Summary: Employing lithium-rich layered oxide (LLO) as the cathode in all-solid-state batteries (ASSBs) is desired for high energy density, but its poor kinetics due to low electronic conductivity and oxygen-redox-induced structural degradation hinders its application. This study enhances the charge transfer kinetics of LLO by constructing efficient electron transport networks within solid-state electrodes, reducing electron transfer resistance, and stabilizes the lattice oxygen of LLO through an infusion-plus-coating strategy, suppressing interfacial oxidation and structural degradation. The LLO-based ASSBs exhibit high discharge capacity and long cycle stability, providing important insights for the development of high-energy-density ASSBs.

Summary: A critical modification of pre-intercalating metal ions in the MnO2 interlayer is reported to modulate the H+ intercalation behavior in aqueous zinc ion batteries. By optimizing the metal-O bond type and covalency degree, the p-band center of O (epsilon(p)) can be effectively tuned to promote the balance between H+ adsorption and desorption, resulting in enhanced rate capability. This work highlights the significance of epsilon(p) as a descriptor for H+ intercalation in ZIBs.

Summary: This paper proposes an effective strategy of nanoconfinement in a 3D conductive matrix to solve the challenges of FeF3, including low conductivity, sluggish reaction kinetics, and side reactions. The nanoconfined FeF3 nanoparticles are only 10-50 nm. The composite has a high loading of 81.89%, the highest among previous composites reported. The prepared FeF3-carbon nanofiber composites show high reversible capacities of up to 313 mAh g(-1) at 0.1 C, and enhanced cycle stability of 88.4% after 100 cycles at 1 C. The improved performance is attributed to the 3D conductive network and the nanoconfinement of FeF3, which facilitate electron transport and shorten the ion transport path. This work provides an effective strategy to enhance the electrochemical performance of conversion-typed metal fluoride cathodes for LIBs.

Summary: We systematically investigated the optical and magnetic properties of Ru-doped hybrid improper perovskite Ca3Mn2O7. Ru doping enhanced the ferromagnetism of Ca3Mn2O7 and quasi-2D antiferromagnetic fluctuation effect was observed in certain doped samples. The optical bandgaps of the doped samples were reduced and distortion of the Mn-O bonds was observed. The Ru-doped materials with the coexistence of ferromagnetic and antiferromagnetic orderings are expected to be excellent candidates for magnetoelectric devices.

Summary: Regulating the energy barrier of *COOH is crucial for the rate determining step in the photocatalytic reduction of CO2 to produce CO gas. In this study, an appropriate Zn vacancy on ZnIn2S4 was synthesized to enhance the photocatalytic CO2 reduction capacity (CO: 5.63 mmol g(-1) h(-1)) and selectivity (CO: 97.9%). Different sulfhydryl groups were used to regulate the formation of Zn vacancies in ZnIn2S4, leading to the generation of unsaturated sulfur coordination state adjacent to the Zn vacancy with fewer electrons compared to ZnIn2S4 without Zn vacancy. Experimental analysis and theoretical calculations demonstrated that the appropriate Zn vacancy shifted the Gibbs free energy of *COOH from endothermic to exothermic during the photoreduction of CO2. This work provides an engineering method to optimize cation vacancies and improve the efficiency of photocatalytic CO2 reduction by adjusting the energy barrier of intermediates.

Summary: Hot-stamping steel is a high-strength steel used in key safety components of vehicles. It can be produced using traditional or compact strip production (CSP) processes. The microstructure, mechanical properties, and corrosion behavior of hot-stamping steel produced by these processes were compared. The CSP process resulted in a slightly better corrosion resistance due to smaller inclusion size and distribution density, reducing the number of corrosion sites.

Summary: This review provides a systematic study of the relationship between multi-scale microstructural tailoring and the mechanical behavior and other service performance of high-strength press-hardened steels (PHS). Traditional Mn-B steels and novel PHS are categorized into different strategies to enhance their properties. The addition of microalloying elements in traditional Mn-B steels refines the microstructure of PHS, resulting in improved mechanical properties and hydrogen embrittlement resistance. On the other hand, novel PHS with innovative thermomechanical processing obtains a multi-phase structure and superior mechanical properties compared to traditional Mn-B steels, while also affecting oxidation resistance.

Summary: In this study, it was discovered that the mechanical properties of TiZrHfNb high-entropy alloys can greatly vary with the impurity content in the samples, even when using high-purity raw materials. Oxygen impurity mainly increases the yield stress through strong interstitial hardening, while the deterioration of ductility is closely associated with the content of metalloid elements B, C, and Si. The analysis revealed that these metalloid elements tend to segregate at grain boundaries and enhance the aggregation of Zr and Ti, leading to grain boundary embrittlement and brittle fracture. This study demonstrates the importance of strict control over impurity contents in refractory high-entropy alloys during production to improve their mechanical performance stability.

Summary: In this study, the microstructures and mechanical properties of interphase precipitation strengthening micro-alloyed steels were investigated. The addition of Cr was found to increase the yield strength without significant decrease of ductility. Thermodynamics analysis revealed that the addition of Cr led to grain refinement and decrease of sheet spacing of nanoprecipitates. Calculations showed that the decrease of interphase-precipitated carbides sheet spacing and the refinement of grain size were responsible for the strength enhancement of Cr microalloyed steel.
