This may alter the relationship between electrode activity and pH. In order to exclude or identify possible contributio ...
Limits and hints how to turn off IGBTs with unipolar supply AN1401
... Figure 10 shows the curves measured on IGBT T2 and diode D2 upon turn-on of the complementary IGBT T1. When T1 turns on, the current commutates from the freewheeling diode D 2 to IGBT T1. The commutation speed depends on the switching speed of IGBT T1 and the commutation inductance. From the beginni ...

This 2-level turn-off sequence takes place at each cycle; it has no effect if the current doesn’t exceed the normal maximum rated value, but protects the IGBT in case of overcurrent (with a slight increase to conduction losses). The principle is shown on Figure 12. During the 2-leve ...

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.
