“…Electrodeposition is a very convenient method for material synthesis, due to its simplicity, rigid control of film thickness, uniformity, and deposition rate and is especially attractive due to low equipment cost [26]. Bi2O3 films and powders have been electrochemically synthesized by direct cathodic deposition from Bi (III) solutions [27][28][29][30], and by cathodic electrodeposition of bismuth metal, followed by its further anodic oxidation [31].…”

This paper reports the synthesis, characterization and application of a Ti-Bi2O3 anode for the electrochemical decolorization of the textile dye Reactive Red 2. The anode was synthesized by electrodeposition on a Ti substrate immersed in an acidic bismuth (III) solution at constant potential, followed by calcination in air at 600°C. Thermogravimetric Analysis (TGA), Energydispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD) analysis revealed that the electrodeposited material was predominantly metallic bismuth, which was oxidized to pure α-Bi2O3 during the calcination in air. SEM micrographs revealed that the Bi2O3 coat at the anode surface was inhomogeneous and porous. Reactive Red 2 was completely electrochemically decolorized at the synthesized anode in the presence of H2O2. The applied current density, H2O2 and Na2SO4 concentration, medium pH and initial dye concentration affected the dye decolorization rate. The optimal process parameters were found to be as follows: an applied current density of 40 mA cm -2 using a mixture of 10 mmol dm -3 H2O2 and 10 mmol dm -3 Na2SO4 at pH 7. The dye decolorization rate was shown to decrease as its initial concentration increased. The decolorization reactions were found to follow pseudo-first order kinetics.

“…Electrophoretic deposition allows the deposition of coating from almost any material class, including metals, polymers, and ceramics (93)(94)(95)(96). The mechanism of electrophoretic deposition involves electrophoresis, in which charged particles move toward an electrode of opposite charge, and deposition, due to the motion of charged particles and their local accumulation.…”

“…The mechanism of electrophoretic deposition involves electrophoresis, in which charged particles move toward an electrode of opposite charge, and deposition, due to the motion of charged particles and their local accumulation. Coating formation is achieved via particle coagulation (93)(94)(95)(96). EPD appears of particular interest in surface modifications of materials for biomedical application (48,78) because the deposition of either inorganic or hybrid coatings with high purity is possible on complex geometries.…”

Int J Artif Organs ( 2011; : 9) 929-946 34 TITANIUM OXIDE AND ANTIBACTERIAL SURFACES IN BIOMEDICAL DEVICES Device-related infections: a clinical demand driving material science researchAn increasing number of clinical procedures requires the use of biomedical devices, whose widespread presence in modern therapeutic treatments is driving the demand for better performances and longer reliability. One of the major issues of both short-term devices and implantable prostheses is represented by device-related infections (DRIs) Accepted: August 31, 2011 rEViEW due to bacterial colonization and proliferation (1). About half of the 2 million cases of nosocomial infections that occur each year in the United States are associated with indwelling devices (2): these infections generally require a longer period of antibiotic therapy and repeated surgical procedures, resulting in potential risks for the patient and increased costs for the healthcare system. The planktonic bacteria that colonize a device surface tend to form a biofilm and the sessile bacterial cells, enclosed in a self-produced polymeric matrix of this kind, can withstand host immune responses and generally show extraordinary antibiotic resistance (3). Eventually, bacteria rapid multiply and disperse in planktonic form, giving rise

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 nanocomposite electrode, which was then characterized by both electrochemical and imaging techniques. The electrochemical properties of the SWCNT@SiO2-PANI composite material were tested against inorganic (Fe 3+ /Fe 2+ ) and organic (dopamine) redox probes. It was observed that the electron transfer constants for the electrochemical reactions increased significantly when a dispersion of either SWCNT or PANI was carried out inside of the SiO2 matrix.However, the best results were obtained when polyaniline was grown through the pores of the SWCNT@SiO2 material. The enhanced reversibility of the redox reactions was ascribed to the synergy between the two electrocatalytic components (SWCNTs and PANI) of the composite material.
