TIGHT-BINDING STUDIES FOR ELECTROACTIVE ORGANIC POLYMERS

Le Journal de Physique Colloques, 1983
A tight-binding model is presented which accurately reproduces the valence band structure of both graphite and diamond. The model is used to calculate the band structure and density of states of polyacetylene, and agreement with experimental XPS results is seen to be excellent.

Marine aerobic biofilm as biocathode catalyst [PDF]

, 2010
Stainless steel electrodes were immersed in open seawater and polarized for some days at − 200 mV vs. Ag/AgCl. The current increase indicated the formation of biofilms that catalysed the electrochemical reduction of oxygen.
