray photoemission electron microscopy of adhesion promoters

Article Abstract:

The C 1s, Si 2p, Si 2s and O 1s inner-shell excitation spectra of vinyltriethoxysilane, trimethylethoxysilane and vinyltricetoxysilane is recorded by electron energy loss spectroscopy under scattering conditions dominated by electric dipole transitions. The use of the measurements in assisting chemistry studies of adhesion promoters for electronic applications is discussed.
