In this paper, the electrode effects on mass sensitivity of GaN thin film bulk acoustic wave resonator (FBAR) sensors have been studied. The equation of electric impedance of FBARs with structure of mass sensitive layer/electrode/GaN/electrode has been derived by one dimensional transmission line model for frequency calculation. In the simulation, to produce shear mode acoustic 2µm GaN with 42.8°...
In the process of actual fire rescue, the timeliness and success rate of fire rescues will be affected when only one lifeline system is considered and not considered the relationship among other lifeline systems. However, little research was paid attention to the relationship among different lifeline systems and the most of studies was focused on a single lifeline system. Therefore, it is important...
Previously we found that exposure to electromagnetic pulse (EMP) induced an increase in blood–brain-barrier (BBB) permeability and the degradation of tight junction protein ZO-1 in rats. Matrix metalloproteinases (MMPs), in particular gelatinases (MMP-2 and MMP-9), play a key role in degradation of tight junction proteins, are known mediators of BBB compromise. We hypothesized that the degradation...
