... So where is the KE? Well it is in the shear volume of charge that flows through wires. There can be so much charge flowing that the wires get hot due to friction between the moving charges and the stationary metal that makes up the wires. This leads us to Resistance. The ampere is the basic unit of ...

Nanofluidic circuitry
Nanofluidic circuitry is a nanotechnology aiming for control of fluids in nanometer scale. Due to the effect of an electrical double layer within the fluid channel, the behavior of nanofluid is observed to be significantly different compared with its microfluidic counterparts. Its typical characteristic dimensions fall within the range of 1–100 nm. At least one dimension of the structure is in nanoscopic scale. Phenomena of fluids in nano-scale structure are discovered to be of different properties in electrochemistry and fluid dynamics.
