Summary: This work investigates the structural, morphological, and photocatalytic properties of titanium dioxide (TiO2) and TiO2:NiIn (T-NiIn) coatings fabricated by spin coating. The results show that T-NiIn coatings exhibit higher effectiveness in the degradation of eosin-yellowish (EY) dye under both UV irradiation and solar light, and also show better stability after multiple cycles of reuse. The incorporation of nickel (Ni) and indium (In) in TiO2 coatings offers a feasible strategy to enhance the degradation of EY dye in drinking water.

Summary: Low-dimensional Ga2O3 was synthesized through a simple chemical route, allowing for easy tuning of morphology. Different Gallia precursors led to spherical nanoparticles and fractured nanobricks as the end product. Despite their wide bandgap, both samples showed efficient visible-light-induced photocatalytic degradation of toxic organic pollutants due to sensitization of the dyes. The nitrate-salt-originated nanobricks exhibited higher degradation efficiency towards rhodamine B (RhB) compared to the chloride-salt nanospheres, attributed to their electronic band positions and morphological features such as higher specific surface area, porosity, and aspect ratio. This remediation technology can be applied to optimize future catalyst systems for wastewater treatment fabricated via the hydrothermal-synthesis route.

Summary: This study aims to fabricate self-doped Ti3+-TiO2 microspheres and dye sensitized self-doped Ti3+-TiO2 composites with high surface areas and visible-light absorption for highly enhanced photocatalytic tetracycline degradation under visible-light irradiation. The experimental results showed that the obtained Ti3+-TiO2 microspheres showed enhanced visible-light capture capacity and a larger surface area. Besides, the obtained Eosin Y/Ti3+-TiO2 composites showed efficient visible-light absorption and highly boosted photocatalytic performance towards tetracycline degradation. The highest rate constant for Eosin Y/Ti3+-TiO2-9% composite reached as high as 0.06657 min-1, approximately 8.09 times that of commercial TiO2, strongly demonstrating the significant roles of dye sensitization. Finally, a reasonable dye sensitization visible-light photocatalytic mechanism was suggested.

Summary: The study presents a highly efficient nanocomposite based on titania for dye-synthesized solar cells (DSSCs). The nitrogen-cobalt-cadmium-doped titania (N-Co-Cd-doped TiO2) prepared using the sol-gel method significantly enhances the photoelectric properties of DSSCs. Material characterization techniques such as scanning electron microscopy and X-ray spectroscopy reveal the surface morphology, composition, and phases of the prepared N-Co-Cd-doped TiO2 nanocomposite. The current-voltage measurements confirm the improved charge transport in DSSCs using N-Co-Cd-doped TiO2, and the power conversion efficiency in fluorescent dye reaches 5.4% (approximately eight times higher than TiO2).

Summary: The use of TiO2 nanoparticles for photocatalysis for the degradation of organic dyes under UV light for wastewater treatment has been widely studied. However, the photocatalytic characteristics of TiO2 nanoparticles are inadequate. In this study, three types of nanoparticles (TiO2, ZrO2, and mixed-phase TiO2-ZrO2) were synthesized and their properties were examined. The results showed that the mixed-phase TiO2-ZrO2 nanoparticles exhibited higher photocatalytic activity for the degradation of Eosin Yellow under visible light compared to TiO2 and ZrO2 nanoparticles.

Summary: The study investigates the performance of SMBR in reversible reactions and finds that both kinetics and adsorptive separation are important factors. Non-isothermal operation can significantly improve unit throughput under certain conditions, while feed concentration and reaction enthalpy have minor effects on the optimal solutions. Decision variables based on flow rate ratios and internal concentration profiles can explain the trends of Pareto optimal solution.

Summary: In this study, the physical, chemical, and biological characteristics of liquid and solid streams generated by different filter configurations were compared. The results showed that the RBF, DF, and PC all had different removal efficiencies for total suspended solids. The liquid fractions also underwent significant compositional changes, while the biodegradability of the liquid fractions remained constant. The recovered solids from RBF had higher TS concentration and VS content compared to DF and PC treatments. The biodegradability rate of DF and PC sludge was higher than that of solids recovered by RBF.

Summary: The agricultural industry uses a large amount of water for irrigation, but excessive use of pesticides has led to the issue of wastewater contamination, which is a global problem. Pesticides not only have negative impacts on human health, the ecosystem, and the aquatic environment, but also react with water and soil to form substances with different properties. Although there are biodegradable pesticides, their use is limited and natural degradation is time-consuming. The development of environmentally friendly pesticides and new technologies to reduce water contamination is becoming increasingly important.

Summary: The rapid fabrication of high-performance composite membranes based on CMPs using simple and low-cost methods is challenging. In this study, three CMPs-based composite membranes were rapidly fabricated with adjustable size using unidirectional diffusion synthesis. The microstructural design enhanced the rejection rates of the membranes and they showed strong hydrolytic resistance, thermal stability, and acid-base resistance. Electrostatic adsorption and the adjustable microstructures significantly varied the repellence of the membranes to different charged molecules.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
