Summary: This study investigated the nano-scale spatial distribution of natural organic matter (NOM) on iron (hydr)oxides surfaces and its impact on oxyanion and metal cation adsorption. The results showed significant deviations between the MSM and NOM-CD models for oxyanions due to the competitive effect of NOM binding to oxides. Conversely, for metal cations binding mainly to NOM, the influence of NOM-mineral interaction on adsorption was minimal, resulting in similar results between the two models.

Summary: In this study, first principles calculation combined with scanning electron microscopy (SEM) was used to investigate the mineral dissolution mechanism of Mg2SiO4 promoted by different types of organic acids. The results show that the hydroxylation of the mineral surface is caused by the breaking of the H-O bond in the carboxyl group of the adsorbed organic acid molecules, and a greater number of carboxyl groups is more favorable for mineral dissolution.

Summary: This study aimed to investigate the aging characteristics of disposable surgical masks (SMs) and the effect of different aged layers of SMs on phenanthrene (PHE), tylosin (TYL), and sulfamethazine (SMT) under urban environmental stressors. The results showed that UV exposure caused more severe aging of the SM layers than ozone, and the middle layer made of melt-brown fabric displayed the highest degree of aging. The findings highlight the environmental effects of new microplastic sources and coexisting pollutants under the influence of COVID-19, contributing to the accurate evaluation of the biological toxicity of SMs.

Summary: The study aimed to improve the efficiency of heavy metal adsorption using biochar-based materials. A composite material (BC-LDH) was prepared by loading MgAl-layered double hydroxide (MgAl-LDH) onto coconut shell biochar (BC) for the decontamination of Pb(II) and Cu(II) in water. The BC-LDH exhibited higher removal capacities for Pb(II) and Cu(II) compared to BC and LDH. Characterization results revealed that the interaction mechanisms between BC-LDH and heavy metals included mineral precipitation, cation exchange and isomorphic replacement, electrostatic attraction, and surface complexation.

Summary: A new adsorbent, PVA/GO composite, was prepared and used for the removal of Sr2+ from aqueous solution. The unique architecture of PVA/GO significantly enhanced the adsorption capacity toward Sr2+ and conformed to pseudo second-order kinetic model, Langmuir model, and Freundlich model. The complexation interaction between Sr2+ and oxygen atoms/p-electron domain of PVA/GO composite was primarily responsible for the adsorption mechanism.

Summary: Hydroxyl radical (center dot OH) and sulfate radical (SO4 center dot-) have been widely studied in advanced oxidation processes (AOPs) for organic pollutants degradation. In this study, a Co(II)/peroxymonosulfate activation system was established to degrade caffeine (CAF), and the different attack routes of SO4 center dot- and center dot OH were explored. It was found that SO4 center dot- is more likely to attack CAF kinetically, while only center dot OH can react via hydrogen atom abstraction (HAA) route. Radical adduct formation (RAF) is the most favorable route for both center dot OH and SO4 center dot- attack. These findings provide insights into the degradation mechanism of organic pollutants in AOPs driven by center dot OH and SO4 center dot-.

Summary: This study systematically investigated the changes in characteristics and composition of dissolved organic matter (DOM) under UV/PAA treatment, as well as the underlying mechanisms. UV/PAA treatment significantly reduced the aromaticity, apparent molecular weight, and fluorescent abundance of DOM, while producing more oxidized and saturated compounds. The reactive species (.OH and CH3C(O)O./CH3C(O)OO.) play a primary role in DOM changes, but with differences in reaction selectivity and mechanisms.

Summary: The catalytic activity of Fe-NxC4-x sites with different coordination environments was predicted through theoretical calculations. Substituting N with C to coordinate with Fe atom resulted in inferior Fenton-like catalytic efficiency. Three configurations of Fe-SACs (Fe-N2C2, Fe-N3C1, and Fe-N4) were fabricated and showed that optimized Fe-NxC4-x coordination environments significantly promoted Fenton-like catalytic activity. The coordination dependency of Fe-SACs was also observed in terms of catalytic stability and actual hospital sewage treatment capacity. This strategy of local coordination engineering provides an example of how to modulate SACs with well-regulated coordination environments to maximize their catalytic efficiency.

Summary: The study focuses on the research hot topic of effectively degrading organic dye pollutants in water. CexZryO2 nanocomposites with different ratios of niobium and zirconium were synthesized using a non-stoichiometric and hydrothermal method, and their performance in the photodegradation of organic dyes was examined. By analyzing the band gap energy and specific surface area through solid-state ultraviolet analysis, the factors influencing the catalytic rate of the catalyst in the photocatalytic degradation of methylene blue (MB) were investigated. The highest degradation efficiency for MB, reaching 99.04% within 120 minutes, was achieved with a Ce/Zr molar ratio of 9 : 1 among the CexZryO2 nanocomposites series.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

The reaction mechanism involves complex reaction orders for the oxidant and the aromatic aldehyde, while the reaction order for Ru(VI) is one. The proposed mechanism includes two catalytic cycles and the formation and decomposition of complexes.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.

The study reveals that by exciting the nanocomposites within their absorption band, a control over effective optical nonlinearities can be achieved, allowing the modification of the magnitude and sign of the effective nonlinear absorption coefficient. The proposed strategy using metal-alkanoates based glass-forming ionic liquid crystals and nanoparticles shows great potential for the development of nanophotonics and plasmonics technologies.
