... One may be tempted to put the oxidatiion number of Barium within parenthesis such as Barium (II) and this is incorrect. Oxidation number is expressed in parenthesis only for transistion metal ions or metal ions which show variable oxidation numbers. Barium belongs to group 2 and all elements in grou ...

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.
