Summary: In this study, a Mg alloy with alloying elements of Zn, Al, Sn, and Mn was designed, and hot extrusion was carried out at various speeds and temperatures. It was found that high speed extrusion resulted in more second phase particles, while high extrusion temperature increased the number of second phases, grain size, and dynamic recrystallization degree. The sample extruded at a speed of 10 mm/min and temperature of 300 degrees C showed the highest yield strength, tensile strength, and corrosion resistance.

Summary: Ultrahigh-strength Mg-9.2Gd-4.4Y-1.0Zn-0.8Mn (wt%) alloys were produced through isothermal ageing, resulting in a microstructure characterized by bimodal a-Mg grains and prismatic b' and basal g' phases precipitated during ageing. The peak-aged alloys exhibited the highest tensile strength, with satisfactory ductility, due to dense number distribution co-precipitation that increased critical resolved shear stresses and inhibited microcrack nucleation and propagation. These findings have significant implications for high-strength Mg-Gd-Y-Zn alloys in practical applications.

Summary: The volume fraction and distribution of long-period stacking ordered (LPSO) phase have a significant impact on the strengthening of Mg alloys. The LPSO phase formed at grain boundary has a higher strengthening effect than that formed within the alpha-Mg matrix, but it compromises the solid-solution strengthening effect due to the consumption of alloying elements.

Summary: The effects of Ca addition on the microstructure and mechanical properties of Mg-Zn-Sn-Mn alloys were investigated. With increasing Ca content, the eutectic phase and grains were refined, and the morphologies of the CaMgSn phases changed. Small amounts of Ca can improve properties at room temperature. However, increasing Ca content results in the deterioration of alloy properties. A small amount of Ca can improve the high-temperature plasticity.

Summary: A high-strength Mg-based alloy bar was successfully fabricated by extrusion and two-step aging processes. The extent of extrusion was found to affect the refinement mechanisms of the alloy, with larger extents leading to finer grains and eutectic phases. Peak-aged treatment resulted in increased strength due to the presence of beta' phase and LPSO phase. Over-aging led to reduced performance as lamellar precipitates and spherical beta' phase increased in size.

Summary: The MgAl Layered double hydroxides (LDHs)/graphene oxide (GO) composite film was synthesized in situ on the micro-arc oxidation (MAO) film of AZ31 magnesium alloy using hydrothermal chemical conversion method. The growth behavior and corrosion properties of the composite film were investigated. The results showed that the composition and morphology of the composite film changed gradually with the extended hydrothermal treatment time, utilizing the self-dissolved cation in the MAO film as the LDHs source. The MAO/LG-12 h coating exhibited higher corrosion resistance (1.28 x 10-9 A/cm2) compared to the MAO coating (8.49 x 10-6 A/cm2), thanks to the synergistic effect of GO and LDHs.

The monolayer C12-3-3 exhibits high specific capacities for Li and Mg, surpassing most previous anodes. The 2D carbon material of C12-3-3 also demonstrates rapid diffusion kinetics, making it a promising choice for high-capacity and high-rate performance batteries.

Summary: A highly homogeneous fine-grained Mg-3Al-1Zn (AZ31) alloy was successfully fabricated using a simple extrusion method called pre-die forging extrusion (PFE). The strain induced by the pre-forging process led to crystal defects and a higher driving force for dynamic recrystallization. By using PFE for 60 s at 300 degrees C (300-60 s), the grain size of the AZ31 alloy was significantly refined to 1.74 mu m. The 300-60 s samples exhibited excellent mechanical properties with a tensile yield strength of 305 MPa and an elongation of 27%. The improvement in the mechanical properties of the PFE samples is mainly attributed to the grain refinement mechanism. This study provides an experimental basis for determining the appropriate temperature to refine the grains during extrusion.

Summary: In the pursuit of high-energy-density lithium-ion batteries, the safety issues of batteries have become apparent. To address this, a new flame-retardant separator has been developed to enhance the safety performance of lithium-ion batteries. The flame-retardant separator utilizes nitrogen-phosphorus synergistic effect to dilute noncombustible gas and rapidly suppress thermal runaway. Experimental results show that the developed separator exhibits negligible shrinkage at 200 degrees C and extinguishes flames in just 0.54 seconds, surpassing commercial separators. Moreover, pouch cells have been assembled to validate the safety performance of PVDF-HFP/MPP separators.

Summary: The study investigates the influence of Ca on the thermal expansion and mechanical properties of Mg. It is found that alloying Ca can significantly decrease the coefficient of thermal expansion (CTE) and increase the strength of Mg. The low CTE and high compressive yield strength achieved in Mg-Ca alloys are closely related to the increased precipitation of Mg2Ca phase, which has high melting point, elastic/shear moduli and low CTE. The increased fraction of the eutectic lamellar structure consisting of Mg2Ca and a-Mg also contributes to the noticeable increase of strength in the as-cast Mg-Ca alloys.

Summary: This study aims to explore the relationship between the texture and tensile properties of the AZ31 Mg alloy using machine learning. Texture characteristic parameters such as maximum pole intensity (Imax), texture dispersion (D), and texture directivities along the longitudinal direction (PLD) and transverse direction (PTD) are extracted from the (0002) pole figures. An artificial neural network (ANN) model is constructed and trained using data from literature to describe the relationship between texture characteristics and tensile properties. The ANN model shows good predictive performance in yield strength and elongation of the AZ31 Mg alloy when applied to new cases. The correlations between texture characteristics and tensile properties are analyzed based on the ANN-predicted results.

Summary: Due to their high safety, low cost, and environmental friendliness, aqueous rechargeable Mg-ion batteries (ARMIBs) have attracted extensive attention as future energy storage systems. However, the poor migration kinetics of Mg2+ during intercalation/extraction still limits the development of suitable cathode materials. In this study, a layered buserite Mg-Mn oxide (MMO) with a large interlayer space and low-crystalline structure was found to enhance the Mg2+ migration kinetics. The MMO cathode exhibited high Mg storage capacity, excellent rate capability, and fast Mg2+ migration in the aqueous electrolyte.
