| 1 | Optimization of Thermoelectric Microwave Power Sensors Based on Thin-Membrane Structure显示文摘In this work, the thermal conduction property of thermoelectric microwave power sensors is researched. The fabrication of the thermoelectric microwave power sensor consists of a front side and a back side processing using Ga As Monolithic microwave integrated circuit(MMIC) process and MEMS technology. An isolation structure on the front side is designed to prevent the thermal conduction from the resistor to the Coplanar waveguide(CPW). A thin-membrane on the back side is designed to prevent the thermal conduction from the resistor to the substrate. For the microwave power sensor without an isolation structure, the sensitivity is about 0.138, 0.136,0.132, 0.115 and 0.111 m V/m W at 8, 9, 10, 11 and 12 GHz,respectively. For the microwave power sensor with an isolation structure, the sensitivity is about 0.142, 0.139, 0.135,0.117 and 0.115 m V/m W at 8, 9, 10, 11 and 12 GHz, respectively. As a result, the higher thermal conduction efficiency and the higher sensitivity are obtained for the optimized thermoelectric microwave power sensors. | WANG Debo GAO Bo ZHAO Jiang ZHANG Yi GUO Yanyan | 2015 | Chinese Journal of Electronics2015，24，4： | 5 |

| 4 | Study on the Distribution of Frictional Forces on Z-yarn Continuous Implanted Preforms and Their Applications显示文摘To improve the quality and efciency of Z-directional 3D preform forming,the Z-yarn frictional force distribution model of the preform and its wear mechanism were investigated.In this study,a tensile force measuring device was designed to measure the force required to replace the guide sleeve,which is equivalent to the Z-yarn frictional forces.The frictional force is proportional to the number of preform layers and is applied to the preform decreased from the corner,edge,sub-edge,and middle in order.A back propagation neural network model was established to predict the friction at diferent positions of the preform with diferent layers,and the error was within 1.9%.The wear of Z-yarn was studied at diferent frictional positions and after diferent times of successive implantation into the preform.The results showed that with an increase in the number of Z-yarn implantations and frictional forces,the amount of carbon fber bundle hairiness gradually increased,and the tensile fracture strength damage of the fber was increasingly afected by the frictional forces.In the corner position of the preform,when the number of implantations was 25,the fber fracture strength decreased non-linearly and substantially;in order to avoid fber fracturing in the implantation process,the Z-yarn needs to be replaced in time after 20–25 cycles of continuous implantation.This study solves the problem of difculty in measuring the force required for individual replacements owing to the excessive number of guide sleeves,puts forward the relationship between fber wear,preform position,and implantation times,solves the phenomenon of fracture in the preform during Z-direction fber implantation,and realizes the continuous implantation of fbers. | Zitong Guo Zhongde Shan Jihua Huang Debo Xue | 2022 | Chinese Journal of Mechanical Engineering2022，35，4： | 0 |
| 5 | Multi-branched AgAuPt nanoparticles for efficient electrocatalytic hydrogen evolution:Synergism of tip-enhanced electric field effect and local electric field effect显示文摘High-curvature multi-noble metallic heterostructures can effectively enhance the electrocatalytic hydrogen evolution performance by utilizing the synergism of tip-enhanced electric field effect and local electric field effect.Herein,we report a two-step synthesis strategy to obtain multi-branched high-curvature Ag Au Pt heterostructure,firstly amino acids-induced growth of Au branches on Ag nanocubes,and secondly L-AA reduction of H_(2)PtCl_(6) to incorporate tiny Pt nanoparticles on Au branches.The D-CAgAuPt results in a low overpotential of 38 m V to deliver a cathodic current density of 10 m A cm^(-2),which is superior to commercial 20%Pt/C(46 m V).The strong electronic interactions between multi-noble metals intrinsically enhance the durability and stability of the catalysts.The intrinsic mechanism of promoting HER performance is investigated and revealed in-depth via the FDTD simulations and DFT calculations.In addition,D-CAg Au Pt can also achieve efficient and stable hydrogen evolution in a proton exchange membrane electrolyzer,which has the potential for commercial practical application.This work designs a novel multi-branched high-curvature multi-noble metallic heterostructure,and fully provides insights into the generical and efficient enhancement of electrocatalytic HER performance of multi-noble metallic heterostructures. | Wenliang Liu Xiaohan Li Yuqi Wang Debo Yang Zongzhen Guo Mengfei Liu Jiqian Wang | 2023 | Journal of Energy Chemistry2023，，6： | 0 |
