Summary: Benzisothiazolinone degrades faster in soils with higher organic matter content, with anaerobic microorganisms playing a more significant role in degradation compared to aerobic microbes. Two metabolites were identified during the degradation process for the first time. Additionally, BIT exhibits relatively strong sorption and low persistence in soils, posing a low potential risk for groundwater contamination.

Summary: The effect of encapsulating LaNi4.5Co0.5 powdered hydrogen storage material with a 0.5μm thick amorphous film of TiCrFeCoNi high-entropy alloy (HEA) on the functional hydrogenation parameters of the hydride electrode is discussed. The presence of the HEA coating decreases the capacity but increases the exchange current density for the H2O/H-2 system. The effect on capacity fade is uncertain but the HEA coating significantly improves the high rate discharge ability (HRD) of the electrode material.

Summary: The stable electrochemical potential window of thiolate self-assembled monolayers (SAMs) on Au, Pt, and Cu electrodes is studied systematically in aqueous electrolyte systems. The reductive stability is found to depend on the binding strength of sulfur and competitive adsorption of hydrogen, while the oxidative stability is related to each surface's propensity toward surface oxide formation. The stability of SAMs is also influenced by factors such as SAM defects, intermolecular interactions, SAM thickness, and the ability to directly oxidize or reduce the non-sulfur part of the SAM molecule.

Summary: This study investigated the sorption mechanisms of the popularly occurring carbamazepine (CBZ) on pristine and aged microplastics (MPs). The aging process of MPs increased their sorption capacity and intensified the desorption hysteresis of CBZ. The XDLVO theory was applied to calculate the interfacial free energies and revealed that the hydrophobic interaction was lessened after aging for all MPs.

Summary: The study found that adding biochar could increase soil pH and saturated moisture, while aged biochar had more oxygen-containing functional groups and exhibited higher hydrophilicity and polarity. The sorption mechanism of unamended soil with SPY primarily resulted from the weak hydrophobic distribution. Both fresh and aged biochar-amended soil increased SPY sorption due to improved H-bonding interaction between SPY and biochar surface functional groups.

Summary: This study investigated the effects and mechanisms of microplastics (MPs) on the sorption-desorption, bioaccessibility, and bioavailability of cadmium (Cd) in paddy soil. The experiments showed that MPs significantly reduced Cd sorption in soil by covering the soil active sites and interrupting formation of CdCO3 and Cd3P2 precipitates. This led to an increase in Cd bioaccessibility and bioavailability in soil. The findings provide new insights into the impacts of MPs on the fate and risk of heavy metals in agricultural soil.

Summary: The study found that the sorption behavior of chlorothalonil in urban soils is influenced by soil properties, with soil organic matter, silt, clay, and oxides of aluminum and iron showing a significant positive correlation with chlorothalonil's K-d value. In urban soils, the decreased sorption of chlorothalonil is mainly attributed to the presence of organic matter, while the increased sorption may be related to factors such as organic matter, clay, aluminum and iron oxides, as well as the fungicide's hydrophobicity.

Summary: A simple parametric model was developed to predict the sorption of perfluoroalkyl substances (PFASs) in soils, filling gaps in existing databases and showing that sorption mechanisms depend mainly on PFAS chain length. The model was validated to predict PFAS sorption based on soil OC, silt+clay contents, and PFAS chain length for risk assessment in soil contamination events.

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.

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.
