Summary: Surface strain engineering is a promising strategy for designing electrocatalysts for sustainable energy storage and conversion. This study presents the preparation of a trifunctional electrocatalyst (Ru/RuO2@NCS) by anchoring lattice mismatch strained core/shell Ru/RuO2 nanocrystals on nitrogen-doped carbon nanosheets. The resulting catalyst exhibits high catalytic activity for the oxygen evolution reaction (OER), oxygen reduction reaction (ORR), and hydrogen evolution reaction (HER), enabling high power and energy density in rechargeable Zn-air batteries and achieving efficient water splitting. The compressive strained RuO2 in the catalyst reduces the reaction barrier and improves the binding of intermediates, leading to enhanced catalytic activity and stability.

Summary: The high energy density of rechargeable metal batteries has attracted much interest, but their poor cycle stability and low Coulomb efficiency restrict commercialization. Adding small doses of additives to the electrolyte is a simple and effective strategy to address these problems. Multifunctional additives that improve metal deposition and cyclability are necessary for high-performance metal batteries. This review focuses on recent developments in multifunctional additives for stable and dendrite-free Li/Na/Zn anodes, as well as challenges and perspectives in optimizing electrolyte formulation.

Summary: In this paper, a functionalized separator composed of nitrided niobium dioxide (n-NbO2) and polypropylene (PP) is reported, which improves the electrochemical stability of lithium metal batteries (LMBs). Niobium oxide interacts with metallic lithium, resulting in the redistribution of localized lithium ions. The nNbO2-coated separator with enhanced electrical conductivity promotes the lithium plating/stripping process and reinforces the redistribution effect of lithium ions. Thus, lithium-copper (Li-Cu) cells with the n-NbO2-coated separator exhibit excellent cycle stability and high Coulombic efficiency (CE) over 200 cycles.

Summary: Fire safety is crucial for the development of efficient and safe energy systems for space objects. This paper focuses on studying the influence of gravity on combustion processes and analyzes the dynamics of inverted conical methane-air flame under external acoustic excitation. The results show that at high excitation frequencies, the intensity of vortex generation is similar to that observed in experiments with normal gravity, indicating the dominance of acoustic mechanism. Additionally, at an external excitation frequency of 240 Hz, significant growth in shear vortex diameters and increased amplitude of perpendicular oscillations of flame branches were observed, indicating the most intensive large scale instability of flow.

Summary: This study investigates the influence of deployment friction on the dynamic characteristics of nonconductive space tether through experimental measurement and numerical simulation. The results show that deployment friction significantly limits the uncontrolled tether deployment, while increasing the initial deployment velocity and satellite effective mass, as well as decreasing orbital altitude, can enhance the deployment capability and dynamic stability. In addition, an optimal matching relationship between tether length and satellite total mass is proposed, which is of substantial importance for the design of nonconductive space tether systems.
