Summary: Magnesium ion batteries have gained considerable attention due to their high theoretical specific capacity and the abundance of magnesium resources. However, using pure magnesium as anode material leads to slow kinetics of magnesiation/demagnesiation due to the formation of a passive film at the electrolyte-anode interface. This study investigated the electrochemical properties of bismuth-antimony-tin alloy anodes for magnesium ion batteries and found that the substitution of tin for magnesium improved the demagnesiation activity. The formed multi-phase structure and multi-step phase transition process in the alloy anodes were beneficial for the transport kinetics of magnesium ions, resulting in enhanced cycling stability and rate performance.

Summary: ZK60 magnesium alloy was treated with laser shock peening at different laser energy densities and then fretting corrosion wear tests were conducted on the treated and untreated samples. The relationships between microstructure, residual stress, surface hardness, tensile strength, corrosion resistance, and fretting corrosion wear behavior were analyzed. Results showed that laser shock peening treatment can reduce fretting corrosion wear volume by up to 73.4%. The improvement in surface hardness, tensile strength, and corrosion resistance due to fine grain strengthening, dislocation and twinning-induced strain hardening, and compressive residual stress contribute to the reduction of fretting corrosion wear.

Summary: The effect of Y2O3 addition on the microstructure and properties of laser cladded Al-Si alloy coating on AZ91D magnesium alloy surface was investigated. The experimental results showed that the cladding layers with Al-Si + Y2O3 contained alpha-Mg, Mg2Si, Al4MgY, and a small amount of Al12Mg17 phases. The coarse dendrites, reticulated eutectic structures, and massive phases in the coatings were refined and distributed more uniformly with the increased amount of Y2O3. Y2O3 addition improved the microhardness, wear resistance, and corrosion resistance of the coatings.

Summary: The corrosion response of the Al-Si alloy/SiC foam interpenetrating phase composite (IPC) was investigated. SiC foams with different pores per inch (PPI) index were used to fabricate the IPCs. The corrosion resistance deteriorated in all the IPCs except for 20PPIC due to the incorporation of the reinforcing phase, which resulted in the formation of a less disrupted passive film and restricted pit growth.

Summary: The influence of trace Si on the microstructure and corrosion behavior of as-cast Mg-0.4Mn-xSi alloys has been studied. It was found that the presence of trace Si leads to the formation of MnSi, Mn5Si3, and Mn3Si phases, thereby significantly increasing the corrosion rate of the alloys. During corrosion, rod-like MnxSiy precipitates exhibit stronger cathodic activation behavior compared to block-like precipitates.

Summary: This study proposes a new antibacterial mechanism, showing that the antibacterial effectiveness of alloys is proportional to the micro-area potential differences on their surface. By designing different alloys to eliminate the antibacterial contribution of copper and silver ions, it was found that high micro-area potential differences lead to the production of reactive oxygen species, resulting in antibacterial effects.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.
