Removal rate and durability are the two most important parameters of an ideal air purification filter to remove inhalable particles toxic gases. Here, based on interaction a local electric field external field, novel coaxial core–shell CuO@NH2-MIL-53(Al) nanowire array was synthesized rigid copper net, which used PM2.5 SO2 simultaneously. The removal rates by with without can reach 98.72% 44.41...
Electric fields at interfaces exhibit useful phenomena, such as switching functions in transistors, through electron accumulations and/or electric dipole inductions. We find one potentially unique situation in a metal-dielectric interface in which the electric field is atomically inhomogeneous because of the strong electrostatic screening effect in metals. Such electric fields enable us to acce...
An electric-field-induced second-harmonic-generation signal in a nematic liquid crystal is used to map the electric field in an integrated-circuit-like sample. Since the electric-field-induced second-harmonic-generation signal intensity exhibits a strong dependence on the polarization of the incident laser beam, both the amplitude and the orientation of the electric field vectors can be measure...
The ability of cells to sense and respond to endogenous electric fields is important in processes such as wound healing, development, and nerve regeneration. In cell culture, many epithelial and endothelial cell types respond to an electric field of magnitude similar to endogenous electric fields by moving preferentially either parallel or antiparallel to the field vector, a process known as ga...
Tailoring electromagnetically induced transparency with two different coupling mechanisms has been numerically demonstrated. The results show that EIT based on simultaneous electric resonance and magnetic resonance has relatively larger coupling distance compared with that based on electric resonance near field coupling to magnetic resonance. The relatively large coupling distance is due to the...
Sandstorm has an effect on the electric field characteristics of outdoor insulator, and may result in flashover. The analysis of the electric field characteristic of insulator under sandstorm condition is very important. The electrostatic field finite element method (FEM) is used to calculate the electric field distribution along long rod insulator under sandstorm condition with FEM software. T...
Electrospinning technique is currently one of the most important methods for preparing nanofiber. It is important and essential to analyze the distribution of electric field in electrospinning machine. The electric field’s distribution in the typical electrospinning device was calculated and analyzed based on finite element calculation theory of electric field. The electric field is optimized b...
