Aqueous zinc batteries offer significant potential for large-scale energy storage, wearable devices, and medium-to low-speed transportation due to their safety, affordability, and environmental friendliness. However, the uneven zinc deposition at the anode side caused by localized reaction activity from the passivation layer presents challenges that significantly impact the battery's stability and lifespan. In this study, we have proposed an expandable and maneuverable gel sustained-release (GSR) treatment to polish the Zn metal, which in situ converts its native passivation layer into a composite interphase layer with nanocrystal zinc phosphate and flexible polyvinyl alcohol. Such a thin and uniform interface contributes to fast and homogeneous Zn ion transport and improved anti-corrosion ability, enabling uniform zinc deposition without dendrite growth and thereby improving the battery performance with high-rate ability and long cycle life. This GSR treatment method, characterized by its simplicity, low cost, and universality, facilitates the widespread application of aqueous zinc batteries. © 2025 Institute of Process Engineering, Chinese Academy of Sciences

Unveiling the Mo Effect on the Interfacial Characteristics and Microstructure Stability of γ′-phase Strengthened Co-Based Superalloys

The effects of Mo on the interface characteristics and coarsening behavior of the γ′-phase in Co-based superalloys were analyzed comprehensively. The addition of Mo had significant impacts on the morphology, misfit and microstructural stability of the γ′-phase during thermal exposure. Results showed that Mo occupies the B sublattice sites in the γ′-phase, sharing with Al and W, thus increasing the volume fraction and solvus temperature. Mo weakened the partitioning behavior of solutes between the γ-matrix and γ′-phases, leading to decreased misfit. During thermal exposure, the misfit of all three alloys increased continuously. Through quantification and statistics, the misfits of approximately 0.5% yielded optimal γ′ morphology for Co-based superalloys. Mo segregated at the interface and increased the interface width, lowering the interfacial energy and effectively reducing the coarsening rate of the γ′-phase. More advanced coarsening kinetics studies revealed a transition from initial matrix-diffusion controlled coarsening to interface-reaction controlled coarsening during thermal exposure of the γ′-phase, Mo prolonged the matrix-diffusion controlled and delayed the transition to interface-reaction controlled. This work offers important insights that will inform future alloy design and heat treatment strategies to optimize the high-temperature structural performance of γ′ strengthened Co-based superalloys. © 2023, The Authors.

An advanced Approach to Improve the High-Temperature Property for Ni-Based Superalloys: Interface Segregation Manipulation

In response to the requirements for the long-term service reliability of Ni-based superalloys, the correlation between the microstructure and creep property are investigated in present work. Creep experiments were conducted on a designed Ni-based single crystal superalloy at 900°C/330MPa, the results showed that the creep rupture property decreased after thermal exposure at both 900°C and 1000°C. The γ′-phase, γ-matrix and γ/γ′ interface undergo different degrees of degradation, including the coarsening and the decrease in the volume fraction of γ′-phase, the decrease in the γ-matrix strength, the decrease in the lattice misfit and the increase in the dislocation network spacings. When the values of microstructural parameters (γ′-phase size and volume fraction) were numerically close at 900°C and 1000°C for different thermal exposure time, like 900°C/10,000h and 1000°C/2000h samples. The experimental alloy exhibits better creep property for thermal exposure at 1000°C than that at 900°C. By combining atom probe tomography and first-principles calculations, an interface strengthening mechanism driven by interface segregation is identified. Finally, a design concept for high-strength metal alloys based on the decoration of solutes interface segregation is proposed, also called "Interface Segregation Manipulation". © 2023, The Authors.

Steel ring reinforcement technology is an effective method to eliminate the damage of tunnel structure caused by ground load, surrounding foundation pit and underground water source. The grouting material used to fill the gap between the tunnel segment and the steel ring should have the characteristics of low viscosity, high strength, rapid curing at room temperature and anti-subway vibration. In this work, a special polyurethane modified epoxy resin grouting was fabricated to overcome the inherent brittleness of epoxy resin, and was combined with the reactive diluent and the amine curing agent to suit the above applications. The results showed that both tensile and impact strength of epoxy resin grouting modified by polyurethane were improved obviously compared with those without modification, presenting an obvious toughening effect. Although the viscosity increased slightly, it can still meet the perfusion requirements of steel ring reinforcement of subway tunnels. © Published under licence by IOP Publishing Ltd.

In this paper, cables with metallized coated aramid shielding materials are prepared, and the time-domain shielding effectiveness of different structures are analyzed in comparison with those of traditional shielding cables. The results show that the time-domain shielding effectiveness inside the cable with metallization-coated aramid fibers as the shielding layer can be increased by 65% compared to the cable with traditional shielding materials. The results indicate that the metallized coated aramid material has superior shielding ability, which provides more reliable technical support for its application in the field of electromagnetic compatibility and promotes the stable operation and development of electronic equipment and communication systems.
