The industrial economy depends heavily on electrochemical processes. Electrochemical systems have inherent advantages such as ambient temperature operation, easily controlled reaction rates, and minimal environmental impact (qv). Electrosynthesis is used in a number of commercial processes. Batteries and fuel cells, used for the interconversion and storage of energy, are not limited by the Carnot efficiency of thermal devices. Corrosion, another electrochemical process, is estimated to cost hundreds of millions of dollars aimuaUy in the United States alone (see Corrosion and CORROSION control). Electrochemical systems can be described using the fundamental principles of thermodynamics, kinetics, and transport phenomena.

The facility was operated for the first time in May 1969, and since 1973 it is out of operation because of corrosion problems in the structural aluminium tubes and in the spacing plates, one of them particularly highly corroded. At present, the fuel is kept in storage boxes, and the tank is empty. The neutron source is in its storage device, which is appropriately shielded. The fuel cylinders are in good condition and are periodically inspected thoroughly by visual and X ray inspection. 

For making CDI electrodes, we cannot use single carbon particles but need a film composed of such particles. Commonly, film electrodes for CDI are prepared similar to electrodes used for energy storage devices carbon powders are mixed with a polymeric binder (usually -10 wt%) and often some conductive additive like carbon black (CB). The components are thoroughly mixed, rolled, and dried, or directly cast on the current collector the latter may be a graphite foil to avoid corrosion in saline water. A very elegant way to avoid both the use of polymeric binder and possible wash-out of powder particles is the use of a porous monolith, an interwoven array of (porous) fibers, or carbon felts and fabrics. When such structured electrodes are either not available or undesired (e.g., because of cost considerations), a film electrode made from a carbon powder can either be protected by a membrane (see also MCDI) or mechanically stabilized by a porous separator which enables saline water flow. 

Polyaniline has potential applications in areas such as organic semiconductors, corrosion inliibitors, color displays, energy storage devices, optoelectronic devices, and rechargeable pofymer batteries. This polymer has been endowed with desirable electrical, electrochemical, and optical properties coupled with excellent environmental stability [278-287].

The critical metallic components of advanced magnetic and magneto-optic (MO) storage devices— thin-film metal disks, inductive or magnetoresistive heads, and MO layers—are all susceptible to corrosion and each has been a subject of considerable study. Several review articles covering corrosion of magnetic-storage media may be found in the literature [135,136].
