The target of this paper is studying the quasi-synchronization problems of the heterogeneous Lur'e networks with impulsive feedback control. By introducing impulsive feedback control, the heterogeneous Lur'e network is analyzed. The sufficient condition for guaranteeing quasi-synchronization is derived by means of linear matrix inequality(LMI), the Schur complement and the principle of comparison. More over, the upper bound of exponential quasi-synchronization errors is further calculated. Finally, the numerical simulations are presented to illustrate the effectiveness of the control protocol and theoretical results.

In order to meet the needs of aircraft multi-electric development, an electric drive emergency release system was designed for the upper gear lock mechanism of a certain type of aircraft landing gear. Firstly, the mechanical equilibrium equation of the upper lock mechanism was established and theoretical analysis was carried out. Based on LMS Virtual. Lab/Motion and AMESim software, the dynamic models of the emergency lock release system of the landing gear and the electric drive system under different braking modes were established respectively, and the joint simulation was further realized. Finally, the effect of different braking modes on electric drive emergency release system was discussed in detail. The results show that the electric drive actuator of the short-circuit brake system, where the brushless DC motor drives the ball screw to unlock the upper lock and realizes the emergency unlock function, possesses the best driving effect. The analysis results provide theoretical support for the design of electric drive actuators of aircraft landing gear emergency system. © 2019, Springer Nature Singapore Pte Ltd.

A double moirésuperlattice can be realized by stacking three layers of atomically thin two-dimensional materials with designer interlayer twisting or lattice mismatches. In this novel structure, atomic reconstruction of constituent layers could introduce significant modifications to the lattice symmetry and electronic structure at small twist angles. Here, we employ conductive atomic force microscopy (cAFM) to investigate symmetry breaking and local electrical properties in twisted trilayer graphene. We observe clear double moirésuperlattices with two distinct moiré periods all over the sample. At neighboring domains of the large moiré, the current exhibit either two- or six-fold rotational symmetry, indicating delicate symmetry breaking beyond the rigid model. Moreover, an anomalous current appears at the ‘A-A’ stacking site of the larger moiré, contradictory to previous observations on twisted bilayer graphene. Both behaviors can be understood by atomic reconstruction, and we also show that the cAFM signal of twisted graphene samples is dominated by the tip-graphene contact resistance that maps the local work function of twisted graphene and the metallic tip qualitatively. Our results unveil cAFM is an effective probe for visualizing atomic reconstruction and symmetry breaking in novel moirésuperlattices, which could provide new insights for exploring and manipulating more exotic quantum states based on twisted van der Waals heterostructures. © 2022, CC BY.

Challenges in directly regulating reaction pathways in small molecules electrooxidation have hindered widespread applications. Hence, we report directly tuning the pathway of formic acid oxidation (FAO) through the integration of theoretical and experimental approaches. DFT calculations indicate that the Pt1Co1 alloy with 50% Co incorporation is an ideal candidate for HCOO* formation with a significantly lower Gibbs free energy (−0.296 eV) compared to that of COOH* (0.028 eV), which reverses the trend on Pt. Guided by theoretical predictions, we fabricate bimetallic PtCo alloys using an eco-friendly microwave method. The Pt1Co1 alloy exhibits a 121-fold increased activity (1.18 A mgPt−1) compared to Pt. In situ infrared spectra confirm that PtCo alloys catalyze FAO through the direct pathway, suggesting a crucial role of Co in enhancing Pt's resistance to CO poisoning, perfectly aligning with the predicted changes. This work provides an essential reference for the rational development of high-efficiency Pt-based alloy electrocatalysts. © 2024, The Authors. All rights reserved.

The quest for quantum materials with diverse symmetry-protected topological states has been the focus of recent research interest, primarily due to their fascinating physical properties and the potential technological utility. In this work, we report on the magnetotransport, de Haas-van Alphen (dHvA) oscillations, and the first-principles calculations of the stannide Cu3Sn that is isostructural with the recently reported topological semimetal Ag3Sn. The magnetoresistance was found to vary quasi-linearly in field. Clear dHvA oscillations were observed under a field as low as 1 Tesla at 2 K, with three major oscillation frequencies Fα=8.74 T, Fβ=150.19 T and Fγ=229.66 T and extremely small effective masses. The analysis of dHvA quantum oscillations revealed a possible nonzero Berry phase, suggestive of the nontrivial band topology. The corroborating evidence for the nontrivial electronic topology also comes from the first-principles calculations which yield a nonzero 2 topological index. These results collectively suggest that Cu3Sn, in analogy to its homologue Ag3Sn, may be another intermetallic stannide hosting topological Dirac fermions. Copyright © 2022, The Authors.
