Summary: This paper discusses the preparation process, microstructure, hardness, wear resistance, and corrosion resistance of high-entropy alloy films, and analyzes the influence of factors such as nitridation, sputtering power, substrate temperature, and substrate bias on the phase structure of alloy films. High-entropy alloy films can be prepared using various processes. They tend to form a solid solution and amorphous state, and their hardness is much higher than that of traditional films. Some high-entropy alloy films have better corrosion resistance than stainless steel due to the corrosion-resistant elements and amorphous structure. High-entropy alloy films have promising development prospects in wear-resistant coatings, corrosion protection, diffusion barriers, and photothermal conversion coatings.

Summary: Zinc aluminum-layered double hydroxide (ZnAl-LDH) was grown in-situ on the low-pressure cold gas spraying (LPCGS) Al coating by hydrothermal method. The composite coating zinc aluminum-layered double hydroxide-Graphene oxide (LDH-G) was formed by electrostatic adsorption of graphene oxide (GO) and ZnAlLDH. LDH-G coating showed excellent reduction in wear and corrosion resistance, attributed to the good mechanical properties of graphene and the corrosion inhibition effect of ZnAl-LDH.

Summary: The laser cladding method is an effective approach to improve the surface properties of Mg and Mg alloys by preparing amorphous matrix composite coatings. The corrosion and wear resistance of these coatings are significantly influenced by rare earth elements, which affect the quantity, morphology, and distribution of crystalline phases. The presented work focused on preparing Zr55Cu30Al10Ni5 + x wt% Nd2O3 (x = 0, 0.5, 1, 1.5, 2, 3) composite coatings on AZ91D Mg alloy through laser cladding. The coatings consisted of dendrites, cellular grains, Nd enriched spherical structure, and amorphous matrix. Addition of appropriate Nd2O3 could refine crystalline microstructure size, purify oxygen impurities, and increase amorphous content, but excessive addition caused aggregation and abnormal growth of crystalline phases, deteriorating the glass forming ability. The coating with 1.5 wt% Nd2O3 exhibited the highest amorphous content, lowest crystalline phase content, and the most excellent corrosion resistance. The wear resistance of the coatings was greatly improved compared to the Mg substrate, but not linearly related to hardness and did not fully follow Archard's wear equation.

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 electrochemical performance of MLIBs was greatly enhanced compared to MIBs, and the energy storage mechanism involved Mg2+ intercalation in MIBs and Mg2+/Li+ co-intercalation in MLIBs. This research further explores the energy storage mechanism of MLIBs and lays the theoretical foundation for the development of high-performance cathode materials.

In this study, we identify that the monolayer C12-3-3 in sp2-sp3 carbon hybridization with high Li/Mg affinity is a suitable anode material for Li-ion batteries and Mg-ion batteries. 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: 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: Graphene oxide (GO) lamellar membranes suffer from low flux and poor stability for practical applications due to tortuous transport pathways and weak interlamellar interactions. In this study, porous vermiculite (PVMT) nanosheets were incorporated into the GO-based membranes to establish fast and robust water-selective pathways. PVMT nanosheets provided in-plane pores, reducing the tortuosity and mass transport distance. The hydrophilicity and interlayer distance were enhanced by PVMT nanosheets, contributing to water-selective transport. The resulting membranes exhibited excellent dehydration performance with increased permeation flux and separation factor compared to pristine GO/PTFE membranes, while maintaining stability for 192 h operation. This study may inspire further research in constructing mass-transfer pathways within lamellar membranes.
