Summary: Sodium metal batteries, with the advantages of high theoretical capacity, low cost and wide availability, have great potential in electric vehicles and grid-scale energy storage. However, achieving stable cycling of sodium metal anodes remains a challenge due to low Coulombic efficiency caused by side reactions. A g-C3N4 layer was attached to the Ti3C2 MXene surface, forming a stable hetero-interphase and inhibiting side reactions. The 3D Ti3C2 MXene@g-C3N4 nanocomposite showed enhanced Coulombic efficiency, long-term stability, and outstanding rate capability for sodium metal anodes.

Summary: Due to the abundance and cost effectiveness of sodium, rechargeable sodium metal batteries have attracted widespread attention as a potential replacement for lithium-ion batteries. However, challenges such as the reactivity of sodium, unstable solid-electrolyte interphase (SEI), and sodium dendrite formation remain unresolved. This study investigates the mechanistic behavior of sodium metal plating using operando X-ray and optical imaging techniques. The addition of a fluorine-containing additive to the electrolyte results in more uniform sodium plating and enhanced cycling performance due to the formation of a stable SEI containing NaF.

Summary: This study demonstrates a novel approach to enhance the electrocatalytic activity for HER by coating FeP nanorod arrays (FeP NRAs) with polypyrrole (PPy) on carbon textiles (CTs). The PPy coating decreases the activation energy for HER and increases the turnover frequency of catalysts, leading to significantly improved electrocatalytic performance. This research has important implications for cost-effective non-noble-metal HER catalysts in large-scale hydrogen fuel production.

Summary: The slow diffusion of Na ions compared to Li ions in sodium-ion batteries is due to the relatively large ionic radius of the Na ion. Interlayer expansion through intercalation of guest ions is an effective technique for facilitating Na-ion diffusion. This study explores the role of different alkali-metal ions in intercalated layered titanate and finds that Na intercalated layered titanate demonstrates superior performance due to high alkaline metal ion concentration and efficient utilization of active sites.

Summary: Geogrid pullout tests were conducted to analyze the reinforcement influence zone and soil particle displacement field. Factors affecting the formation speed of the reinforcement influence zone, gradient layer thickness, and particle displacement characteristics were discussed. The study showed that the reinforcement influence zone's form and displacement direction remain unchanged with pullout displacement, and the normal load, geogrid type, and coarse grain content affect the formation speed and thickness of the gradient layers.

Summary: A heterogeneous seed layer of Au nanoparticles (NPs) is deposited on 3D porous vertical graphene nanosheets on carbon cloth (Au-VG/CC) to create a lithiophilic surface, resulting in a smooth and dendrite-free morphology. The Au-VG/CC electrode shows a small voltage hysteresis (67.2 mV) and long cycling life (more than 500 h) at a high current density of 5 mA cm-2 with 5 mAh cm-2. XRD and in-situ transmission electron microscopy reveal a lithiophilic layer of Li3Au, which guides lithium deposition. Furthermore, a full battery assembled with Li@Au-VG/CC anode and LiFePO4 cathode exhibits a capacity of 77.3 mAh g-1 at 100 mA g-1 after 200 cycles.

Summary: To accurately measure the dynamic deflection of bridges, we propose a reference point-free measurement system consisting of a level sensor and an accelerometer. The level sensor measures the low-frequency deflection components, while the accelerometer measures the high-frequency deflection components. Through signal fusion algorithm, the absolute dynamic deflection and key parameters can be obtained. Laboratory and field tests show that the system can achieve continuous high-precision deflection measurements of bridges under traffic flow.

Summary: In recent years, wildfires have frequently caused transmission line tripping in mountain areas. To understand the mechanism of these events, an experimental system using a simulated fire source was designed to study the breakdown discharge processes of model wires. The experiment explored the breakdown behaviors and characteristics of two ACSR segments in propane flames with three different flame zones, considering different gas flow rates and wire-wire gaps. The results showed that the breakdown voltages increased linearly with increasing wire-wire gaps, and short wire-wire gaps were more likely to form pilot discharge channels under lower voltages and weaker ionization environments.
