Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: Electrocatalysis has emerged as a significant research area in fields such as chemical catalysis, environmental research, and chemical engineering. Various catalysts, including transition metal oxide nanoparticles, transition metal nanoparticles, carbon-based nanomaterials, transition metal sulfides, porphyrins, and phthalocyanine molecules, have been used for electrocatalytic reduction of CO2. This review focuses on the CO2 reduction reaction and its products using transition metal sulfide nanomaterials. The main reaction products of CO2 reduction include carbon monoxide, formate/formic acid, methanol, ethanol, methane, and ethene. The type of transition metal-sulfide catalyst used in the reaction determines the products by controlling the intermediate species and reaction pathways. Experimental and computational methods are employed to study the CO2 binding and chemically reduced intermediates, which play a crucial role in the reaction pathways and are discussed in this review.

Summary: Transition metal oxide (TMO)-based anodes attract attention for lithium storage due to their high capacity, easy synthesis, and improved battery safety. The electrochemical performance of TMO anodes can be significantly improved through configurational entropy optimization. For example, a high-entropy oxide (FeCoNiCrCu)(3)O-4 with low potential and high capacity is synthesized. In both half-cell and full-cell configurations, the (FeCoNiCrCu)(3)O-4 electrode shows excellent performance with high specific capacity and low discharge voltage.

Summary: The surface atomic arrangement and defective structures of electrocatalysts play a crucial role in determining their catalytic activity and selectivity. In this study, alpha-Fe2O3 nanosheets with surface oxygen vacancies were synthesized and their oxygen vacancy concentration was varied to study their oxygen reduction reaction (ORR) performance. The results showed that increasing the oxygen vacancy concentration improved the ORR activity up to a certain point, but further increase deteriorated the crystalline quality and affected the performance.

Summary: Rechargeable sodium-air batteries have gained extensive attention and developed rapidly in recent years for electrochemical energy storage applications due to their low costs, abundance of precursor resources, and high energy density. However, challenges such as poor charge-discharge reversibility at the cathode and the formation of sodium dendrites at the anode still need to be addressed. Therefore, designing efficient and stable air cathode materials is crucial for the development and practical application of sodium-air batteries.
