利用甘氨酸-硝酸盐方法合成LaNi_(0.6)Fe_(0.4)O_(3-δ)(LNF)粉末,采用LNF多孔主干熔渗法制备掺杂二氧化铈LNF-钆(GDC)固体氧化燃料电池纳米复合阴极。研究了LNF-GDC纳米复合阴极的电化学性能和铬中毒行为。当甘氨酸和硝酸盐的摩尔比为1:1时可得到单相钙钛矿LNF。与LNF相比,LNF-GDC纳米复合阴极的极化阻抗显著降低,这与增强的催化活性和增大的三相边界长度有关。另外,在开路条件下,纳米复合阴极有较好的铬容限。在中温固体氧化燃料电池中,LNF-GDC纳米复合阴极有望成为一种颇具潜力的阴极材料。

Urban rail transit (URT) disruptions present considerable challenges due to several factors: i) a high probability of occurrence, arising from facility failures, disasters, and vandalism;ii) substantial negative effects, notably the delay of numerous passengers;iii) an escalating frequency, attributable to the gradual aging of facilities;and iv) severe penalties, including substantial fines for abnormal operation. This article systematically reviews URT disruption management literature from the past decade, categorizing it into pre-disruption and post-disruption measures. The pre-disruption research focuses on reducing the effects of disruptions through network analysis, passenger behavior analysis, resource allocation for protection and backup, and enhancing system resilience. Conversely, post-disruption research concentrates on restoring normal operations through train rescheduling and bus bridging services. The review reveals that while post-disruption strategies are thoroughly explored, pre-disruption research is predominantly analytical, with a scarcity of practical pre-emptive solutions. Moreover, future research should focus more on increasing the interchangeability of transport modes, reinforcing redundancy relationships between URT lines, and innovating post-disruption strategies.

Precision measurement of magnetic fields is a crucial issue in both fundamental scientific research and practical sensing technology. The sensitive detection of a vector magnetic field poses a significant challenge in quantum magnetometry, particularly in estimating a vector DC magnetic field with high precision. Here, we propose a comprehensive protocol for quantum vector DC magnetometry, utilizing selective phase accumulation in both non-entangled and entangled quantum probes. Building upon the principles of Ramsey interferometry, our protocol enables the selective accumulation of phase for a specific magnetic field component by incorporating a meticulously designed pulse sequence. In the individual measurement scheme, we employ three individual quantum interferometries to independently estimate each of the three magnetic field components. Alternatively, in the simultaneous measurement scheme, the application of a pulse sequence along different directions enables the simultaneous estimation of all three magnetic field components using only one quantum interferometry. Notably, by employing an entangled state(such as the Greenberger-Horne-Zeilinger state) as the input state, the measurement precisions of all three components may reach the Heisenberg limit. This study not only establishes a general protocol for measuring vector magnetic fields using quantum probes, but also presents a viable pathway for achieving entanglement-enhanced multi-parameter estimation.
