Pore-Scale Controls on Reaction-Driven Fracturing - DUO
... We will now take a closer look at the pore-scale mechanisms that lead to the stresses and fracture patterns discussed in the preceding section. The key requirement for reactions to take place is that water has access to the reactive surface. In the examples given below, we will show how fracturing c ...

... Refer to Figure 10.34a in the book. (a) If vin (t ) 0, we have only a dc source in the circuit. In steady state, the capacitor acts as an open circuit. Then we see that D2 is forward conducting and D1 is in reverse breakdown. Allowing 0.6 V for the forward diode voltage the output voltage is -5 V. ...

How to Make Linear Mode Work
... Since the transfer characteristic crossover point is at a relatively high current, linear mode operation is almost always in the thermally unstable area below the crossover point. The problem is that the hotter areas on the die have higher current density, thus reinforcing hot spotting. Every MOSFET ...

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.
