源起于发霉甜苜蓿，脱胎于生化实验室，华法林先生起初作为一种强力灭鼠毒药大杀四方。然而，在进入医药领域的道路上，他却因毒药的身份标签和种种流言而饱受质疑和反对。科学家们揭示了华法林抗凝血的机制，并证明了华法林抗凝治疗对患者的益处。从此，华法林先生以及他的衍生物们成为了抗凝治疗和防治鼠害的前线战士。

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.
