The high sensitivity, tunable chemical compositions, electronic dimensions, and low-cost raw materials make perovskites promising next-generation semiconductors. However, their ionic nature brings serious concerns about their chemical and water stability, limiting their applications in well-established technologies like crystal polishing, micro-processing, photolithography, etc. Herein we report a one-dimensional tryptamine lead iodide perovskite, which is stable in water for several months as the strong cation-π interactions between organic cations. The one-dimensional and two-dimensional tryptamine lead iodide perovskite tablets are switchable through thermal-annealing or water-soaking treatments to relax microstrains. The water-stable and microstrain-free one-dimensional perovskite tablets yield a large sensitivity of 2.5 × 10⁶ μC Gy_air^-1 cm^-2 with the lowest detectable dose rate of 5 nGy_air s^-1. Microelectrode arrays are realized by surface photolithography to construct high-performance X-ray flat mini-panels with good X-ray imaging capability, and a record spatial resolution of 17.2 lp mm^-1 is demonstrated.23:T4a6,Recently, with the increasing integration of wind power into power systems through power electronic converters, new types of subsynchronous resonance/oscillation (SSR/SSO) occurred frequently. The most striking feature is the participation of the converter control. It has been demonstrated that converter control had a decisive impact on the forming of oscillation at the wind farms in the Guyuan and Hami systems, China. Obviously, the mechanism and characteristics of these new phenomena are different from those of traditional SSR/SSO defined by IEEE. Theoretical research in this area is still at its initial stage. To promote the studies of these emerging SSR/SSO issues, it is necessary to improve the classification of SSR/SSO. In this paper, the evolution and existing classification of SSR/SSO are reviewed at first. Then, a new classification is proposed based on the dominant source of oscillatory modes and the way of interaction between generators and the grid. Next, several actual SSR/SSO incidents caused by the interactions between wind generators and the AC grid are discussed. Finally, the co‐existence of and interaction among different types of SSR/SSO are revealed.24:T4a1,A potentiometric sensor based on YSZ and NiFe2O4 sensing electrode was developed for CO detection. NiFe2O4 was prepared by sol-gel method and calcined at 900°C for 6 h. NiFe2O4-SE was prepared by screen printing and sintered at 1150°C for 3 h. NiFe2O4 powder and NiFe2O4-SE were confirmed to be pure phase after XRD characterization. The SE presents a porous network structure based on SEM analysis. The CO response characteristics of the sensor were evaluated between 650°C and 750°C, and it was found that it had the largest sensitivity with the slope of −47.57 mV/decade at 700°C and could detect a minimum CO concentration of 20 ppm. At 700°C, the sensor had relatively short response and recovery times of 21 s and 52 s for 320 ppm CO, respectively. The response values varied almost linearly with the logarithm of CO concentration at each operating temperature, which is consistent with mixed-potential mechanism verified by polarization curves. It showed tiny cross sensitivi
