Summary: Inorganic CsPbX3 perovskite quantum dots show excellent photoelectric properties, but poor stability limits their applications. In this study, CsPbBr3 quantum dots were precipitated in a phosphate glass matrix, and the influences of Mn2+ and Eu3+ dopants on their microstructure and optical properties were investigated. The results showed that Mn2+/Eu3+ doping could promote the precipitation and improve the optical performance of CsPbBr3 quantum dots glass.

Summary: This study fabricated symmetric mixed-matrix membranes by employing zeolite A-3 dispersed in a polyether sulfone (PES) matrix through solution casting technique. The impacts of zeolite loading and annealing temperatures on thermal stability, morphology, and carbon capture performance of the membranes were systematically investigated. Compared to the pristine PES membrane, the incorporation of 30 wt% optimal zeolite loading into the polymer matrix enhanced the CO2 permeability from 81 to 128 Barrer, and the CO2/N2 selectivity from 9 to 22. Annealing the composite membranes at 155 degrees C further improved the CO2 permeability, but at the expense of reduced CO2/N2 selectivity.

Summary: TiO2 films were deposited on fiber-cement surfaces using the doctor blade technique. The films exhibited homogeneous and nanoparticulated morphology. The TiO2-PC105 film had lower roughness compared to the TiO2 P25-based film. Both films showed high hydrophilicity under UV-A radiation. The TiO2-PC105 film had a photonic efficiency of xi = 0.1%, while for the TiO2-P25 films, xi = 0.08%. The PC105 film modified cement surface exhibited high antimicrobial activity. The results demonstrate the self-cleaning ability of the films and their potential for protecting fiber-cement surfaces.

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.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. 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.
