Summary: This study evaluates the role of gas-phase water in the degradation of trifluoromethyl peroxynitrate and trifluoromethyl nitrate for the first time. Experimental results show that water vapor does not affect the stability of peroxynitrate, but it promotes the degradation of nitrate to form other compounds.

Summary: The Gulf Cooperation Countries (GCC) face challenges of limited fresh surface water resources and over-exploitation of groundwater, leading to increased reliance on seawater desalination. However, the high relative humidity and temperatures in the region offer great potential for atmospheric water generation (AWG). This study evaluates scalable AWG techniques, including direct air cooling using Vapour Compression Refrigeration Systems (VCRS) and Air Conditioner Condensate Recovery (ACCR). Field tests conducted in Masdar City, UAE showed promising results and demonstrated the potential of AWG as a complementary option to desalination without generating brine.

Summary: This study proposes a method to estimate water vapor density by utilizing the received signal level (RSL) of commercial microwave links (MLs) at frequencies below 20 GHz, with a high measurement resolution and correlation with automatic weather stations. The method trains a sensing model with support vector machine, and is capable of directly estimating water vapor density from RSLs without preprocessing, indicating its potential for refined data on water vapor density and contribution to atmospheric boundary layer research and numerical weather forecasting.

Summary: The study investigates the contribution of water dimers to the self-continuum absorption spectra of water vapour, finding that water dimers may account for up to 50% of the observed continuum within specific bands. A derived dimer-based model shows a higher effective equilibrium constant compared to modern estimates, leading to a reduction in calculated surface irradiances by 0.016 W m(-2) in the 8800 cm(-1) band and a 12.5% enhancement of the self-continuum radiative effect under certain conditions.

Summary: This work presents a spectrally resolved Raman lidar for simultaneous measurement of volume backscattering coefficient spectra of atmospheric three-phase water and fluorescent aerosols. The lidar emits laser light and records both N-2 Raman echoes and spectral signals in a modified spectral range. By defining normalized spectra, a unique spectra decomposition approach is developed for retrieval of normalized spectra components of different substances. This study has the potential to accurately profile atmospheric water vapor and cloud liquid/ice water.

Summary: This study reveals a significant interdecadal change in the summer water vapor budget over Northeast Asia around the late-1990s, primarily influenced by a local anomalous anti-cyclone. The stationary component plays a dominant role in contributing to the total water vapor transport change, accounting for 84% compared to the transient component's 16%. The changes in water vapor budget are primarily attributed to the wind field change at the lower troposphere.

Summary: This study investigated the molecular characteristics of water-soluble organic matter (WSOM) in atmospheric PM in the range of 0.010-18 μm. A bimodal distribution of PM mass concentrations was found, with saturated fatty acids and their oxidized derivatives identified as the main carriers of CHO compounds. In hazy days, significant increases in S-containing compounds were observed, promoting particle agglomeration and haze formation.

Summary: In this study, the broadband spectra of the continuum absorption in pure CO2 gas and its mixture with Ar were investigated using a resonator spectrometer operating within the frequency range of 105-240 GHz at room temperature. The pressure and frequency dependence as expected were observed, and the obtained data were validated by two independent calculations. A simplified formula was proposed to describe the frequency and temperature dependency of the CO2-Ar continuum for atmospheric studies, covering a wide frequency range from 60 GHz to 450 GHz at temperatures from 200 K to 400 K.

Summary: The intensity of the atmospheric diagnostic fine-structure line of the O-2 molecule at 118.75 GHz has been revised through multiple measurements, confirming previous results and reducing uncertainty to about 0.3%. The agreement with calculations from HITRAN suggests that the recommended uncertainty of 10%-20% for all fine structure lines in the database is too large.

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.
