Summary: Polymer inclusion membranes (PIMs) based on PVC and poly(ethylene-co-vinyl acetate) (EVA) were prepared and investigated for Cr(VI) extraction from aqueous media. The composition of PIMs was optimized and the physical-chemical properties of the resulting membranes were analyzed. The results showed that PIMs containing EVA40 and PVC were more efficient for Cr(VI) extraction compared to those with only PVC. The addition of tetradecanol improved the water plasticizing effect and increased the stability of the membrane.

Summary: Recently, palladium has been widely used in various industries such as electronics, catalysis, electroplating, and fuel cells. As the scarcity and high price of precious metals have made their recovery crucial, the adsorption method in polymer inclusion membranes has proven to be effective and simple. In this study, different base polymers, carriers (Aliquat 336, trioctylamine (TOA)), and plasticizers (2-nitrophenyl octyl ether (NPOE)) were used to produce and characterize polymer inclusion membranes. The palladium adsorption capacities of the membranes were examined in detail under different conditions, and the best results were obtained for specific membrane compositions.

Summary: In this study, micro polymer inclusion beads (mu PIBs) containing D2EHPA were characterized by TGA for the first time, and their extraction performance for La3+ was evaluated. The TGA method was used to determine the exact composition of mu PIBs, and it was found that PVC- or PVDF-HFP-based mu PIBs underwent negligible D2EHPA leaching during fabrication. The presence of Na+ in mu PIBs had a negative impact on the extraction of La3+, which could be overcome by washing the mu PIBs with 1 M sulfuric acid.

Summary: In this study, various analysis methods were used to investigate the mechanical activation mechanism of titanium-bearing blast furnace slag. The results showed that the specific surface area of the slag increased significantly during mechanical activation, accompanied by an increase in lattice distortion and a decrease in unit-cell volume. Additionally, the cumulative volume of medium particles in the activated slag was significantly higher, which was beneficial for subsequent leaching processes. The optimal mechanical activation parameters were determined, and the mechanical activation mechanism was analyzed.

Summary: An innovative recycling strategy is proposed to address the excessive chemical consumption and secondary pollution in the wet chemical recycling process of spent LiFePO4 batteries. The strategy involves sustainable proton circulation between organic leachants, extractants, and strippants to regenerate expensive organic leachants and reduce secondary pollutants. Through experiments and analysis, it is found that monocarboxylic acids with low pKa and short carbon chains are effective in leaching lithium from the battery powder. The study also explores direct separation of lithium from organic leachates and successful regeneration of organic acids through proton exchange equilibrium.

Summary: This work investigates the effect of an advanced electrolyte additive on the performance of Ni-rich LiNixCoyMn1-x-yO2/graphite batteries. The results show that the additive induces the formation of robust electrolyte/electrode interphase, significantly improving the cycling performance and reducing the cell impedance. The capacity retention rate of the cells with the additive-based electrolyte can reach 90% after 600 cycles, which is considerably better than that of baseline batteries (70%). Mechanistic studies reveal that the additive suppresses the formation of fragile Li2CO3 and promotes the formation of more stable LiF, LixPOyFz, and additional organic phosphorus species on the electrode surface, thereby preventing cation disorder and irreversible phase transitions.

Summary: Vanadium oxides were reconstructed as advanced cathode materials for AZIBs using a dual-vapour-thermal engineering strategy. The ethanol/water dual-vapour phase triggered the fast formation of oxygen-deficient vanadium oxide hydrates (VPH-VO) with rich bound water pathways, which shielded the electrostatic interaction within the lamellar [VOn] host and facilitated Zn2+ diffusion. The VPH-VO cathode showed outstanding capacity and high-rate cycling stability, making the dual-vapour-thermal engineering an efficient approach for high-performance AZIBs.

Summary: Although both electromagnetic and charge transfer mechanisms play a role in surface-enhanced Raman scattering (SERS), the contribution of charge transfer is limited by poor efficiency. This study introduces molecular-enhanced Raman spectroscopy (MERS) and demonstrates a simple strategy to achieve strong charge transfer-enhanced Raman signals using a phosphoester electron-transfer bridge. The results show that MERS can significantly enhance Raman signals and offer a potential solution for highly charge transfer-enhanced Raman signals.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
