Summary: Copper(I) mixed-triazolate frameworks with thiophene-containing triazole ligands were synthesized and evaluated as photocatalysts for degrading organic pollutants in water. One of the frameworks, CuMtz-1b, showed significantly improved degradation efficiency for various organic contaminants and comparable degradation rates to framework CuTz-1 with H2O2 addition under different light sources. The enhancement in degradation efficiency was attributed to the increased light absorption ability and band structure changes caused by the thiophene-containing triazole ligands incorporated in the framework.

Summary: Efficient cathode-ray scintillation coordination polymers with good stability at high voltage were prepared by conjugating luminescent groups with d(10) metal ions. The synergistic effect of inorganic metal and organic ligand suppresses the self-quenching of the conjugated luminescent groups and enhances the scintillation performance. This work provides new ideas for the design of new field-emission displays and cathode-ray scintillation materials.

Summary: Two functional fluorinated ligands were synthesized by modifying a fluorinated benzoic acid, leading to the construction of two isostructural 3D Cd2+ coordination polymers with excellent chemical and thermal stability in water systems. One of the polymers showed more efficient fluorescence sensing towards tetracycline with a lower detection limit and rapid response in comparison to the other. The fluorescence quenching mechanism was explored through experimental data and density functional theory calculations.

Summary: This study investigates the potential of magnetic metal-organic frameworks (MMOFs) as a seed in assisting polymeric ferric sulfate (PFS) flocculant for the remediation of algal-contaminated water. The results show that MMOFs have good dispersion and stability in acidic PFS solutions, and their bonding with PFS enhances the coagulation effect. Coagulation with PFS-MMOFs is effective under different hydraulic conditions and shows better results in terms of dissolved organic carbon (DOC) removal and ultraviolet absorption value at 254 nm (UV254) compared to PFS alone, particularly in algal-infested waters. Therefore, MMOFs can serve as excellent magnetic seeds for PFS, potentially improving the effectiveness of conventional coagulation methods.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
