Metal oxide charge transport materials are preferable for realizing long-term stable and potentially low-cost perovskite solar cells(PSCs).However,due to some technical difficulties(e.g.,intricate fabrication protocols,high-temperature heating process,incompatible solvents,etc.),it is still challenging to achieve efficient and reliable all-metal-oxide-based ***,we developed efficient inverted PSCs(IPSCs)based on solution-processed nickel oxide(NiO_(x))and tin oxide(SnO_(2))nanoparticles,working as hole and electron transport materials respectively,enabling a fast and balanced charge transfer for photogenerated charge *** further understanding and optimizing the perovskite/metal oxide interfaces,we have realized an outstanding power conversion efficiency(PCE)of 23.5%(the bandgap of the perovskite is 1.62 eV),which is the highest efficiency among IPSCs based on all-metal-oxide charge transport *** to these stable metal oxides and improved interface properties,ambient stability(retaining 95%of initial PCE after 1 month),thermal stability(retaining 80%of initial PCE after 2 weeks)and light stability(retaining 90%of initial PCE after 1000 hours aging)of resultant devices are enhanced *** addition,owing to the low-temperature fabrication procedures of the entire device,we have obtained a PCE of over 21%for flexible IPSCs with enhanced operational stability.

The development of tourism in historic areas imposes immense pressure on heritage conservation, leading to issues such as commercial encroachment and the loss of cultural uniqueness in many domestic areas. Dayan Ancient Town, as an integral part of the Old Town of Lijiang, a World Cultural Heritage Site, faces increasing challenges due to commercialization. This paper explores the cultural and commercial development of Dayan Ancient Town from the perspective of tourist perception. Using the Analytic Hierarchy Process(AHP), this study develops an evaluation system and visualization to analyze both cultural and commercial perceptions of tourists. The findings reveal that tourists' cultural perception of the town is limited, while their commercial perception is prominent. Furthermore, the study examines the distribution of cultural attractions and commercial establishments, revealing that the current cultural attractions can't contribute to high and continuous cultural perception results. The study finally proposes recommendations for enhancing tourist perception of the ancient town, such as establishing multi-level protection and development strategies, infusing cultural attributes into business, and expanding cultural attraction clusters.

为探究电场对微细通道流动沸腾传热的影响,设计了一种针状电极布置方案将电场引入到微细通道中,以制冷剂R141b为实验工质,在设计系统压力为140kPa、入口温度为32.5℃工况下进行流动沸腾实验。研究结果表明:电场对制冷剂R141b在微细通道内的流动沸腾传热效果有显著影响,引入电场会导致过冷沸腾起始点(ONB点)提前,强化了传热效果,相对于无电场的情况,250V、550V、850V这3种电压下达到ONB点所需过热度分别减小了0.6℃、1.26℃、1.78℃;电场能够显著强化位于ONB点后下游区域的沸腾传热,局部传热系数随着电压的增大而增大,在本实验工况下局部沸腾传热系数最大提高了89.7%;将3种传热模型进行对比,发现Sun-Mishima模型预测效果最好,引入电压参数U对其修正,修正后的模型能更好预测本实验工况下的传热系数实验值,平均绝对误差为12.2%。
