Monomolecular and multilayers of ferrocene derivatives have been deposited on or bonded
to electrodes and examined by XPS. In many cases the preparation leaves the modified surface
in an oxidized, ferricenium state. Evidence supporting this and possible oxidative mechanisms is
discussed.

This work is concerned with the investigation of galvanoluminescence at the interface
metal-oxide-electrolyte during DC anodization of very pure aluminum foils in boric acid-borax
solution at constant current. The rate of anodic film formation, the quantitative relations
between anode voltage and luminescence intensity as well as the shape of optical emission
spectra at different voltages are obtained for annealed and unannealed Al samples. It is found
that the previous thermal treatment has great influence on anodization and luminescence
processes.

Adsorption in electrochemical systems is discussed by comparing and contrasting it with
adsorption at the gas-metal interface. Some particular problems in the study of solid surfaces
are considered.
