Chapter 6 Chemical Bonding
... How does covalent and ionic bonding differ at the atomic level? Ionic bonding: An e- is actually transferred from one atom to the other This causes the donator to shrink and the acceptor to enlarge The donator becomes (+) and the acceptor (-) Structure is held together because of opposites a ...

Basic Electricity
... This was a 33 W resistor connected to a 20 V supply. The current would be 20 V ÷ 33 W = 0.61 A The power would be 0.61 × 20 V = 12 watts. Plenty enough to fry a 1 watt resistor. It is important that we ensure that any current limiting resistors can dissipate the power through them. The above situati ...

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.
