Iron-nitrogen co-doped hierarchical porous carbon (Fe-N-HPC) was synthesized through the carbonization of carbon nanotube@ZIF composite. It was found that the porous carbon structure with uniformly distributed active N-doping and Fe-N sites was conduced to oxygen adsorption, electronics, and mass transfer. In addition, the integrated electroconductive multi-walled carbon nanotube skeleton loaded with...
The mask-misalignment offset, as an inevitable part of the initial offset, is necessary to be reduced in the design of cross-like Hall devices. In this paper, a method is proposed to reduce the mask-misalignment offset. In order to find the method to reduce the mask-misalignment offset, the Hall sensors of different sizes and with different N-type doping regions are simulated by Silvaco Technology...
In this paper, we designed a group of horizontal Hall sensors in 0.35 µm BCD (bipolar/CMOS/DMOS) technology. Compared with the existing Hall devices, the design has improvement in parts such as Hall cell parameter set and layout design under BCD technology. And then the Hall chip is taped out. The results from the precise experiment of the Hall cell verify the optimization method which can be used...
The aerosol optical depth (AOD) has a weaken effect on the solar ultraviolet radiation, which has an important impact on human health. Taking the AOD weaken effect into consideration in the estimation of ultraviolet radiation helps to obtain an accurate result. However, the remotely sensed AOD has an uncertainty effect. By comparing the satellite remote sensing retrieval AOD with ground measured data...
