Zhu, Yifan (author), Lu, Huimin (author), Wang, Jianping (author), Yu, Tongjun (author), Li, Z.Z.L. (author), Tian, Yucheng (author)In order to improve the light extraction of AlGaN-based short wavelength ultraviolet light emitting diodes (DUC-LEDs), a type of microstructure with high aspect ratio is introduced and optimized on the AlN substrate surface. And, particle swarm optimization (PSO) algorithm is used to inverse design of the surface microstructure to maximize...journal article 2023

Wang, Yawen (author), Hou, Longgang (author), Su, Hui (author), Tian, Qingkun (author), Yu, Kangcai (author), Eskin, Dmitry (author), Katgerman, L. (author), Zhuang, Linzhong (author)The alloy design and homogenization processes are intimately associated with the microstructure, phase composition and performance for Al-Zn-Mg-Cu alloys. The microstructures and phase composition of a series of Al-Zn-Mg-Cu alloys before and after the homogenization treatments were investigated along with thermodynamic calculation to...journal article 2022

Tian, Zhan (author), Yu, Ziwei (author), Li, Yifan (author), Ke, Q. (author), Liu, Junguo (author), Luo, Hongyan (author), Tang, Yingdong (author)Climate change and rapid urbanization have made it difficult to predict the risk of pollution in cities under different types of rainfall. In this study, a data-driven approach to quantify the effects of rainfall characteristics on river pollution was proposed and applied in a case study of Shiyan River, Shenzhen, China. The results indicate...journal article 2022
