论文链接：https://doi.org/10.1016/j.nanoen.2024.110190Research BackgroundMetal halide perovskite has shown remarkable advancements in small-area perovskite solar cells (PSCs), achieving power conversion efficiencies over 26%. This progress is primarily due to enhanced passivation strategies and interface engineering. While small molecule passivators improve stability, they can volatilize and de...

1. Background introductionNear-α high-temperature titanium alloys are key structural materials for the manufacture of aero-engine rotation components. The compressor discs or blisks are held at peak stress for a period of time, resulting in a fatigue life that is less than the conventional low-cycle fatigue life, a phenomenon known as dwell fatigue. In service under stringent conditions, (0001...

1.IntroductionThe 26th United Nations Climate Change Conference (COP26) advocated for the decarbonization of the aviation industry. Hydrogen energy, characterized by its green, pollution-free nature, high energy density, abundant availability, and diverse application markets, is regarded as a crucial energy source for the future development of aviation. Consequently, the advancement of hydrogen...

论文链接：https://doi.org/10.1002/adma.202408268Research BackgroundThe substantial market share of lithium-ion batteries necessitates the development of sustainable recycling strategies. To date, while efforts have been made to extract metals (such as lithium, nickel, and cobalt) from layered metal oxides (LiMxO2) or lithium iron phosphate (LFP) cathodes using complex chemical processes, the ch...

Prof. Yue Ma group (School of Materials Science and Engineering, Northwestern Polytechnical University) recently published a paper entitled “Molten-Li Infusion of Ultra-Thin Interfacial Modification Layer towards the Highly-Reversible, Energy-Dense Metallic Batteries” on Energy Storage Materials (2022) 45: 796-804. In this research, they proposed an ultra-thin interfacial composite layer deri...
