The electrochemical study of certain azulene bis azo derivatives meta or para substituted is connected to the potential applications (enhanced NLO coefficients [1] and electrochromic behaviour) of this type of compounds. New compounds were studied by cyclic (CV) and differential pulse voltammetry (DPV), in TBABF4 0.1 M, CH3CN or CH3CHCl2 in order to find some rules regarding the influence of substituents...
Ruthenium porphyrin functionalised single-walled carbon nanotube arrays have been prepared using coordination of the axial position of the metal ion onto 4-aminopyridine pre-assembled single-walled carbon nanotubes directly anchored to a silicon(100) surface (SWCNTs-Si). The formation of these ruthenium porphyrin functionalised single-walled carbon nanotube array electrodes (RuTPP-SWCNTs-Si) has been...
In this paper, the processes associated with the electrodeposition of Selenium on Au substrates from nitric acidic solutions were investigated by combined electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) measurements. The analyses reveal that H2SeO3 in the solution is firstly adsorbed on the surface of Au electrode during cathodic polarization and subsequently reduced to Se...
