Aluminium owes its excellent cor-rosion resistance to the presence on the metal of a permanent film of natural oxide that consists of alumina (Al 2 O 3) and makes the metal ªpassiveº to the environ-ment. Although it is extremely thin, between 5 and 10 nanometers (3), the oxide film forms a protective barrier between the metal and the
anodizing”, a processes employed to form a protective anodic film on aluminium. Each of these processes may highlight some pre-existing surface or metallurgical condition of the aluminium alloy used. Such pre-existing flaws or inhomogeneities in the substrate alloy can result in a non-uniform appearance of the finished anodized surface. This,

The rectification ratio of the device is mainly detd. by the nanochannel size, and the rectification ratio is less sensitive to the patterned length of the amine groups when the nanochannels size is defined. Thus, the isoelec. point of nanochannels can be easily estd. to be the pH value with a unit rectification ratio.

Rectification is a process that converts electromagnetic fields into a direct current. Such a process underlies a wide range of technologies such as wireless communication, wireless charging, energy harvesting, and infrared detection. Existing rectifiers are mostly based on semiconductor diodes, with limited applicability to small-voltage or high-frequency inputs.
