... Acid/base problems may fall into 4 categories: strong acid/base, weak acid/base, buffers and hydrolysis. We will go through examples of each of these types of problems one at a time. Strong Acids and Strong Bases The strength of the acid is determined by how far the equilibrium lies to the right. Qu ...

TWO STEP CURRENT INCREASES IN GLOW
... For position in front of the cathode (z = 17.5 mm), light intensities and current signals are observed practically simultaneously, as can be seen in Fig. 3. The simultaneously detection of emitted light and current at positions from z = 17.5 mm to z = 26.5 mm indicates that the concentration of elec ...

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.
