Summary: In this study, the reactions between 2-furfuryl alcohol (2FFOH) and OH radical were investigated by quantum chemical calculations. The energy diagram and rate coefficients of the reactions were calculated at different temperatures and pressures. The results showed that H-abstraction from the side chain of 2FFOH occurred faster than from the ring below 2300 K. Additionally, there was a slightly positive pressure dependence of the total rate coefficients in the temperature range of 500-1000 K. The findings of this study could contribute to the understanding of the chemical reaction mechanism of furan-based fuels in the atmosphere and combustion.

Summary: The treatment of NOx has become an urgent issue due to its difficulty in degradation in air and its negative impact on public health. Among various technologies, selective catalytic reduction (SCR) using ammonia as the reducing agent is considered as the most effective and promising technique. However, the development of high-efficiency catalysts for SCR is severely limited due to the poisoning and deactivation effect by SO2 and H2O vapor. This review summarizes the recent advances in enhancing the catalytic activity and stability of manganese-based catalysts in low-temperature NH3-SCR, as well as discussing the challenges and potential solutions for designing a catalytic system with high resistance to SO2 and H2O.

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.
