Liu, Minne (author), Li, Wenyu (author), Chen, Wei (author), Ibrahim, Mesfin S. (author), Xiong, Jingkang (author), Zhang, Kouchi (author), Fan, Jiajie (author)During the operation of an LED array, its thermal and optical performances are always not equal to the superposition of the individual LED's characteristics because of a significant thermal coupling effect between the arrays. Based on this, this paper proposes an electrical–photo-thermal model, with considering both junction temperature and...journal article 2024

Mr. Wang, Q. (author), Xu, Tangjie (author), von Terzi, D.A. (author), Xia, Wei (author), Wang, Zhenhai (author), Zhang, Haoran (author)In existing wind farms, the overall power output can be increased through yaw control. However, the cooperative control of start/stop, yaw and turbines positions is often overlooked, leading to wake superposition to downstream wind turbines and suboptimal power output. This paper proposes a synchronized optimized method that considers start...journal article 2024

Templated Synthesis of Diamond Nanopillar Arrays Using Porous Anodic Aluminium Oxide (AAO) MembranesZhang, C. (author), Liu, Z. (author), Li, Chun (author), Buijnsters, J.G. (author)Diamond nanostructures are mostly produced from bulk diamond (single- or polycrystalline) by using time-consuming and/or costly subtractive manufacturing methods. In this study, we report the bottom-up synthesis of ordered diamond nanopillar arrays by using porous anodic aluminium oxide (AAO). Commercial ultrathin AAO membranes were adopted as...journal article 2023
