Electrochemical study of interfacial composite nanostructures: Polyelectrolyte/gold nanoparticle multilayers assembled on phospholipid/dextran sulfate monolayers at a liquid-liquid interface

Article Abstract:

The study for the interfacial capacitance of the composite multilayers is conducted and it is shown that the decrease of the overall capacitance with the number of layers is due to the increasing thickness as well as to the decreasing partition coefficients of the supporting electrolytes in the hydrocarbon region and the multilayer. These nanocomposites behave similarly to polyelectrolyte multilayers, with the outmost layer determining the alternating sign of the outer surface charge density.

Radiolytic hydrogen yields in aqueous suspensions of gold particles

Article Abstract:

The effect of high concentrations of large gold particles on the yields of molecular hydrogen, G(H2), produced in the radiolysis of several aqueous solutions is investigated. The results show that the redox catalysis does not depend on the size of the particles when their size exceeds a few nanometers.
