The electrodeposition of gold and platinum complexes at the electrochemical interfaces on the coronene-modified Au(111) surface was investigated. Scanning tunneling microscopy revealed the spontaneous deposition of gold and platinum complexes, suggesting that the coronene adlayer plays an important role in the electroreduction of these complexes.

Composite coatings containing brushite (CaHPO(4). 2H(2)O) and chitosan were prepared by electrochemical deposition. The brushite/chitosan composites were converted to hydroxyapatite/chitosan composites in aqueous solutions of sodium hydroxide. The coatings ranged from approximately 1 to 15% chitosan by weight. Qualitative assessment of the coatings showed adhesion significantly improved over th...

Modification of carbon materials, especially graphene-based materials, has wide applications in electrochemical detection such as electrochemical lab-on-chip devices. A glassy carbon electrode (GCE) modified with chemically alternated graphene oxide was used as a working electrode (glassy carbon modified by graphene oxide with sulphur containing compounds and Nafion) for detection of nucleobase...

Thin films of orthorhombic V2O5 have been prepared by sol electrophoretic deposition (EPD) followed by post-treatment at 500 ◦C. Their electrochemical and optical performances have been investigated for possible applications in electrochemical/electrochromic devices. Li+-intercalation properties of the films have been explored in two voltage ranges: 0.4 to −1.1 V and 0.4 to −1.6 V versus Ag/Ag+...

Films of undoped polycrystalline diamond were deposited on molybdenum or graphite substrates by hot filament chemical vapour deposition (HFCVD), using a precursor gas mixture of methane in excess hydrogen. The morphology and quality of the as-deposited films were monitored by scanning electron microscopy, Raman spectroscopy, and X-ray diffraction, and the electrochemical activity monitored with...

Nanostructured ultrathin films of pendant carbazole-modified polyelectrolytes were fabricated using the layer-by-layer deposition technique in order to correlate the importance of highly ordered structures and well-defined layer composition in electrochemical cross-linking and nanopatterning. Both UV-vis and surface plasmon resonance (SPR) spectroscopy studies indicated differences in the film ...

This review introduces and summarizes the fundamentals and various technical approaches developed for the template-based synthesis of nanorod, nanowire and nanotube arrays. After a brief introduction to various concepts for the growth of nanorods, nanowires and nanobelts, attention will be focused mainly on the most widely used and well established techniques for the template-based growth of na...

This chapter introduces the fundamentals of and various technical approaches developed for template-based synthesis of nanorod arrays. After a brief introduction to various concepts associated with the growth of nanorods, nanowires and nanobelts, the chapter focuses mainly on the most widely used and well established techniques for the template-based growth of nanorod arrays: electrochemical de...

It is reported in this article that Si nanowires can be employed as a positive template for the controllable electrochemical deposition of noble metal tube. The deposited tube exhibits good crystallinity. Scanning electron microscope and transmission electron microscope characterizations are conducted to reveal the growth process of metal tube, showing that the metal tube grows quasi-radially o...

Thermal behavior of polarized Pd/D electrode, prepared by the co-deposition technique, serving as a cathode in the Dewar-type electrochemical cell/calorimeter is examined. It is shown that: (i) excess enthalpy is generated during and after the completion of the co-deposition process; (ii) rates of excess enthalpy generation are somewhat higher than when Pd wires or other forms of Pd electrodes ...
