[EN] Understanding the optical and electronic excitations in conjugated polymers, their delocalization, and dynamics is of paramount importance for improving the performance of optoelectronic devices. The structure of a ...
The conducting self-doping copolymer poly(aniline-co-ABA) preserves its redox activity at pH values as high as 7. This observation was the starting point to synthesize an organic inorganic hybrid composite able to ...
Composite materials made of porous SiO2 matrices filled with single-walled carbon nanotubes (SWCNTs) were deposited on electrodes by an electroassisted deposition method. The synthesized materials were characterized by ...
Porous, electrically insulating SiO2 layers containing polystyrene sulfonate (PSS) were deposited on glassy carbon electrodes by an electrochemically assisted deposition method. The obtained material was characterized by ...
The effect of the electrochemical treatment (potentiostatic treatment in a filter-press electrochemical cell) on the adsorption capacity of an activated carbon cloth (ACC) was analyzed in relation with the removal of ...
[EN] The present work deals with the direct electrochemistry of cytochrome c (cyt c) encapsulated within a methyl-modified silica film prepared by the sol-gel method. It was observed that the voltammetric currents of the ...
The electroassisted encapsulation of Single-Walled Carbon Nanotubes was performed into silica matrices (SWCNT@SiO2). This material was used as the host for the potentiostatic growth of polyaniline (PANI) to yield a hybrid ...
[EN] Poly(3,4-ethylenedioxythiophene) doped with poly-(styrenesulfonate), PEDOT¿PSS, films synthesized by electrochemical methods can be considered as poor electrocatalyst for the oxidation of ferrocene in aqueous solution. ...
The direct electron transfer between indium-tin oxide electrodes (ITO) and cytochrome c encapsulated in different sol-gel silica networks was studied. Cyt c@silica modified electrodes were synthesized by a two-step ...
[EN] The electrochemical copolymerization of aminoterephthalic acid (ATA) and o-aminophenol (OAP) was carried out on platinum electrodes in acidic medium. The obtained material, poly (ATA-co-OAP), can be deposited by cyclic ...
