In-situ spectroelectrochemistry (UV-visible and infrared) of anodic films on iron in neutral phosphate solutions
(Pergamon-Elsevier Science Ltd, 2000-02)
The composition of anodic films on iron formed at different potentials in neutral solutions has been investigated by in-situ UV-vis and IR spectroscopies in the presence of PO43-, a non-contaminant inhibitor used in ...
A microwave-heated infrared reaction cell for the in-situ study of heterogeneous catalysts
(Facultad Experimental de Ciencias de la Universidad del Zulia, 2011)
Altering the adsorptive and electronic properties of Pt through poly(vinyl alcohol) adsorption
(2013-01-22)
In the present paper we investigated the effect of adsorbed PVA on Pt electrodes on classic electrochemical processes such as hydrogen UPD, oxygen reduction and CO electro-oxidation. Upon adsorption PVA blocks roughly 50% ...

Spectroelectrochemical studies of poly(N-methylaniline) formation, redox behaviour and degradation. A comparison with polyaniline
(Pergamon-Elsevier Science Ltd., 2014-03)
Spectroelectrochemical methods, in-situ Fourier Transform Infrared (FTIR) and Differential Electrochemical Mass Spectroscopy (DEMS), are used to study the formation of poly(N-methylaniline) (PNMANI) by anodic oxidation of ...
Conductive nanocomposites based on cellulose nanofibrils coated with polyaniline-DBSA via in situ polymerization
(2012-09-01)
Cellulose nanofibrils (CNF) were extracted by acid hydrolysis from cotton microfibrils and nanocomposites with polyaniline doped with dodecyl benzenesulphonic acid (PANI-DBSA) were obtained by in situ polymerization of ...
