This review comprehensively analyzes recent advancements in aqueous bismuth-based batteries (ABBs), focusing on anion-mediated storage mechanisms involving hydroxyl, halide, sulfide, phosphate, and carbonate ions. Key advantages of bismuth include low toxicity, cost-effectiveness, minimal volume expansion, and multi-electron redox capabilities enabling high theoretical capacities. However, practical deployment remains hindered by capacity fade, insufficient mass loading, and electrolyte instability. The discussion highlights material design strategies, such as nanostructuring, heterojunction engineering, and lattice strain modulation, to enhance conductivity, cycling stability, and rate performance. Comparative analyses reveal trade-offs between charge carrier kinetics, capacity, and stability with halogen-based systems excelling in rate capability and multivalent anions offering higher capacities. The further challenges and further prospects are also discussed in the end.

The materials were tested for their ability to reduce hexavalent chromium Cr(VI), a toxic pollutant, to the less harmful trivalent chromium Cr(III) under natural sunlight, using formic acid as a hole scavenger. The Ni₁₂P₅ and Ni₁₂P₅-rGO catalysts achieved complete Cr(VI) reduction in 160 and 130 min, respectively.

Conventional metallic materials such as stainless steel, zinc-rich alloys, cobalt-based alloys, and titanium alloys often present limitations, including stress-shielding effects and the release of hypothetically harmful metal ions. On that account, Mg-based bioactive materials have garnered significant attention due to their critical functions in enzymatic reactions and degradational activity during tissue healing. Researchers have been actively developing and characterizing Mg-based biomaterials with tailored compositions to precisely regulate degradation kinetics, biodegradability, and tissue regeneration potential to revolutionize surgical procedures. However, the uncontrolled degradation of Mg can lead to premature loss of mechanical integrity, excessive release of metal ions, and excessive hydrogen gas evolution in peri-implant tissues, all of which can compromise biocompatibility and implant functionality. To address these limitations, innovative protective strategies such as surface coatings and alloying modifications have been discussed for their role in enhancing the durability and biocompatibility of Mg-based implants. This review further highlights the emerging field of magnesium nanoparticles, showcasing their biocompatibility and tunable release properties, making them promising candidates in targeted drug delivery, bioimaging, and wound healing applications. Furthermore, the anticancer potential of magnesium oxide (MgO) nanoparticles is investigated, with particular emphasis on their ability to inhibit cancer cell proliferation and induce apoptosis, thereby opening novel prospects in oncological research and therapy.
