Electrochemical deposition has two main advantages over chemical reduction. First, it is much faster with most deposition completed within five minutes. Second, the size of the metal nanoparticles and their coverage on the nanocarbon can be controlled by the concentration of the metal salt and various electrochemical deposition parameters, including nucleation potential and deposition time [124,127,205].

Lanthanides have been refined, isolated, and separated using techniques such as ion-exchange and solvent (liquid-liquid) extraction, and electrochemical deposition. Recently, a technique was developed for separating rare earths employing selective reduction and fractional distillation (Hedrick 2000). An advantage of the new process is that it achieves separations two orders of magnitude greater than liquid-liquid extraction however, the process is... 

In this work, ac electrochemical deposition has been applied to nanowire formation in PAA. The advantage of the ac electrochemical deposition is that the membrane remains on the A1 substrate and that the barrier layer does not avoid the deposition. In this case, the fabrication of ordered and metal-filled porous alumina structures is not limited by the thickness and size of the PAA layer. These structures may be used in high temperature technological operations. 

Coin-type nonaqueous rechargeable batteries are used in the field of backup power source for electroiuc devices, because of their advantages, such as high energy density and Ught weight. In the case of a battery based on lithium, lithium has to be pressure-welded or electrochemically deposited to the negative electrode. 

The most widely applicable approach splits the fabrication of nanopatterned functional materials into two successive steps, namely the self-assembly driven formation of mesoporous templates and the replication of the templates with functional materials, as illustrated in Fig. 1.3. This strategy to nanostructured functional materials has the major advantage that it allows for the independent optimization of the template preparation. Since the same template can be used to structure various functional materials applying different replication techniques, such as sol-gel, atomic layer deposition (ALD), electrochemical deposition, and electroless plating, it is considered as an extremely versatile approach [14-17]. 

The measurements of metaUurgically prepared alloys, which were used as alloy electrodes in cells as in Figure 3.7, are limited in their number of data points. A big advantage that was introduced by Wagner is the coulometric titration. The cell is either a two-electrode cell or a three-electrode cell with a solid electrolyte or a molten salt electrolyte. The alloy is not preformed but is formed instead by a slow electrochemical deposition of component A into the component B (current 1). The mole number of A deposited is determined by the equation... 

So far an ideal interface between a metal and an electrolyte has been considered. Neither the solvent nor any other component of the electrolyte (except the metal ions) can adsorb on the metal interface. The advantage of electrochemical deposition is the possibility to modify this ideal surface by additives, which adsorb on the metal surface. The additives have different effects, which can be used as a characterizing feature like brightening or leveling the deposit. 

Conductive polymer nanostructures synthesized using porous silieon (PSi) templates are described, with an emphasis on PSi template advantages, pore-filling phenomenon, meehanism of polymerization, and selective removal of PSi to release the polymerie struetures. The interaction of pyrrole monomers, as a case study, on the entire surfaee of PSi under both galvanostatic and potentiostatie deposition modes is presented with discussion on the processing issues assoeiated with the electrochemical deposition process inside the pores. Additionally, various materials infiltrated into PSi templates are briefly deseribed. Examples of fi ee-standmg conductive polymer structures formed by selective dissolution of PSi are provided.
