The second study was designed to contribute to the current focus on the protection of silver artifacts by electrochemically grown poly-3-amino 1,2,4-triazole (PAta) [304], There is evidence that the dissolution of a silver copper alloy is inhibited by Ata adsorption with interaction with oxidation species (see Fig. 6.3). 

Metal oxides which undergo proton insertion reactions find extensive application in batteries and are currently being investigated as potential electrochromic materials. The properties of battery oxides, e.g. manganese dioxide [107-110] and nickel [111-114] have been extensively reviewed in the literature and will therefore not be discussed here. Rather, the properties of electrochemically grown, electrochromic oxide films will be described since this is a relatively new and interesting field.

An example illustrating the nondestructive analysis of a locked-in interface is shown in Figure 9 (2 ). Here, a similar computation is performed to yield the dielectric function of an electrochemically grown anodic oxide on a CdTe substrate where one of the free parameters is the thickness of an assumed interfacial layer of a-Te. Interference-related artifacts are minimized for 1.5 2A of a-Te between substrate and oxide. Similar calculations for HgTe, Hg gCdg 90 29 0 71 8 °" ... 

A a-Te at these interfaces. The results demonstrated that the relatively large ( 30A) amounts of a-Te typically found at the interfaces between these materials and their electrochemically grown anodic oxides by destructive analyses are artifacts of ion milling. 

Polymer-based, variable light transmission electrochromic devices have been fabricated with counter-electrodes that are either optically passive or electrochromic in the complementary mode. Two devices with pMeT, electrochemically grown by monomer oxidation on ITO-coated glass as the electrochromic electrode, having colourless counter-electrodes in both oxidized and reduced states, and operating in liquid electrolyte, such as PC-LiC104, have been developed [29, 30]. 

The absorption spectrum of an electrochemically grown nickel oxide film shows a peak in the vicinity of 0.5-0.6 pm. Therefore, depending on film thickness, nickel oxide is transparent or pale green in the bleached state and brown-bronze in the coloured state.

A typical cyclic voltammogram is shown in Fig. 2 for a polypyrrole film. The polypyrrole film was electrochemically grown on a 0.5-cm platinum electrode in a solution of 0.1 M tetraethylammonium tetrafluoroborate in acetonitrile [46]. The oxidation wave in the anodic sweep produced a reduction wave on the reverse cathodic sweep. Different diffusion processes involved most likely account for the different shapes of the oxidation and reduction waves. For example, when lithium perchlorate is the electrolytic salt, perchlorate anions diffuse into the polymer upon oxidation. However, upon reduction the more mobile lithium cations diffuse in... 

The 0.785-mm Ir working electrodes were then electrochemically activated to build up a layer of iridium oxide on each. The porous oxide was grown to increase the surface area available for antibody immobilization on the electrode. Drops of solution containing the appropriate antibodies were then applied over the working electrodes, and the array was incubated at 4 C to complete the immobilization.
