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。

通过微波加热方式，快速合成了3个葡萄糖修饰的双席夫碱。通过比浊度分析、HRP/Amplex Red实验、DCFH-DA荧光探针实验、NBT分析法以及MTT实验检测它们抑制金属离子诱导的Aβ聚集、减少活性氧(ROS)生成及抑制Aβ聚集产生的细胞毒性。发现葡萄糖修饰的双席夫碱都能有效抑制金属离子(Zn²⁺、Cu²⁺)诱导的Aβ_1~40的聚集，降低Cu²⁺-Aβ加合物催化产生ROS水平、提高Cu²⁺-Aβ作用的细胞内超氧化物歧化酶的活力，有效抑制Zn²⁺或Cu²⁺诱导Aβ聚集而产生的神经细胞毒性并大幅提高细胞存活率。作为对比，我们也检测了相同条件下的氯碘羟喹(cliquinol, CQ)和没有葡萄糖修饰的同类双席夫碱的活性，发现葡萄糖修饰的双席夫碱各方面活性均好于CQ；葡萄糖修饰的双席夫碱自身毒性小、抗氧化和提高Aβ与金属离子共同处理的细胞的存活率方面均优于未葡萄糖官能化的同类双席夫碱。

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^-.
