Summary: The presence of polycyclic aromatic hydrocarbons (PAHs) in wastewater, especially acenaphthene (ACN), has become a major concern due to their potential negative health effects. This study used activated carbon from oil palm leaves to remove ACN from wastewater through adsorption. The optimization of pH, activated carbon dosage, and contact time was conducted using response surface methodology (RSM) combined with central composite design (CCD). The results showed that pH 7, an activated carbon dosage of 2.62 g/L, and a contact time of 71.67 min were the optimal conditions for achieving a removal efficiency of 98.88%. The RSM model was found to be significant, allowing for the prediction and verification of the adsorption results.

Summary: With the continuous growth of the olive oil industry, the management of olive mill wastewater (OMW) by-products has become a topic of great interest. In this study, a composite of a Cu 1,4-benzene dicarboxylate metal-organic framework (Cu (BDC) MOF) and granular activated carbon (GAC) was used as an adsorbent for removing total phenolic content from OMW. The experimental results showed that the maximum adsorption capacity was 20 mg/g of total phenolic content (TPC) after 4 hours of treatment using 2% wt/wt GAC/Cu (BDC) MOF composite at pH 4.0 and 25 degrees C. The adsorption reaction was described by the Freundlich adsorption and pseudo-second-order reaction models, and it was found to be spontaneous and endothermic. The findings of this study provide a potential solution for the olive oil industry worldwide.

Summary: Tetracycline is one of the most widely used antibiotics in human therapy, veterinary applications, and agricultural activities. Its consumption is expected to increase by over 30% by 2030. This review focuses on the recent advancements in photocatalytic degradation of tetracycline using graphitic carbon nitride-based photocatalysts, which offer higher visible light activity, low cost, and non-toxicity. The properties, worldwide consumption, occurrence, and environmental impacts of tetracycline are comprehensively discussed. The occurrence of tetracycline in various water matrices has been confirmed, with a maximum concentration of 54 μg/L. Among different graphitic carbon nitride-based materials, heterojunctions have shown the highest photocatalytic degradation efficiency of 100% with reusability for up to 5 cycles. Photocatalytic membranes are found to be feasible due to ease of recovery and better reusability. The limitations and efficient solutions for graphitic carbon nitride-based wastewater treatment technology are also emphasized in detail.

Summary: Modeling of treatment wetlands allows the prediction of system behavior and facilitates large-scale design. In this study, applicable models for vertical flow (VF) and horizontal subsurface flow (HSSF) wetlands in a hybrid wetland (HW) system were calibrated and verified. Simulations showed the dependence of nitrification on NH4+-N availability and the impact of organic nitrogen and COD loading on nitrification efficiency in the VF stage. In the HSSF stage, simulations demonstrated the positive impact of hydraulic or pollutants loading rate on system performance. The satisfactory fit of the models and the useful tool provided by simulations for evaluating the performance of the HW system in different operating scenarios.

Summary: Wastewater treatment and reclamation are crucial for sustainable water resource utilization. Zeolite-based heterogeneous catalysis holds great promise in overcoming current limitations and advancing practical water treatment. This paper summarizes the synthesis methods, advantages, and disadvantages of zeolite-based catalysts. In comparison with traditional Fenton-like reactions, zeolite-based catalysis offers advantages of reduced sludge, wide pH range, and easy recyclability. The paper reviews the applications of zeolite-based Fenton-like catalysis (ZFCs) in pollutant removal and wastewater reclamation, emphasizing methodological strategies for improving ZFCs, such as incorporating external driving forces (e.g., photocatalysis or electrochemistry) and introducing transition metals into zeolite-based catalysts. Possible challenges and future perspectives for ZFCs are proposed.

Summary: Reduced graphite oxide (rGO) materials have shown great potential in advanced oxidation processes for the catalytic degradation of organic pollutants in water. The application of rGO as a metal-free catalyst in the Fenton reaction depends on its degree of reduction. This study prepared rGO using the modified Hummers' method and two-step reduction via hydrothermal and calcination processes. The effectiveness of as-prepared rGO as a photocatalyst and metal-free catalyst for decolorization of various textile dyes was investigated, and factors such as catalyst dose, pH, and initial dye concentration were examined. The recyclability of rGO in the photocatalytic system was also examined.

Summary: MIL-53(Fe) was synthesized as a three-dimensional metal-organic framework with different precursors-to-solvent ratios, denoted as MIL53B and MIL53C. Modified versions, MIL53B/NH2 and MIL53C/NH2, with varying NH2 ratios (0.10, 0.20, and 0.30), were also prepared using organosilane. The materials were characterized using XRD, SEM, EDS, and FTIR techniques, and their adsorption capacity for dye (Direct Red 23) was studied. The modified MIL53 showed higher adsorption capacity (4,989 mg/g) compared to the unmodified version (1,375 mg/g), indicating its potential as a dye adsorbent and for removing similar organic molecules from contaminated water.

Summary: This study investigates the influence of the flexible spacer parity of a guest photoactive liquid crystalline dimer on the photonic bandgap features of the cholesteric and twist grain boundary smectic C phases of the host molecule. The results show that the parity of the photoactive dimer affects the width of the photonic bandgap and the blue-shift of the cholesteric phase. Additionally, the parity of the dimer also affects the layer spacing and two-dimensional periodicity of the liquid crystalline phases.

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. Quantitative structure-activity relationship analysis showed that deactivating groups in the para-position enhance the process.

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.
