    Ultra-Fast Tunable Optical Delay Line Based on Cascaded Silicon Microdisk Resonators Yuwen Xu, Weifeng Zhang, Bin Wang

    出版 2023-01-01

    Integrated optical delay lines (ODLs) featuring fast and continuous tunability are important building blocks in microwave photonic signal processing systems. In this work, we propose and demonstrate an ultra-fast tunable ODL based on cascaded silicon microdisk resonators (MDRs). In the proposed inte...

    Hybrid Additives of 1,3-Diketone Fluid and Nanocopper Particles Applied in Marine Engine Oil Yuwen Xu, Yan Yang, Li Zhong, Xingyuan Jing, Xiaoyu Yin, Tao Xia, Jingsi Wang, Tobias Amann, Ke Li

    出版 2025-06-01

    The lubrication performance of the cylinder liner–piston ring (CLPR) is crucial for the energy efficiency and operating reliability of marine diesel engines. To enhance the boundary lubrication of marine engine oil, a 1,3-diketone fluid HPTD (1-(4-hexylphenyl) tridecane-1,3-dione, HPTD) was introduc...
