蝙蝠以大毒王闻名于世，却是人类实实在在的良师益友。它具有控制害虫、种子传播、植物授粉等不可或缺的生态作用和巨大的经济价值，且在健康长寿、生物仿生等方面具备重要的研究意义。作为唯一会飞行的哺乳动物，人们对它的观察与研究从未停止。蝙蝠声纳系统的发现见证了人类探求真理的曲折历程和顽强精神。蝙蝠拥有“心眼”这样的超能力，人类依据其回声定位和形体结构制造出蝙蝠机器人，未来应用及发展前景非常广阔。蝙蝠还是中国福文化的代表，值得我们永远颂扬。论文讲述了蝙蝠的优缺点、身体结构、生活习性和夜视能力以及蝙蝠机器人的相关知识，旨在引领学生全面辩证地看待蝙蝠的问题，培养学生的思辨意识和能力，体会仿生学的奥妙，传承中华传统福文化思想精髓，树立人与自然和谐共生的发展观。

In this study, ZnSnO₃/NiO heterostructures were synthesized using a co-precipitation method followed by an annealing process. The gas-sensitive characteristics of the sensors based on these samples were evaluated. The results indicate that the sensor performance was optimized when the molar ratio of Ni to Zn was 1∶2. Specifically, the response values of the ZnSnO₃/NiO-2-based sensor to 100 μL·L^-1 triethylamine (TEA) gas at 220 ℃ reached 70.6, which were 6.1 times higher than that of the pure ZnSnO₃ based sensor. The findings demonstrate that ZnSnO₃/NiO heterostructures exhibited not only short response and recovery times (1 s/18 s) but also good gas selectivity, repeatability, and long-term stability. The enhanced sensing mechanism has been investigated in detail.

聚N-异丙基丙烯酰胺(PNIPAm)交联温敏纳米纤维膜作为一种相变温度易于控制的新兴响应性材料，克服了传统PNIPAm块状水凝胶的生产成本高、响应速率慢和PNIPAm非交联温敏纳米纤维耐水性差的缺点，受到广泛研究并应用于智能开关、温度致动器、水油分离、药物、细胞控制释放和伤口敷料等领域。形貌稳定性和快速响应性是温敏纳米纤维膜在重复体积变化过程中最大的挑战，同时也作为评价PNIPAm温敏纳米纤维膜的实用性最重要指标引起了人们广泛的关注。本文全面综述了PNIPAm温敏纳米纤维膜近二十年来国内外的突破性进展和非交联作用下PNIPAm温敏纳米纤维膜的形貌变化和响应性，重点综合分析了物理和化学交联中交联反应类型、交联度、交联时间和交联分子量对PNIPAm温敏纳米纤维膜的形貌稳定性和响应行为的影响，为之后纤维膜的交联处理提供了理论支持，并对PNIPAm温敏纳米纤维膜的发展及应用前景进行了展望。

Herein, an FMS/CC composite was successfully fabricated by depositing FeMoS₄ onto a pristine carbon fiber cloth (CC) substrate via a facile two-step hydrothermal method. The amorphous nature of the FMS/CC composite endows it with abundant catalytically active sites, thereby accelerating the reduction of I₃^-. More importantly, the dye-sensitized solar cells (DSSCs) prepared by scraping it on flexible titanium mesh with low resistance had low series resistance (R_s). Electrochemical characterizations revealed that the DSSCs employing the FMS/CC counter electrode achieved a power conversion efficiency (PCE) of ca. 9.51% (surpassing the ca. 8.15% efficiency of the Pt counter electrode), open-circuit voltage (V_oc) of ca. 0.79 V, short-circuit current density (J_sc) of ca. 18.31 mA·cm^-2, and fill factor (FF) of ca. 0.65. Moreover, after 100 times of cyclic voltammetry (CV) test, the CV curve remainedunchanged, indicating the excellent stability of FMS/CC in the electrolyte containing I^3-/I^-.
