Group 1 - The first domestically developed 3D printed turbojet engine has successfully completed its maiden flight test, filling a gap in the application of 3D printing technology in engine manufacturing in China. The engine operated stably in high-altitude complex environments, meeting all design parameters, and demonstrated reliability. The test flight was conducted in Dingbian County, Shaanxi, with the drone flying for 30 minutes, reaching a maximum speed of 0.75 Mach and an altitude of 6000 meters. No damage or failure was observed in any engine components after the test [2]. - The domestically produced manned airship, Xiangyun AS700, has achieved the first commercial flight in China, completing a round trip from Jingmen to Wuhan. This airship is the first in China designed according to airworthiness standards and possesses complete independent intellectual property rights for short-distance and vertical takeoff and landing [2]. - A research team from Xi'an Jiaotong University and Xiamen University has proposed a new solid-state molecular imprinting annealing strategy to enhance the stability of perovskite solar cells. This research was published in the international journal "Science" [2]. - The first domestically produced BOPP production line with a width of 9.1 meters has been successfully launched in Guilin, marking a significant breakthrough in core technology in the high-end film equipment sector. This production line increases the maximum width of similar domestic equipment from 8.7 meters to 9.1 meters and features low consumption, high efficiency, and green advantages. The produced BOPP film has excellent mechanical and electrical properties, as well as outstanding cold resistance and gas tightness, making it widely applicable in high-end packaging fields such as electronics and medical supplies [2].

Core Viewpoint - A new solid-state molecular imprinting annealing strategy has been proposed by a collaboration between Professor Liang Chao's team at Xi'an Jiaotong University and Professor Zhang Jinbao's team at Xiamen University, aimed at enhancing the stability of perovskite solar cells [1] Group 1 - The research focuses on the field of perovskite materials and device physics [1] - The findings were published online in the international academic journal "Science" on January 9 [1]

Core Viewpoint - Perovskite solar cells are gaining attention due to their high efficiency, simple manufacturing process, and low cost, but the heat annealing process can induce crystal defects that limit their performance and stability [2][4]. Group 1: Research Findings - A new solid-state Molecular Press Annealing (MPA) strategy has been proposed, which involves imprinting a dense layer of pyridine-based molecular template on the perovskite surface during the heat annealing process, allowing for real-time repair of iodine vacancies and stabilization of the lead-iodine framework [5][6]. - The MPA strategy enhances the structural integrity and long-term stability of perovskite films, addressing the limitations caused by traditional heat annealing [5]. Group 2: Performance Metrics - The n-i-p structured perovskite solar cells fabricated using the MPA strategy achieved a power conversion efficiency (PCE) of 26.6% for small area devices (0.08 cm²) and 24.9% for 1 cm² devices, maintaining 23.0% efficiency for 16 cm² modules [7]. - The devices demonstrated exceptional durability, retaining 98.6% and 97.2% of their initial efficiency after 1617 hours of continuous operation at maximum power point and 5280 hours of atmospheric storage, respectively [7].
