1Optimized Design of Multi-Layer Absorber for Human Tissue Surface显示文摘In this paper,the structure optimization scheme of multi-layer absorber on the surface of human tissue is designed.The absorber uses graphite,foam and other materials to build a resistance loss layer.Solve the electromagnetic parameters of graphite through its characteristics,use the equivalent transmission line theory to calculate the reflection coefficient.Establish the objective function of the reflection coefficient,and use genetic algorithm to optimize the design of the absorbing device.The experimental results show that compared with the Jaumann type three-layer absorber,the reflection coefficient of the multi-layer absorber optimized by genetic algorithm in this paper has decreased by nearly 13 dB.From the analysis of error and sensitivity,it can be concluded that when the material thickness error is within the range of±0.005 mm,the microwave absorption performance error of the multilayer absorber is about 5%.Within this error range,the performance of the multilayer absorber can be guaranteed.The sensitivity analysis results of the materials in each layer of the absorber indicate that the concentration and thickness of the graphite layer have the greatest impact on the performance of the absorber.TU Botao YE Mengqiu YANG Zhen LI Jinfeng LI Guanghui ZHANG Yuejin 2023Chinese Journal of Electronics2023,32,4:0
2Direct Electron Transfer from Upconversion Graphene Quantum Dots to TiO_(2) Enabling Infrared Light-Driven Overall Water Splitting显示文摘Utilization of infrared light in photocatalytic water splitting is highly important yet challenging given its large proportion in sunlight.Although upconversion material may photogenerate electrons with sufficient energy,the electron transfer between upconversion material and semiconductor is inefficient limiting overall photocatalytic performance.In this work,a TiO_(2)/graphene quantum dot(GQD)hybrid system has been designed with intimate interface,which enables highly efficient transfer of photogenerated electrons from GQDs to TiO_(2).The designed hybrid material with high photogenerated electron density displays photocatalytic activity under infrared light(20 mW cm^(-2))for overall water splitting(H_(2):60.4μmol g_(cat).^(-1)h^(-1)and O_(2):30.0μmol g_(cat).^(-1)h^(-1)).With infrared light well harnessed,the system offers a solar-to-hydrogen(STH)efficiency of 0.80%in full solar spectrum.This work provides new insight into harnessing charge transfer between upconversion materials and semiconductor photocatalysts and opens a new avenue for designing photocatalysts toward working under infrared light.Dongmei Jia Xiaoyu Li Qianqian Chi Jingxiang Low Ping Deng Wenbo Wu Yikang Wang Kaili Zhu Wenhao Li Mengqiu Xu Xudong Xu Gan Jia Wei Ye Peng Gao Yujie Xiong 2022Research2022,,3:0
