Summary: This study addresses the challenge of dendrite growth in rechargeable aqueous zinc batteries by proposing a new zinc battery electrolyte, which can form an anode protecting layer with a biomimetic lipid-bilayer structure. This layer limits anode contact with water and offers fast zinc ion transport pathways, effectively suppressing dendrite growth while maintaining high rate capability. Additionally, a stable fluorinated solid electrolyte interphase is formed, further enhancing zinc reversibility. The electrolyte enables unprecedented cycling stability with dendrite-free zinc plating/stripping and shows good capacity retention.

Summary: Colloidal solution combustion synthesis (CSCS) is a simple and efficient method for mass production of crystalline nanomaterials with tunable pore structure. In this study, mesoporous Mn/CeO2 catalysts were successfully fabricated using the CSCS method combined with a dip-coating process. The prepared catalysts exhibited high photocatalytic activity for the oxidation of toluene under vacuum ultraviolet (VUV) irradiation. The analysis of intermediates suggested a possible degradation pathway. Physical and chemical characterization of the catalysts revealed that their properties play a crucial role in the photocatalytic activity. Compared to similar catalysts synthesized by other methods, the Mn/CeO2 catalysts demonstrated higher activity, attributed to the higher contents of specific species. This research demonstrated the effectiveness of the CSCS method coupled with a dip-coating process for the synthesis of high-performance catalysts.

Summary: Biogenic nano-hydroxyapatite (bHAP) has the potential to remediate heavy metal contaminated soil. However, little is known about the impact of anionic surfactants on bHAP transport in saturated porous media. This study explored the mobility of bHAP in sand columns with sodium dodecyl sulfate (SDS) and found that bHAP was transported in the presence of SDS, with mobility increasing with SDS concentration and pH. However, higher ionic strength hindered bHAP transport. The study provided a comprehensive understanding of bHAP transport affected by SDS, which is necessary for evaluating its efficacy in soil and groundwater remediation.

Summary: A novel Ag/MIL-68(In)-NH2/Bi4O7 plasmonic heterojunction was successfully prepared and showed the most efficient photocatalytic performance in the degradation of amoxicillin, with 3.7 and 3.2 times higher activity than Bi4O7 and MIL-68(In)-NH2, respectively. The superior performance was attributed to the large surface area and localized surface plasmon resonance (LSPR) effect, which provided more active sites and enhanced visible light absorption. The degradation pathway of amoxicillin was also investigated using Gaussian software calculation and liquid chromatography-mass spectrometry (LC-MS) analysis. Lastly, characterizations and simulations were conducted to explain the S-scheme photocatalytic mechanism.
