... shows that oxidation has occurred. For oxygen, the oxidation number has decreased from 0 to –2. This decrease in oxidation number shows that reduction has occurred. We now have four definitions of oxidation: 1. Gain of oxygen 2. Loss of hydrogen 3. Loss of electrons 4. Increase in oxidation number W ...

... In this circuit, we have three resistors and two batteries, one on either side of junction b. We can’t say that all the resistors are in series with each other, nor parallel, because of the placement of the batteries. If we want to find the current in and voltage across each resistor, we must use Ki ...

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.
